Which Of The Following Statements About The Dynamic Host Configuration Protocol Are True?
The dynamic host configuration protocol will be able to reduce the load of the manual allocation of the Ip address parameters. Today, let us discuss the dynamic host configuration protocol in detail. The Dynamic host configuration protocol can shortly be called the DHCP.
All the computers and communication devices have and unique IP address that can able to use for communication purposes. We can say that an IP address can be an identifier or any computer or device that is present on the internet.
Here, the assigning of the computer can be done in two ways. They are through the static IP addressing and the other one is the dynamic IP address. Now, let us know what is a static IP and what is a dynamic IP in detail.
The static IP can be called the traditional method at the beginning of the networking. Firstly we need to open the computer configuration page on each device that is present on the internet. And then we should manually type the Ip address along with the subnet mask of that particular IP address. We should also type the default gateway and the DNS server of it.
If we wanted to add the other device or computer to the network, we simply need to follow the same process. But this process of working may be too complex especially when we have a large area of the network. We have to ensure that all the IP addresses that are assigned must be unique.
An IP conflict may occur if we assigned the same IP address twice and it leads to removing the access from the network.
The best way to avoid this conflict is through the dynamic host configuration protocol. The dynamic IP can able to get the unique IP address automatically from the DHCP server.
It can able to assign the IP address automatically by taking it from the DHCP server. Along with this, it can also be able to assign the subnet maks default gateway, DNS server as it was done by the static IP.
So here we contain some of the network interface cards. So in the computer device, we have to set to obtain the IP address automatically.
Here when we choose the automatic option, the computing device would automatically send a request to provide an IP address for the network. After sending the request the DHCP server able to send the IP address and deliver it to the computer device that is present on the network.
After assigning the IP address, we can also able to check all the settings that the DHCP server has given to the computer. To check this, simply open the command prompt and then type IPconfig/all, and press enter.
Here we can see that the DHCP server is enabled on the computer, which means it can directly obtain the IP address from the DHCP server. We can also see the IP address, subnet mask, default gateway, DNS server on the command prompt.

What Are Two Functions Of Dynamic Routing Protocols? (Choose Two.)
The two main functions of the dynamic routing protocol are that frisky, it needs to maintain the networks along with the routing tables and we need to find the best-suited path.
For suppose, if we are the network administrator that of a network that is routed, then we may have some of the dynamic routing protocols in use. The dynamic protocol is the one that can automatically communicate with any number of the routers and finds all the routes that are present in order to communicate with the other routers that are available on the network.
This dynamic routing protocol will be able to provide all the subnet information that is present to the other side of the routers.
And hence, by using all this information, the router can find the best possible path that can be used to communicate with the other routers across the network.
The best possible path can be defined as the path that can able to forward the traffic around the network.
For suppose, if there is an outage that is present then the link will get down, and with the help of these dynamic routing protocols, we can able to reconverge and will able build the entire new set of the routes so that we can able to works through all the problems that are present on the network.
Only the router will be responsible for the best path that it is going to find in order to pass the information from one router to the other router. But this may be associated with lots and lots of variables that are combined through it.
Based on the status of the link, the router can able to find what path it is going to take. and it also determines how far it may go or take in order to make any particular connections.
These consist of a formula that is used by the routers in order to gather all the information about the network and note all the best paths that are present.
The convergence is also part that we should keep in mind if we want to use the dynamic routing protocol. here, some of the routing protocols may be able to converge very quickly and we should keep the network running and some of the other routing protocols has the ability to extend the amount of time that should be taken to rebuild the routes that we need to get operate.
For suppose, if we are connecting a number of different routes, we may choose some of the standard protocols that might be important for any particular manufacturer.
When we find the best possible paths through a formula, then we call it the distance vector routing protocols. By using this, each router may be able to decide the number of routers that are present between the location and the destination address that we are trying to find. The distance which we are going to use is called the deciding vector.

Which Connection Provides A Secure Cli Session With Encryption To A Cisco Switch?
An SSH connection provides the secure CLI session with encryption to the cisco switch. Today let us discuss bout the SSH connection in detail.
Now, let us configure the SSH session for the cisco switch or the route. We apply the same process for any kind of switch or router. Here, have five steps, let us discuss each step in detail.
Firstly, we need the hostname, domain name, and the creation of the SSH key or the generate key, creating of the user and we enable the switch.
Now open the command prompt and type enable and press enter and type conf t, now we can see that it displays as, enter the configuration commands. Now, we type the hostname coplex and we press enter.
Now we are going to the domain name, we type Ip domain-name coplex.co.uk and then press the enter button.
Now we are going to generate the key by simply using the crypto command like crypto key enter crypto key ge enter, and then crypto key generate RSA and then press enter.
Now, if already RSA keys are present it displays as already RSA keys are present and ask if we want to replace them. Then type Y and then press enter.
Now it asks how many bytes are present, so the bigger number that we give the stronger the key will be, and then the key will be generated after a few minutes.
After this, we try to enable the ssh session, now we type the line VTY 0 15. Here this has the channels of which remote we want to change it and then we simply press the enter button and type transport input Ssh and then press enter.
Here it will configure the switch and if we want to add andy additional user, we first simply exit from it and type create user name password and password name that we want to give.
And if we want to enable the local login, we again need to type the line VTY 0 15 and then press enter and type login local enter exit from it.
Now, after this, let’s test how does it work. Now if you have putty open the putty and give the IP address and open it. Now we can see the login command. since we haven’t set up any IP address, we give the user name and its password and this is the process of setting up the SSh session.
And if we want to set the IP address on the VLAN, we simply type the config enter and type configure t and type interface VLAN 1 enter and type the IP address and type the IP address we want to give and then press enter.
Here the Ip address should be of the same network as the computer until unless we use the nat, we use the same IP range, and hence this is how to set up the ssh session.

Which Method Is Used By A Pat-Enabled Router To Send Incoming Packets To The Correct Inside Hosts?
TCP or UDP port numbers are used by a Pat-enabled router to send incoming packets to the correct inside hosts. Today, let us study what is the pat enabled router, TCP, and UDP port numbers.
The term PAT stands for port address translation that can be commonly referred to as the Pat. The Pat is the third type of Nat. It can also be called the Nat overload. We can able to nat many inside local Ip’s into the one single global.
In simple words, we can say that we can able to nat the entire subnet of all the private IP addresses and we combine all them through a single public IP address.
We need to identify the inside nat and the outside nat interface, and the router should also know where the outer network, internal network, and the internetwork.
We have some of the primary differences among them let us know them in detail. Here, we can able to use one public IP for all the Nat translations that are present. For this, we need to take the entire subnet or several subnets and then we need to put them all behind a single public IP address.
Here, the pat can able to accomplish this by simply using the inside IP and by the inside port number. When we create the session, we get to know the IP address along with the port number.
Here the pat will take the information and it will map the unique port number that is present on the inside global IP.
Let us take an example to understand this concept in detail. For suppose, if we have the IP address called 192.168.1.2, now it will create the session. Now, this will be going to show some of the traffic from the port with the number 10005. Hereby using the pact the IP address like 201.2.2.1, it going to take the internal IP along with the internal port number. After this, it’s going to map them with port 12.
Now, all these can be called random ports. as from the above example, the port number will be able to identify the inside port numbers along with the inside IP address.
For suppose, for the same time if any other IP like 192.168.1.3 will also initiate the session into the device somewhere that is present on the internet. Now, it will start the source traffic from port number 30 1002, now this IP will be going to be mapped to the same public IP address like 201.2.21. In a similar way, we can able to map around more than 60000 IP addresses in the inside IP to the single public IP address.
Similar to the dynamic the configuration can be started with any command that we want, as we said earlier we already know that the single IP can able to handle the 60000 translations. Here we do not need to use a single public IP if we have many public IPs.

What Software Enables An Os To Communicate With Hardware?
The device driver enables the Os to communicate with the hardware. Now, let us discuss the device driver in detail.
In the concept of computing, a device driver is like a computer program, which can operate and can control the particular types of devices that are attached to the computer.
The device driver has the ability to provide the software interface as to the hardware interfaces that can able to enable the operating systems.
It can also enable the other computer programs in order to access the software functions without any help of knowing the hardware which is being in use.
The device driver has the ability in which we can able to communicate with the devices through the computer bus or through the computer subsystems to which the hardware can able to connect
For suppose, when a program calls a routine in the driver, the driver will issue the commands to the device after the data is sent back to the driver, the driver can able to invoke us in the original calling program drivers.
The program drivers are nothing but hardware-dependent and the operating system. All these typically will provide the interrupt handling that can be required for many interests like the time-dependent hardware interface.
Let us take an example to understand this in detail. let’s take a high-level application that can able to interact with the serial port for simply has the two functions with it. They are sending the data and then the receiving of the data.
And at the lower-level device driver will implement the following functions, it can able to communicate with the particular serial port controller that can be installed on the user’s computer.
And when we come to the modem hardware and the operating system drivers, it can able to operate in various different environments.
The driver can able to interface with the printers, video adapters, network cards, sound cards, and the local buses of various sorts. It can also interface with the low bandwidth IO buses and the computer storage such as the hard disks, cd- ROMs, floppy disks.
In order to implement the support for many different files systems, the image scanners, digital images. The device driver is simply referred to as the driver and called a computer program that can able to controls any type of device.
In order to access the hardware function, the device drivers are getting used. The main advantage of the device drivers is, we do not need to know any details about the type of hardware that is being used by enabling the operating system and the other hardware resources.
The main purpose of the device driver is to simplify the program that we use. It will act as the translator. The users can able to write the code independently to the device. The programmers can able to write the code even irrespective of the device the end-users are using. The communication can be done through a system called the communication system or through the bus.

Why Are Some Fastethernet Ports On The Switches Are Up And Others Are Down?
The FastEthernet ports are up to when its cables are connected to the ports and it will also be up in case if any network administrator has shutdown it manual. Otherwise, the FastEthernet ports will be down. Today, let us discuss how to add FastEthernet ports on the switches in detail. before we discuss the FastEthernet ports, let us actually know the fast ethernet ports in detail.
The rate of data transmission for a standard ethernet is 10 Mbps, we all know that there are some of the lan technologies that are present in the early 1990s, these can technologies can able to provide at the rate of 10 Mbps.
In order to reach the traffic, the ethernet has increased its speed by 100 Mbps. This rate of speed is called the fast ethernet. Here in order to achieve the speed of 100 Mpbs, the mac sublayer is simply kept unchanged.
This is nothing but the frame format of its remains the same. it is nothing but the maximum and its minimum size of its will remain the same.
The fast ethernet is simply used in order to increase the speed to 100 Mpbs and allows it to be compatible with the standard ethernet. This will keep the same address format and the same 48-bit address.
We do not use any bus topology in the fast ethernet. Instead of this bust topology, we use different topologies like the star topology and the hub.
The actual size is 2500 meters but it has changed it to 250 meters and we use the link-layer switch in order to use to store the frames and it will establish the full-duplex function.
Here the transmission medium can be provided for each host hence we can avoid the contention that it is leading and there is no need to use any CSMA or CDMA.
And the shared medium can be changed into many of the point-to-point media, hence the necessity of contention is simply not needed.
The main note in the FastEthernet is nothing but it must be able to compatible with the standard ethernet. We also use the auto-negotiation that will allow each device.
The main advantage of the fast ethernet is that we can able to connect all the small low-speed ethernet cards which are at 10 Mbps, can be connected to the high data rate ethernet cards, with a speed up to the 10 Mbps.
We can simply say that the fast ethernet is nothing but the extension to the 10 Mbps.We can run this fast ethernet through different cables like the optical fiber and the twisted pair cables. All the higher-level issues are solved by the fast MAC. the Mac stands for media access controller. That can be logically divided into the ethernet frame adapter.
Here we connect all the fast ethernet ports into the switches with its cables, so that the FastEthernet ports will be kept it as up.

Which Two Factors Influence The Method That Is Used For Media Access Control?
Firstly, the media access control will influence the nodes and then it shared the media. Today, let us discuss media access control in detail.
The media access control can be considered as one of the most important parts of the concept that we consider in networking.
Normally, we have many different ways in order to interconnect the nodes, like bus topology, star topology, and ring topology. All these are transferred through a medium. That means, the main point that we need to note is that the nodes which are sending the information to the other node are considered as a shared medium where it passes the information from one node to the other node in each one of these cases.
The transmission of the data can be done through three ways the unicast, multicast, and another one is broadcast. When we say the uniform transmission, we can say that the packet is only intended for the single packet. And the broadcast can be said that the packet can be intended for every one of it. And the last multicast will be intended to be the subset of all the nodes.
But in detail, who will intend the packets?. Now let us know that in detail. For suppose, when the medium has not present, it may cause a very big problem. That means the process of collisions may occur during the transmission from one node to the other node.
The main goal of the media access control is to determine how the nodes are getting to share the channel. It is like a protocol that can know or determine when a node can able to transmit it.
Many of the users assume that the media access control can able to broadcast the channel at a rate of R bps, which means if a single user wants to transmit the data, the users assume that the entire rate can be used for its transmission.
In a similar way, when all the N users want to send the information, then they need to utilize the R/M amount of the data rate.
The media access control protocol can be able to divide into many different smaller number parts, and each part of it gets allocated to each of its nodes in order to use it for any exclusive purposes.
That means an exclusive channel is maintained between the sender and then with the receiver. But if the channel is involved in any of the two nodes then we cannot send the data through these channels. And hence if the multiple stations access the channels then it may lead to a collision.
The main use of the multiple access control protocol is to avoid collision when the transmission of the data is being performed. They are also divided into different types like the random access control protocol, controlled access protocols, and then the channelized protocols. which are again subdivided into several protocols that help to reduce the collision during its transmission of the data.

When Creating Network Diagrams, What Icon Description Typically Represents A Network Switch?
A rectangular icon which is typical all the four icons are points in their opposite direction. now, let us discuss the computer network diagram, icon description, and the network switch in detail.
The computer networking diagram is simply like a schematic that is depicting on the nodes all the connections among all those that are in a computer network, or it can be any telecommunications network.
We use symbolization, readily identifiable icons are used in order to depict some of the network appliances.
The network appliances are nothing but the router and its style of lines that are being used, it will be able to indicate the type of its connection.
Mainly the clouds are used in order to represent the networks that is being external to the one. It is being pictured for the purpose of depicting the connections that is between the internal and the external devices. without even indication of the specification of the outside of the network.
Let us consider an example to understand this concept in detail. The hy[othetical local area network will be able to picture it to the right, all the personal computers and a server that is being connected to it through a wide area network link on the internet.
Depending upon whether the diagram is intended for formal or through informal use, all the certain details may be lacking it must determine the context.
It doesn’t indicate any of the physical types of the connection that is between the two computer devices and the switch that is associated with it.
But when the modern is get depicted, the ethernet maybe just assumed. If we use the same style of the wan diagram, this may indicate the physical connection.
At all the different scale diagrams, it may be able to represent the many levels of the network. At the local area network, many individual nodes are be represented through the individual physical devices like the file servers, hubs, or through the individual nodes that may represent the entire city.
additionally, when the scope of the diagram crosses the common LAN and the WAN boundaries, all the representative hypothetical devices may be depicted instead of showing all actually existing nodes.
If any network appliances are intended to be connected through any of the internets to any of the end-users, mobile devices only such type of devices that may be depicted for the purpose of showing all the general relationships that are between the appliance and any of such devices.
Cisco mostly uses its own type of brand of its networking symbols. here the cisco has a large internet presence and the designs of network devices. It is the list of all the symbols that are exhaustive.
The physical network topology will be directly represented by the diagrams, in the network we consider all the nodes as the vertices and all the connections can be directed or it can be indirected. And the logical network diagram can be inferred through the different network diagrams. by giving all the details of the network protocols.

Which Encryption Protocol Does Gre Use To Increase The Security Of Its Transmissions?
The IPsec encryption protocol does use to increase the security of its transmissions. Today, let us discuss how the GRE tunnels work in detail.
We have many VPN software that is installed on the computer devices, we can use this software in order to connect it to the offices, homes and many more.
The VPN tunnel is nothing but we try to build a tunnel in a network in order to increase the security of its transmissions. The term GRE stands for generic routing encapsulation, this gre is a type of VPN, but unlike other types of VPNs that are connected to the computer to the home or computer to the office. It will connect from one part of the network to the other part of the network.
Now, let us know where these gre’s are being used in detail. The main goal of the gre is to build the tunnel across the internet. These types of tunnels are mostly useful if we have any type of branch offices that we want to connect to the main site.
This GRE tunnel will cause much less than the lines that we need to put dedicated. We also have many other possibilities in the gre.
For suppose there are some of the network islands which we need to be brought together. For this to happen, there are quite a few reasons. By building, the network between these types of islands will allow it to create a virtual network. It will allow the virtual network by simply lowering the hop count.
Here we can also able to use the rip ar the middle of the network and can also use the OSPF between the networks. For suppose, if we have the Ip address the IPv6 for both the network islands, then the IPv4 network still can be with ipv4 address.
This Gre can able to carry the IPv6 traffic over the Ipv4 core. This gre has the ability to extend it to the wide-area network.
But there is still a chance that the wide-area network will not support some of the multicasts. Hence, in order to resolve this, we simply need to change the local area network so that it can able to support the multicast.
Here indirectly it can able to add some of the support to the dynamic routing.
Normally we need some of the hollow packets. Here, the main advantage of the gre is that we can able to use the gre with the DDos provider which we can able to sign up the with the provider and then the gre tunnel.
Here all the incoming traffic will may get-go to its first. By this, they can remove if any malicious has been seen and send rest to the gre tunnel.
The gre can able to control its edges and it has no control over the wan since it is managed by the service provider, but if we want to run, we simply need it to be connected to the workaround.

Which Statement Does Not Accurately Describe Characteristics Of The OSPF Protocol?
Many assume that OSPF requires a very little number of resources and fewer central processing units. Today, let us discuss the OSPF protocol in detail. The OSPF can be defined as it can be widely used and can be widely supported by many of the routing protocols.
It is known as the open standard meaning that means, it can be very much supported. It is like an integrated gateway protocol that means it has been designed to use a single type of autonomous system.
The OSPF can be also referred to as the link-state protocol. It is mainly used to discover the routes.
Now, let us know how the OSPF will perform this process in detail. The OSPF will first learn about every router and every subnet that is present within it. Hence, we get to know that every router will be having the same information about the network.
Here the routers will be able to learn about the information by simply sending the link state advertisements which can shortly be called the LSA.
All these link state advertisements will have the information about the subnet and some of the additional information in it.
The OSPF can able to store all the information in a database called the link-state database. This link state database can be shortly called the LSD.
The main goal of the OSPF is to maintain the same information in their LSDs.
But let us understand this in detail in order to know the working of it in more detail. It consists of mainly three steps. The first main step is to become the neighbors of the OSPF. Here all the neighbors will be connecting their routers and it running them through the OSPF.
The second main step is to exchange the information from the database. The routers will be able to transfer or exchange the data or information and at the third step, they will finally choose the best paths and the best paths.
After the exchange of its information, the router will be able to choose all the best routes to be added to the routing tables.
Now, let us know how to connect with all the enriches to the neighboring relationships. Here, each router will be able to choose a router ID, this router ID is the one that can able to identify the individual router.
here the router Id is in the same format as that of the IP address, we should firstly set that whether it is manually set or not. Here the router will try to choose the loopback Ip address. And if the loopback IP address is not found then we use to choose the nonloopback IP address.
Hence, we can say that it will be able to choose the highest IP address on the router itself.
The routers can be able to interact with the neighboring routers when all the OSPF and all the router IDs are configured. It normally includes the router Id along with the known neighbors to it.
