Implementation of the wireless connectivity will be the best extend access layer connectivity to host devices. Today let us discuss about the wireless connectivity in detail. Wireless connectivity normally allows you to connect to the various devices, This devices are nothing but the laptops mobiles computers printers and many more.
The devices helps us to share the files and data And helps us to access through the internet. The wireless connectivity will use the radio signals to transfer the data across the internet.
Now let us know some of the advantages of the wireless connectivity. We can easily be install the wireless connectivity and it is very costable and affordable to all the users. This wireless connectivity is more scalable when we compared to the wired connectivity.
The main advantage and goal of these wireless connectivity is said we can able to run multiple devices simultaneously. Now let us discuss about the operations that are formed by the wireless connectivity. Normally the wireless adaptor will able to receive the data from the computer and this wireless adapter translate the data into the form of radio signal.
Now this radio signal will be transmitted to the antenna, and the wireless router will receive this radio signal and will converts it and sends it to the destination address.
We also have the wireless personal area network which is shortly called as wpan, this wireless personal area network will be created by simply interconnecting all the devices within the area that are present. This wireless personal area network will be very secured and it is very reliable. The best example for this wireless personal area network are the remotes ,AC remote. But the wireless personal area network will be having less range and the data transmission will be very slow.
The wireless Local area network will combine two or more devices over less distance and connects all the users across the internet, we can easily able to add or we can easily able to remove the different work stations from the wireless Local area network. This wireless Local area network available to provide high data rate due to the small area coverage.
This wireless Local area network is also very economical because it has less area. The main disadvantages of these wireless Local area network is that it requires licence and it also take the Limited area and interactions may occur during the communication.
And we have wireless mesh network, this wireless mesh network will be organised in the mesh of apology. The main advantage of this wireless mesh network is that it is very robust in nature and we can easily be diagnosed any fault, it will also provide the security and ensure that the privacy in the network. And the main disadvantage of this wireless mesh network is that it is difficult to install and configuration of the connectivity.
And we have wireless Metropolitan network, it is the connection of the various Local area network. The main advantage of this Metropolitan network is that it provide high security to the network and the users. But the management of the Metropolitan network will be to tiring and the internet speed will be different at various regions.

What Benefits Will Configuring Vlans Provide To The Current Configuration?
This configuration will hello the higher performance and monitor and it will also improve the reliability and control of all the devices. Now let Aslam about the basic configuration of VLAN in detail.
Here firstly we need to create the VLAN interfaces. Now firstly determine the IP address which we want to assign to the interfaces that are present on the switch.
And in order to route between these VLANs, the VLAN must contain the IP address.
Suppose one packet is received by a switch which should be sent to the VLAN or subnet. Then hear the switch will forward the packet to the destination address based on the information given on the routing table.
Hear the destination interface will transfer the packet to the put or interface to which the destination device is attached to.
After this, we simply need to open a web browser and we need to type the IP address, normally the default IP address of any device will be 192.1 68.0.239, and the default Subnet Mask will be the same as 255.255.255.0.
And we need to enter the login credentials and click on the login button. After ways we simply need to select the IP configuration, after this we need to enable the radio button and hence the routing is enabled.
Now let us know the difference between the static VLAN and the dynamic VLAN. The static VLAN is normally called the port-based VLAN. This static villain mostly has a manual assignment of all the individual ports on a virtual network. Once we assign all the ports, then these are all associated with some of the pre-assigned VLANs.
Now let us take an example in order to understand the concept of static VLAN. Suppose we assign ports like 1,2,3,4 to the VLAN for department 1, the same way we assign 5,6,7 ports to the VLAN from department 2. And in the same way, we assign port 8,9 to another department called department 3.
The static VLAN will not deal with the devices, here when we try to plug one of the devices into port 1, let’s say this device will be on department 1 similarly when we try to plug, the same device into port 9 then this device will become the member of department 3.
But the dynamic VLAN is different from the static VLAN. The dynamic VLAN will be defined on the basis of port location. It is mainly used by the Mac address of a device. All the memberships of VLAN are based on the IP address of the device.
All the dynamic balance will require a server which is called a member policy server, shortly called the VMPS server. The list of Mac addresses will be present along with the Reliance that is associated with it in the server. The size of the actual MAC address is a 48-bit hexadecimal number.
Let’s say a computer with the wheel and 10 is plugged into port one, now this port one will be able to communicate with the server and will save the database table for the membership.

What Additional Information Is Contained In The 12-Bit Extended System Id Of A Bpdu?
The VLAN ID is the additional information that is contained in the 12 standard system ID of bpdu. Today let us learn about the bpdu guard along with the root guard in detail to understand the concept in detail. The bpdu Guard and the root guard are mainly created in order to protect the Threads that occur against the network. It is also mainly used in order to increase the stability of the network.
Now let us learn about the bpdu guard in detail. For this let us take an example, let’s say we have a user that is slightly connected to the access that is present on the local area network. Here, instead, we connect the PC we will connect the switch in order to increase the number of ports that are present in the room. Hens for this purpose we take a switch and then we just plug it. Let’s say this switch is considered as a running spanning tree, it also consists of a lower Bridge ID and the root Bridge on the local area network.
Then the Spanning Tree will be going to enter into the root Bridge process, here, let’s say the new switch will be able to become the root bridge, then we can able to create a sub-optimal performance on your network.
Here we can also able to broke our design, it may not have any traffic closed on the network.
By simply creating the root Bridge it could be very disruptive to the users. If this is added to the network and hence it will become the root bridge and if you remove the switch then one of the original root Bridges becomes the root, similarly another switch will be added to this. Hence we can able to create a root Bridge continuously.
This is considered an interruption to the network. Hence all of these sports will be considered as the changing stage in the network.
Let’s say if you have a user who doesn’t know anything and tries to connect to a hub, Here they simply want to work for this devil plus a bunch of PCs into the hub and this plug will be in plug into many Jacks that are present on the wall.
Hence the users don’t care about what happens in the network. Here they can able to enter the connecting to the two different access with better present on the network. This might create a loop on the network and the two switches that are present on the network, if they try to exchange some of the PDUs, the ports get involved forwards. Therefore we can able to loot the safety of the forward delay Times, this delay can cause a different problem.
Here the bpdu guards can offer some of the solutions, which means when the bpdu port guard is configured it can able to disable simply after receiving the bpdu. Hence if you switch receives a bpdu on the port which is connected to the hub, if the bpdu got is enabled than the port can able to shut down.

Uid 1-500 Are Usually Reserved For What Kind Of Users?
UID 1-500 is usually reserved for system accounts. These system accounts are nothing but the server processes. UID stands for unique positive integer, this UID is normally assigned to the operating system of each user. All the users can be identified by using this unique positive integer.
Mainly, the UID is between 1 to 500 is generally used for the identification of the user. All these user names are normally used as an interface for humans.
All the user IDS will be stored along with the user names and some other specific information in it, such as password files, etc. These files can be read by simply using the command called a cat.
And the other two fields are called UID and Gid. These or default equal to all the users UID. All the new ideas are 32-bit unsigned integers that can able to represent the values from zero. But the values of this 32bit UID are only used up to 65,534.
All these are used in order to maintain compatibility among all the systems that are using the oldest kernels. Which can only able to accommodate the 16 bit UID.
Now let us know the role of this UID, mainly the address of zero will be having a very special role. This is called the root account. Here the usernames can be changed on this account and can also add some of the additional accounts that can I able to create with the same UID.
The other UID 65534, is considered as the commonly reserved ID, this ID is considered as the user with no kind of privileges. Thus called the unprivileged user. The unit positive integer is mainly used for the accessing of the systems remotely by various protocols like file transfer protocol and hypertext transfer protocol.
The Other UID 99 is considered as the special type of system user. These types of users are considered as the administrators, where there is no need for root powers and can able to perform all the administrative tasks. And hence it requires more privileges than the ordinary number of users.
In the Linux distributions, a few of the new ideas will be used for the nonprivileged users 100. Similarly, other distributions like a red hat will behave UID at 500.
There are many differences between all these different distributions hence, the intervention of multiple distributions on a network is required.
You can also able to reserve blogs for the local users from 1000 to 9999. And we also have another block like a remote user. And we also have another block like a remote user. Here is the most important thing is to decide on a scheme. Hence it makes it more convenient in order to search through the system for any suspicious users activity and it is not exactly required order to enter the UID, the use of non-uid will require some of the security problems and hence it will keep unique across all the organizations

What Are Three Primary Benefits Of Using Vlans? (Choose three.)
Now let us discuss the concept of VLAN and its benefits, we also discuss the broadcast domain along with it in detail. The VLAN is considered as the local area network, this VLAN is considered as the collection of all the different devices.
Here, all these devices are present in the same broadcast domains.
Now let us actually know what is actually broadcast domain is, this broadcast the man is normally used in order to describe the combination of devices on a network segment, this network segment can able to reach the other Ethernet broadcast.
Default age we consider all the interfaces in the switch is in the same broadcaster domain. Now let us take an example in order to understand the concept of this in detail. What supposes if you want to create two different types of Lan and broadcast domain, we simply need to buy two different types of LAN switches. These Lan switches or very expensive, hence this is where the VLAN is used mostly.
The VLAN can also be called the virtual LAN, this virtual LAN is considered as the combination of all the network devices, here when we try to create the VLAN, we normally break the large broadcast domains into smaller broadcasts domains. Hence these VLANs are mostly configured on the switches by simply placing it on some of the interfaces into the broadcast domain and in some of the interfaces.
We can spread these VLANs in multiple types of switches, each of these villains will be created by its own subnet or own broadcasts domains. It is nothing but the frames of Broadcast that are present on the networks that are only considered as the switches that are between the ports and that are present within the same VLAN.
And in order to maintain the communication between these VLANs, we simply need a device or let’s say a layer 3 device.
Now let us know some of the benefits of the VLAN. The main advantage of using the VLAN is that we can able to improve the security in a network. And all the groups which have confidential or sensitive data will be separated from the rest of the network, this will help us to decrease the chances of revealing the confidential information.
Now let us take an example in order to understand the concept of VLAN. Let’s say we have three switches, switch 1 switch 2, and switch 3. Now all these switches are connected to each other. And each of these is connected to different computers. Let’s say 1 computer is completely separated from the other computer.
By using this VLAN, they also have cost reduction results from all the expensive networks and upgrades. And it is also the more efficient use of existing bandwidth.
These VLANs will provide better performance. Dividing the network into VLAN will be able to reduce the number of devices that are present in the broadcast domain. Here another benefit is called efficiency, the management of the network will be very easy by using the VLANs.

Which Network Device Can Serve As A Boundary To Divide A Layer 2 Broadcast Domain?
The router network device can serve as the boundary in order to divide a layer learn broadcast domain. Today let us discuss the layer 2 broadcast domain in detail. Now let us understand what actually broadcast demand is.
Normally, the devices can communicate with each other in various ways and one of these ways is the Broadcast message. This Broadcast message will be having a certain number of implications on how the network will perform.
Hence for understanding a broadcast domain, let us know the basic concept of the broadcast domain.
The basic definition of the Broadcast domain is, it is a set of devices that will receive broadcast frames from any other member that is present in the same group. Here, the group of devices, if one of these sources will broadcast a message then every other member of that group can able to receive it and hence this is called as the broadcast domain.
Let’s say we have several broadcast domains that are present. They are multicast and unicast. Let us discuss only the broadcast in detail. Simply a Broadcast message is considered as a device, and as a message that is Central to every other device on the specific group.
Normally we will be having a Mac address that is present on layer 2 of the OSI model and a layer 3 IP address for its Broadcast message. And the frame is considered as a source from one device that is sent to another network, after copying get it is sent to every other device in the broadcast domain.
Now let us take an example in order to understand the concept of Broadcast domains. Let’s say we have a local area network, and we have a Ham that is connected to the two computers and one port on the router and we have a switch that is connected to the different port on the router. And the switch has two computers that are connected to it.
The main thing to know about the broadcast domain is that the routers are the only ones that can able to create the multiple broadcast domains, and hubs, switches, and bridges can able to create only a single broadcast domain. Hence if it receives any broadcast message then it simply forwards it to every connected port.
But the routers are quite different from this. And the switches can be configured by simply using multiple VLANs.In each of the broadcast domains, every device requires to receive the Broadcast message and in order to process it, it can take different loads on each of the different devices. And if you have any large broadcast domain, a single computer can able to source a Broadcast message. Here, we also have the bandwidth that consumes the broadcast domains. We also have some of the smaller broadcast domains in order to preserve some of the resources and the bandwidth of the network.

Which Address Is Required In The Command Syntax Of A Standard Acl?
Source IP address is required in the command Syntax of standard ACL. Today let us discuss the ACL in detail. ACL stands for access control list. It is a private type of network which will heavily be protected by various different network devices. The networking devices are nothing but routers, firewalls, proxy servers, and many more.
The router is mainly used in order to connect different types of networks together. The main primary function of this router is to transfer the packets based on layer 3 of the IP address. The late three is nothing but the network layer of the OSI model. This is considered the most important function of the router.
This access control list will be set up in order to control the traffic in both of the directions mean both in incoming direction and outgoing direction.
Normally the access control list will inform the router in order to permit or deny the traffic according to the following rules Or variables like source IP address, source Subnet Mask, destination IP address, and destination Subnet Mask.
Typically, all the subnet masks are mainly used in order to define different types of segments that are present within the network.
The ACL of the router can able to control the traffic based on the transfer control protocol or user datagram protocol or through the port numbers and many more. Normally, we will be having various reasons in order to use the ACLs. The main goal of using the access control list is to provide the basic level of security in the network.
This access control list is also called the rule-based list that is mainly used by the switches and routers in order to identify the traffic that is based on the features or characteristics of the IP addresses and port numbers. Once we identified this we can able to filter the traffic that is present in this list.
We can able to identify the traffic on the basis of the source and destination addresses and also the port numbers. As we said earlier the main use of this access control list is in order to deny or permit the traffic.
This is nothing but we can able to configure the network address translation and we can able to and we can able to allow or deny the quality of services. Now let us date an example in order to understand this.
Let’s say we have a router that has a configuration of ACL. This is serial will be configured with all the rules that can able to tell which of the traffic is allowed in order to pass through it and which traffic is not allowed to pass through it. Let’s say if you want to hello all the traffic which is destined to send to the server, but in the same way, if you want to block or reject all the traffic. Now this will be possible by using the access control list

Refer To The Exhibit. Which Implementation Of Inter-Vlan Routing Does This Topology Use?
The router on stick implementation of inter VLAN routing will be used. Now let us learn about the inter VLAN Routing in detail. Normally we know that each VLAN will be different and will be isolates the broadcast domain. All the hosts which are present on the separate VLAN I will not able to communicate even if they are connected to the same side of the switch.
But the Communications between all these different VLANs will be used in many different cases. Or simply we can say that we need to find various ways in order to route the traffic through different VLANs. Hence this concept is called inter-VLAN routing.
Now let us know about the different options of inter-VLAN routing. Firstly we can use the traditional approach, for this we need the physical router and we connect these to each VLAN to the different physical router interfaces. Let’s say we have 3 VLANs that are connected to the single switch, they are VLAN 10,vlan20, and VLAN 30. Each of these VLANs has its own physical link that is connected to different physical router interfaces.
Hence, with this type of approach, the router doesn’t need to know about the VLANs. It simply will treat it as a single VLAN. Here, if the VLAN device will send the packet to the VLAN 30 device, then the switch will deliver this packet to the router through the VLAN 10 links.
And the router will forward this packet to the switch through the VLAN 10 device link.
Then, the switch will forward this to the VLAN 30 device. Here, routing and switching can be achieved by this. But this traditional approach will be having some of the limitations as usual. Here, the number of physical interfaces that are present on the router will be very limited and very expensive. Here, we will need every cable that is going from the switch to the router to every single VLAN. This type of method will normally work with two or three VLANs. Even then it is a very challenging process on a large network.
In order to overcome this limitation, we will move to another option. That is called a router on a stick. This router on your stick is a type of setup that consists of a Router and a switch that are connected by using an ethernet link that to be configured as an 802.1 Q trunk. Here the router should understand the concept of VLAN and the concept of IEEE 802.11 q standard.
Here, in the traditional approach when each of the cables that are moving from one switch to the router can be configured as an access link. But with the presence of a route on a stick the inter VLAN routing will be able to configure one of the single links as a trunk.
In a physical manner, we will be having only one interface on the router. But many of the logical sub-interfaces will be created.

Which Product Corresponds To A Layer Of The Cisco Collaboration Architecture?
Network and computer infrastructure corresponds to a layer of the Cisco collaboration architecture. Today let us learn about the network and computer infrastructure and the Cisco collaboration in detail.
Now let us know about the brief introduction to the Cisco collaboration. In order to understand the Cisco collaboration let’s say we break this word into four different categories. They are calling meetings, messaging, and contacting the center. Now let us know how we actually consume all these categories.
In this let us mainly focus on Cisco unified Communications manager which is shortly called CUCM, Cisco Unified Communications manager which is shortly called IMP.
The main use of this Cisco collaboration is, it helps all the enterprises in order to connect and monitor all the devices and secure and automate the operations and we are also able to compute and manage all the data.
Now let us know about the network infrastructure in detail. The network Infrastructures or networks are mainly developed or designed in order to share the information between the several devices. Normally these links can able to communicate through analog or digital signals.
We use various types of methods in order to transmit the signals on telecommunication. Normally there are two types of methods, they are baseband or broadband method.
The baseband method normally refers to the single signal that will be passed through the communication link.
And the broadband has two or more signals that are present on the same link and the transmission of these signals and broadband will be having different frequencies.
At present the networks are managed centrally, the internet network architecture will be having a high-speed Local area network and wide area network.
The architecture consists of clustering of all the devices and we have different types of functions in the network segments like web services and other application services. There are different types of networks that we normally have such as Local area networks, wide area networks, Storage Area Networks, and many more.
All these network types will be used in order to interconnect the computer devices and we use this in order to save the information between the devices, we have a Local area network to maintain a Communication network that can able to interconnect different devices within the Local Network. For example, office, School, etc.
And we have Metropolitan Area Network, which is shortly called a MAN. This Metropolitan area network is called a communication network that can able to connect different devices in Geographic regions. The best example of this Metropolitan is cities.
And we have a wide area network, this wide area network is unable to join various networks and locations across the large location or area. Simply we can call it a Global connection. The best example of this wide area network is the internet.
We have different types of configurations in the network like bus topology star topology mesh topology, ring topology, tree topology. All these are considered as a type of configuration that the network should be used.
