What is a possible cause of runt Ethernet frames when a switch is being used?
Answer: The malfunctioning of NIC is the possible cause of runt Ethernet frames when the switch is being used. The runt frames size is less than 64 bytes and is considered as the minimum Ethernet frames size which is allowed.it is the type that is due to the NIC malfunctioning or the overdue collision. The misconfiguration of the duplex is the reason for the problem in the connectivity. The extravagant length of the cable causes errors in CRC or an overdue collision.
The runt Ethernet frames are usually less in size and the minimum size is 64 bytes and have poor FCS. In the half-duplex, the frames are almost due to the collision. If the frames happen even the collision is not high or in a full-duplex condition then maybe they are the outcomes of poor software or the NIC.
Moreover, we know that the encapsulated data is known as the Ethernet frames which are defined by the network access layer. The frames begin with the header which has the physical address of the source and destination along with other information. The frames center is the actual data and the end of the frames along with a field is known as the frame check sequence (FCS). the part of the frame is described in the following:
Preamble:
It gives the information about the receiving system which enables the synchronization and is also responsible to start the frames.
SFD:
It can determine that the destination’s physical address initiates with the next byte.
MAC address of destination:
It can identify the receiving system.
MAC address of source:
It can determine the sending system.
Type:
It can identify the protocol type within the frames such as it is either IPv4 or IPv6.

When creating network diagrams, what icon description typically represents a network router?
Answer: During the creation of the network diagram the icon along with a hockey-puck shape has two arrows pointing inward and the other two points outward represent the network router.
The network diagram is the map of the present network which describes the nodes and the connections among them. The network diagram is essential in the process of mapping the elements and the interactions of devices and also determining the different types of the topology.
We can also manually map the network with the help of pencil and paper and the software are useful because they have tools. one famous tool is Aulik which gives strong network topologies which are updated in real-time. The difference between the physical and logical network diagrams is also important to understand.
The network diagrams come in various shapes and sizes but they are categorized in either the physical network diagram or a logical diagram. in the network topology, the point of the focus is the lower layers of the OSI model. The physical layer is layer 1, for the network design the things we can touch, such as cable and equipment but it also has signal properties.it can define the characteristics of the cable which use to carry the signals. When we see at the physical network diagram the devices as firewalls, switches, routers are with the representations of the physical connection.
While the logical layer is layer 2 of the OSI model, the logical diagram is responsible to show the network topologies at the greater level. Some of the logical diagrams have physical attributes it is not essential while some of them do not consider the physical links.

What kind of device can monitor a connection at the Demarc but cannot interpret data?
Answer: smart jack is a device that can monitor a connection at the Demarc point but not be able to interpret the data.
The demarcation is the point toward where one organization interface owns all the facilities related to the communication with other organizations. In the terminology of telephone, it is considered as the interface between customer-premises equipment and the network service equipment.
It is the mark where the public telephone network terminates and the client’s private network of either an organization or business starts. It is the initiation point of the telephone company where the wires connect with the wires of the subscriber of the particular company, and the servers are the representation of the point where the network is public and private.it is also considered as the point where the instruments of a phone from a network service provider and the customer-premises meet. All the Demarc points have the smart jack of R-11 which is not connected with the phone network and with the small telephone cord loops which use the connector for the connection with phone jacks.
The Demarc is considered as the NID (Network interface device), but the scene is quite complicated because NID is used as the demarcation corporate point as well, and the reason is that sometimes there might be a larger distance in between the service provider and the private client-owned networks, such as a Demarc point is present on the lower floor of the building the office on the 9 and 10th floor need to connect the private network to that particular point of Demarc which is below their floor.
For such a situation the wires are installed to extend the point of meeting with the client’s private network to keep it in the customer premises, and the whole process is called the Demarc extension.

Which of the following devices are you likely to find in the MDF? Choose all that apply.
Answer: The devices which are likely to identify in the MDF are routers, switches, and the KVM.
MDF (main distribution frame) ac as the primary hub or the Demarc point which interconnects the private or the public IT and telecommunication lines through any number of IDFs which are moving toward the building to the internal network.
The wire of the office must be connected with the central MDF closet and them with the individual IDF closet, at the end it has to be connected with the workstations. If the company is larger and extends to multiple floors and the MDF is located at the first floor which connects the public lines from the outside, the MDF must connect the line through the IDF on each floor with the internal network.
The common MDF type is the long steel rack which is easy to access from each side. at the form of the rack on the individual side, the termination block is placed in a horizontal form.to run from the vertical places blocks the jumpers located on the shelf and moves them from a steel hoop.
Numerous numbers of the jumpers are held by the MDF and dozens of them are modified each day for decades and they can’t be twisted when an MDF is administered by the professionals. The jumpers are the cable in the form of twisted pairs and each of them is related to the individual telephone lines.
MDF is single-sided which allows the workers to install, remove or make any changes in the jumpers. The jumper system is now modified and becomes automated with the help of automated MDF. In the private system exchanges, the MDF work is similar to the function in the central office but works on a small platform.

Which Command Will Display the Contents of NVRAM?
Answer: To view the contents of NVRAM or to view the configuration file it points to from a CONFIG_FILE environment variable, use the EXEC command for the show startup-config.
NVRAM stands for non-volatile random-access memory it is the memory type that saves the data which is stored without the worry if the power is on or off. The best example of NVRAM is the flash memory used in a jump drive. It’s also found in a monitor, in print cars, and in lots of different gadgets that require the settings to be remembered.
The computer’s RAM is volatile when the computer turns off all the data vanished while the non-volatile and it is used in a server, not with the home computers. NVRAM has various types for different computers. inside the laptop motherboard, the RTC/NVRAM is geared up with a buffer battery which makes use of the CMOS battery that could rate and keep parameters consisting of date and time.
EEPROM is the other type of NVRAM that is used for the BIOS in many systems, the hard drive, and many other storage devices are also non-volatile. FeRAM, Magneto resistive RAM is the NVRAM type which use for various purposes.
NVRAM’s advantages and disadvantages are described in the following:
Pros:
Cons:
- As NVRAM needed the battery then after some time it will need the replacement of the battery.
- As data is written back to flash memory, it shuts down and no longer works.

Which configuration must be in place for the auto-MDIX feature to function on a switch interface?
Answer: The auto-MDIX work for only the Cisco devices at the point when the speed and the duplex of the interfaces are set to auto-detect.
The media-independent interface with the crossover is the port on the desktop, hubs, switches, etc. They are connected through RJ-45 connectors or the twisted pair cable, fiber optics. They are the ethernet interface type and the essential part of the data transfer within the network. MDI port signals are sent toward the ethernet network either the switch or routers, on the other hand, the signals transferred from the switch, MDI port, or routers are reached in the form of crossover on the workstation or the MDI port.
Simply, the outgoing and the incoming signals are reversed and it will remove the need for a twisted pair cable on the MDIX port.in most of the devices, the MDI and MDIX ports are present while in the computer only the MDI port exists. With the help of the Ethernet cable, the latter is connected with the router, and the crossover twisted-pair cable helps in the establishment of the MDI to MDIX connection. To prevent the cable an MDI port must be present in a switch or router. Auto-MDIX feature developed to keep the complication in the MDI-MDIX port. as the name suggests auto-MDIX automatically detects the type of port. The feature helps in the identification of the simple or the crossover cable is needed according to the configuration of the MDI and MDIX.in the case of the exact port linking the use of the cable doesn’t matter.

A User Is Complaining of Delays When Using the Network. What Would You Do?
Answer: If the hub is in use, then to prevent the delay use the switches which will lessen the late if many users are accessing the network at a time as files copy, etc. The antivirus and the firewalls are the reason for the delay remove them and check if the improvement occurs after the install an AV which will also cause delay but is better than it. The malware is also the reason for the delay in the network, for this you need to reinstall the operating system. The delay in the internet connection is improved with greater bandwidth.
Network might have problems occurs because none of the things is 100% guaranteed. Some of the network problems are listed in the following:
Use of high bandwidth:
Bandwidth is defined as the amount of transmitted data in a given time. The network capacity to transfer the data over the internet in a period.it is the misconnect that bandwidth is the speed of the internet but it is the amount of the data which is transferred in a limited time and measured in megabits per second (Mbps). sing the high bandwidth cause the network congestion. it will also use the bandwidth of the other parts of the network, and the slow internet is the sign of it.
Hardware issue:
A hardware problem might cause the issue in the network. the troubleshooting refers to the problem related to complicated parts but sometimes it is due to the easy parts which are Infront of our eyes. The hardware issue is the cable damage or the network equipment, or network properly. Sometimes the network failure is caused due to malfunctioned wires.it will also affect the LAN infrastructure, if the fiber optic is damaged it will lessen the data amount which is going through without any loss of frames. The network performing software helps in the detection of the defective cables.

Which of the following is true for asymmetric cryptography?
Answer: In asymmetric cryptography, the private key is on the receiver side while the public key is announced in the public so anyone can use it.
Asymmetric cryptography is also referred to as public-key cryptography which contains the pair of the key who are also related to each other, one is referred to as the public key while the other is the private key, that can encrypt and decrypt the data and also keep it safe from the unknown or unauthorized access.
In cryptography, the public key is the one that is accessible to any person which is used to encrypt the message but the message is decrypted by the person who has the private key, which is referred to as the secret key and only one person has an access to it. if you want to send the message in the encrypted form then you have to pull the public key from the directory of the particular person that can encrypt the message first before sending it. The receiver side can decrypt it with the help of the private key.
If the sender tries to encrypt the message through the private key then it is only decrypted with the use of the sender’s public key, by verifying the sender. The cryptography process is automatic and there is no need for the end-user to encrypt the data manually. Different kinds of protocols based on this asymmetric cryptography such as TLS (transport layer protocol), SSL (secure socket layer protocol) can make HTTPS happen. The software also uses cryptography to protect the insecure network by developing a secure connection.

Which of the following best describes the purpose of an ISP?
Answer: The sole purpose of the ISP is to give free access to the internet is an organization that gives internet access, it is referred to as “the provider”.
ISP (internet service provider) is developed for the purpose to provide access to the internet. The data are transferred with the help of multiple technologies such as the dial-up, DSL, cable system, wireless, etc. It can give the service to the customers to communicate to other person located in different places with internet email accounts, normally various email addresses at customer choice. Some of the other services like the telephone TV personal sites, home pages are also provided by ISP.to each ISP the services and their combination are different.
In today’s world, mobile companies or cable are the ISP that offer internet subscriptions including TV and mobile packages. Another term for ISP is the internet access provider.
To connect the devices with internet, networking, routing the instruments are needed and most of the users are not able to have all these things that’s why ISP lend them access to the network which allow them to develop the connection with the internet, manage the infrastructure and also manage the domain names. Some of the internet service providers provide free access but for a limited time with limited speed.
For the government, research, labs schools, and universities the closed network is developed, this kind of internet access is for the faculty and employees but ISP gives access to them in their homes as well’s is the whole process, individuals pay to ISPs for internet access, and ISP at the access points are interconnected, in turn, they will pay to other ISP which are larger than them and so on.
