It may be a computer, printer or any other device that can send and receive the data over any network. What will be the function of the application layer in the networking?
- Answer: The application layer is used to support the communication components of application and it will provide the network services to the application process that will span beyond the specifications of the OSI reference model. Tell about basefx. State the advantages of using switches. Answer: When the switch will receive a signal, it will create a frame out of bits received from that signal. In this process, it will access and read the destination address and after that, it will forward the frame to the right port. It is considered as the perfect way for data transmission instead of the distribution of the data on all the ports. What do you mean by a window in terms of networking? Answer: In networking, a window is used for the number of segments that will be sent from the source to destination before sending back an acknowledgment.
Basic CCNA Networking Interview Questions & Answers [UPDATED 2021]
Is a bridge used to divide the network into the smaller sections? Answer: No, a bridge actually works to take the large network and filter it. It will not change the size of the network.

In this example, The rest are valid host IDs on subnet You need to have 20 subnets with 5 hosts per subnet. What subnet mask will you use? If you borrowed only 4 bits you could only have 14 subnets. The formula is 2 to the power of n To get 20 subnets, you would need to borrow 5 bits so the subnet mask would be 48 You are given the IP address of What is the network address in binary? The rest is , which is The first octet rule states that the class of an address can be determined by the numerical value of the first octet. Class A addresses include Class A addresses include 1. Class B addresses include Class C addresses include Class D addresses include- When you are using a Cisco Router, the User mode is being used for the regular task. For instance, it is used to connect to remote devices, to see system information; it is also used to check the status of the router. On a different note, the Privileged mode includes all options that are there for the user mode and more. This mode can also be used for making any changes in the configurations on the router including debugging and making various tests. In full duplex, both the devices, the one that is transmitting and the other that is receiving at the same time, can communicate together.
- This means that both the devices, the one transmitting and the other receiving, can receive and transmit at the same time. On the other hand, in case of half duplex, a device cannot transmit while it is receiving and vice versa. Standard Access List can filter only the source or the destination IP address. On the other hand, an extended access list uses the source and destination IP address, socket, protocol and port while filtering a network. In a collision domain, the chances of data colliding are huge. Just as in Hub, if more than one sends traffic at the same instant, data will collide mid-way, and no one will receive data. We use straight cable to connect two different layer devices like router-pc, router switch as well as the switch pc while the cross cable is used for connecting two same layer devices like a switch with a switch, a router with router and pc with pc. Color-coding for both the cables is different. However, if the color-coding on the end of the cable is same, then it is a straight cable.
- Multicasting, on the other hand, means a one-to-many chain of communication. In multicasting, however, there must be at least one device that is not receiving the file. Broadcasting, on the other hand, means one-to-all communication. In case of broadcasting, every device receives packets. Lastly, anycast is one-to-nearest communication. It works on IPv6. Data encapsulation is the process of adding header and trailer information in the data. Whenever data is being passed from one layer to another, the layers add some extra information to the data. This is known as a header. The next layer processes the data and adds its own header. As the data further moves on through layers, the same process continues until the data is placed on the physical media.
- This entire process is called encapsulation. In contradiction to this, removing the trailer information and the header from the data is called data decapsulation. When you have to route globally over the internet, public IP addresses are used. They are provided to different websites and companies for access over the Internet. Once connected to the internet, they become unique worldwide. On the other hand, private IP addresses are for personal and local use. You cannot route them over the internet.
- Private IP addresses can be the same in different organizations. Got a Questions?

Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices. The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing. When a switch receives a signal, it creates a frame out of the bits that were from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port. This is a very efficient means of data transmission, instead of broadcasting it on all ports. Network congestion occurs when too many users are trying to use the same bandwidth. This is especially true in big networks that do not resort to network segmentation. A Window refers to the number of segments that are allowed to be sent from source to destination before an acknowledgment is sent back.- Not really. What a bridge actually does is to take the large network and filter it, without changing the size of the network. It stores the entire frame to its buffers and performs a CRC check before deciding whether or not to forward that data frame. It can provide optional services to an application developer. The LLC can also provide error correction. RIP relies on the number of hops in order to determine the best route to a network. On the other hand, IGRP takes consideration many factors before it decides the best route to take, such as bandwidth, reliability, MTU and hop count.

BootP is a protocol that is used to boot diskless workstations that are connected to the network. It is short for Boot Program. The Application Layer supports the communication components of an application and provides network services to application processes that span beyond the OSI reference model specifications. It also synchronizes applications on the server and client. On the other hand, privileged mode includes all options that are available for User Mode, plus more. You can use this mode in order to make configurations on the router, including making tests and debugging. This is Ethernet that makes use of fiber optic cable as the main transmission medium.- The stands for Mbps, which is the data speed. In full-duplex, both the transmitting device and the receiving device can communicate simultaneously, that is, both can be transmitting and receiving at the same time. In the case of half-duplex, a device cannot receive while it is transmitting, and vice versa. It refers to the maximum packet size that can be sent out onto the data line without the need to fragment it. In Cut-Through LAN switching, as soon as the router receives the data frame, it will immediately send it out again and forward it to the next network segment after reading the destination address. Latency is the amount of time delay that measures the point from which a network device receives a data frame to the time it sends it out again towards another network segment. The maximum limit is 15 hop counts.

Anything higher than 15 indicates that the network is considered unreachable. Frame Relay is a WAN protocol that provides connection-oriented communication by creating and maintaining virtual circuits. It has a high-performance rating and operates at the Data Link and Physical Layers. Each interface that is used in the IPX network is then configured with a network number and encapsulation method. There are two types of IPX access lists 1. Standard Access List can only filter the source or destination IP address. An Extended Access List uses the source and destination IP addresses, port, socket, and protocol when filtering a network. VLANs allow the creation of collision domains by groups other than just physical location. Using VLANs, it is possible to establish networks by different means, such as by function, type of hardware, protocol, among others. This is a big advantage when compared to conventional LANs wherein collision domains are always tied to physical location.Basic CCNA Networking Interview Questions & Answers [UPDATED ]
Subnetting is the process of creating smaller networks from a big parent network. As a part of a network, each subnet is assigned some additional parameters or identifier to indicate its subnet number. A layered network offers many advantages. It allows administrators to make changes in one layer without the need to make changes in the other layers. Specialization is encouraged, allowing the network industry to make progress faster. A layered model also lets administrators troubleshoot problems more efficiently. It's because UDP is unreliable and unsequenced. It is not capable of establishing virtual circuits and acknowledgments. Presentation layer supports many standards, which ensures that data is presented correctly.- It uses triggered updates to reset the hold-down timer. Packets are the results of data encapsulation. These are data that have been wrapped under the different protocols of the OSI layers. Packets are also referred to as datagrams. Segments are sections of a data stream that comes from the upper OSI layers and ready for transmission towards the network. Segments are the logic units at the Transport Layer. Route Poisoning is the process of inserting a table entry of 16 to a route, making it unreachable. This technique is used in order to prevent problems caused by inconsistent updates on a route.
- The best way to go about this is to use the equation minus the subnet mask. The hosts that are considered valid are those that can be found between the subnets. DLCI, or Data Link Connection Identifiers, are normally assigned by a frame relay service provider in order to uniquely identify each virtual circuit that exists on the network. From a data transmitter's point of reference, data from the end user is converted to segments.
- Segments are then passed on to the other layers and converted into packets or datagrams. These packets are then converted into frames before passing on to the network interface. Finally, frames are converted to bits prior to actual data transmission. There are actually five types of passwords that can be used. These enable secret, virtual terminal, console, and auxiliary. For a network administration, segmenting a network would help ease network traffic and ensures that high bandwidth is made available at all times for all users. This translates to better performance, especially for a growing network. The hostname and the Interfaces. The hostname is the name of your router. The Interfaces are fixed configurations that refer to the router ports. Physical Topology is the actual layout of the network medium.
- This may happen when the hold-down timer has already expired, or when the router received a processing task that incidentally was proportional to the number of links in the internetwork.
