CCNA 500+ Interview Questions & Answers PDF Overview

Q.1.What does cat stands for in networking?

 Ans :- Cat stands for “CATEGORY“. Which started from Cat1 (Category1) and now extend up to Cat7 (Category 7). Improved version/category of cable improve the quality of data transmission and make enhancement in bandwidth .provide more stability.

Functions of Routers:

  • Send and receive data on computer networks.
  • Used to create local networks of devices
  • Helps to connect multiple devices to the Internet.
  • Allows users to configure the port as per their requirements in the network.
  • Filter unwanted interference, and carry out the process of data encapsulation and decapsulation.
  • Used to segment network traffic.
  • Prevent network bottlenecks simply by isolating portions of a network.
  • Reduce excessive traffic.

Q.2. What is the purpose of the Data Link?

The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing.

Q.3. What is the key advantage of using switches?

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.

Q.4. When does network congestion occur?

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.

Q.5. What is a Window in networking terms?

A Window refers to the number of segments that are allowed to be sent from source to destination before an acknowledgment is sent back.

Q.6. Does a bridge divide a network into smaller sections?

Not really. What a bridge actually does is to take the large network and filter it, without changing the size of the network.

Q.7. Which LAN switching method is used in CISCO Catalyst 5000?

CISCO Catalyst 5000 uses the Store-and-forward switching method. It stores the entire frame to its buffers and performs a CRC check before deciding whether or not to forward that data frame.

Q.8. What is the role of the LLC sublayer?

The LLC sublayer stands for Logical Link Control. It can provide optional services to an application developer. One option is to provide flow control to the Network layer by using stop/start codes. The LLC can also provide error correction.

Q.9. How does RIP differ from IGRP?

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.

Q.10. What are the different memories used in a CISCO router?

Different memories used in a CISCO router are:

  • NVRAM stores the startup configuration file.
  • DRAM stores the configuration file that is being executed.
  • Flash Memory – stores the Cisco IOS.
