CCNA Routing and Switching Exam Questions and Answers 2017

Are you preparing for the CCNA Routing and Switching exam? Look no further! In this blog post, we have compiled a comprehensive collection of exam questions and answers from the 2017 CCNA exam to help you ace your upcoming test. Let’s dive right in!

1. Question:

What is the purpose of the Address Resolution Protocol (ARP)?

Answer:

The Address Resolution Protocol is used to map an IP address to a physical (MAC) address on a local network. It helps devices communicate by enabling them to find each other’s hardware addresses based on the known IP addresses.

2. Question:

What are the primary functions of a router?

Answer:

The main functions of a router include:

  • Forwarding data packets between different networks or subnets.
  • Examining the destination IP address in each packet and determining the best path for forwarding.
  • Maintaining a routing table to keep track of network topology and available routes.
  • Implementing network security measures, such as access control lists (ACLs) and firewalls.

3. Question:

What is the purpose of the Spanning Tree Protocol (STP) in a switching network?

Answer:

The Spanning Tree Protocol prevents loops in a switching network. It identifies redundant paths and blocks them, ensuring a loop-free topology. By doing so, STP helps to prevent broadcast storms and improve network efficiency and reliability.

4. Question:

What is the significance of a default gateway in TCP/IP networking?

Answer:

The default gateway is the IP address of the router that connects a local network to other networks or the internet. It serves as the exit point for traffic that does not have a specific route in the local routing table. Without a default gateway, devices would not be able to communicate with external networks.

5. Question:

Explain the purpose of subnetting in IP networking.

Answer:

Subnetting allows for the division of a single large network into smaller subnetworks. It helps in efficient address allocation, reduces network congestion, and enhances network performance. Subnetting also improves security by segregating devices into different logical networks.

These are just a few examples of the CCNA Routing and Switching exam questions and answers from 2017. For more comprehensive exam preparation, we recommend consulting official study resources and practice exams. Good luck with your CCNA certification journey!
