CCNA Routing and Switching Exam Questions and Answers PDF

Are you preparing for the CCNA Routing and Switching Exam? Look no further! In this comprehensive blog post, we have compiled a set of relevant exam questions and provided detailed answers to help you ace your certification.

1. What is the purpose of default routing?

Answer: Default routing is used when a router doesn’t have an explicit route to a destination in its routing table. It allows the router to forward packets to a default gateway or next-hop IP address.

2. What are the advantages of using VLANs?

Answer: VLANs (Virtual Local Area Networks) provide the following benefits:

  • Improved network security by dividing the network into logical segments.
  • Enhanced performance by reducing network traffic.
  • Simplified network management and troubleshooting.

3. How does STP (Spanning Tree Protocol) prevent loops in a redundant network?

Answer: STP uses a tree-like topology to ensure that there is only one active path between any two network devices. It establishes a root bridge and calculates the shortest path from each non-root switch to the root bridge, blocking redundant paths to prevent loops.

4. Explain the difference between static routing and dynamic routing.

Answer: Static routing involves manually configuring routes in a router’s routing table. It is suitable for small networks with a few routers. Dynamic routing, on the other hand, uses routing protocols to automatically exchange routing information between routers. It is more scalable and adaptive to network changes.

5. What is the purpose of Access Control Lists (ACLs) in networking?

Answer: ACLs are used to filter network traffic based on specific criteria, such as source/destination IP addresses, protocols, and ports. They provide security by allowing or denying traffic flow between networks or hosts.
