CCNA Security 210-260 Exam Questions and Answers

Are you preparing for the CCNA Security 210-260 exam? Look no further! In this blog post, we will provide you with a comprehensive set of carefully crafted questions and their corresponding answers to help you ace your exam.

Question 1:

What are the four primary functions provided by a firewall in a network security infrastructure?

Answer: The four primary functions provided by a firewall are:

  1. Packet filtering: Examining packets based on specific criteria and making decisions to accept or reject them.
  2. Stateful packet inspection: Monitoring and keeping track of the state of network connections and filtering packets based on their state.
  3. Application-level gateway: Providing proxy services for specific applications, allowing granular control over application traffic.
  4. Virtual private network (VPN): Allowing secure remote access to a private network over the internet.

Question 2:

What is the purpose of 802.1X authentication? Explain the three components involved in 802.1X authentication.

Answer: The purpose of 802.1X authentication is to provide authentication and access control to network resources. The three components involved are:

  1. Supplicant: The client device requesting access to the network.
  2. Authenticator: The network access device (e.g., switch) acting as the intermediary between the supplicant and the authentication server.
  3. Authentication Server: The server responsible for authenticating the supplicant’s credentials and granting or denying access to the network.

As the supplicant attempts to connect to the network, the authenticator forwards the authentication request to the authentication server, which verifies the supplicant’s identity and instructs the authenticator to allow or deny access.

Question 10:

What is the difference between symmetric encryption and asymmetric encryption?

Answer: The main difference between symmetric and asymmetric encryption is:

  • Symmetric encryption uses a single key for both encryption and decryption, whereas asymmetric encryption uses a key pair consisting of a public key for encryption and a private key for decryption.
  • Symmetric encryption is generally faster than asymmetric encryption but requires secure key distribution, while asymmetric encryption eliminates the need for key distribution but is relatively slower.

With these questions and answers, you now have a valuable resource for your CCNA Security 210-260 exam preparation. Remember to thoroughly understand the concepts and practice implementing them in a lab environment for better comprehension.

Happy studying and best of luck in your exam!
