What option in the client configuration file would tell OpenVPN to use a dynamic source port when making a connection to a peer?
Answer

Suggested Answer

The suggested answer is D.

To tell OpenVPN to use a dynamic source port when making a connection to a peer, you should use the 'nobind' option in the client configuration file. This directive instructs OpenVPN not to bind to a specific local port, allowing the operating system to choose an available port dynamically.

Question 8 of 120
Which of the following sshd configuration should be set to no in order to fully disable password based logins? (Choose two.)
Answer

Suggested Answer

The suggested answer is B, E.

To fully disable password-based logins in the sshd configuration file, you should set both `PasswordAuthentication` and `ChallengeResponseAuthentication` to 'no'. `PasswordAuthentication` directly controls whether password authentication is allowed, while `ChallengeResponseAuthentication` controls whether challenge-response authentication methods (often involving passwords) are permitted. Setting these two options to 'no' ensures that all password-based methods of authentication are disabled.

Question 9 of 120
When the default policy for the netfilter INPUT chain is set to DROP, why should a rule allowing traffic to localhost exist?
Answer

Suggested Answer

The suggested answer is C.

When the default policy for the netfilter INPUT chain is set to DROP, allowing traffic to localhost is essential because some applications use the localhost interface to communicate with other applications. Without this rule, inter-application communication on the same machine that relies on the localhost might be disrupted, causing various issues in operation and functionality.
