CompTIA Security+ (SY0-701) — Question 394

A network administrator wants to ensure that network traffic is highly secure while in transit.

Which of the following actions best describes the actions the network administrator should take?

Answer options

• A. Ensure that NAC is enforced on all network segments, and confirm that firewalls have updated policies to block unauthorized traffic.
• B. Ensure only TLS and other encrypted protocols are selected for use on the network, and only permit authorized traffic via secure protocols.
• C. Configure the perimeter IPS to block inbound HTTPS directory traversal traffic, and verify that signatures are updated on a daily basis.
• D. Ensure the EDR software monitors for unauthorized applications that could be used by threat actors, and configure alerts for the security team.

Correct answer: B

Explanation

The correct answer is B because using TLS and other encrypted protocols ensures that data is protected during transit, preventing eavesdropping and tampering. Option A focuses on network access control and unauthorized traffic blocking, which does not directly secure the data in transit. Option C addresses intrusion prevention but not the encryption of data, while Option D pertains to monitoring applications rather than securing network traffic specifically.
