CompTIA Security+ (SY0-501) — Question 651

A technician is auditing network security by connecting a laptop to open hardwired jacks within the facility to verify they cannot connect. Which of the following is being tested?

Answer options

• A. Layer 3 routing
• B. Port security
• C. Secure IMAP
• D. S/MIME

Correct answer: B

Explanation

The correct answer is B, Port security, as it involves restricting access to the network through specific ports to prevent unauthorized connections. Layer 3 routing pertains to the routing of data packets and does not relate to physical port access. Secure IMAP and S/MIME are protocols for securing email communications, which are not relevant to testing physical network security measures.
