CompTIA Network+ (N10-009) — Question 54

A network security administrator needs to monitor the contents of data sent between a secure network and the rest of the company. Which of the following monitoring methods will accomplish this task?

Answer options

• A. Port mirroring
• B. Flow data
• C. Syslog entries
• D. SNMP traps

Correct answer: A

Explanation

Port mirroring is the correct choice because it allows the administrator to capture and analyze the data traffic going in and out of specific ports on a switch. The other options, such as Flow data, Syslog entries, and SNMP traps, do not provide the same level of detailed visibility into the actual contents of the data being transmitted.
