CompTIA Network+ (N10-008) — Question 248

A network administrator would like to enable NetFlow on a Layer 3 switch but is concerned about how the feature may impact the switch. Which of the following metrics should the administrator graph using SNMP to BEST measure the feature's impact?

Answer options

• A. CPU usage
• B. Temperature
• C. Electrical consumption
• D. Bandwidth usage

Correct answer: A

Explanation

Monitoring CPU usage is critical when enabling NetFlow because the feature can increase processing load on the switch, impacting performance. The other options, such as temperature, electrical consumption, and bandwidth usage, do not directly reflect the performance hit that NetFlow may have on the switch's processing capabilities.
