CompTIA Security+ (SY0-601) — Question 165

A network administrator has been alerted that web pages are experiencing long load times. After determining it is not a routing or DNS issue, the administrator logs in to the router, runs a command, and receives the following output:

CPU 0 percent busy, from 300 sec ago
1 sec ave: 99 percent busy
5 sec ave: 97 percent busy
1 min ave: 83 percent busy

Which of the following is the router experiencing?

Answer options

• A. DDoS attack
• B. Memory leak
• C. Buffer overflow
• D. Resource exhaustion

Correct answer: D

Explanation

The router is experiencing resource exhaustion, as indicated by the high average CPU usage over the last second, five seconds, and minute. This suggests that the router is overwhelmed and unable to handle the current load effectively. The other options, while they can cause performance issues, do not directly explain the consistent high CPU usage shown in the output.
