CompTIA Exam XK0-005 Topic 3 Question 44 Discussion

Actual exam question for CompTIA's XK0-005 exam
Question #: 44
Topic #: 3
[All XK0-005 Questions]

Users are reporting that a Linux server is responding slowly. A systems administrator troubleshooting the server issue sees the following iostat output, with %iowait at 50.38. Which of the following is most likely the issue?

Show Suggested Answer Hide Answer
Suggested Answer: A

The %iowait value represents the percentage of time the CPU is waiting for I/O operations to complete. A high %iowait value suggests the system is bottlenecked by disk I/O, which could lead to slow response times. Addressing disk I/O bottlenecks would improve performance.

You know what they say, 'if the iowait's high, it's time to say goodbye.' Gotta be A, my dudes.

I bet the admin is wondering if they accidentally ordered the 'Slow Server 3000' model. Option A is the way to go here.

Ah, the good old 'waiting on I/O' problem. Classic Linux server issue. Definitely option A.

Hmm, with 50.38% iowait, it's gotta be A. The CPU is just twiddling its thumbs waiting for I/O to catch up.

I'll start investigating ways to improve the I/O performance on the server.

That sounds like a good plan. Let's look into that.

Should we try to optimize the I/O operations to reduce the wait time?

I agree, the CPU is definitely waiting around for I/O operations.

I agree with Kina, %iowait at 50.38 indicates CPU is waiting for I/O.

I think the issue is that the CPU is mostly waiting for I/O operations.
