Kubernetes and Cloud Native Associate (KCNA) — Question 174

Which of the following is a valid PromQL query?

Answer options

• A. SELECT * from http_requests_total WHERE job=apiserver
• B. http_requests_total WHERE (job="apiserver")
• C. SELECT * from http_requests_total
• D. http_requests_total(job="apiserver")

Correct answer: D

Explanation

The correct answer is D because it accurately follows the PromQL syntax for querying metrics with specific labels. Options A and C use SQL-like syntax which is not valid in PromQL, while option B incorrectly uses a WHERE clause that is not part of the PromQL query structure.
