DevOps Tools Engineer (LPIC-OT 701) — Question 21

Which of the following tasks can Logstash fulfill without using other components of the Elastic Stack? (Choose three.)

Answer options

• A. Receive log data from remote systems.
• B. Store log data persistently.
• C. Aggregate log data over a period of time.
• D. Process log data to extract information.
• E. Forward log data to other services.

Correct answer: C, D, E

Explanation

Logstash can process log data to extract information, aggregate it over time, and forward it to other services, making options C, D, and E correct. However, it cannot store log data persistently on its own, which makes option B incorrect, and while it can receive log data, that function typically involves integration with other components, thus making option A incorrect.
