CS0-003 24/7 SOC operations Practice Question
During a post-incident review, the team finds that the detection was delayed by 4 hours because the SIEM rule had a low priority and was not monitored after hours. Which improvement is most effective?
⚠ Common exam trap
Candidates may assume that increasing the priority of a rule or adding automation will solve delays, but the core issue is the lack of after-hours monitoring, which only 24/7 SOC coverage addresses.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement 24/7 SOC operations
Implementing 24/7 SOC coverage directly addresses the root cause of the detection delay: the lack of after-hours monitoring. Increasing rule priority (A) does not ensure monitoring outside business hours. Adding automated response actions (B) may speed up response but does not solve the detection gap. Including the rule in a watchlist (C) focuses visibility but still relies on human review, which is absent after hours.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the priority of the rule
Why it's wrong here
Raising the rule's priority changes its severity ranking but does not create after-hours monitoring, so the alert still sits unseen. It tempts because priority feels like it drives attention, yet the gap is staffing coverage, not the rule's severity label.
- ✗
Add automated response actions to the rule
Why it's wrong here
Automated response actions execute after a rule fires; they do not shorten the four-hour gap caused by the rule being unmonitored after hours. It tempts because automation reduces response time generally, but the stem's failure is detection visibility, not remediation speed.
- ✗
Include the rule in a watchlist
Why it's wrong here
A watchlist is a lookup list of entities used to enrich or match events; it does not trigger notifications or provide after-hours coverage. It tempts because watchlists sound like heightened monitoring, but they only correlate indicators, they do not alert anyone.
- ✓
Implement 24/7 SOC operations
Why this is correct
Ensures that alerts are monitored around the clock.
