The answer is implementing automated playbooks for low-severity alerts to perform initial investigation and closure if benign. This strategy directly reduces SOC alert fatigue by offloading the repetitive, high-volume triage of low-severity events from Tier 1 analysts, allowing them to focus their expertise on confirmed incidents and true positives. On the ISC2 Certified in Cybersecurity CC exam, this scenario tests your understanding of the tiered incident response model and the principle of using automation to optimize resource allocation—a common trap is choosing to hire more analysts, which treats the symptom rather than the root cause of noise. Remember the memory tip: “Automate the noise, escalate the voice”—automation handles the low-severity chatter so human analysts can hear the critical signals.
ISC2 CC Security Operations Practice Question
This CC practice question tests your understanding of security operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A large organization has implemented a Security Operations Center (SOC) with a tiered incident response model. Tier 1 analysts triage alerts and escalate confirmed incidents to Tier 2 for deeper analysis. Recently, the SOC has been overwhelmed by a high volume of low-severity alerts from endpoint detection and response (EDR) tools, causing delays in handling true positive incidents. The SOC manager wants to reduce alert fatigue without missing critical threats. Which of the following strategies would be MOST effective?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement automated playbooks for low-severity alerts to perform initial investigation and closure if benign.
Option B is correct because automating playbooks for low-severity alerts reduces the workload on analysts and allows them to focus on high-severity alerts. Option A is expensive and does not address the root cause. Option C could miss important indicators that might escalate. Option D would overload Tier 2 and worsen the bottleneck.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Require Tier 2 analysts to review all alerts before Tier 1.
Why it's wrong here
Creates a bottleneck and increases response time for all alerts.
✗
Increase the number of Tier 1 analysts to handle the volume.
Why it's wrong here
Increases cost without reducing alert volume; may not be sustainable.
✓
Implement automated playbooks for low-severity alerts to perform initial investigation and closure if benign.
Why this is correct
Reduces manual triage and allows analysts to focus on critical threats.

✗
Disable all low-severity alert rules in the EDR.
Why it's wrong here
Risks missing threats that manifest as low-severity alerts before escalation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
