The answer is to follow the incident response plan. This is the correct first step when observing anomalous outbound traffic because the plan provides a structured, pre-approved workflow that ensures proper identification, reporting, and containment without introducing panic or ad-hoc decisions that could destroy evidence or escalate the breach. On the CompTIA SecurityX CAS-004 exam, this question tests your understanding that the incident response plan is the authoritative guide from the very first moment of detection; a common trap is jumping straight to containment or shutting down the server, which can wipe volatile data like active network connections. Remember, the plan is your safety net—always consult it before acting. A useful memory tip is "Plan before you pan," reinforcing that the first step is never technical action, but procedural compliance.
CAS-004 Security Operations Practice Question
This CAS-004 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 security analyst observes anomalous outbound network traffic from a server that normally only performs internal functions. According to the incident response plan, what should the analyst do first?

Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Follow the incident response plan
Option A is correct because the first step in incident response is to follow the established plan to ensure proper handling and minimize damage. Option B is wrong because containment should follow identification and reporting. Option C is wrong because shutting down may destroy evidence. Option D is wrong because ignoring is risky.
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.
✓
Follow the incident response plan
Why this is correct
The incident response plan provides procedures for initial actions, including identification and reporting.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Contain the server by disconnecting it from the network
Why it's wrong here
Containment occurs after the incident has been declared and plan followed.
✗
Immediately shut down the server
Why it's wrong here
Shutting down may lose volatile data and is not first step.
✗
Ignore the traffic as it might be a false positive
Why it's wrong here
Ignoring could lead to undetected breach.

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.

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.

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 practitioner preparing for the CAS-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
