This CS0-003 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 SOC wants a SOAR playbook for suspected phishing that reduces analyst workload but avoids destructive action before confirmation. Which actions are appropriate for the first automated phase? In the alert triage phase, Which action gives the analyst the clearest next triage step?
Clue words in this question
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
✓
Enrich URLs, detonate attachments in a sandbox, and collect mailbox search counts
Option B is correct because it describes non-destructive, automated enrichment actions that gather evidence (URL reputation, sandbox analysis, mailbox search counts) without altering systems. This aligns with SOAR best practices for the initial triage phase, where the goal is to reduce analyst workload by providing contextual data while avoiding destructive actions until confirmation of a true positive.
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.
✗
Disable the reporting user's account immediately
Why it's wrong here
The reporter may not be compromised; disabling the account could be unnecessary.
✓
Enrich URLs, detonate attachments in a sandbox, and collect mailbox search counts
Why this is correct
Early automation should gather context and evidence while keeping analysts in control of disruptive actions.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Close all similar alerts as duplicates
Why it's wrong here
Similarity does not prove benign status or complete containment.
✗
Automatically delete all messages from the sender across all mailboxes
Why it's wrong here
Deletion can be appropriate after validation, but automatic destructive action is risky at the first phase.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between automated enrichment (safe, reversible) and automated response (potentially destructive), tricking candidates into choosing immediate containment actions like account disablement before confirmation.

Detailed technical explanation
How to think about this question
In SOAR playbooks, enrichment actions like URL scanning via VirusTotal or sandbox detonation using Cuckoo or FireEye execute in isolated environments to extract IOCs without impacting production. Mailbox search counts via Microsoft Graph API or EWS help identify phishing campaign scope by counting occurrences of the reported email across users, enabling prioritization without deletion or quarantine. This phase typically runs within seconds to minutes, feeding a dynamic case management system for analyst review.
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.
TExam Day Tips
→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
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
