This CS0-003 practice question tests your understanding of security operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: cloud audit logs record all API calls made to the cloud control plane.. 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 cloud tenant shows an unusual spike in IAM policy changes, access key creation, and failed console logons from a new country. Which telemetry set gives the strongest evidence for control-plane compromise? In the alert triage phase, Which action gives the analyst the clearest next triage step?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud audit logs for identity, policy, and key-management API calls
Option C is correct because cloud audit logs (e.g., AWS CloudTrail, Azure Activity Log) capture control-plane API calls such as IAM policy changes, key creation, and authentication failures. These logs directly record the identity and resource management actions that indicate a compromise of the cloud management plane, whereas endpoint or network telemetry only reflects data-plane activity and cannot see API-level administrative actions.
Key principle: Cloud audit logs record all API calls made to the cloud control plane.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Endpoint antivirus quarantine reports only
Why it's wrong here
Endpoint reports may be useful later but do not directly explain cloud control-plane changes.
✗
Packet captures from user laptops only
Why it's wrong here
Network captures may not show cloud API intent or identity changes.
✓
Cloud audit logs for identity, policy, and key-management API calls
Why this is correct
Control-plane attacks are best investigated through authoritative audit events that record who changed identity and access configuration.
Related concept
Cloud audit logs record all API calls made to the cloud control plane.
✗
Web server access logs from the public website
Why it's wrong here
Web logs do not prove IAM policy or key-management activity.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse data-plane telemetry (endpoint AV, packet captures) with control-plane telemetry, failing to recognize that only cloud audit logs can capture administrative API calls like IAM policy changes and key creation.
Trap categories for this question
Command / output trap
Network captures may not show cloud API intent or identity changes.
Detailed technical explanation
How to think about this question
Cloud audit logs (e.g., AWS CloudTrail) record every API call to the IAM, KMS, and STS services as JSON objects containing the caller identity, source IP, timestamp, and request parameters. In a real-world scenario, an attacker who steals cloud credentials can create new access keys and modify policies without any endpoint or network telemetry showing the malicious activity, making audit logs the only definitive source for detecting control-plane compromise.
KKey Concepts to Remember
Cloud audit logs record all API calls made to the cloud control plane.
IAM policy changes and key creation are control-plane actions.
Failed console logons indicate attempts to access the control plane.
Cloud audit logs are the authoritative source for control-plane activity.
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
Cloud audit logs record all API calls made to the cloud control plane.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
