CV0-004 Centralized logging Practice Question
A cloud administrator needs to centralize logs from multiple cloud provider accounts and on-premises servers for security analysis. Which approach should be used?
⚠ Common exam trap
CV0-004 often tests whether candidates confuse local log storage or configuration compliance with true centralized log aggregation — the trap is picking an option that sounds like it collects logs but actually stores them locally or does not cover on-premises sources.

Correct answer & explanation
✓
Configure each account's API activity logging to deliver logs to a central storage bucket, and use a log collection agent on on-premises servers to send logs to a central log service
The correct approach is to configure each cloud account's API activity logging (e.g., AWS CloudTrail, Azure Activity Log, GCP Audit Logs) to deliver logs to a central storage bucket, and use a log collection agent on on-premises servers to forward logs to a central log service. This centralizes logs from both cloud and on-premises sources for unified security analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a serverless function that copies logs from each account to a central storage bucket in a management account
Why it's wrong here
While possible, this is less efficient than native CloudTrail delivery and agent-based logging.
- ✗
Enable virtual network flow logs in each account and store them locally
Why it's wrong here
VPC Flow Logs are for network traffic, not all logs; storing locally does not centralize.
- ✗
Use configuration compliance rules to aggregate logs into a single account
Why it's wrong here
AWS Config is for resource configuration, not log aggregation.
- ✓
Configure each account's API activity logging to deliver logs to a central storage bucket, and use a log collection agent on on-premises servers to send logs to a central log service
Why this is correct
Delivering each account's API activity logs to a central storage bucket, plus a collection agent forwarding on-premises server logs to a central log service, unifies cloud and on-premises sources. This hybrid aggregation satisfies the requirement to centralise logs across multiple accounts and on-premises servers for security analysis.
