Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Because cloud instances are ephemeral and local logs would be lost if instances terminate
Cloud instances are ephemeral; if an instance terminates, logs stored locally are lost. Centralized logging ensures logs persist independently of instance lifecycle. Option A is incorrect because regulatory compliance may be a secondary benefit, but the primary driver here is the ephemeral nature of instances, not compliance. Option B is incorrect while reducing storage costs might be a benefit, the main reason for centralization is to prevent data loss, not cost savings. Option D is incorrect encryption is a security feature but not the fundamental reason for moving to centralized logging; the key issue is instance ephemerality.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To meet regulatory compliance requirements for log retention
Why it's wrong here
Compliance is a reason but not the most important in this context.
- ✗
To reduce storage costs by using object storage for logs
Why it's wrong here
Cost reduction is a benefit but not the primary reason for change.
- ✓
Because cloud instances are ephemeral and local logs would be lost if instances terminate
Why this is correct
Cloud instances can terminate, so logs must be sent off-instance.
- ✗
To encrypt log data at rest and in transit
Why it's wrong here
Encryption can be done locally; centralization is not required for encryption.
