DVA-C02 Security Practice Question
Network Topology
Refer to the exhibit. A developer ran the above commands to inspect a KMS key. What can be determined about this key?
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
✓
The key is a customer managed key.
The KeyManager field shows 'CUSTOMER', indicating it is a customer managed key. Option A is incorrect because KeyState is 'Enabled', so the key is not disabled. Option B is incorrect because MultiRegion is false, so the key is not multi-region. Option C is incorrect because the key is customer managed, not AWS managed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The key is disabled.
Why it's wrong here
A disabled key reports KeyState as Disabled; the exhibit shows an Enabled state, so this is contradicted by the output. It is tempting because disabling is a common way to halt decryption, but the describe-key response would explicitly state KeyState: Disabled.
- ✗
The key can be used in multiple AWS regions.
Why it's wrong here
This is wrong because the MultiRegion field in the output is false, which means the key is a single-region KMS key and cannot be used by replica keys in other AWS regions; multi-region support requires MultiRegion to be true.
- ✗
The key is an AWS managed key.
Why it's wrong here
The output reports KeyManager as CUSTOMER rather than AWS, so the key was created and is fully controlled by the account holder, ruling out this being an AWS managed key (which would show KeyManager: AWS and typically an aws/ alias).
- ✓
The key is a customer managed key.
Why this is correct
The KeyManager field explicitly reads CUSTOMER, which is the definitive indicator that this key was created directly by the account owner and is a customer managed key, giving the account full control over its policy, rotation, and lifecycle.
