- A
Key versions are immutable once created.
Key material cannot be changed; you create new versions for rotation.
- B
Key versions can be rotated automatically without creating a new version.
Why wrong: Rotation creates a new version.
- C
The destruction of a key version is immediate upon request.
Why wrong: There is a 24-hour grace period by default.
- D
You can disable a key version to prevent its use.
Disabling a version stops it from being used for cryptographic operations.
- E
Each key version can have a different purpose.
Why wrong: All versions of a key share the same purpose.

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
✓
Key versions are immutable once created.
Key versions in Cloud KMS are immutable and each has its own key material. You can enable or disable versions for rotation. A key has multiple versions; rotation creates new versions. The state can be ENABLED, DISABLED, DESTROYED, etc. The grace period applies to destruction scheduling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
