This SOA-C02 practice question tests your understanding of security and compliance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
Refer to the exhibit. A SysOps administrator runs the commands shown. Which key(s) have automatic key rotation enabled?
Only the first key
KeyRotationEnabled is true for the first key.
Only the second key
Why wrong: KeyRotationEnabled is false for the second key.
Neither key
Why wrong: The first key has rotation enabled.
Both keys
Why wrong: The second key does not have rotation enabled.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Only the first key
The first key has automatic key rotation enabled because the `EnableKeyRotation` API call was made specifically for that key (key ID `1234abcd-12ab-34cd-56ef-1234567890ab`). AWS KMS automatic key rotation is a per-key setting that must be explicitly enabled; it is not enabled by default. The second key (key ID `0987dcba-09fe-87dc-65ba-0987654321fe`) was not subjected to any rotation-enabling command, so it retains the default disabled state.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Only the first key
Why this is correct
KeyRotationEnabled is true for the first key.
Related concept
Read the scenario before looking for a memorised answer.
Only the second key
Why it's wrong here
KeyRotationEnabled is false for the second key.
Neither key
Why it's wrong here
The first key has rotation enabled.
Both keys
Why it's wrong here
The second key does not have rotation enabled.
Common exam traps
The trap here is that candidates assume automatic key rotation is enabled by default for all KMS keys, but in reality it must be explicitly enabled per key, and the CLI output shows only the first key received the enabling command.
Detailed technical explanation
AWS KMS automatic key rotation rotates the key material of a customer managed key (CMK) annually (approximately 365 days) while preserving the key ID, ARN, and previous key material for decryption of older ciphertexts. The `EnableKeyRotation` API sets the `RotationPeriodInDays` to 365 by default; this cannot be changed. A common real-world scenario is compliance requirements (e.g., PCI DSS, SOC 2) that mandate cryptographic key rotation, making it critical to verify which keys have this feature enabled.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
