This CCSP practice question tests your understanding of cloud security operations. 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.
A company uses a cloud key management service with automatic annual key rotation. An auditor requires that keys are rotated every 90 days to meet internal policy. What should the cloud security architect do to satisfy this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the cloud KMS with a custom rotation period of 90 days.
Option C is correct because cloud KMS services (e.g., AWS KMS, Azure Key Vault, GCP Cloud KMS) allow administrators to define a custom rotation period, overriding the default annual rotation. By configuring a 90-day rotation schedule, the architect directly meets the auditor's policy without manual intervention or exceptions, ensuring automated compliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 manual process to rotate keys every 90 days using scripts.
Why it's wrong here
Manual processes increase risk and are not recommended for security operations.
✗
Request an exception from the auditor because the default annual rotation is sufficient.
Why it's wrong here
Auditors typically require compliance; an exception is unlikely.
✓
Configure the cloud KMS with a custom rotation period of 90 days.
Why this is correct
Cloud KMS allows custom rotation policies; the architect should use it.

Read the scenario before looking for a memorised answer.
✗
Disable automatic rotation and rotate keys manually when needed.
Why it's wrong here
Disabling auto-rotation does not solve the problem.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the misconception that manual rotation or exception requests are acceptable workarounds, but the correct approach is to leverage the cloud KMS's built-in configuration to automate compliance with the required rotation interval.
Detailed technical explanation
How to think about this question
Cloud KMS services typically use a backing key (key encryption key) that is rotated by creating a new cryptographic material version while retaining the old one for decryption of existing data. The rotation period is defined in days (e.g., AWS KMS allows 90–2560 days, GCP Cloud KMS allows any integer between 1 and 1,000,000 days). Under the hood, the service automatically generates a new key version on the scheduled date and updates the primary key alias, ensuring seamless transition without re-encrypting data. In a real-world scenario, failing to set a custom rotation period could lead to audit findings and potential non-compliance with regulations like PCI DSS or HIPAA, which often require key rotation every 90 days.

→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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
