This DBS-C01 practice question tests your understanding of database security. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 database administrator runs the described command. What does the output indicate about the RDS instance?
The DB instance is not encrypted at rest.
StorageEncrypted is false.
The DB instance is in a failed state.
Why wrong: The status is 'available'.
The DB instance is running PostgreSQL.
Why wrong: The engine is MySQL.
The DB instance is encrypted at rest using a KMS key.
Why wrong: StorageEncrypted is false.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The DB instance is not encrypted at rest.
Option C is correct. The output shows 'StorageEncrypted: false' and 'KmsKeyId: null', which means the instance is not encrypted at rest. Option A is incorrect because the instance is available. Option B is incorrect because the engine is MySQL. Option D is incorrect because the output clearly shows encryption status.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
