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
✓
Create a manual snapshot of 'production-db' with the name 'mydb-production-snapshot'.
The IAM policy allows CreateDBSnapshot only on DB instances with names starting with 'mydb-', and the snapshot name must also match the pattern 'mydb-*'. The snapshot name 'mydb-production-snapshot' satisfies that pattern. Option A is wrong because 'production-db-snapshot' does not start with 'mydb-'. Option C is wrong because the question asks about creating a snapshot, not describing instances. Option D is wrong because the policy does not grant DeleteDBInstance permission.
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 snapshot of 'production-db' with the name 'production-db-snapshot'.
Why it's wrong here
The snapshot name must start with 'mydb-' to match the resource ARN pattern.
- ✓
Create a manual snapshot of 'production-db' with the name 'mydb-production-snapshot'.
Why this is correct
The snapshot name starts with 'mydb-', matching the allowed resource pattern.
- ✗
Describe the 'production-db' DB instance.
Why it's wrong here
The user can describe instances, but the question asks which action the user will be able to perform; the answer should be the snapshot creation with the correct name.
- ✗
Delete the 'production-db' DB instance.
Why it's wrong here
The Deny statement explicitly denies rds:DeleteDBInstance.
