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
✓
dms:DescribeEndpoints and dms:CreateEndpoint
The policy allows DMS actions and S3 bucket access, but does not include permissions for source database endpoints (e.g., RDS or EC2). DMS needs permissions to describe and connect to the source. kms:Decrypt is not relevant unless encryption is used. ec2:DescribeSubnets is for network settings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
dms:DescribeEndpoints and dms:CreateEndpoint
Why this is correct
DMS needs permissions to manage endpoints.
- ✗
kms:Decrypt
Why it's wrong here
Not needed unless the source is encrypted.
- ✗
rds:DescribeDBInstances
Why it's wrong here
If source is RDS, but the policy does not include it; however, the error is about accessing source, not describing.
- ✗
ec2:DescribeSubnets
Why it's wrong here
Replication instance network settings, but not source access.
