DBS-C01 Management and Operations Practice Question
A company is using Amazon DynamoDB with global tables. The application writes to a table in the us-east-1 region. The database administrator notices that updates made in us-east-1 are not appearing in the replica table in eu-west-1. What is the most likely cause?
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
✓
DynamoDB Streams are not enabled on the table.
DynamoDB global tables rely on DynamoDB Streams to replicate changes. If streams are not enabled, updates will not be replicated to other regions. Option B is incorrect because DynamoDB does not have a configurable replication delay; replication is near real-time. Option C is incorrect because point-in-time recovery is a backup feature and does not affect replication. Option D is incorrect because insufficient IAM permissions would typically cause error messages or failures, not a silent lack of replication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
DynamoDB Streams are not enabled on the table.
Why this is correct
Global tables require DynamoDB Streams to be enabled for replication to work.
- ✗
The replication delay is set too high.
Why it's wrong here
There is no replication delay setting in DynamoDB global tables.
- ✗
Point-in-time recovery is not enabled on the replica table.
Why it's wrong here
Point-in-time recovery is independent of replication.
- ✗
The IAM role for replication does not have sufficient permissions.
Why it's wrong here
Insufficient permissions would result in errors, not silent failure.
