PAS-C01 Migration Practice Question
Exhibit
Refer to the exhibit. The following is an AWS CLI command output:
{
"Replications": [
{
"ReplicationTaskIdentifier": "sap-migration-task",
"SourceEndpointArn": "arn:aws:dms:us-east-1:123456789012:endpoint:AAAA",
"TargetEndpointArn": "arn:aws:dms:us-east-1:123456789012:endpoint:BBBB",
"ReplicationTaskStats": {
"FullLoadProgressPercent": 100,
"TablesLoaded": 150,
"TablesLoading": 0,
"TablesQueued": 0,
"TablesErrored": 0,
"CdcLatencySource": 5000,
"CdcLatencyTarget": 5000
}
}
]
}A company is using AWS DMS to migrate an SAP database. The full load is complete, but the CDC latency is high. Which step should the company take to reduce latency?
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
✓
Increase the compute capacity of the DMS replication instance.
Increasing the compute capacity of the DMS replication instance provides more resources to process CDC changes, reducing latency. Option B is incorrect because increasing the target database size does not directly affect DMS replication performance. Option C is incorrect because restarting the task does not address the underlying resource constraint and may cause temporary downtime. Option D is incorrect because disabling CDC would stop replication entirely, not reduce latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Increase the compute capacity of the DMS replication instance.
Why this is correct
A larger replication instance can process CDC faster.
- ✗
Increase the size of the target database instance.
Why it's wrong here
Target size may not be the bottleneck; DMS instance size is more likely.
- ✗
Restart the DMS replication task.
Why it's wrong here
Restarting does not address performance issues.
- ✗
Disable change data capture (CDC) on the source database.
Why it's wrong here
Disabling CDC would stop capturing changes.
