DBS-C01 Monitoring and Troubleshooting Practice Question

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 DynamoDB table, then enable DynamoDB Streams, then add a replica table in another Region, then verify replication.

  Why this is correct

  This is the correct order because DynamoDB Streams must be enabled on the source table before adding a replica Region. After the replica is added, verification ensures data is being replicated.

• ✗

  Create a DynamoDB table, then add a replica table in another Region, then enable DynamoDB Streams, then verify replication.

  Why it's wrong here

  This is incorrect because DynamoDB Streams must be enabled before adding a replica Region. If you add a replica first, the replication will fail or not work properly.

• ✗

  Enable DynamoDB Streams, then create a DynamoDB table, then add a replica table in another Region, then verify replication.

  Why it's wrong here

  This is incorrect because you cannot enable DynamoDB Streams on a table that does not exist yet. The table must be created first.

• ✗

  Add a replica table in another Region, then create a DynamoDB table, then enable DynamoDB Streams, then verify replication.

  Why it's wrong here

  This is incorrect because you cannot add a replica Region before the source table exists, and streams must be enabled before replication starts.
