Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Step 1: Create a replication instance. Step 2: Configure source and target endpoints. Step 3: Create a migration task. Step 4: Start the migration task. Step 5: Validate the migrated data.
Why this is correct
This is the correct order because AWS DMS requires a replication instance to be created first, followed by defining source and target endpoints, then creating a migration task that uses those endpoints. After creating the task, you start it and finally validate the data to ensure migration success.
- ✗
Step 1: Configure source and target endpoints. Step 2: Create a replication instance. Step 3: Create a migration task. Step 4: Start the migration task. Step 5: Validate the migrated data.
Why it's wrong here
This order is incorrect because endpoints reference the replication instance for connectivity, so the instance must be created before configuring endpoints. Configuring endpoints first will fail as the instance does not exist.
- ✗
Step 1: Create a replication instance. Step 2: Create a migration task. Step 3: Configure source and target endpoints. Step 4: Start the migration task. Step 5: Validate the migrated data.
Why it's wrong here
This order is incorrect because a migration task requires source and target endpoints to be defined before it can be created. Creating the task before endpoints will result in an error.
- ✗
Step 1: Create a replication instance. Step 2: Configure source and target endpoints. Step 3: Start the migration task. Step 4: Create a migration task. Step 5: Validate the migrated data.
Why it's wrong here
This order is incorrect because you cannot start a migration task that has not been created yet. The task must be created first, then started.
