I passed my exam. Cramkey Dumps provides detailed explanations for each question and answer, so you can understand the concepts better.

I passed too. The questions I saw in the actual exam were exactly the same as the ones in the Cramkey Dumps. I was able to answer the questions confidently because I had already seen and studied them.

Question 73

A single MySQL database was moved to Amazon Aurora by a business. The production data is stored in a database cluster in VPC PROD, whereas 12 testing environments are hosted in VPC TEST with the same AWS account. Testing has a negligible effect on the test data. The development team requires that each environment be updated nightly to ensure that each test database has daily production data.

Which migration strategy will be the quickest and least expensive to implement?

Options:

Run the master in Amazon Aurora MySQL. Create 12 clones in VPC_TEST, and script the clones to be deleted and re-created nightly.

Run the master in Amazon Aurora MySQL. Take a nightly snapshot, and restore it into 12 databases in VPC_TEST using Aurora Serverless.

Run the master in Amazon Aurora MySQL. Create 12 Aurora Replicas in VPC_TEST, and script the replicas to be deleted and re-created nightly.

Run the master in Amazon Aurora MySQL using Aurora Serverless. Create 12 clones in VPC_TEST, and script the clones to be deleted and re-created nightly.

A Database Specialist is setting up a new Amazon Aurora DB cluster with one primary instance and three Aurora Replicas for a highly intensive, business-critical application. The Aurora DB cluster has one medium- sized primary instance, one large-sized replica, and two medium sized replicas. The Database Specialist did not assign a promotion tier to the replicas.

In the event of a primary failure, what will occur?

Options:

Aurora will promote an Aurora Replica that is of the same size as the primary instance

Aurora will promote an arbitrary Aurora Replica

Aurora will promote the largest-sized Aurora Replica

Aurora will not promote an Aurora Replica
