A large company is using an Amazon RDS for Oracle Multi-AZ DB instance with a Java application. As a part of its disaster recovery annual testing, the company would like to simulate an
Availability Zone failure and record how the application reacts during the DB instance failover activity. The company does not want to make any code changes for this activity.
What should the company do to achieve this in the shortest amount of time?
A. Use RDS fault injection queries to simulate the primary node failure
B. Use a blue-green deployment with a complete application-level failover test
C. Add a rule to the NACL to deny all traffic on the subnets associated with a single Availability Zone
D. Use the RDS console to reboot the DB instance by choosing the option to reboot with failover
Answer: A

QUESTION NO: 4
A company is using an Amazon Aurora PostgreSQL DB cluster with an xlarge primary instance master and two large Aurora Replicas for high availability and read-only workload scaling. A failover event occurs and application performance is poor for several minutes. During this time, application servers in all Availability Zones are healthy and responding normally.
What should the company do to eliminate this application performance issue?
A. Deploy an AWS Lambda function that calls the DescribeDBInstances action to establish which instancehas failed, and then use the PromoteReadReplica operation to promote one Aurora Replica to be theprimary DB instance. Configure an Amazon RDS event subscription to send a notification to an AmazonSNS topic to which the Lambda function is subscribed.
B. Configure both Aurora Replicas to have the same instance class as the primary DB instance.
ImplementAurora PostgreSQL DB cluster cache management. Set the failover priority to tier-0 for the primary DBinstance and to tier-1 for the replicas.
C. Configure one Aurora Replica to have the same instance class as the primary DB instance.
ImplementAurora PostgreSQL DB cluster cache management. Set the failover priority to tier-0 for the primary DBinstance and one replica with the same instance class. Set the failover priority to tier-1 for the otherreplicas.
D. Configure both of the Aurora Replicas to the same instance class as the primary DB instance.
Enablecache coherence on the DB cluster, set the primary DB instance failover priority to tier-0, and assign afailover priority of tier-1 to the replicas.
Answer: B
