QUESTION NO: 1
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: 2
An IT consulting company wants to reduce costs when operating its development environment databases. The company's workflow creates multiple Amazon Aurora MySQL DB clusters for each development group. The Aurora DB clusters are only used for 8 hours a day. The DB clusters can then be deleted at the end of the development cycle, which lasts 2 weeks.
Which of the following provides the MOST cost-effective solution?
A. Use AWS CloudFormation templates. Deploy a stack with the DB cluster for each development group.Delete the stack at the end of the development cycle.
B. Use Aurora Replicas. From the master automatic pause compute capacity option, create replicas for eachdevelopment group, and promote each replica to master. Delete the replicas at the end of the developmentcycle.
C. Use Aurora Serverless. Restore current Aurora snapshot and deploy to a serverless cluster for eachdevelopment group. Enable the option to pause the compute capacity on the cluster and set an appropriatetimeout.
D. Use the Aurora DB cloning feature. Deploy a single development and test Aurora DB instance, and createclone instances for the development groups. Delete the clones at the end of the development cycle.
Answer: C
QUESTION NO: 3

A. Set Java DNS caching timeouts to a high value.
B. Set JDBC connection string timeout variables to a low value.

D. Set TCP keepalive parameters to a high value.
E. Edit and enable Aurora DB cluster cache management in parameter groups.
F. Use the provided read and write Aurora endpoints to establish a connection to the Aurora DB cluster.
Answer: C,E,F
QUESTION NO: 5
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.
