Question 31

A company is load testing its three-tier production web application deployed with an AWS CloudFormation template on AWS. The Application team is making changes to deploy additional Amazon EC2 and AWS Lambda resources to expand the load testing capacity. A Database Specialist wants to ensure that the changes made by the Application team will not change the Amazon RDS database resources already deployed.
Which combination of steps would allow the Database Specialist to accomplish this? (Choose two.)

A.Create and review a change set before applying it
B.Export the database resources as stack outputs
C.Set a stack policy for the database resources
D.Review the stack drift before modifying the template
E.Define the database resources in a nested stack

Question 32

A Database Specialist is migrating an on-premises Microsoft SQL Server application database to Amazon RDS for PostgreSQL using AWS DMS. The application requires minimal downtime when the RDS DB instance goes live.
What change should the Database Specialist make to enable the migration?

A.Configure the AWS DMS connections to allow two-way communication to allow for ongoing change data capture (CDC)
B.Configure the AWS DMS task to generate full logs to allow for ongoing change data capture (CDC)
C.Configure the AWS DMS replication instance to allow both full load and ongoing change data capture (CDC)
D.Configure the on-premises application database to act as a source for an AWS DMS full load with ongoing change data capture (CDC)

Question 33

A gaming company wants to deploy a game in multiple Regions. The company plans to save local high scores in Amazon DynamoDB tables in each Region. A Database Specialist needs to design a solution to automate the deployment of the database with identical configurations in additional Regions, as needed. The solution should also automate configuration changes across all Regions.
Which solution would meet these requirements and deploy the DynamoDB tables?

A.Create DynamoDB tables using the AWS Management Console in all the Regions and create a step-bystep guide for future deployments.
B.Create an AWS CloudFormation template and use a stack set to deploy the template to all the Regions.
C.Create an AWS CloudFormation template and deploy the template to all the Regions.
D.Create an AWS CLI command to deploy the DynamoDB table to all the Regions and save it for future deployments.

Question 34

A Database Specialist must create a read replica to isolate read-only queries for an Amazon RDS for MySQL DB instance. Immediately after creating the read replica, users that query it report slow response times.
What could be causing these slow response times?

A.Insufficient resources on the master
B.New volumes created from snapshots load lazily in the background
C.Overload of a single replication thread by excessive writes on the master snapshot is lazy loaded If the volume is accessed where the data is not loaded, the application accessing the volume encounters a higher latency than normal while the data gets loaded
D.Long-running statements on the master

Question 35

A company wants to migrate its on-premises MySQL databases to Amazon RDS for MySQL. To comply with the company's security policy, all databases must be encrypted at rest. RDS DB instance snapshots must also be shared across various accounts to provision testing and staging environments.
Which solution meets these requirements?

A.Create an RDS for MySQL DB instance with an AWS CloudHSM key. Update the key policy to include the Amazon Resource Name (ARN) of the other AWS accounts as a principal, and then allow the kms:CreateGrant action.
B.Create an RDS for MySQL DB instance with an AWS owned CMK. Create a new key policy to include the administrator user name of the other AWS accounts as a principal, and then allow the kms:CreateGrant action.
C.Create an RDS for MySQL DB instance with an AWS managed CMK. Create a new key policy to include the Amazon Resource Name (ARN) of the other AWS accounts as a principal, and then allow the kms:CreateGrant action.
D.Create an RDS for MySQL DB instance with an AWS Key Management Service (AWS KMS) customer managed CMK. Update the key policy to include the Amazon Resource Name (ARN) of the other AWS accounts as a principal, and then allow the kms:CreateGrant action.
