A company is planning to close for several days. A Database Specialist needs to stop all applications alongwith the DB instances to ensure employees do not have access to the systems during this time. All databasesare running on Amazon RDS for MySQL.
The Database Specialist wrote and executed a script to stop all the DB instances. When reviewing the logs,the Database Specialist found that Amazon RDS DB instances with read replicas did not stop.
How should the Database Specialist edit the script to fix this issue?

A.Stop the read replicas before stopping their source instances
B.Use the AWS CLI to stop each read replica and source instance at the same
C.Stop the source instances before stopping their read replicas
D.Delete each read replica before stopping its corresponding source instance

Question 17

A Database Specialist is migrating a 2 TB Amazon RDS for Oracle DB instance to an RDS for PostgreSQL DB instance using AWS DMS. The source RDS Oracle DB instance is in a VPC in the us-east-1 Region. The target RDS for PostgreSQL DB instance is in a VPC in the use-west-2 Region.
Where should the AWS DMS replication instance be placed for the MOST optimal performance?

A.In the same Region and VPC as the target DB instance
B.In the same Region and VPC of the source DB instance
C.In the same VPC and Availability Zone as the target DB instance
D.In the same VPC and Availability Zone as the source DB instance

Question 18

A Database Specialist migrated an existing production MySQL database from on-premises to an Amazon RDS for MySQL DB instance. However, after the migration, the database needed to be encrypted at rest using AWS KMS. Due to the size of the database, reloading, the data into an encrypted database would be too time- consuming, so it is not an option.
How should the Database Specialist satisfy this new requirement?

A.Create a snapshot of the unencrypted RDS DB instance. Create an encrypted copy of the unencrypted snapshot. Restore the encrypted snapshot copy.
B.Modify the RDS DB instance. Enable the AWS KMS encryption option that leverages the AWS CLI.
C.Restore an unencrypted snapshot into a MySQL RDS DB instance that is encrypted.
D.Create an encrypted read replica of the RDS DB instance. Promote it the master.

Question 19

A company has a database fleet that includes an Amazon RDS for MySQL DB instance. During an audit, the company discovered that the data that is stored on the DB instance is unencrypted.
A database specialist must enable encryption for the DB instance. The database specialist also must encrypt all connections to the DB instance.
Which combination of actions should the database specialist take to meet these requirements? (Choose three.)

A.In the RDS console, choose "Enable encryption" to encrypt the DB instance by using an AWS Key Management Service (AWS KMS) key.
B.Encrypt the read replica of the unencrypted DB instance by using an AWS Key Management Service (AWS KMS) key. Fail over the read replica to the primary DB instance.
C.Create a snapshot of the unencrypted DB instance. Encrypt the snapshot by using an AWS Key Management Service (AWS KMS) key. Restore the DB instance from the encrypted snapshot. Delete the original DB instance.
D.Require SSL connections for applicable database user accounts.
E.Use SSL/TLS from the application to encrypt a connection to the DB instance.
F.Enable SSH encryption on the DB instance.

Question 20

A database specialist needs to replace the encryption key for an Amazon RDS DB instance. The database specialist needs to take immediate action to ensure security of the database.
Which solution will meet these requirements?

A.Modify the DB instance to update the encryption key. Perform this update immediately without waiting for the next scheduled maintenance window.
B.Export the database to an Amazon S3 bucket. Import the data to an existing DB instance by using the export file. Specify a new encryption key during the import process.
C.Create a manual snapshot of the DB instance. Restore the snapshot to a new DB instance. Specify a new encryption key during the restoration process.
D.Create a manual snapshot of the DB instance. Create an encrypted copy of the snapshot by using a new encryption key. Create a new DB instance from the encrypted snapshot.
