Question 2

A company has an on-premises production Microsoft SQL Server with 250 GB of data in one database. A database specialist needs to migrate this on-premises

SQL Server to Amazon RDS for SQL Server. The nightly native SQL Server backup file is approximately 120 GB in size. The application can be down for an extended period of time to complete the migration. Connectivity between the on-premises environment and AWS can be initiated from on-premises only.

How can the database be migrated from on-premises to Amazon RDS with the LEAST amount of effort?

Options:

A.

Back up the SQL Server database using a native SQL Server backup. Upload the backup files to Amazon S3. Download the backup files on an Amazon EC2 instance and restore them from the EC2 instance into the new production RDS instance.

B.

Back up the SQL Server database using a native SQL Server backup. Upload the backup files to Amazon S3. Restore the backup files from the S3 bucket into the new production RDS instance.

C.

Provision and configure AWS DMS. Set up replication between the on-premises SQL Server environment to replicate the database to the new production RDS instance.

Question 3

A company has deployed an application that uses an Amazon RDS for MySQL DB cluster. The DB cluster uses three read replicas. The primary DB instance is an

8XL-sized instance, and the read replicas are each XL-sized instances.

Users report that database queries are returning stale data. The replication lag indicates that the replicas are 5 minutes behind the primary DB instance. Status queries on the replicas show that the SQL_THREAD is 10 binlogs behind the IO_THREAD and that the IO_THREAD is 1 binlog behind the primary.

Which changes will reduce the lag? (Choose two.)

Options:

A.

Deploy two additional read replicas matching the existing replica DB instance size.

B.

Migrate the primary DB instance to an Amazon Aurora MySQL DB cluster and add three Aurora Replicas.

C.

Move the read replicas to the same Availability Zone as the primary DB instance.

D.

Increase the instance size of the primary DB instance within the same instance class.

E.

Increase the instance size of the read replicas to the same size and class as the primary DB instance.
