A security audit determines that the Amazon RDS DB instance that is used by the platform is not configured to encrypt the data at rest. The company must encrypt the DB instance within 30 days. What should a database specialist do to meet this requirement with the LEAST amount of downtime? A. Create a read replica of the DB instance, and enable encryption. When the read replica is available, promote the read replica and update the endpoint that is used by the application. Delete the unencrypted DB instance. B. Take a snapshot of the DB instance. Make an encrypted copy of the snapshot. Restore the encrypted snapshot. When the new DB instance is available, update the endpoint that is used by the application. Delete the unencrypted DB instance. C. Create a new encrypted DB instance. Perform an initial data load, and set up logical replication between the two DB instances When the new DB instance is in sync with the source DB instance, update the endpoint that is used by the application. Delete the unencrypted DB instance. D. Convert the DB instance to an Amazon Aurora DB cluster, and enable encryption. When the DB cluster is available, update the endpoint that is used by the application to the cluster endpoint. Delete the unencrypted DB instance. Correct Answer: C Explanation: https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/encrypt- an-existing-amazon-rds-for- postgresql-db-instance.html When the new, encrypted copy of the DB instance becomes available, you can point your applications to the new database. However, if your project doesn\\'t allow for significant downtime for this activity, you need an alternate approach that helps minimize the downtime. This pattern uses the AWS Database Migration Service (AWS DMS) to migrate and continuously replicate the data so that the cutover to the new, encrypted database can be done with minimal downtime. QUESTION 2 A user has a non-relational key-value database. The user is looking for a fully managed AWS service that will offload the administrative burdens of operating and scaling distributed databases. The solution must be cost- effective and able to handle unpredictable application traffic. What should a Database Specialist recommend for this user? A. Create an Amazon DynamoDB table with provisioned capacity mode B. Create an Amazon DocumentDB cluster C. Create an Amazon DynamoDB table with on-demand capacity mode D.

Create new Aurora Serverless DB clusters for development and reporting, then migrate to these new DB clusters. B. Upgrade one of the DB clusters to a larger size, and consolidate development and reporting activities on this larger DB cluster. C. Use existing DB clusters and stop/start the databases on a routine basis using scheduling tools. D. Change the DB clusters to the burstable instance family.

The RDS instance exhibits multi-second read and write latency, and uses all of its maximum bandwidth for read throughput, yet the instance uses less than half of its CPU and RAM resources. What should a Database Specialist do in this situation to increase performance and return latency to sub- second levels? A. Increase the size of the DB instance storage B. Change the underlying EBS storage type to General Purpose SSD (gp2) C. Disable EBS optimization on the DB instance D.

Then restore the backup in the target Region. C. Configure AWS Database Migration Service (AWS DMS) to replicate data between the source and the target databases. Once the replication is in sync, terminate the DMS task. D. Add an RDS for SQL Server cross-Region read replica in the target Region. Once the replication is in sync, promote the read replica to master. Correct Answer: C https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ReadRepl.XRgn.html With Amazon RDS, you can create a MariaDB, MySQL, Oracle, or PostgreSQL read replica in a different AWS Region from the source DB instance. Creating a cross-Region read replica isn\\'t supported for SQL Server on Amazon RDS.
