Question No. 1

A gaming company has implemented a leaderboard in AWS using a Sorted Set data structure within Amazon ElastiCache for Redis. The ElastiCache cluster has been deployed with cluster mode disabled and has a replication group deployed with two additional replicas. The company is planning for a worldwide gaming event and is anticipating a higher write load than what the current cluster can handle.

Which method should a Database Specialist use to scale the ElastiCache cluster ahead of the upcoming event?

AEnable cluster mode on the existing ElastiCache cluster and configure separate shards for the Sorted Set across all nodes in the cluster.

BIncrease the size of the ElastiCache cluster nodes to a larger instance size.

CCreate an additional ElastiCache cluster and load-balance traffic between the two clusters.

DUse the EXPIRE command and set a higher time to live (TTL) after each call to increment a given key.

Question No. 2

A database specialist at a large multi-national financial company is in charge of designing the disaster recovery strategy for a highly available application that is in development. The application uses an Amazon DynamoDB table as its data store. The application requires a recovery time objective (RTO) of 1 minute and a recovery point objective (RPO) of 2 minutes.

Which operationally efficient disaster recovery strategy should the database specialist recommend for the DynamoDB table?

ACreate a DynamoDB stream that is processed by an AWS Lambda function that copies the data to a DynamoDB table in another Region.

BUse a DynamoDB global table replica in another Region. Enable point-in-time recovery for both tables.

CUse a DynamoDB Accelerator table in another Region. Enable point-in-time recovery for the table.

DCreate an AWS Backup plan and assign the DynamoDB table as a resource.

Correct Answer: C

Question No. 3

A company is concerned about the cost of a large-scale, transactional application using Amazon DynamoDB that only needs to store data for 2 days before it is deleted. In looking at the tables, a Database Specialist notices that much of the data is months old, and goes back to when the application was first deployed.

What can the Database Specialist do to reduce the overall cost?

ACreate a new attribute in each table to track the expiration time and create an AWS Glue transformation to delete entries more than 2 days old.

BCreate a new attribute in each table to track the expiration time and enable DynamoDB Streams on each table.

CCreate a new attribute in each table to track the expiration time and enable time to live (TTL) on each table.

DCreate an Amazon CloudWatch Events event to export the data to Amazon S3 daily using AWS Data Pipeline and then truncate the Amazon DynamoDB table.

Question No. 4

A company is running a blogging platform. 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?

ACreate 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.

BTake 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.

CCreate 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.

DConvert 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.

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 No. 5

A company is migrating its on-premises database workloads to the AWS Cloud. A database specialist performing the move has chosen AWS DMS to migrate an Oracle database with a large table to Amazon RDS. The database specialist notices that AWS DMS is taking significant time to migrate the data.

Which actions would improve the data migration speed? (Choose three.)

ACreate multiple AWS DMS tasks to migrate the large table.

BConfigure the AWS DMS replication instance with Multi-AZ.

CIncrease the capacity of the AWS DMS replication server.

DEstablish an AWS Direct Connect connection between the on-premises data center and AWS.

EEnable an Amazon RDS Multi-AZ configuration.

FEnable full large binary object (LOB) mode to migrate all LOB data for all large tables.
