178. Frage
A company recently migrated its line-of-business (LOB) application to AWS. The application uses an Amazon RDS for SQL Server DB instance as its database engine.
The company must set up cross-Region disaster recovery for the application. The company needs a solution with the lowest possible RPO and RTO.
Which solution will meet these requirements?

A. Take manual snapshots of the DB instance in the primary Region. Copy the snapshots to the disaster recovery Region.
B. Set up SQL replication from the DB instance to an Amazon EC2 instance in the disaster recovery Region. Promote the EC2 instance as the primary server.
C. Create a cross-Region read replica of the DB instance. Promote the read replica at the time of failover.
D. Use AWS Database Migration Service (AWS KMS) for ongoing replication of the DB instance in the disaster recovery Region.

Antwort: D

Begründung:

The marketing team has noticed some unexpected updates to the product and pricing information on the website, which is impacting sales targets. The marketing team wants a database specialist to audit future database activity to help identify how and when the changes are being made.
What should the database specialist do to meet these requirements? (Choose two.)

A. SSH to the DB instance and review the database logs.
B. Enable auditing of CONNECT and QUERY_DML events.
C. Enable Enhanced Monitoring on the DB instance.
D. Create an RDS event subscription to the audit event type.

180. Frage
A company's database specialist implements an AWS Database Migration Service (AWS DMS) task for change data capture (CDC) to replicate data from an on- premises Oracle database to Amazon S3. When usage of the company's application increases, the database specialist notices multiple hours of latency with the CDC.
Which solutions will reduce this latency? (Choose two.)

A. Load tables in parallel by creating multiple replication instances for sets of tables that participate in common transactions.
B. Replicate tables in parallel by creating multiple DMS tasks for sets of tables that do not participate in common transactions.
C. Configure the DMS task to run in limited large binary object (LOB) mode.
D. Create a Multi-AZ replication instance.
E. Configure the DMS task to run in full large binary object (LOB) mode.

Antwort: B,C

181. Frage
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?

A. 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.
B. 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.
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. 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.

Antwort: C

Begründung:
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.

182. Frage
A company has an application that uses an Amazon DynamoDB table to store user dat a. Every morning, a single-threaded process calls the DynamoDB API Scan operation to scan the entire table and generate a critical start-of-day report for management. A successful marketing campaign recently doubled the number of items in the table, and now the process takes too long to run and the report is not generated in time.
A database specialist needs to improve the performance of the process. The database specialist notes that, when the process is running, 15% of the table's provisioned read capacity units (RCUs) are being used.
What should the database specialist do?

A. Set the Limit and Offset parameters before every call to the API.
B. Double the table's provisioned RCUs.
C. Enable auto scaling for the DynamoDB table.
D. Use four threads and parallel DynamoDB API Scan operations.

Antwort: D
