AWS Certified Database - Specialty Questions and Answers

Question 1

A company wants to migrate its existing on-premises Oracle database to Amazon Aurora PostgreSQL. The migration must be completed with minimal downtime using AWS DMS. A Database Specialist must validate that the data was migrated accurately from the source to the target before the cutover. The migration must have minimal impact on the performance of the source database.

Which approach will MOST effectively meet these requirements?

Options:

A.

Use the AWS Schema Conversion Tool (AWS SCT) to convert source Oracle database schemas to the target Aurora DB cluster. Verify the datatype of the columns.

B.

Use the table metrics of the AWS DMS task created for migrating the data to verify the statistics for the tables being migrated and to verify that the data definition language (DDL) statements are completed.

C.

Enable the AWS Schema Conversion Tool (AWS SCT) premigration validation and review the premigration checklist to make sure there are no issues with the conversion.

D.

Enable AWS DMS data validation on the task so the AWS DMS task compares the source and target records, and reports any mismatches.

Question 2

A company is running a business-critical application on premises by using Microsoft SQL Server. A database specialist is planning to migrate the instance with several databases to the AWS Cloud.

The solution must provide high availability and must avoid a single point of failure in the SQL Server deployment architecture.

Set up Always On availability groups to group one or more user databases that fail over together across multiple SQL Server instances. Use Multi-AZ Amazon FSx for Windows File Server as a shared storage option to host the databases.

D.

Create an Application Load Balancer to distribute database traffic across multiple EC2 instances in multiple Availability Zones. Use Amazon S3 as a shared storage option to host the databases.

Question 3

A company is load testing its three-tier production web application deployed with an AWS CloudFormation template on AWS. The Application team is making changes to deploy additional Amazon EC2 and AWS Lambda resources to expand the load testing capacity.
