AWS Certified Database – Specialty — Question 186

A company wants to migrate its on-premises Oracle database to Amazon RDS for PostgreSQL by using AWS Database Migration Service (AWS DMS). A database specialist needs to evaluate the migration task settings and data type conversion in an AWS DMS task.

What should the database specialist do to identify the optimal migration method?

Answer options

• A. Use the AWS Schema Conversion Tool (AWS SCT) database migration assessment report
• B. Use the AWS Schema Conversion Tool (AWS SCT) multiserver assessor.
• C. Use an AWS DMS pre-migration assessment
• D. Use the AWS DMS data validation tool

Correct answer: C

Explanation

The correct answer is C, as conducting an AWS DMS pre-migration assessment helps identify potential challenges and optimal strategies for the migration. Option A, while useful, does not specifically focus on pre-migration assessment, and options B and D are not directly related to evaluating migration methods but rather tools for assessment and validation.
