AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 89

A company runs its SAP Business Suite on SAP HANA systems on AWS. The company's production SAP ERP Central Component (SAP ECC) system uses an x1e.32xlarge (memory optimized) Amazon EC2 instance and is 3.5 TB in size.

Because of expected future growth, the company needs to resize the production system to use a u-* EC2 High Memory instance. The company must resize the system as quickly as possible and must minimize downtime during the resize activities.

Which solution will meet these requirements?

Answer options

• A. Resize the instance by using the AWS Management Console or the AWS CLI.
• B. Create an AMI of the source system Launch a new EC2 High Memory instance that is based on that AMI.
• C. Launch a new EC2 High Memory instance. Install and configure SAP HANA on the new instance by using AWS Launch Wizard for SAP. Use SAP HANA system replication to migrate the data to the new instance.
• D. Launch a new EC2 High Memory instance. Install and configure SAP HANA on the new instance by using AWS Launch Wizard for SAP. Use SAP HANA backup and restore to back up the source system directly to Amazon S3 and to migrate the data to the new instance.

Correct answer: C

Explanation

Option C is the correct answer because it allows for minimal downtime by leveraging SAP HANA system replication, which enables the data to be synchronized with the new instance while the old instance remains operational. Options A and B do not adequately minimize downtime during the resizing process, while option D introduces unnecessary complexity and potential downtime by relying on backup and restore procedures.
