AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 67

A company has run SAP HANA on AWS for a few years on an Amazon EC2 X1 instance with dedicated tenancy. Because of business growth, the company plans to migrate to an EC2 High Memory instance by using a resize operation. The SAP HANA system is set up for high availability with SAP HANA system replication and clustering software.

Which combination of steps should the company take before the migration? (Choose three.)

Answer options

• A. Ensure that the source system is running on a supported operating system version.
• B. Update all references to the IP address of the source system, including the /etc/hosts file for the operating system and DNS entries, to reflect the new IP address.
• C. Adjust the storage size of SAP HANA data, log, shared, and backup volumes.
• D. Resize the instance through the AWS Management Console or the AWS CLI.
• E. Ensure that there is a backup of the source system.
• F. Update the DNS records. Check the connectivity between the SAP application servers and the new SAP HANA instance.

Correct answer: A, D, E

Explanation

The correct steps include ensuring the source system's operating system is supported (A), resizing the instance through the proper channels (D), and having a backup (E) to prevent data loss. Options B and F, while important for addressing connectivity issues, are not prerequisites for the migration process itself, and option C may not be necessary if the new instance can accommodate existing storage configurations.
