AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 86
A company is running its production SAP HANA system on AWS. The SAP HANA system is hosted on an Amazon EC2 instance that runs SUSE Linux Enterprise Server 12. The operating system patch version is out of date, and SAP has identified some critical security vulnerabilities.
SUSE publishes a critical patch update that requires a system restart to fix the issue. The company must apply this patch along with many prerequisite patches.
Which solution will meet these requirements with the LEAST system downtime?
Answer options
- A. Use the SUSE Linux Enterprise Server patching update process and SUSE tools to apply the required patches to the existing instance.
- B. Use AWS Systems Manager Patch Manager to automatically apply the patches to the existing instance.
- C. Use AWS Launch Wizard for SAP to provision a second SAP HANA instance with an AMI that contains the required patches. Use SAP HANA system replication to copy the data from the original SAP HANA instance to the newly launched SAP HANA instance. Perform SAP HANA system replication takeover.
- D. Use AWS Launch Wizard for SAP to provision a second SAP HANA instance with an AMI that contains the required patches. Use SAP HANA native backup and restore to copy the data from the original SAP HANA instance to the newly launched SAP HANA instance.
Correct answer: C
Explanation
Option C is the correct choice because it allows for setting up a new instance with the necessary patches while the original instance remains operational, thus minimizing downtime during the patching process. The other options either require downtime to apply patches directly to the existing instance or do not efficiently facilitate the replication of the SAP HANA system, leading to longer system unavailability.
