AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 64

A company runs its SAP ERP 6.0 EHP 8 system on SAP HANA on AWS. The system is deployed on an r4.16xlarge Amazon EC2 instance with default tenancy. The company needs to migrate the SAP HANA database to an x2gd.16xlarge High Memory instance. After an operations engineer changes the instance type and starts the instance, the AWS Management Console shows a failed instance status check.
What is the cause of this problem?

Answer options

• A. The operations engineer missed the network configuration step during the post-migration activities.
• B. The operations engineer missed the Amazon CloudWatch configuration step during the post-migration activities.
• C. The operations engineer did not install Elastic Network Adapter (ENA) drivers before changing the instance type.
• D. The operations engineer did not create a new AMI from the original instance and did not launch a new instance with dedicated tenancy from the AMI.

Correct answer: C

Explanation

The correct answer is C because the Elastic Network Adapter (ENA) drivers are essential for the new instance type to function correctly. If these drivers are not installed before changing the instance type, it can lead to a failed status check. Options A and B address configuration steps that are not directly related to the status check failure, while option D pertains to AMI creation rather than driver installation, which is the root cause of the issue.
