Amazon Exam PAS-C01 Topic 3 Question 40 Discussion

Actual exam question for Amazon's PAS-C01 exam

Question #: 40
Topic #: 3

A company runs its SAP ERP 6 0 EHP 8 system on SAP HANAon AWS The system is deployed on an r4 I6xlarge Amazon EC2 instance with default tenancy. The company needs to migrate the SAP HANA database to an x2gd/.6xiarge 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?

AThe operations engineer missed the network configuration step during the post-migration activities

BThe operations engineer missed the Amazon CloudWatch configuration step during the post-migration activities.

CThe operations engineer did not install Elastic Network Adapter (ENA) drivers before changing the instance type

DThe 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

Show Suggested Answer

Suggested Answer: C

The Elastic Network Adapter (ENA) is a software-based network interface that provides high-performance network connectivity and is required for instances with higher network performance requirements. If the ENA drivers are not installed before changing the instance type, the instance will not be able to communicate with the network, resulting in a failed instance status check.

C is correct because installing Elastic Network Adapter (ENA) drivers before changing the instance type is required to support High Memory instances. ENA drivers provide enhanced networking capabilities for EC2 instances. The other options are not relevant or necessary for migrating SAP HANA database to a High Memory instance.

I'm guessing the network configuration was the issue here. Seems like a silly oversight, but these things happen, especially with complex migrations.

B: Yeah, that could definitely cause the failed instance status check. It's important to double check all the steps in a migration like this.

Haha, classic AWS gotcha. Bet the engineer is kicking themselves for not checking the ENA drivers. Gotta love these cloud migration challenges!

Hmm, this is a tricky one. I'd say the engineer should have created a new AMI and launched a new instance with dedicated tenancy. But I could be wrong.

I think the operations engineer should have created a new AMI and launched a new instance with dedicated tenancy. That could have prevented the failed status check.

I believe the cause could also be that the operations engineer did not install Elastic Network Adapter (ENA) drivers before changing the instance type.

Yep, that's gotta be it. The lack of ENA drivers is definitely causing the failed instance status check.

Maybe the operations engineer can try installing the ENA drivers and see if that resolves the issue.
