PAS-C01 Technology Practice Question
Network Topology
An SAP administrator runs the AWS CLI command shown in the exhibit. The SAP HANA instance is running on an r5.4xlarge in us-east-1a. The administrator wants to change the instance type to r5.8xlarge to improve performance. What must the administrator do first?
⚠ Common exam trap
It's easy for candidates to think the instance type can be changed while running (Option D) because some instance attributes can be modified on the fly, but the instance type specifically requires the instance to be stopped.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Stop the instance from the AWS Management Console.
To change the instance type of an EC2 instance, the instance must first be stopped. While stopped, you can modify the instance type via the AWS Management Console, CLI, or SDK. After the instance is stopped, the administrator can change the type from r5.4xlarge to r5.8xlarge and then start the instance again.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an AMI of the instance and launch a new instance with the larger type.
Why it's wrong here
Not necessary; you can change type directly.
- ✗
Detach the EBS volumes and attach them to a new instance.
Why it's wrong here
Unnecessary; you can change instance type without detaching volumes.
- ✓
Stop the instance from the AWS Management Console.
Why this is correct
Instance must be stopped to modify instance type.
- ✗
Modify the instance type in the instance settings while it is running.
Why it's wrong here
