PAS-C01 Operations and Maintenance Practice Question
An SAP system on AWS uses an Auto Scaling group for the application tier. The scaling policy is based on the average CPU utilization of the EC2 instances. During peak hours, the system scales out, but the new instances take a long time to become available because they need to install SAP software and configure them. This delay causes performance degradation. The operations team wants to reduce the time to scale out. Which solution should they implement?

Correct answer & explanation
✓
Create a custom AMI with SAP software pre-installed and use it in the launch configuration.
The correct solution is to create a custom AMI with SAP software pre-installed and use it in the launch configuration. This approach eliminates the need for software installation and configuration at instance launch, significantly reducing the time for new instances to become available. Option A is incorrect because increasing instance size does not reduce boot time; it only provides more resources. Option C is incorrect because AWS Elastic Beanstalk is a platform-as-a-service offering that is not optimized for SAP workloads and would require significant reconfiguration. Option D is incorrect because instance store-backed AMIs are ephemeral and data is lost on instance stop/termination, which is not suitable for persistent SAP installations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the instance size to reduce boot time.
Why it's wrong here
Instance size has minimal impact on boot time.
- ✓
Create a custom AMI with SAP software pre-installed and use it in the launch configuration.
Why this is correct
Custom AMI reduces provisioning time.
- ✗
Switch to AWS Elastic Beanstalk for automatic scaling.
Why it's wrong here
Elastic Beanstalk is not designed for SAP workloads.
- ✗
Use an instance store-backed AMI instead of EBS-backed.
Why it's wrong here
Instance store does not persist data and is not suitable.
