PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP workload on AWS uses a single Availability Zone deployment. The company wants to improve high availability without changing the existing architecture significantly. Which action should be taken?
⚠ Common exam trap
Many exam-takers confuse scaling (increasing instance size) with high availability, or assume EBS Multi-Attach works across Availability Zones, when in fact it is restricted to a single AZ and specific volume types.

Correct answer & explanation
✓
Add a second SAP application server in a different Availability Zone and configure load balancing.
Adding a second SAP application server in a different Availability Zone and configuring load balancing provides high availability by distributing traffic across multiple AZs, ensuring that if one AZ fails, the application remains accessible. This approach aligns with SAP's recommended architecture for multi-AZ deployments without requiring significant changes to the existing single-AZ setup, as it only adds an additional application tier instance and a load balancer.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use an Amazon EBS volume attached to multiple instances across AZs.
Why it's wrong here
EBS volumes are AZ-specific; cannot attach across AZs.
- ✓
Add a second SAP application server in a different Availability Zone and configure load balancing.
Why this is correct
This provides application tier HA across AZs.
- ✗
Increase the size of the EC2 instances to handle failover.
Why it's wrong here
Larger instances do not provide HA.
- ✗
Enable EBS Multi-Attach on the database volume.
Why it's wrong here
Multi-Attach is for clustered file systems, not HA.
