PAS-C01 Design of SAP Workloads on AWS Practice Question
Network Topology
An SAP administrator runs the AWS CLI command shown in the exhibit to check the configuration of an SAP HANA EC2 instance. The instance is running in us-east-1a. They need to deploy a second SAP HANA instance for high availability in a different Availability Zone. Which Availability Zone should be used?
⚠ Common exam trap
Candidates often confuse 'different Availability Zone' with 'different region' (option A) or assume any zone works (option C), but SAP HANA high availability specifically requires a different AZ within the same region to maintain synchronous replication and low latency.

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
✓
us-east-1b
For SAP HANA high availability, the secondary instance must be deployed in a different Availability Zone within the same AWS Region to achieve multi-AZ resilience. Since the primary instance is in us-east-1a, the correct choice is us-east-1b, which is a distinct Availability Zone in the same region (us-east-1). This ensures low-latency replication and compliance with SAP's requirement for synchronous replication within a single region.
Answer analysis
Option-by-option breakdown

- ✗
us-west-2a
Why it's wrong here
Different region is for DR, not HA.
- ✓
us-east-1b
Why this is correct
Different AZ in same region provides HA.
- ✗
Any Availability Zone
Why it's wrong here
Must be different from primary.
- ✗
us-east-1a
Why it's wrong here
Same AZ does not provide HA.
