PAS-C01 Migration Practice Question
A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA as its database. The company has a complex networking setup with multiple VPCs and on-premises connectivity via AWS Direct Connect. The SAP HANA system replication will be used for high availability across two Availability Zones. What is the minimum number of Elastic Network Interfaces (ENIs) required per HANA instance to support the recommended network architecture?

Correct answer & explanation
✓
2
The minimum number of ENIs recommended for SAP HANA system replication across Availability Zones is 2. This allows separation of client traffic from HANA system replication traffic, which is a best practice. A single ENI can technically carry all traffic but does not adhere to the recommended network architecture. Option A (2) is the minimum, while Option B (1) is insufficient.
