Correct answer & explanation
✓
Shared file storage (e.g., Amazon EFS or EBS Multi-Attach)
A cluster manager like Pacemaker is required to orchestrate failover between the two ASCS nodes. Shared file storage (e.g., Amazon EFS or EBS Multi-Attach) provides a shared file system for /sapmnt and /usr/sap, which must be accessible from both nodes. A Network Load Balancer (NLB) distributes traffic to the active ASCS instance and performs health checks to detect failures. Options C and D are incorrect because a NAT Gateway and Internet Gateway are not required for SAP HA; they are used for outbound/inbound internet connectivity.

Shared file storage (e.g., Amazon EFS or EBS Multi-Attach)
Why this is correct
Shared storage ensures data consistency after failover.
- ✓
A cluster manager such as Pacemaker
Why this is correct
Pacemaker manages the failover of ASCS between nodes.
- ✗
A NAT Gateway for outbound traffic
Why it's wrong here
NAT Gateway is not required for HA; it's for internet access.
- ✗
An Internet Gateway for inbound traffic

Internet Gateway is for public internet access, not needed for HA.
- ✓
A Network Load Balancer to distribute traffic to ASCS
Why this is correct
NLB provides health checks and routes client requests to the active ASCS instance.
