[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

A company needs to implement high availability for its SAP S/4HANA system on AWS. The company will use a SUSE Linux Enterprise Server clustering solution in private subnets across two Availability Zones. An SAP solutions architect must ensure that the solution can route traffic to the active SAP instance in this clustered configuration.
What should the SAP solutions architect do to meet these requirements?

A. Implement the SAP cluster solution by using a secondary private IP address. Reassign the secondary private IP address from one network interface to another network interface in the event of any failure that affects the primary instance.
B. Implement the SAP cluster solution by using an Elastic IP address. Mask the failure of an instance or software by rapidly remapping the address to another instance in the account.
C. Implement the SAP cluster solution by using a public IP address. Use this public IP address for communication between the instances and the internet.
D. Implement the SAP cluster solution by using an overlay IP address that is outside the CIDR block of the VPC. Use overlay IP address routing to dynamically update the route table to point to the active node and provide external access by using a Network Load Balancer or AWS Transit Gateway.

D: In a SUSE Linux Enterprise Server cluster for SAP, an overlay IP address is used for high availability. This overlay IP address is associated with the active node in the cluster and gets reassigned to another node in case of a failure. To make this work, it's necessary to dynamically update the routing table to point the overlay IP address to the correct, active instance.
