Explanation

A Multi-AZ solution with private subnets in each Availability Zone satisfies both requirements. Deploying SAP HANA and application servers across multiple AZs using SAP HANA System Replication ensures high availability and minimizes downtime - if one AZ becomes unavailable, the standby in the other AZ can take over quickly. Private subnets have no direct route to the internet, so no inbound internet access is possible, satisfying the security requirement. A Single-AZ solution (B) introduces a single point of failure and does not minimize downtime. Using public subnets (D) exposes instances to potential inbound internet traffic, violating the security requirement. Option C may differ in using public subnets or a single AZ, making A the only option that satisfies both HA and network isolation requirements.
