Topic 1 · Question 121

A company is running SAP ERP Central Component (SAP ECC) on SAP HANA on premises. The current landscape runs on four application servers that use an SAP HANA database. The company is migrating this environment to the AWS Cloud. The cloud environment must minimize downtime during business operations and must not allow inbound access from the internet. Which solution will meet these requirements?

ADesign a Multi-AZ solution. In each Availability Zone, create a private subnet where Amazon EC2 instances that host the SAP HANA database and the application servers will reside. Use EC2 instances that are the same size to host the primary database and the secondary database. Use SAP HANA system replication in synchronous replication mode. (correct answer)
BDesign a Single-AZ solution. Create a private subnet where a single SAP HANA database and application servers will run on Amazon EC2 instances.
CDesign a Multi-AZ solution. In each Availability Zone, create a private subnet where Amazon EC2 instances that host the SAP HANA database and the application servers will reside. Shut down the EC2 instance that runs the secondary database node. Turn on this EC2 instance only when the primary database node or the primary database node's underlying EC2 instance is unavailable.

Topic 1 · Question 123

A company is deploying SAP landscapes in a single AWS account. The company must use separate VPCs to host its production environment and non-production environment. The company is using an Amazon Elastic File System (Amazon EFS) file system to host the SAP transport file systems. An SAP engineer attempts to use AWS Launch Wizard for SAP to perform an automated SAP deployment of the production environment. A deployment failure occurs when the SAP engineer attempts to reuse the SAP transport directory share from the non-production environment. This failure did not occur in previous non-production deployments. The SAP engineer needs to complete the deployment and ensure that no additional costs are incurred for SAP transport directories. What should the SAP engineer do to meet these requirements?

APerform a manual deployment.
BSet up a new SAP transport directory for the production environment. Copy all files from the non-production transport host into the production transport directory by using rsync. Continue to use separate SAP transport directories for the systems.
CSet up a transit gateway or direct VPC peering to make communication possible between the production VPC and the non-production VPC. (correct answer)
DSkip the SAP transport directories step to complete the deployment.
