A company wants 10 migrate its SAP ERP landscape to AWS The company will use a highly available distributed deployment for the new architecture Clients will access SAP systems from a local data center through an AWS Site-to-Site VPN connection that is already in place An SAP solutions architect needs to design the network access to the SAP production environment
Which configuration approaches will meet these requirements? (Select TWO.)
Option B is correct because it uses AWS Direct Connect gateway with multiple Direct Connect connections that use a link aggregation group (LAG) between the on-premises data center and AWS. This provides high availability and redundancy for the network connection, as well as increased bandwidth and lower latency. It also allows the use of an overlay IP address that is outside the production VPC CIDR range for the ASCS instance, which is recommended by SAP for high availability.
Option D is correct because it uses two redundant AWS Site-to-Site VPN connections for connectivity between the on-premises data center and AWS. This provides a backup connection in case one of the VPN connections fails. It also allows the use of an overlay IP address that is outside the production VPC CIDR range for the ASCS instance, which is recommended by SAP for high availability.
Option A is incorrect because it uses an overlay IP address that is within the production VPC CIDR range for the ASCS instance, which is not recommended by SAP for high availability. It also uses only one AWS Direct Connect connection, which does not provide redundancy or load balancing for the network connection.
Option C is incorrect because it uses Amazon Elastic File System (Amazon EFS) file system storage between the on-premises data center and AWS, which is not a network configuration for data transfer. It also uses an Application Load Balancer, which does not support TCP protocol for the ASCS instance.
Option E is incorrect because it uses an Application Load Balancer, which does not support TCP protocol for the ASCS instance. It also uses a target group that points to the overlay IP address, which is not necessary for the network access to the ASCS instance.

A data analysis company has two SAP landscapes that consist of sandbox development QA, pre-production and production servers. One landscape is on Windows and the other landscape is on Red Hat Enterprise Linux. The servers reside in a room m a building that other tenants share.
An SAP solutions architect proposes to migrate the SAP applications to AWS The SAP solutions architect wants to move the production backups to AWS and wants to make the backups highly available to restore >n case of unavailability of an on-premises server.
Which solution will meet these requirements MOST cost-effectively?
Take a backup of the production servers, Implement an Amazon S3 File Gateway, Create file shares by using the S3 File Gateway, Copy the backup files to the file shares through NFS and SMB, Map backup files directly to Amazon S3 and Configure an S3 Lifecycle policy to send the backup files to S3 Glacier based on the company's data retention policy. This option is cost-effective because it avoids the need for third-party tools, tape drives and storage gateways, and reduces the amount of time and resources needed for the migration process. Additionally, the S3 lifecycle policy allows you to automate the storage and archiving process and ensure that your data is stored in the most cost-effective way.
A company is running an SAP HANA database on AWS The company is running AWS Backint Agent for SAP HANA(AWS Backint agent) on an Amazon EC2 instance AWS Back agent is configured to back up to an Amazon S3 bucket The backups are failing with an Access Denied error m the AWS Backint agent log file.
What should an SAP basis administrator do to resolve this error?
The error message 'AccessDenied' usually indicates that the AWS Backint agent does not have the necessary permissions to access the target S3 bucket. To resolve this error, an SAP basis administrator should assign an IAM role to the EC2 instance that is running the AWS Backint agent. Then, the administrator should attach a policy to the IAM role that grants the necessary permissions to access the target S3 bucket. This will allow the AWS Backint agent to access the S3 bucket and complete the backups successfully.
A company is running SAP on anyDB at a remote location that has slow and inconsistent internet connectivity. The company wants to migrate its system to AWS and wants to convert its database to SAP HANA during this process Because of the inconsistent internet connection the company has not established connectivity between the remote location and the company's VPC in the AWS Cloud.
How should the company perform this migration?
Snowball Edge allows for offline data transfer, which is suitable for cases where there is slow and inconsistent internet connectivity. The data can be transferred to the Snowball Edge device, shipped to the AWS region, and then imported into the new SAP HANA system in the VPC. This is a suitable option for migrating large amounts of data from a remote location to AWS.

A company is using a multi-account strategy for SAP HANA and SAP BW 4HANA instances across development QA and production systems m the same AWS Region Each system is hosted m its own VPC The company needs to establish cross-VPC communication between the SAP systems.
The company might add more SAP systems m the future. The company must create connectivity across the SAP systems and hundreds of AWS accounts. The solution must maximize scalability and reliability.
Which solution will meet these requirements?
Create an AWS Transit Gateway in a central networking account and attach the transit gateway to the AWS accounts. This solution will meet the requirements as it will maximize scalability and reliability and provide connectivity between the SAP systems and hundreds of AWS accounts. Additionally, as more SAP systems might be added in the future, this solution will also be able to handle the increased load.
