A company’s SAP basis team is responsible for database backups in Amazon S3. The company frequently needs to restore the last 3 months of backups into the pre-production SAP system to perform tests and analyze performance. Previously, an employee accidentally deleted backup files from the S3 bucket. The SAP basis team wants to prevent accidental deletion of backup files in the future.
Which solution will meet these requirements?
Enabling versioning and multi-factor authentication (MFA) on the S3 bucket will prevent accidental deletion while still allowing necessary deletions. Versioning allows for the preservation and retrieval of multiple versions of an object, ensuring that even if a backup file is accidentally deleted, it can be restored from a previous version. Multi-factor authentication (MFA) adds an additional layer of security, requiring users to provide two forms of authentication, which reduces the risk of accidental or unauthorized deletions.
A company wants to run SAP HANA on AWS in the eu-central-1 Region. The company must make the SAP HANA system highly available by using SAP HANA system replication. In addition, the company must create a disaster recovery (DR) solution that uses SAP HANA system replication in the eu-west-1 Region. As prerequisites, the company has confirmed that Inter-AZ latency is less than 1 ms and that Inter-Region latency is greater than 1 ms.
Which solutions will meet these requirements? (Choose two.)
To achieve high availability within the eu-central-1 region and disaster recovery in the eu-west-1 region, it is necessary to configure SAP HANA system replication correctly. For high availability within the same region (eu-central-1), SYNC or SYNCMEM replication mode is appropriate as both can handle less than 1 ms latency effectively. ASYNC replication mode is suitable for disaster recovery across regions (eu-west-1), considering the inter-region latency is greater than 1 ms. Option B sets up the primary system in one availability zone and the secondary system in another within the eu-central-1 region using SYNC replication, and uses ASYNC replication for the DR system in eu-west-1, ensuring both high availability and effective DR. Option E, similarly, uses SYNCMEM mode for the internal region replication and ASYNC for cross-region DR setup. These configurations align perfectly with the prerequisites and requirements.
A company is running an SAP ERP Central Component (SAP ECC) system on an SAP HANA database that is 10 TB in size. The company is receiving notifications about long-running database backups every day. The company uses AWS Backint Agent for SAP HANA (AWS Backint agent) on an Amazon EC2 instance to back up the database. An SAP NetWeaver administrator needs to troubleshoot the problem and propose a solution.
Which solution will help resolve this problem?
The UploadChannelSize parameter in the AWS Backint agent configuration file determines how many files can be uploaded in parallel during backups. Increasing this value will allow more files to be uploaded simultaneously, thereby reducing the overall time required for the backup process. This directly addresses the issue of long-running database backups by optimizing the upload performance. Ensuring proper configuration based on the EC2 instance type and storage configurations is crucial for achieving optimal backup performance.
A company wants to migrate its SAP workloads to AWS from another cloud provider. The company’s landscape consists of SAP S/4HANA, SAP BW/4HANA, SAP Solution Manager, and SAP Web Dispatcher. SAP Solution Manager is running on SAP HANA.
The company wants to change the operating system from SUSE Linux Enterprise Server to Red Hat Enterprise Linux as a part of this migration. The company needs a solution that results in the least possible downtime for the SAP S/4HANA and SAP BW/4HANA systems.
Which migration solution will meet these requirements?
The migration solution utilizing SAP HANA system replication for SAP S/4HANA and SAP BW/4HANA is the most appropriate for minimizing downtime. SAP HANA system replication ensures continuous data synchronization between the source system and the target AWS system, facilitating a smooth switch-over with minimal disruption. Performing a system export/import using SAP Software Provisioning Manager for SAP Solution Manager, and reinstalling SAP Web Dispatcher on AWS with the necessary configuration, addresses the other migration requirements comprehensively.
A company is running an SAP on Oracle system on IBM Power architecture in an on-premises data center. The company wants to migrate the SAP system to AWS. The Oracle database is 15 TB in size. The company has set up a 100 Gbps AWS Direct Connect connection to AWS from the on-premises data center.
Which solution should the company use to migrate the SAP system MOST quickly?
To migrate the SAP system most quickly, the company should use Cross Platform Transportable Tablespace (XTTS) conversion on the Oracle database. This method involves creating a staging Oracle database on premises to perform the XTTS conversion, taking a backup of the converted staging database, and copying it to AWS through the Direct Connect connection. Regularly scheduled incremental backups and XTTS conversions of the staging database should also be taken and transferred to AWS. During the migration window, a final incremental Oracle backup should be performed, converted using XTTS, and the logs replayed in the target Oracle database hosted on AWS. This approach allows for a smooth and efficient migration with minimal downtime, making it the quickest solution.
