Question #15

A global company is planning to migrate its SAP S/4HANA workloads and SAP BW/4HANA workloads to AWS. The company's database will not grow more than 3 TB for the next 3 years.
The company's production SAP HANA system has been designed for high availability (HA) and disaster recovery (DR) with the following configurations:
- HA: SAP HANA system replication configured with SYNC mode and
LOGREPLAY operation mode across two Availability Zones with the same
size SAP HANA node
- DR: SAP HANA system replication configured with ASYNC mode and
LOGREPLAY operation mode across AWS Regions with the same size SAP HANA node All the SAP HANA nodes in the current configuration are the same size. For HA, the company wants an RPO of 0 and an RTO of 5 minutes. For DR, the company wants an RPO of 0 and an RTO of 3 hours.
How should the company design this solution to meet the RPO and RTO requirements MOST cost-effectively?

A. Maintain HA with SAP HANA system replication across two Availability Zones. Decrease the size of the HA secondary node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with SYNC mode and table preload turned on. Increase the size of the HA secondary node during an HA event. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with table preload turned off.Increase the size of the DR node during a DR event.

B. Maintain HA with SAP HANA system replication configured with SYNC mode and table preload turned on across two Availability Zones. In each Availability Zone, use the same size SAP HANA node. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with ASYNC mode and table preload turned on. Increase the size of the DR node during a DR event.

C. Maintain HA with SAP HANA system replication configured with SYNC mode and table preload turned on across two Availability Zones. In each Availability Zone, use the same size SAP HANA node. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with ASYNC mode and table preload turned off. Increase the size of the DR node during a DR event.

D. Maintain HA with SAP HANA system replication across two Availability Zones. Decrease the size of the HA secondary node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with SYNC mode and table preload turned on. Increase the size of the HA secondary node during an HA event. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with table preload turned on.
Increase the size of the DR node during a DR event.

Question #16

An SAP solutions architect is leading the SAP basis team for a company. The company's SAP landscape includes SAP HANA database instances for the following systems: sandbox, development, quality assurance test (QAT), system performance test (SPT), and production. The sandbox, development, and QAT systems are running on Amazon EC2 On-Demand Instances.
The SPT and production systems are running on EC2 Reserved instances. All the EC2 instances are using Provisioned IOPS SSO (io2) Amazon Elastic Block Store (Amazon EBS) volumes.
The entire development team is in the same time zone and works from 8 AM to 6 PM. The sandbox system is for research and testing that are not critical. The SPT and production systems are business critical. The company runs load-testing jobs and stress-testing jobs on the QAT systems overnight to reduce testing duration. The company wants to optimize infrastructure cost for the existing AWS resources.
How can the SAP solutions architect meet these requirements with the LEAST amount of administrative effort?

A. Use a Spot Fleet instead of the Reserved Instances and On-Demand Instances.

B. Use Amazon EventBridge (Amazon CloudWatch Events) and Amazon CloudWatch alarms to stop the development and sandbox EC2 instances from 7 PM every night to 7 AM the next day.

C. Make the SAP basis team available 24 hours a day, 7 days a week to use the AWS CLI to stop and start the development and sandbox EC2 instances manually.

D. Change the EBS volume type to Throughput Optimized HDD (st1) for the /hana/data and /hana/log file systems for the production and non-production SAP HANA databases.

Question #17

A company has implemented its ERP system on SAP S/4HANAon AWS. The system is based on Enqueue Standalone Architecture (ENSA2) and is highly available.
As part of an availability test, the company failed over its system to secondary nodes in the second Availability Zone. When the system failed over, the initial licenses were no longer valid.
What could be the reason for this behavior?

A. The cluster configuration is not correct.

B. The company needs to apply SAP licenses after each failover.

C. The company needs two separate sets of licenses for ASCS instances in each Availability Zone.

D. The company stopped and restarted the secondary node as part of the last maintenance.

Question #18

A company runs its SAP ERP 6.0 EHP 8 system on SAP HANA on AWS. The system is deployed on an r4.16xlarge Amazon EC2 instance with default tenancy. The company needs to migrate the SAP HANA database to an x2gd.16xlarge High Memory instance. After an operations engineer changes the instance type and starts the instance, the AWS Management Console shows a failed instance status check.
What is the cause of this problem?

A. The operations engineer missed the Amazon CloudWatch configuration step during the post- migration activities.

B. The operations engineer did not install Elastic Network Adapter (ENA) drivers before changing the instance type.

C. The operations engineer missed the network configuration step during the post-migration activities.

D. The operations engineer did not create a new AMI from the original instance and did not launch a new instance with dedicated tenancy from the AMI.

Question #19

An SAP engineer has deployed an SAP S/4HANA system on an Amazon EC2 instance that runs Linux. The SAP license key has been installed. After a while, the newly installed SAP instance presents an error that indicates that the SAP license key is not valid because the SAP system's hardware key changed. There have been no changes to the EC2 instance or its configuration.
Which solution will permanently resolve this issue?

A. Reboot the EC2 instance.

B. Apply a new SAP license that uses a new hardware key. Install the new key.

C. Set the SLIC_HW_VERSION Linux environment variable.

D. Perform SAP kernel patching.

Question #20

A company has been using a third-party backup tool that uses backint for data protection of SAP HANA on AWS. Because of cost and the effort that is required to maintain the dedicated backup server, the company is considering the use of AWS Backint Agent for SAP HANA.
The SAP HANA system uses General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volumes for the SAP HANA data volumes and log volumes. Backup files are stored in an Amazon S3 bucket. An SAP solutions architect is setting up a proof-of-concept deployment for this new environment and needs to improve the speed of the database backup and restore procedures.
Which solutions will meet these requirements? (Choose two.)

A. Adjust the number of parallel backup channels by increasing the value of the parallel_data_backup_backint_channels SAP HANA parameter.

B. Check how much storage throughput is available to the SAP HANA EBS data volumes (/hana/data).
Modify the SAP HANA EBS data volumes to a Provisioned IOPS SSD volume type, and try the backup again.

C. Use S3 Transfer Acceleration to configure transfer of backup files.

D. Enable deduplication for the backup files.

E. Increase the S3 bucket size. Ensure that access to the S3 bucket comes from an Amazon EC2 instance in the same AWS Region.

Question #21

A company is migrating a 20 TB SAP S/4HANA system to AWS. The company wants continuous monitoring of the SAP S/4HANA system and wants to receive notification when CPU utilization is greater than 90%. An SAP solutions architect must implement a solution that provides this notification with the least possible effort.
Which solution meets these requirements?

A. Use the Amazon CloudWatch dashboard to monitor CPU utilization. Set up an Amazon Simple Notification Service (Amazon SNS) topic to send the notification.

B. Create an AWS Lambda function that checks CPU utilization and sends the notification.

C. Use Amazon CloudWatch to set a CPU utilization alarm. Set up an Amazon Simple Notification Service (Amazon SNS) topic to send the notification.

D. Use AWS CloudTrail to check the CPU utilization metric. Set up an Amazon Simple Notification Service (Amazon SNS) topic to send the notification.
