AWS on SAP Exam Preparation

A company is moving to the AWS Cloud gradually. The company has multiple SAP landscapes on VMware The company already has sandbox development and QA systems on AWS The company's production system is still running on-premises. The company has 2 months to cut over the entre landscape to the AWS Cloud The company has adopted a hybrid architecture for the next 2 months and needs to synchronize its shared file systems between the landscapes These shared file systems include trans directory mounts, /software directory mounts, and third-party integration mounts in the on-premises landscape the company has NFS mounts between the servers On the AWS infrastructure side the company is using Amazon Elastic File System (Amazon EFS) to share the common files An SAP solutions architect needs to design a solution to schedule transfer of these shared files bidirectional four times each day. The data transfer must be encrypted Which solution will meet these requirements?

• Write an rsync script Schedule the script through cron for four times each day in the on-premises VMware servers to transfer the data from on premises to AWS

• Install an AWS DataSync agent on the on-premises VMware platform Use the DataSync endpoint to synchronize between the on-premises NFS server and Amazon EFS on AWS

• Order an AWS Snowcone device Use the Snowcone device to transfer data between the onpremises servers and AWS

• Set up a separate AWS Direct Connect connection for synchronization between the on-premises servers and AWS

Answer explanation

AWS DataSync can be used to schedule and automate the transfer of data between on-premises NFS servers and Amazon EFS on AWS. It also allows data to be encrypted during transfer, which meets the requirement for encryption.

Answer explanation

Ensures high availability and disaster recovery by using SAP HANA system replication in two different availability zones in eu-central-1, and then installing a third secondary system in eu-west-1 with SYNC replication mode, which provides a fallback option in case of disaster, also it meets the inter-AZ latency requirement. Ensures high availability and disaster recovery by using SAP HANA system replication in two different availability zones in eu-central-1, and then storing daily backups from tier 1 in an Amazon S3 bucket in eu-central-1 and then using S3 cross-region replication to copy the backups to eu-west-1 where they can be restored if needed, this meets the inter-region latency requirement.

A company that has SAP workloads on premises plans to migrate an SAP environment to AWS. The company is new to AWS and has no poor setup. The company has the following requirements - The application server and database server must be placed in isolated network configurations SAP systems must be accessible to the on-premises end users over the internet The cost of communications between the application server and the database server must be minimized Which combination of steps should an SAP solutions architect take to meet these requirements? (Select TWO.)

• Configure a Network Load Balancer for incoming connections from end users

• Set up an AWS Site-to-Site VPN connection between the company's on-premises network and AWS

• Separate the application server and the database server by using different VPCs

• Separate the application server and the database server by using different subnets and network security groups within the same VPC

• Set up an AWS Direct Connect connection with a private VIF between the company's on-premises network and AWS

Answer explanation

To meet the requirements, an SAP solutions architect should take the following steps: Separate the application server and the database server by using different VPCs. This will ensure that the application server and the database server are in isolated network configurations, and that the communication between them is minimized. Set up an AWS Direct Connect connection with a private VIF between the company's on-premises network and AWS. This will ensure that the SAP systems are accessible to the on-premises end users over the internet and minimize the cost of communications between the application server and the database server. Using a Network Load Balancer for incoming connections from end users is not a necessary step, as it's not required to meet the requirements Setting up an AWS Site-to-Site VPN connection is not a necessary step, as it's not required to meet the requirements Separating the application server and the database server by using different subnets and network security groups within the same VPC is not a necessary step as it's not required to meet the requirements

A company has an SAP Business One system that runs on SUSE Linux Enterprise Server 12 SP3. The company wants to migrate the system to AWS An SAP solutions architect selects a homogeneous migration strategy that uses AWS Application Migration Service (CloudEndure Migration) After the server migration process is finished the SAP solutions architect launches an Amazon EC2 test instance from the R5 instance family. After a few minutes the EC2 console reports that the test instance has failed an instance status check Network connections to the instance are refused How can the SAP solutions architect solve this problem?

• Reboot the instance to initiate instance migration to another host

• Request an instance limit increase for the AWS Region where the test instance is being launched

• Create a ticket for AWS Support that documents the test server instance ID Wait for AWS to update the host of the R5 instance

• Install the missing drivers on the source system Wait for the completion of migration synchronization Launch the test instance again

A company has moved an of its SAP workloads to AWS During peak business hours end users are reporting performance issues because work processes are going into PRIV mode on an SAP S/4HANA system An SAP support engineer indicates that SAP cannot provide support for this issue because some specific performance metrics are not available. Which combination of actions must the company perform to comply with SAP support requirements? (Select THREE.)

• Buy an SAP license from AWS Ensure that the SAP license is installed

• Select only an AWS Migration Acceleration Program (MAP) certified managed service provider (MSP)

• Enable detailed monitoring for Amazon CloudWatch on each Amazon EC2 instance where SAP workloads are running

• Install configure and run the AWS Data Provider for SAP on each Amazon EC2 instance where SAP workloads are running

An SAP solutions architect is designing an SAP HANA scale-out architecture for SAP Business Warehouse (SAP BW) on SAP HANA on AWS. The SAP solutions architect identifies the design as a three-node scale-out deployment of x1e 32xlarge Amazon EC2 instances The SAP solutions architect must ensure that the SAP HANA scale-out nodes can achieve the low-latency and high-throughput network performance that are necessary for node-to-node communication Which combination of steps should the SAP solutions architect take to meet these requirements? (Select TWO.)

• Create a cluster placement group Launch the instances into the cluster placement group

• Create a spread placement group Launch the instances into the spread placement group

• Create a partition placement group Launch the instances into the partition placement group

• Based on the operating system version verify that enhanced networking is enabled on all the nodes

• Switch to a different instance family that provides network throughput that is greater than 25 Gbps

Answer explanation

A cluster placement group is an Amazon EC2 feature that enables low-latency and high-throughput network performance for the instances that are launched into the group. This is achieved by placing the instances in the same availability zone and physically close to each other, which reduces network latency and increases network throughput. Enhanced networking is a feature provided by AWS that enables higher network performance by using specialized network interfaces that support higher IOPS and throughput. To meet the requirement of low-latency and high-throughput network performance, it is necessary to check that enhanced networking is enabled on all the nodes, based on the operating system version.

An SAP engineer has deployed an SAP S/4HANA system on an Amazon EC2 instance mat runs Linux. The SAP license key has been installed After a white 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?

• Perform SAP kernel patching

• Apply a new SAP license that uses a new hardware key Install the new key

• Set the SUC_HW_VERSlON Linux environment variable

• Reboot the EC2 instance

Answer explanation

When the hardware key changes, the license key becomes invalid and it requires to install new license key that uses the new hardware key.

A company is planning to deploy a new SAP NetWeaverABAP system on AWS with an Oracle database that runs on an Amazon EC2 instance. The EC2 instance uses a Linux-based operating system. The company needs a database storage solution that provides flexibility to adjust the IOPS regardless of the allocated storage size. Which solution will meet these requirements MOST cost-effectively?

• General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volumes

• Amazon Elastic File System (Amazon EFS) Standard-Infrequent Access (Standard-IA) storage class

• Amazon FSx for Windows File Server

• Provisioned IOPS SSD (io2) Amazon Elastic Block Store (Amazon EBS) volumes

Answer explanation

Provisioned IOPS SSD (io2) Amazon Elastic Block Store (Amazon EBS) volumes would be the most cost-effective solution that meets the company's requirements. This storage type allows for the flexibility to adjust the IOPS regardless of the allocated storage size. It is designed for I/O-intensive workloads and provide high IOPS, low latency, and high throughput. Amazon Elastic File System (Amazon EFS) and Amazon FSx for Windows File Server are not suitable for this use case as they are file storage systems and not block storage systems. General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volumes is less performant and expensive than Provisioned IOPS SSD (io2) Amazon Elastic Block Store (Amazon EBS) volumes.

A company has deployed its SAP applications into multiple Availability Zones in the same AWS Region To accommodate storage of media files database table export and import and files dropped by third-party tools the company has mounted Amazon Elastic File System (Amazon EFS) file systems between the SAP instances The company needs to retrieve the files quickly for installations updates and system refreshes Over time the EFS file systems have grown exponentially to multiple terabytes An SAP solutions architect must optimize storage cost for the tiles that are stored in Amazon EFS. Which solution will meet this requirement with the LEAST administrative overhead?

• Scan the files manually to identify unnecessary file Delete the unnecessary files

• Move the files to Amazon S3 Glacier Deep Archive

• Apply a lifecycle policy on the files in Amazon EFS to move the files to EFS Standard-Infrequent Access (Standard-IA)

• Move the files to Amazon Glacier Apply an S3 Glacier vault lock policy to the files

Answer explanation

Apply a lifecycle policy on the files in Amazon EFS to move the files to EFS Standard-Infrequent Access (Standard-IA) is the solution that will meet this requirement with the least administrative overhead. This solution allows you to automatically move files that have not been accessed for a certain period of time to a lower-cost storage class, reducing storage costs without the need for manual intervention
