Question 1

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?

AWrite 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

BInstall 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

COrder an AWS Snowcone device Use the Snowcone device to transfer data between the on-premises servers and AWS

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

Answer : B

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.

Question 2

Business users are reporting timeouts during periods of peak query activity on an enterprise SAP HANAdata mart An SAP system administrator has discovered that at peak volume the CPU utilization increases rapidly to 100% for extended periods on the x1.32xlarge Amazon EC2 instance where the database is installed However the SAP HANA database is occupying only 1 120 GiB of the available 1 952 GiB on the instance 10 wart times are not increasing Extensive query tuning and system tuning have not resolved this performance problem

Which solutions should the SAP system administrator use to improve the performance? (Select TWO.)

AReduce the global_allocation_limit parameter to i 120 GiB

BMigrate the SAP HANA database to an EC2 High Memory instance with a larger number of available vCPUs

CMove to a scale-out architecture for SAP HANA with at least three x1 16xlarge instances

DModify the Amazon Elastic Block Store (Amazon EBS) volume type from General Purpose to Provisioned lOPS for ail SAP HANA data volumes

EChange to a supported compute optimized instance type for SAP HANA

Answer : C, E

Question 3

A company is running SAP ERP Central Component (SAP ECC) with a Microsoft SQL Server database on AWS A solutions architect must attach an additional 1 TB Amazon Elastic Block Store (Amazon EBS) volume. The company needs to write the SQL Server database backups to this EBS volume before moving the database backups to Amazon S3 for long-term storage.

Which EBS volume type will meet these requirements MOST cost-effectively?

AThroughput Optimized HDD (st1)

BProvisioned IOPS SSD (io3)

CGeneral Purpose SSD (gp3)

DCold HDD (sc1)

Answer : A

'For SQL Server database backup, you can use one of the following methods: SQL native tools to take backup on disk: Backup requires high throughput compared to IOPS. We recommend using Throughput Optimized HDD (st1) which provides maximum throughput of 500 MB/s per volume.'

Question 4

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?

AReboot the instance to initiate instance migration to another host

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

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

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

Answer : D

D is correct because installing the missing drivers on the source system is required to support the R5 instance family. The source system must have the ENA and NVMe drivers installed before launching the test instance. The other options are not relevant for solving the problem and may not resolve the instance status check failure.

Question 5

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 OAT 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 (K)2) Amazon Elastic Block Store (Amazon EBS) volumes.

The entire development learn 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?

AUse a Spot Fleet instead of the Reserved Instances and On-Demand Instances

BUse 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

CMake 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

DChange the EBS volume type to Throughput Optimized HDD (sti) for the /hana/data and nana, log file systems for the production and non-production SAP HANA databases

Answer : B

B is correct because using 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 reduces the infrastructure cost for the non-critical systems that are not used during that time. This solution also requires the least amount of administrative effort as it is automated and does not require manual intervention.

Question 6

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.)

ACreate a cluster placement group Launch the instances into the cluster placement group

BCreate a spread placement group Launch the instances into the spread placement group

CCreate a partition placement group Launch the instances into the partition placement group

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

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

Answer : A, D

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.

Question 7

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 n 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?

ABefore the migration window build a new installation of the SAP system on AWS by using SAP Software Provisioning Manager. During the migration window export a
copy of the SAP system and database by using the heterogeneous system copy process and R3load Copy the output of the SAP system files to AWS through the Direct Connect connection import the SAP system to the new SAP installation on AWS Switch over to the SAP system on AWS

BBefore the migration window build a new installation of the SAP system on AWS by using SAP Software Provisioning Manager Back up the Oracle database by using native Oracle tools Copy the backup of the Oracle database to AWS through the Direct Connect connection Import the Oracle database to me SAP system on AWS Configure Oracle Data Guard to begin replication on-premises database log changes from the SAP system to the new AWS system During the migration window use Oracle to replicate any remaining changes to the Oracle database hosted on AWS Switch over to the SAP system on AWS

CBefore the migration window build a new installation of the SAP system on AWS by using SAP Software Provisioning Manager Create a staging Oracle database on premises to perform Cross Platform Transportable Tablespace (XTTS) conversion on the Oracle database Take a backup of the convened staging database Copy the converted backup to AWS through the Direct Connect connection import the Oracle database backup to the SAP system on AWS Take regularly scheduled incremental backups and XTTS conversions of the staging database Transfer these backups and conversions to the AWS target database During the migration window, perform a final incremental Oracle backup Convert the final Oracle backup by using XTTS Replay the logs in the target Oracle database hosted on AWS Switch over to the SAP system on AWS

DBefore the migration window launch an appropriately sized Amazon EC2 instance on AWS to receive the migrated SAP database Create an AWS Server Migration Service (AWS SMS) job to take regular snapshots of the on-premises Oracle hosts Use AWS SMS to copy the snapshot as an AMI to AWS through the Direct Connect connection Create a new SAP on Oracle system by using the migrated AMI During the migration window take a final incremental SMS snapshot and copy the snapshot to AWS Restart the SAP system by using the new up-to-date AMI Switch over to the SAP system on AWS

Answer : C

This solution uses the Cross Platform Transportable Tablespace (XTTS) feature of Oracle database to migrate the 15 TB Oracle database to AWS. By creating a staging Oracle database on-premises and performing the XTTS conversion on it, the company can create a backup of the database that can be imported directly into the SAP system on AWS. This eliminates the need to perform a full database export and import, which can be time-consuming for large databases. By taking regularly scheduled incremental backups and XTTS conversions of the staging database, the company can keep the AWS target database up-to-date with the on-premises database. During the migration window, a final incremental Oracle backup is taken and the logs are replayed in the target Oracle database hosted on AWS, minimizing downtime. Finally, the company can switch over to the SAP system on AWS.
