Question 1

A company is running an SAP ERP Central Component (SAP ECC) system on an SAP HANA database that is 10 TB m size The company rs 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'?

AEnsure mat AWS Backint agent is configured to send the backups to an Amazon S3 bucket over the internet Ensure that the EC2 instance is configured to access the internet through a NAT gateway

BCheck the UploadChanneiSize parameter for AWS Backint agent increase this value in the aws-backint-agent-config yaml configuration file based on the EC2 instance type and storage configurations

CCheck the MaximumConcurrentFilesForRestore parameter tor AWS Backint agent Increase the parameter from 5 to 10 by using the aws-backint-agent-config yaml configuration file

DEnsure that the backups are compressed if necessary configure AWS Backint agent to compress the backups and send them to an Amazon S3 bucket

Answer : B

The problem is long-running database backups every day, it is likely that the backups are taking too long to complete because the upload channel size is not sufficient for the size of the backups. By increasing the UploadChannelSize parameter, the SAP NetWeaver administrator can adjust the amount of data that is sent over the network at a time, which can help to speed up the backups and reduce the time they take to complete. This can be done by editing the aws-backint-agent-config yaml configuration file and increasing the value of the UploadChannelSize parameter based on the EC2 instance type and storage configurations.

Question 2

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?

ACreate a new resource-based policy that prevents deletion of the S3 bucket

BEnable versioning and multi-factor authentication (MFA) on the S3 bucket

CCreate signed cookies for the backup files in the S3 bucket Provide the signed cookies to authorized users only

DApply an S3 Lifecycle policy to move the backup fries immediately to S3 Glacier

Answer : B

enabling versioning and multi-factor authentication (MFA) on the S3 bucket. Versioning will allow you to keep multiple versions of your backup files in the same bucket, so you won't have to worry about accidental deletion. Multi-factor authentication (MFA) will help ensure that only authorized users can access or delete the backup files.

Question 3

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 4

A global retail company is running its SAP landscape on AWS Recently the company made changes to its SAP Web Dispatcher architecture The company added an additional SAP Web Dispatcher for high availability with an Application Load Balancer (ALB) to balance the load between the two SAP Web Dispatchers

When users try to access SAP through the ALB the system is reachable However the SAP backend system is showing an error message An investigation reveals that the issue is related to SAP session handling and distribution of requests . The company confirmed that the system was working as expected with one SAP Web Dispatcher. The company replicated the configuration of that SAP Web Dispatcher to the new SAP Web Dispatcher

How can the company resolve the error?

AMaintain persistence by using session cookies Enable session stickiness (session affinity) on the SAP Web Dispatchers by setting the wdisp/HTTP/esid_support parameter to True

BMaintain persistence by using session cookies Enable session stickiness (session affinity) on the ALB

CTurn on host-based routing on the ALB to route traffic between the SAP Web Dispatchers

DTurn on URL-based routing on the ALB to route traffic to the application based on URL

Answer : A

The error message being displayed is related to SAP session handling and distribution of requests. By using session cookies, the company can maintain persistence of the user's session across requests. By enabling session stickiness on the SAP Web Dispatchers by setting the wdisp/HTTP/esid_support parameter to True, the company can ensure that requests from the same user are always routed to the same SAP Web Dispatcher. This would resolve the error message that the company is seeing and ensure that the backend system is working as expected with the new SAP Web Dispatcher configuration.

Question 5

A company is running its SAP workloads on premises and needs to migrate the workloads to AWS All the workloads are running on SUSE Linux Enterprise Server and Oracle Database. The company's landscape consists of SAP ERP Central Component {SAP ECC). SAP Business Warehouse (SAP BW), and SAP NetWeaver systems. The company has a dedicated AWS Direct Connect connection between its on-premises environment and AWS The company needs to migrate the systems to AWS with the least possible downtime

Which migration solution will meet these requirements?

AUse SAP Software Provisioning Manager to perform an export of the systems Copy the export to Amazon S3 Use SAP Software Provisioning Manager to perform an import of the systems to SUSE Linux Enterprise Server and Oracle Database on AWS

BUse SAP Software Provisioning Manager to perform parallel export import of the systems to migrate the systems to SUSE Linux Enterprise Server and Oracle Database on AWS

CUse SAP Software Provisioning Manager to perform parallel export/import of the systems to migrate the systems to Oracle Enterprise Linux and Oracle Database on AWS

DUse SAP Software Provisioning Manager to perform an export of the systems Copy the export to Amazon S3 Use SAP Software Provisioning Manager to perform an import of the systems to Oracle Enterprise Linux and Oracle Database on AWS.

Answer : C

It is mandatory to have Oracle Enterprise Linux(OEL) as the operating system for running Oracle database for SAP. https://launchpad.support.sap.com/#/notes/1656250

Question 6

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.

Question 7

A company's basis administrator is planning to deploy SAP on AWS m Linux. The basis administrator must set up the proper storage to store SAP HANA data and log volumes. Which storage options should the basis administrator choose to meet these requirements? (Select TWO.)

AAmazon Elastic Block Store (Amazon EBS) Throughput Optimized HDD (st1)

BAmazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD (io1, k>2)

CAmazon S3

DAmazon Elastic File System (Amazon EFS)

EAmazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp2 gp3)

Answer : B, E

Amazon Elastic Block Store (EBS) Provisioned IOPS SSD (io1) provides high IOPS, low latency, and high throughput, making it ideal for use as a storage option for SAP HANA data and log volumes. It is designed for I/O-intensive workloads and is recommended for SAP HANA. Amazon Elastic Block Store (EBS) General Purpose SSD (gp2, gp3) is also a good choice for SAP HANA data and log storage, it provides a balance of performance and cost, with a low latency and high throughput. Amazon S3 is an object storage service and not suitable for storing the SAP HANA data and log volumes. Amazon Elastic File System (Amazon EFS) is a file storage service, it's not a good fit for block-based storage workloads like SAP HANA. https://docs.aws.amazon.com/sap/latest/sap-hana/hana-ops-storage-config.html
