Amazon AWS Certified: SAP on AWS - Specialty 認定 PAS-C01 試験問題 (Q41-Q46):
質問 # 41 A company wants to improve the RPO and RTO for its SAP disaster recovery (DR) solution by running the DR solution on AWS The company is running SAP ERP Central Component (SAP ECO on SAP HANA The company has set an RPO of 15 minutes and an RTO of 4 hours. The production SAP HANA database is running on a physical appliance that has x86 architecture. The appliance has 1 TB of memory and the SAP HANA global allocation limit is set to 768 GB. The SAP application servers are running as VMs on VMware and they store data on an NFS file system The company does not want to change any existing SAP HANA parameters that are related to data and log backup for its on-premises systems. What should an SAP solutions architect do to meet the DR objectives MOST cost-effectively?
A. For the SAP HANA database use a smaller SAP certified Amazon EC2 instance Use SAP HANA system replication with ASYNC replication mode to replicate the data continuously from on premises to AWS For the SAP application servers use CloudEndure Disaster Recovery for continuous data replication For NFS file shares sapmnt and .'uv-sap'trans. establish real-time synchronization from AWS DataSync to Amazon Elastic File System (Amazon EFS)
B. For the SAP HANA database change the log backup frequency to 5 minutes Move the data and log backups to Amazon S3 by using AWS Storage Gateway File Gateway For the SAP application servers export the VMs as AMIs by using the VM Import'Export feature from AWS For NFS file shares /sapmnt and 'usr saplrans establish realtime synchronization from AWS DataSync to Amazon Elastic Foe System (Amazon EFS)
C. For the SAP HANA database change the log backup frequency to 5 minutes Move the data and log backups to Amazon S3 by using the AWS CLI or AWS DataSync Launch the SAP HANA database For the SAP application servers, export the VMs as AMis by using the VM import/Export feature from AWS For NFS file shares/sapmnt and usr-sap/trans/ establish real-time synchronization from DataSync to Amazon Elastic File System (Amazon EFS)
D. For the SAP HANA database SAP application servers and NFS Me shares use CloudEndure Disaster Recovery to replicate the data continuously from on premises to AWS Use CloudEndure Disaster Recovery to launch target instances in the event of a disaster
正解:B 質問 # 42 A company is migrating its SAP workloads to AWS The company's IT team installs a highly available SAP S.4HANA system that uses the SAP HANA system replication cluster package on SUSE Linux Enterprise Server The IT team deploys the system by using cluster nodes m different Availability Zones within the same AWS Region. After the initial launch of the SAP application the application is accessible However after failover the IT team cannot access the application even though the system is up and running on the secondary node After investigation an SAP solutions architect discovers that the virtual IP address has not been used correctly Which combination of steps should the SAP solutions architect take to resolve this problem? (Select TWO.)
A. Use an overlay IP address as a secondary IP address with the primary node of the cluster
B. Choose an overlay IP address within the VPC CiDR block that corresponds with the secondary node of the cluster
C. Use an overlay IP address as a virtual IP address
D. Choose an overlay IP address outside the VPC CiDR block that hosts the application and the database
E. Choose an overlay IP address within the VPC CIDR block that corresponds with the primary node of the cluster
正解:A、E 質問 # 43 A company is planning to migrate its on-premises SAP application to AWS. The application runs on VMware vSphere The SAP ERP Central Component (SAP ECC) server runs on an IBM Db2 database that is 2 TB m size The company wants to migrate the database to SAP HANA Which migration strategy will meet these requirements'?
A. Use AWS Application Migration Service (CloudEndure Migration)
B. Use AWS Server Migration Service (AWS SMS)
C. Use AWS Database Migration Service (AWS DMS)
D. Use SAP Software Update Manager (SUM) Database Migration Option (DMO) with System Move
正解:D
解説: Explanation The company can meet its requirements by adding an outbound rule to the network ACL of the subnet that contains the SAP PO system. This rule should allow the FQDN of the payroll SaaS provider and deny all other outbound traffic. This would restrict all outbound traffic to the payroll SaaS provider and ensure compliance with corporate security guidelines. AWS WAF web ACL is not appropriate for this use case as it's mainly used to protect web applications and does not provide the level of granularity required for this use case. AWS Network Firewall firewall is not appropriate for this use case as it's mainly used to protect VPCs from unwanted inbound traffic and does not provide the level of granularity required for this use case. 質問 # 44 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?
A. Before 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
B. Before 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
C. Before 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
D. Before 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
正解:D
解説: Explanation 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. 質問 # 45 A company is running SAP on anyDB at a remote location that has slow and inconsistent internet connectivity. The company wants to migrate its system to AWS and wants to convert its database to SAP HANA during this process Because of the inconsistent internet connection the company has not established connectivity between the remote location and the company's VPC in the AWS Cloud. How should the company perform this migration?
A. Migrate by using SAP Software Update Manager (SUM) Database Migration Option (DMO) with System Move Use Amazon Elastic File System (Amazon EPS) to transfer the SAP export files to AWS
B. Migrate by using SAP Software Update Manager (SUM) Database Migration Option (DMO) with System Move Use an AWS Snowball Edge Storage Optimized device to transfer the SAP export files to AWS
C. Migrate by using SAP HANA system replication over the internet connection Specify a public IP address on the target system
D. Migrate by using SAP HANA system replication with initialization through backup and restore Use an AWS Snowball Edge Storage Optimized device to transfer the SAP export files to AWS
正解:B
解説: Explanation Snowball Edge allows for offline data transfer, which is suitable for cases where there is slow and inconsistent internet connectivity. The data can be transferred to the Snowball Edge device, shipped to the AWS region, and then imported into the new SAP HANA system in the VPC. This is a suitable option for migrating large amounts of data from a remote location to AWS. 質問 # 46 ......
