PAS-C01 Migration Practice Test 29 — 15 Questions

Question 1

A company is migrating an SAP ERP system to AWS and needs to ensure that the SAP application servers can scale automatically based on CPU utilization. Which AWS service should be used to achieve this?

Accepted Answer

AWS Auto Scaling. AWS Auto Scaling can automatically adjust the number of EC2 instances based on CloudWatch alarms for CPU utilization, making it suitable for scaling SAP application servers. Option A is wrong because Elastic Load Balancing distributes traffic but does not scale instances. Option B is wrong because AWS Lambda is for serverless compute, not for running SAP application servers. Option C is wrong because AWS CloudFormation is an infrastructure-as-code service, not for automatic scaling.

Answer

AWS Elastic Load Balancing (ELB)

Answer

AWS Lambda

Answer

AWS CloudFormation

Question 2

A company is migrating SAP HANA to AWS and needs to ensure high availability. The database must be replicated synchronously across two Availability Zones with automatic failover. Which AWS service should be used?

Accepted Answer

SAP HANA System Replication (HSR) with Pacemaker. SAP HANA System Replication (HSR) with Pacemaker provides synchronous replication and automatic failover, making it the appropriate solution for high availability across Availability Zones. Amazon EBS Multi-Attach is incorrect because it is limited to a single AZ and not designed for SAP HANA replication. AWS DMS is for database migration, not ongoing HA. Amazon RDS Multi-AZ is for RDS databases and does not support SAP HANA.

Answer

Amazon EBS Multi-Attach volumes

Answer

AWS Database Migration Service (DMS)

Answer

Amazon RDS Multi-AZ deployment

Question 3

A company is migrating an SAP Business Warehouse (BW) system running on an on-premises HANA database to AWS. The migration must be completed with less than 1 hour of downtime. The source database is 3 TB. The company has established a 10 Gbps AWS Direct Connect connection. The SAP system uses a custom ABAP program that must be migrated as well. The company wants to minimize manual intervention. Which approach should be taken?

Accepted Answer

Set up SAP HANA System Replication (HSR) to replicate the database to AWS, then perform a takeover.. SAP HANA System Replication (HSR) continuously replicates the HANA database from on-premises to an AWS-hosted HANA instance over the 10 Gbps Direct Connect link, keeping the target in sync. A planned takeover during cutover achieves sub-hour downtime because the secondary is already current, and the custom ABAP program travels with the SAP system as part of the application server migration. This is the standard SAP-certified approach for near-zero-downtime HANA migrations.

Answer

Use AWS DMS to replicate the HANA database to Amazon RDS for HANA.

Answer

Export the HANA database to files, transfer via Direct Connect, and import on EC2.

Answer

Use AWS Application Migration Service (MGN) to replicate the entire server.

Question 4

A company is migrating an SAP Business Suite system on Oracle to SAP S/4HANA on AWS. The migration involves a near-zero downtime requirement. The current system uses SAP Oracle on Linux. Which combination of tools should the company use?

Accepted Answer

Use SAP Software Update Manager (SUM) with the Database Migration Option (DMO) and the near-zero downtime option.. SAP Software Update Manager (SUM) with the Database Migration Option (DMO) and the near-zero downtime option is the SAP-recommended approach for migrating SAP Business Suite on Oracle to SAP S/4HANA on AWS with minimal downtime. DMO combines the SAP upgrade and database migration into a single run, and the near-zero downtime option uses SAP's downtime-optimized migration to reduce cutover time.

Answer

Use AWS Schema Conversion Tool (AWS SCT) and AWS Database Migration Service (AWS DMS) with ongoing replication.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the Oracle database to Amazon RDS for SAP HANA.

Answer

Use SAP Landscape Transformation (SLT) to replicate data to SAP HANA, then switch applications.

Question 5

A company needs to migrate its SAP application server from on-premises to AWS. The server runs on Windows Server 2012 R2 and has a custom SAP kernel. Which AWS service should be used to migrate the server with minimal changes?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) is the recommended service for lift-and-shift rehosting of physical, virtual, or cloud servers to AWS with minimal changes. It supports Windows Server 2012 R2 and custom SAP kernels by replicating the entire server block-level to AWS and launching it as an EC2 instance, preserving the OS, applications, and custom kernel. This makes it the correct choice for a minimal-change migration.

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Server Migration Service (AWS SMS)

Question 6

A company is migrating its SAP system from on-premises to AWS. The system uses a shared filesystem (NFS) for transport directories and logs. The company wants to use AWS storage services to provide a similar shared filesystem. Which storage solution is MOST appropriate for this migration?

Accepted Answer

Amazon EFS (Elastic File System). Amazon EFS is a fully managed, scalable, shared NFS file system designed for Linux workloads, making it the most appropriate choice for SAP transport directories and logs that require a shared filesystem. It supports NFSv4 and can be mounted on multiple EC2 instances simultaneously, providing the shared storage needed for SAP.

Answer

Amazon S3 with a mount point via s3fs-fuse

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with multi-attach enabled

Question 7

A company is migrating an SAP environment to AWS and wants to automate the provisioning of infrastructure using code. Which AWS service should be used for this purpose?

Accepted Answer

AWS CloudFormation. AWS CloudFormation enables infrastructure as code (IaC) to provision and manage AWS resources in a repeatable and automated manner, which is ideal for automating SAP environment provisioning. Option A (AWS Elastic Beanstalk) is incorrect because it is a platform-as-a-service (PaaS) for deploying and scaling web applications, not for provisioning general infrastructure. Option B (AWS CloudFormation) is correct because it directly provides infrastructure as code. Option C (AWS CodeDeploy) is incorrect because it automates application deployments to compute services, not infrastructure provisioning. Option D (AWS OpsWorks) is incorrect because it is a configuration management service using Chef/Puppet, not a direct infrastructure provisioning service like CloudFormation.

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Answer

AWS OpsWorks

Question 8

Which THREE factors are essential when planning the migration of an SAP system with near-zero downtime requirements? (Choose three.)

Accepted Answer

Network bandwidth between source and target. Option A (Network bandwidth between source and target) is essential because near-zero downtime migrations rely on transferring the bulk of data ahead of cutover and then replicating ongoing changes; insufficient bandwidth would make it impossible to keep the delta small enough to finish within the cutover window. Option B (Data volume and change rate during migration) is essential because the total data size determines the initial copy duration while the change rate determines how fast the delta grows, directly affecting whether the final synchronization can complete in the allowed downtime. Option D (Ability to perform a final delta sync before cutover) is essential because near-zero downtime is achieved by copying the bulk in advance and then applying only the accumulated changes during a short cutover, so a reliable final delta sync mechanism is mandatory. Option C is not among the marked correct answers: while performance testing is good practice, it is a validation activity rather than a factor that determines whether near-zero downtime is achievable. Option E is also not marked correct: storage type selection (EBS vs. EFS) is an architectural design decision, not a determining factor for meeting near-zero downtime requirements in the migration plan.

Answer

Performance testing strategy for the target system

Answer

Choice of storage type (EBS vs. EFS)

Question 9

A company is migrating a 3 TB SAP ERP system running on Oracle on AIX to SAP HANA on AWS. The system has a complex landscape with multiple application servers and a central Oracle database. The migration must be completed within a 4-day window with minimal downtime. The company has a 1 Gbps AWS Direct Connect connection. The SAP system is heavily customized with many ABAP programs and custom database objects. The migration team plans to use SAP Software Update Manager (SUM) with the Database Migration Option (DMO). During the migration rehearsal, the SUM DMO process fails during the database migration phase with an error indicating that the source database character set is not supported by the target SAP HANA. The source Oracle database uses the WE8ISO8859P1 character set. The team needs to resolve this issue before the final migration. Which course of action should the team take?

Accepted Answer

Convert the source Oracle database character set to UTF-8 (AL32UTF8) before starting the SUM DMO migration.. SAP HANA only supports UTF-8 character encoding. Therefore, the source Oracle database must be converted to UTF-8 (AL32UTF8) before using SUM DMO. Option A is incorrect because SAP HANA Studio migration tools cannot convert an unsupported character set during migration; they also require the source data to be UTF-8. Option B is incorrect because AWS Database Migration Service (AWS DMS) does not support SAP HANA as a target for SAP system migrations and cannot handle the necessary SAP-specific objects and customizations. Option D is incorrect because you cannot modify SAP HANA database parameters to support WE8ISO8859P1; HANA only works with UTF-8.

Answer

Use SAP HANA Studio migration tools to convert the character set during migration without changing the source.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the data and automatically convert the character set.

Answer

Change the target SAP HANA database to use the WE8ISO8859P1 character set by modifying the HANA database parameters.

Question 10

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service or feature should they use?

Accepted Answer

AWS Database Migration Service (AWS DMS) with ongoing replication. AWS DMS with ongoing replication performs a full load followed by continuous change data capture (CDC), keeping the target RDS for Oracle in sync with the source until cutover. This minimizes downtime because the application can be switched over after replication lag is near zero. It also ensures data consistency by applying ongoing changes in order.

Answer

RDS Read Replica

Answer

VPC Peering

Answer

AWS Schema Conversion Tool (AWS SCT)

Question 11

A company is moving their SAP Business One application from an on-premises data center to AWS. The application runs on Windows Server and uses Microsoft SQL Server. They want to use Amazon EC2 for the application and Amazon RDS for SQL Server for the database. They have already used AWS SCT to assess the database schema and found that it is compatible. What should they do next to migrate the database with minimal downtime?

Accepted Answer

Use AWS DMS to perform a full load and then enable ongoing replication. Option C is correct because AWS DMS can perform a full load of the existing SQL Server database into Amazon RDS for SQL Server and then enable ongoing replication (change data capture) to keep the target synchronized, allowing the cutover to happen with minimal downtime. Since the schema is already assessed as compatible, no schema conversion is needed, so DMS alone handles both the initial data copy and continuous changes. Option A is wrong because exporting to flat files and importing via S3 is a manual, offline process that cannot keep the target in sync and would require significant downtime. Option B is wrong because AWS SCT is unnecessary here—the schema is already compatible—and adding SCT conversion does not address continuous replication. Option D is wrong because a native backup/restore to RDS is a one-time operation that does not provide ongoing replication, so changes made after the backup would be lost or require downtime to reconcile.

Answer

Export the database to flat files and upload to S3, then import into RDS

Answer

Use AWS SCT to convert the schema and then use AWS DMS

Answer

Take a full backup of the on-premises SQL Server, upload it to Amazon S3, and restore to RDS

Question 12

A company is migrating their SAP S/4HANA system to AWS. They plan to use SAP HANA Cockpit for migration. During the pre-migration assessment, they find that the on-premises HANA system uses a mix of row and column store tables. The target AWS HANA instance is provisioned on a memory-optimized instance. They want to ensure optimal performance post-migration. Which additional step should they take?

Accepted Answer

Convert row store tables to column store tables where possible. Converting row store tables to column store improves performance for analytical workloads, which is typical for S/4HANA. Option A is wrong because reducing memory allocation could degrade performance. Option B is wrong because disabling compression would increase storage and memory usage. Option D is wrong because increasing parallelism may not help if the storage layout is suboptimal.

Answer

Reduce the memory allocation of the HANA instance

Answer

Disable data compression on the target HANA instance

Answer

Increase the number of HANA index servers

Question 13

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a 24-hour maintenance window. The migration must minimize downtime and support ongoing replication during the cutover. Which AWS service should be used for the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is purpose-built for migrating relational databases like Oracle to Amazon RDS with minimal downtime. It supports ongoing change data capture (CDC) replication from the source Oracle database to the target RDS instance, allowing the cutover to happen quickly once the initial full load is complete. This directly satisfies the requirement to minimize downtime and support ongoing replication during cutover.

Question 14

A company is migrating its SAP NetWeaver application servers from on-premises to AWS. The SAP database will remain on-premises temporarily. The migration team needs to reduce the amount of data transferred over the internet during the initial data copy and ensure that the application servers can communicate with the on-premises database with low latency and consistent performance. Which AWS service should be used to establish the network connection?

Accepted Answer

AWS Direct Connect. AWS Direct Connect offers a dedicated private connection that delivers consistent low latency and high bandwidth, which is critical for SAP application servers accessing an on-premises database during a phased migration. It also reduces data transfer over the public internet. Other options either lack the dedicated nature or are not designed for hybrid connectivity.

Answer

AWS Site-to-Site VPN

Answer

AWS Global Accelerator

Answer

AWS Transit Gateway

Question 15

A company is migrating its SAP NetWeaver ABAP stack to AWS using a homogeneous system copy. The source system runs on an on-premises server with HP-UX and an Oracle database. The target will use Amazon EC2 with SUSE Linux and SAP HANA. The migration team must determine the appropriate method. Which migration approach should they use?

Accepted Answer

Perform a heterogeneous system copy using the SAP Software Provisioning Manager with the 'Target Database' option set to SAP HANA.. The migration involves changing both the operating system (HP-UX to Linux) and the database (Oracle to SAP HANA). This qualifies as a heterogeneous system copy, which SAP supports through Software Provisioning Manager. The tool handles the data conversion and platform-specific adjustments required for SAP HANA on AWS. Other options either do not support the required changes or are not SAP-recommended.

Answer

Export the SAP system using SAP data extraction tools, create a new SAP system on AWS with SAP HANA, and manually reapply all customizations and data.

Answer

Perform a homogeneous system copy using a backup and restore of the Oracle database, then convert the database to SAP HANA using the SAP HANA database migration option.

Answer

Use AWS Application Migration Service (MGN) to replicate the on-premises server to AWS, then change the operating system and database in place.
