PAS-C01 Migration Practice Test 13 — 15 Questions

Question 1

A global company is migrating its SAP ERP system to AWS. The system runs SAP ECC on IBM AIX with Oracle Database. The company plans to move to SAP S/4HANA on AWS. The source system is 5 TB in size. The network bandwidth between the on-premises data center and AWS is 100 Mbps. The migration must be completed within a 2-week window with minimal downtime. The company has a SAP license that allows running S/4HANA on certified hardware. They have already used AWS SCT to convert the database schema to SAP HANA-compatible format. They now need to execute the data migration. The team is considering the following options:

Option A: Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover.
Option B: Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA.
Option C: Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA.
Option D: Use SAP HANA system replication from the source Oracle database to the target HANA database.

Which option is the most feasible and efficient for this migration?

Accepted Answer

Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover. The most feasible because AWS DMS supports heterogeneous migrations from Oracle to SAP HANA, and the ongoing replication capability minimizes downtime during the cutover. Option A (SAP HANA system replication) is incorrect because it requires the source database to already be SAP HANA, not Oracle. Option B (Snowball Edge) is inefficient for this scenario because restoring from backup files does not provide ongoing replication, and the 2-week window with minimal downtime would be difficult to achieve. Option C (DataSync to EFS) is designed for file transfers, not database migration, and importing into HANA would require additional complex steps. The schema conversion has already been done with AWS SCT, so DMS can handle the data migration efficiently.

Answer

Use SAP HANA system replication from the source Oracle database to the target HANA database

Answer

Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA

Answer

Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA

Question 2

A company is migrating an SAP HANA database to AWS. The database is 2 TB in size and runs on a single server. The company needs to minimize downtime during the migration. Which AWS service should be used for the initial data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is a physical device designed for large-scale data transfer, allowing the 2 TB SAP HANA database to be shipped to AWS, bypassing network limitations and minimizing downtime. Option B is incorrect because AWS DMS with ongoing replication is intended for continuous synchronization after initial load, not for the initial bulk transfer, and still relies on network speed. Option C is incorrect because AWS Direct Connect provides a dedicated network connection but does not eliminate transfer time for large datasets like 2 TB. Option D is incorrect because Amazon S3 Transfer Acceleration speeds up uploads over the public internet, but for 2 TB, network transfer would still be slower and less predictable than a physical device.

Answer

AWS Database Migration Service (DMS) with ongoing replication

Answer

AWS Direct Connect

Answer

Amazon S3 Transfer Acceleration

Question 3

An SAP system on AWS is experiencing high latency between the SAP application servers and the HANA database. The application servers are in a different Availability Zone than the database. Which change should a migration specialist recommend to reduce latency without increasing costs significantly?

Accepted Answer

Deploy SAP application servers in the same placement group and Availability Zone as the HANA database. Deploying SAP application servers in the same placement group and Availability Zone as the HANA database minimizes network distance and reduces latency without additional cost. Option A is incorrect: Enhanced Networking improves throughput and reduces packet loss but does not eliminate cross-AZ latency. Option B is incorrect: VPC Peering is used for inter-VPC connectivity, not for reducing latency within the same VPC. Option C is incorrect: using larger instance types does not necessarily reduce network latency and would increase costs.

Answer

Enable Enhanced Networking on all instances

Answer

Create a VPC Peering connection between the application and database subnets

Answer

Use larger instance types for the application servers

Question 4

A company is migrating an SAP NetWeaver system to AWS. The system uses SAProuter for secure network communication. What is the recommended approach to preserve the SAProuter functionality during the migration?

Accepted Answer

Deploy SAProuter on an EC2 instance with an Elastic IP address. Deploying SAProuter on an EC2 instance with an Elastic IP address preserves the existing SAProuter configuration and ensures a stable endpoint that can be referenced in firewall rules and SAP routing tables. Option B (AWS NAT Gateway) is incorrect because a NAT Gateway is used for outbound internet traffic from private subnets and does not provide a persistent inbound endpoint for SAProuter connections. Option C (AWS Site-to-Site VPN) is incorrect because while a VPN provides secure connectivity between on-premises and AWS, it does not replace the need for SAProuter, which operates at the application layer. Option D (Application Load Balancer) is incorrect because an ALB is designed for HTTP/HTTPS traffic and cannot handle the proprietary protocol used by SAProuter.

Answer

Use an AWS NAT Gateway to route traffic

Answer

Establish an AWS Site-to-Site VPN connection

Answer

Use an AWS Application Load Balancer

Question 5

During an SAP migration, the migration team needs to ensure that all SAP system IDs (SIDs) are unique across the AWS environment. Which AWS service can be used to centrally manage and enforce this uniqueness?

Accepted Answer

AWS Service Catalog. AWS Service Catalog can define product portfolios with constraints, including preventing duplicate SIDs. Option B is wrong because AWS Config audits resources but doesn't enforce uniqueness. Option C is wrong because AWS Resource Access Manager shares resources, not manages SIDs. Option D is wrong because AWS CloudTrail logs API calls.

Answer

AWS Config

Answer

AWS Resource Access Manager

Answer

AWS CloudTrail

Question 6

A company is migrating an SAP Business Suite system to AWS. The current on-premises system uses Oracle Database with Automatic Storage Management (ASM). The target database on AWS will be SAP HANA. Which migration strategy minimizes data conversion efforts?

Accepted Answer

Use the SAP HANA Database Migration Option (DMO) with SUM. The SAP HANA Database Migration Option (DMO) with SUM is the correct choice because it is specifically designed for migrating to SAP HANA, handling both data and schema conversion automatically, minimizing manual effort. Option A is incorrect because although AWS DMS supports SAP HANA as a target, it is not the optimal tool for SAP system migration due to the lack of integrated SAP-specific schema and data conversion capabilities. Option B is incorrect because SAP Landscape Transformation (SLT) is primarily for real-time data replication and does not provide the same level of integrated conversion. Option D is incorrect because export/import requires significant manual data conversion and transformation, increasing effort and risk.

Answer

Use AWS Database Migration Service (DMS) with Oracle as source and HANA as target

Answer

Use SAP Landscape Transformation (SLT) for real-time data replication

Answer

Perform an export/import of the Oracle database and import into HANA

Question 7

A company plans to migrate its SAP systems to AWS and needs to set up a secure connection to the corporate data center. The company requires consistent network performance and low latency. Which AWS service should be used?

Accepted Answer

AWS Direct Connect. (AWS Direct Connect) is correct because it provides a dedicated private network connection from the corporate data center to AWS, ensuring consistent network performance and low latency. Option A (AWS Transit Gateway) is a network transit hub but does not itself provide a direct connection; it can be used with Direct Connect or VPN attachments. Option B (AWS Site-to-Site VPN) uses the public internet, which can lead to variable performance and latency. Option D (AWS Client VPN) is designed for individual remote clients, not for site-to-site connectivity.

Answer

AWS Transit Gateway

Answer

AWS Site-to-Site VPN

Answer

AWS Client VPN

Question 8

An SAP system on AWS is experiencing performance issues. The system uses a shared file system (SAP transport directory) mounted from an NFS server. During migration, the team wants to improve performance and reduce complexity. Which AWS service should replace the NFS server?

Accepted Answer

Amazon EFS. Amazon EFS provides a fully managed NFS file system that can be shared across multiple EC2 instances, making it an ideal replacement for the NFS server in SAP transport directory scenarios. Option A (Amazon S3 with S3FS) is incorrect because S3 is object storage and S3FS is a FUSE-based tool that adds complexity and can cause performance issues, not suitable for SAP transport. Option B (Amazon FSx for Windows File Server) is incorrect because it uses SMB protocol, while SAP transport directories typically require NFS and run on Linux instances. Option C (AWS Storage Gateway file gateway) adds unnecessary complexity as it is designed for hybrid storage and caching, not as a direct NFS replacement for this use case.

Answer

Amazon S3 with S3FS

Answer

Amazon FSx for Windows File Server

Answer

AWS Storage Gateway (file gateway)

Question 9

A company is migrating an SAP system to AWS and needs to ensure high availability for SAP Central Services (ASCS) and Enqueue Replication Server (ERS). Which architecture meets SAP's high availability requirements?

Accepted Answer

Use a cluster solution with a shared file system and a virtual IP address in a multi-AZ setup. A cluster solution with a shared file system and a virtual IP address in a multi-AZ setup meets SAP's high availability requirements for ASCS and ERS. This architecture ensures automatic failover across Availability Zones (AZs) and is the standard recommendation for SAP HA. Option B is incorrect because deploying ASCS and ERS in a single AZ with automatic restart does not protect against AZ failure. Option C is incorrect because an Application Load Balancer is designed for HTTP/HTTPS traffic, not for SAP Central Services which require a shared file system and virtual IP. Option D is incorrect because Amazon Route 53 health checks alone do not provide the fast failover required; they are typically used with DNS-based failover, not cluster-based HA.

Answer

Deploy ASCS and ERS in a single Availability Zone with an automatic restart

Answer

Use an Application Load Balancer to distribute traffic between ASCS and ERS

Answer

Configure Amazon Route 53 health checks to failover between ASCS and ERS

Question 10

During an SAP migration, the team needs to transfer a large number of small files (SAP transport requests) from on-premises to AWS. Which AWS service is most cost-effective for this transfer?

Accepted Answer

AWS DataSync. AWS DataSync is optimized for efficiently transferring millions of small files, such as SAP transport requests, over the network, and is cost-effective for most data volumes without network constraints. It uses parallel threading and metadata handling to accelerate small-file transfers. In contrast, option D (AWS Snowcone) incurs shipping costs and device rental fees, making it less cost-effective for this type of transfer.

Answer

AWS Transfer Family (SFTP)

Answer

AWS Snowmobile

Answer

AWS Snowcone

Question 11

Which TWO AWS services can be used to monitor the performance of an SAP HANA database on AWS? (Select TWO.)

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch (option B) can monitor SAP HANA metrics such as CPU, memory, and disk I/O via custom metrics or the SAP HANA plugin. Amazon RDS Performance Insights (option D) provides database-specific performance metrics and SQL-level analysis when SAP HANA is deployed on Amazon RDS. Option A is incorrect because AWS Trusted Advisor offers best-practice checks, not real-time performance monitoring. Option C is wrong because AWS X-Ray traces application requests, not database performance. Option E is wrong because AWS Config audits configuration changes, not performance.

Answer

AWS Trusted Advisor

Answer

AWS X-Ray

Answer

AWS Config

Question 12

Which THREE factors should be considered when choosing an instance type for an SAP HANA database on AWS? (Select THREE.)

Accepted Answer

Memory size of the instance. Options A, B, and E are correct. Memory size (A) is critical because SAP HANA is an in-memory database. The instance must be certified for SAP HANA (B) to ensure compatibility and support. Network throughput (E) is important for data replication and client access. Option C is incorrect because the number of attachable EBS volumes is not a primary selection criterion for SAP HANA. Option D is incorrect because GPU capabilities are not required for SAP HANA.

Answer

Number of EBS volumes that can be attached

Answer

GPU capabilities of the instance

Question 13

Which TWO of the following are valid methods for migrating SAP systems to AWS? (Select TWO.)

Accepted Answer

System Copy (SAP). The correct answers are A and B. System Copy (SAP) is a standard SAP migration method that replicates an entire SAP system. SAP DMO with SUM is a dedicated migration tool for migrating to SAP HANA, including upgrades. Option C (AWS SMS) is a general server migration service that does not handle SAP-specific components. Option D (AWS DMS) is primarily a database migration tool and does not migrate the SAP application layer or its configurations, making it unsuitable for a complete SAP system migration. Option E (VM Import/Export) can move VM images but lacks SAP-specific migration capabilities and post-migration automation required for SAP systems.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (DMS)

Answer

VM Import/Export

Question 14

A company is migrating its SAP ERP system running on Oracle Database to SAP HANA on AWS. The current on-premises environment has a 5 TB Oracle database with high transaction volume. The migration must be completed within a 4-hour downtime window. The target environment on AWS uses an SAP-certified instance with 1 TB of RAM. The company has a 1 Gbps AWS Direct Connect connection. The migration team is considering using SAP DMO with SUM. However, during a test run, the database export took 6 hours, exceeding the downtime window. What should the migration team do to meet the 4-hour downtime window?

Accepted Answer

Use the SAP HANA Database Migration Option (DMO) with the 'load and move' method. Using the SAP HANA Database Migration Option (DMO) with the 'load and move' method allows the initial data load to be performed during the preparation phase before the downtime window, and only a delta transfer (incremental data) during the actual downtime. This significantly reduces the downtime required compared to the standard DMO method that does the full export and import during downtime. Option A is wrong because performing a system copy to Oracle on AWS first does not directly migrate to SAP HANA and adds unnecessary steps and time. Option C is wrong because upgrading to a larger EC2 instance may improve processing speed but does not address the bottleneck of the 1 Gbps network bandwidth; the export time is limited by network speed. Option D is wrong because AWS Snowball Edge introduces additional time for shipping and data transfer, which would likely exceed the 4-hour window, and it is not optimized for the delta sync required for such a short downtime.

Answer

Perform a system copy to an Oracle database on AWS first, then migrate to HANA

Answer

Upgrade to a larger EC2 instance type with more CPU and memory for the HANA database

Answer

Use AWS Snowball Edge to transfer the initial data and then perform a delta sync

Question 15

A company is migrating an on-premises SAP HANA database to AWS. The database is 2 TB in size, and the network link has a bandwidth of 1 Gbps with an average utilization of 40% during the migration window. They need to minimize the migration time. Which approach should they use?

Accepted Answer

Use AWS Snowball Edge to transfer the data physically.. AWS Snowball Edge is the most efficient approach for large data transfers (2 TB) over a constrained network (1 Gbps at 40% utilization ≈ 400 Mbps). It physically ships the data, avoiding network bottlenecks entirely. Option A is correct. Option B is wrong because requesting a bandwidth increase is impractical and may not be feasible. Option C is wrong: AWS DMS with ongoing replication minimizes downtime for incremental changes, but the initial full load would still be slow over the constrained network, increasing total migration time. Option D is wrong: Amazon S3 Transfer Acceleration only speeds up uploads to S3, not to SAP HANA directly, and it still relies on the network link.

Answer

Request a temporary bandwidth increase from the ISP.

Answer

Use AWS Database Migration Service (DMS) with ongoing replication to minimize downtime.

Answer

Use Amazon S3 Transfer Acceleration to speed up the transfer.
