PAS-C01 Migration Practice Test 12 — 15 Questions

Question 1

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. Option D is correct because AWS Snowball can handle large data volumes and reduce network transfer time. Option A is wrong because AWS DMS is better for ongoing replication, not initial bulk load. Option B is wrong because AWS Direct Connect is a network connection, not a data transfer service. Option C is wrong because AWS S3 Transfer Acceleration speeds up uploads but still uses the internet.

Answer

AWS Database Migration Service (DMS) with ongoing replication

Answer

AWS Direct Connect

Answer

Amazon S3 Transfer Acceleration

Question 2

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. Option C is correct because placing application servers in the same placement group and Availability Zone as the database reduces network distance and latency. Option A is wrong because using a larger instance type may not reduce latency. Option B is wrong because enabling Enhanced Networking reduces packet loss but not latency across AZs. Option D is wrong because VPC Peering does not improve latency within the same region.

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 3

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. Option C is correct because deploying SAProuter on an EC2 instance with an Elastic IP ensures a stable endpoint and maintains existing SAProuter rules. Option A is wrong because a NAT Gateway does not support SAProuter directly. Option B is wrong because a VPN connection does not replace SAProuter. Option D is wrong because an Application Load Balancer is for HTTP/HTTPS traffic, not 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 4

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. Option A is correct because 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 CloudTrail logs API calls. Option D is wrong because AWS Resource Access Manager shares resources, not manages SIDs.

Answer

AWS Config

Answer

AWS Resource Access Manager

Answer

AWS CloudTrail

Question 5

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. Option D is correct because SAP Landscape Transformation (SLT) can replicate data from Oracle to HANA in real-time, handling the conversion. Option A is wrong because AWS DMS does not support SAP HANA as a target. Option B is wrong because the SAP HANA Database Migration Option (DMO) is for migrating from any SAP-supported source to HANA, but it requires a specific SAP system. Option C is wrong because homogenous migration is not possible when changing database types.

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 6

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. Option D is correct because AWS Direct Connect provides a dedicated network connection with consistent performance. Option A is wrong because a VPN over the internet may have variable performance. Option B is wrong because AWS Client VPN is for individual clients. Option C is wrong because AWS Transit Gateway is a network hub, not a connection.

Answer

AWS Transit Gateway

Answer

AWS Site-to-Site VPN

Answer

AWS Client VPN

Question 7

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. Option B is correct because Amazon EFS provides a scalable NFS file system that can be shared across multiple EC2 instances. Option A is wrong because Amazon S3 is not a file system. Option C is wrong because AWS Storage Gateway provides file shares but adds complexity. Option D is wrong because Amazon FSx for Windows File Server is for Windows workloads, not SAP typically.

Answer

Amazon S3 with S3FS

Answer

Amazon FSx for Windows File Server

Answer

AWS Storage Gateway (file gateway)

Question 8

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. Option D is correct because using a cluster with a shared file system and a virtual IP address in a multi-AZ deployment is the standard SAP HA architecture. Option A is wrong because a single AZ does not protect against AZ failure. Option B is wrong because an Application Load Balancer is not suitable for ASCS/ERS. Option C is wrong because Route 53 health checks alone do not provide the fast failover required.

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 9

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 Snowcone. Option B is correct because AWS Snowcone is a small, rugged device suitable for transferring small amounts of data or small files. Option A is wrong because AWS Snowmobile is for exabytes of data. Option C is wrong because AWS DataSync is for large datasets over network. Option D is wrong because AWS Transfer Family is for file transfer workflows, not bulk data movement.

Answer

AWS Transfer Family (SFTP)

Answer

AWS Snowmobile

Answer

AWS DataSync

Question 10

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

Accepted Answer

Amazon CloudWatch. Options A and D are correct. Amazon CloudWatch can monitor metrics like CPU and memory. Amazon RDS Performance Insights provides database-specific metrics. Option B is wrong because AWS Trusted Advisor provides best-practice checks, not performance monitoring. Option C is wrong because AWS X-Ray is for tracing distributed applications. Option E is wrong because AWS Config is for configuration auditing.

Answer

AWS Trusted Advisor

Answer

AWS X-Ray

Answer

AWS Config

Question 11

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 D are correct. SAP HANA requires certified instance types (A), memory must be sufficient for the data (B), and network performance is critical for throughput (D). Option C is wrong because GPU is not required for HANA. Option E is wrong because EBS-optimized instances are already required for HANA, but the instance type itself determines that; it's not a separate consideration.

Answer

Number of EBS volumes that can be attached

Answer

GPU capabilities of the instance

Question 12

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

Accepted Answer

System Copy (SAP). Options A and D are correct. System Copy is a standard SAP migration method. SAP DMO with SUM is a tool for migrating to SAP HANA. Option B is wrong because AWS DMS does not support SAP HANA as a target. Option C is wrong because VM Import/Export is for VMware, not directly for SAP migration. Option E is wrong because AWS Server Migration Service (SMS) is for server-level migration, not SAP-specific.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (DMS)

Answer

VM Import/Export

Question 13

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. Option C is correct because using the SAP HANA Database Migration Option (DMO) with the 'load and move' approach allows initial data load during the migration preparation phase and then only a delta transfer during the downtime window, reducing downtime. Option A is wrong because a larger instance may speed up processing but the export time is limited by the network (1 Gbps). Option B is wrong because AWS Snowball would add time for shipping and data transfer, likely exceeding the window. Option D is wrong because a homogenous migration to another Oracle database does not address the requirement to migrate to HANA.

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 14

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 for large data transfers over limited bandwidth; it avoids network bottlenecks. Option A is wrong because AWS DMS with ongoing replication is better for minimal downtime but initial load is slow over constrained network. Option B is wrong because increasing bandwidth is not feasible. Option D is wrong because S3 Transfer Acceleration only speeds up uploads to S3, not to SAP HANA directly.

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.

Question 15

During the migration of an SAP ERP system to AWS, the SAP application team reports that after migrating the database to Amazon RDS for SAP HANA, batch jobs that previously ran in 2 hours now take 5 hours. The system uses AWS Direct Connect with adequate bandwidth. Which action is most likely to resolve this performance issue?

Accepted Answer

Increase the RDS instance size and storage IOPS.. SAP HANA on RDS uses a single-AZ deployment by default; enabling Multi-AZ adds a standby but does not improve performance. However, the most impactful change is increasing the instance size (compute and memory) to match the on-premises capacity. Option A is wrong because RDS Multi-AZ does not improve performance. Option B is wrong because the bandwidth is already adequate. Option D is wrong because reducing backup retention does not affect runtime performance.

Answer

Enable Multi-AZ deployment for RDS.

Answer

Reduce the automated backup retention period.

Answer

Increase the Direct Connect bandwidth.
