PAS-C01 Migration Practice Test 8 — 15 Questions

Question 1

A company is migrating a legacy SAP ERP system with a large ABAP codebase to AWS. They want to use the same SAP version without re-implementation. Which migration strategy should they adopt?

Accepted Answer

Rehost (Lift-and-shift). Lift-and-shift (rehost) moves the existing system as-is to AWS, preserving the ABAP codebase and SAP version. Replatform may involve minor changes. Refactor/Re-architect would require re-implementation. Retire is not applicable.

Answer

Refactor / Re-architect

Answer

Retire

Answer

Replatform (Lift, tinker, and shift)

Question 2

A company is migrating an SAP system to AWS and needs to ensure that the SAP application can communicate with the database over a low-latency, high-bandwidth connection. What is the best practice for network architecture?

Accepted Answer

Place the SAP application and database in the same VPC and same Availability Zone.. Placing the SAP application and database in the same VPC and Availability Zone minimizes latency. Separate AZs increase latency. Different regions introduce significant latency. On-premises connection defeats purpose of migration.

Answer

Place the SAP application on-premises and the database on AWS.

Answer

Place the SAP application and database in separate Availability Zones within the same region.

Answer

Place the SAP application in a different AWS Region than the database.

Question 3

A company is planning to migrate an SAP BusinessObjects environment to AWS. They need to ensure high availability for the Web Application Server tier. Which AWS service should they use to distribute traffic across multiple instances?

Accepted Answer

Application Load Balancer (ALB). An Application Load Balancer (ALB) distributes HTTP/HTTPS traffic across targets. NLB is for TCP/UDP. Global Accelerator improves performance but not primarily for load balancing. Route 53 is DNS.

Answer

AWS Global Accelerator

Answer

Network Load Balancer (NLB)

Answer

Amazon Route 53

Question 4

An organization is migrating a large SAP ERP system using SAP Landscape Virtualization Management (LVM) for system copy and refresh. During the migration, they encounter an error in LVM indicating that the target host is not reachable. What is the most likely cause?

Accepted Answer

The security groups do not allow inbound traffic from the LVM instance to the target host.. Security groups controlling traffic between source and target are a common cause. IAM roles affect AWS API calls, not network connectivity. S3 permissions are irrelevant. AWS DMS is not used.

Answer

The S3 bucket used for backup is not accessible.

Answer

The IAM role assigned to the LVM instance does not have sufficient permissions.

Answer

The AWS Database Migration Service is not configured correctly.

Question 5

A company is migrating an SAP system and wants to use a storage solution that provides persistent, high-performance block storage for the SAP HANA database. Which AWS storage option should they choose?

Accepted Answer

Amazon EBS io2 Block Express. Amazon EBS io2 Block Express volumes provide high performance and durability for HANA. EFS is file storage. S3 is object storage. Instance store is ephemeral.

Answer

Amazon EC2 Instance Store

Answer

Amazon Elastic File System (EFS)

Answer

Amazon S3

Question 6

A company is migrating an SAP environment and wants to automate the provisioning of infrastructure using Infrastructure as Code (IaC). Which AWS service should they use to define and deploy AWS resources?

Accepted Answer

AWS CloudFormation. AWS CloudFormation allows you to define infrastructure as code. OpsWorks is for configuration management. Elastic Beanstalk is for application deployment. CodeDeploy is for code deployment.

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Answer

AWS Elastic Beanstalk

Question 7

A company is migrating an SAP system to AWS and wants to ensure that the migration process is compliant with SAP's requirements. Which TWO of the following are recommended practices? (Choose 2)

Accepted Answer

Follow SAP migration notes and best practices.. Using certified EC2 instance types and following SAP notes are mandatory. Reducing memory is not recommended. Using unsupported DB engines violates compliance. Skipping testing is risky.

Answer

Use a database engine that is not supported by SAP to reduce licensing costs.

Answer

Skip the testing phase to accelerate the migration timeline.

Answer

Reduce the memory allocation of the SAP application to save costs.

Question 8

A company is migrating an SAP HANA database to AWS. Which TWO of the following are valid options for running SAP HANA on AWS? (Choose 2)

Accepted Answer

Amazon EC2 instances with Amazon EBS storage. SAP HANA can run on EC2 instances with EBS or on AWS HANA Large Instances. RDS for SAP HANA is not available. Lightsail is not suitable for HANA. Fargate is for containers.

Answer

Amazon RDS for SAP HANA

Answer

AWS Lambda

Answer

AWS Fargate

Question 9

An SAP administrator runs the AWS CLI command shown in the exhibit. The SAP application is experiencing performance issues. The administrator notices that one instance is stopped. What is the most likely impact of this on the SAP landscape?

Accepted Answer

The SAP application will be unavailable or have reduced capacity.. If the SAP application server is stopped, the application will be unavailable or degraded. The database is not shown. Stopped instances do not incur compute charges. Instance type mismatch is not the issue; the running instance is larger.

Answer

The SAP system will be fully functional as long as the database is running.

Answer

The running instance will automatically take over the workload.

Answer

The stopped instance will continue to incur charges.

Question 10

An administrator uses AWS Launch Wizard to deploy an SAP S/4HANA system with high availability. After deployment, they notice that only one database instance is created. What is the most likely reason?

Accepted Answer

The deployment encountered an error and only created one instance.. High availability for SAP HANA typically requires at least two nodes (primary and secondary). If only one is created, the HA configuration may have failed or the parameter was ignored. The backup retention and instance classes are correct.

Answer

The instance class r5.8xlarge is not certified for HANA.

Answer

The HighAvailability parameter was set to false.

Answer

The Launch Wizard does not support HA for HANA.

Question 11

A company is migrating a legacy on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB and has a 1-hour maintenance window. The company needs to minimize downtime and ensure data consistency. Which migration strategy should be used?

Accepted Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication from the source to the target.. AWS DMS with ongoing replication minimizes downtime by continuously replicating changes from the source to the target, allowing a cutover with minimal downtime. Native Oracle tools (Data Pump) or exporting to flat files require significant downtime, and AWS SCT only handles schema conversion.

Answer

Use Oracle Data Pump to export and import the database during the maintenance window.

Answer

Use AWS Schema Conversion Tool (AWS SCT) to convert the schema and then copy data manually.

Answer

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

Question 12

A company is migrating a critical SAP HANA database from on-premises to AWS. The database is 6 TB, and the migration must be completed within a 4-hour downtime window. The network bandwidth between on-premises and AWS is 1 Gbps. Which approach should the company take to meet the downtime requirement?

Accepted Answer

Use AWS Snowball Edge to physically transfer the data, then use AWS DMS for ongoing replication.. AWS Snowball Edge enables physical transfer of the 6 TB data, which is feasible within the 4-hour window despite the 1 Gbps network constraint. After the initial load, AWS DMS can be used for ongoing CDC replication. Option A is wrong because converting schema with SCT and restoring after upload still requires the initial upload over the network, which would exceed the downtime window. Option B is wrong because AWS DMS with CDC over the existing network for the full load cannot transfer 6 TB in 4 hours at 1 Gbps. Option D is wrong because a direct online migration over the network cannot meet the downtime requirement due to bandwidth limitations.

Answer

Use AWS SCT to convert the schema, then export to Amazon S3 and restore into HANA on EC2.

Answer

Use AWS DMS with change data capture (CDC) and start with a full load over the network.

Answer

Perform a direct online migration using AWS DMS over the existing network.

Question 13

A company is migrating its SAP application from on-premises to AWS. The SAP application uses a shared file system (NFS) for transport directories. Which AWS service should the company use to replace the on-premises NFS?

Accepted Answer

Amazon EFS. Amazon EFS provides a scalable NFS file system that can be shared across multiple EC2 instances, making it suitable for SAP transport directories. Option A is wrong because Amazon FSx for Windows File Server uses SMB protocol, not NFS. Option B is wrong because Amazon S3 is object storage, not a file system. Option C is wrong because Amazon EBS is block storage attached to a single instance and cannot be shared across multiple instances natively.

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3

Answer

Amazon EBS

Question 14

A company is migrating its SAP NetWeaver system from on-premises to AWS. The system uses a central instance (ASCS) and multiple dialog instances. The migration must be completed with minimal downtime. Which approach should the company use?

Accepted Answer

Use SAP Software Provisioning Manager (SWPM) to perform a system copy into pre-provisioned EC2 instances with the same sizing.. Using SAP Software Provisioning Manager (SWPM) to perform a system copy into pre-provisioned EC2 instances with the same sizing allows for a controlled, minimal-downtime migration. SWPM handles SAP-specific consistency, enabling a homogeneous system copy that can be completed with minimal downtime by pre-loading data and then applying incremental changes. Option B is wrong because AWS CloudEndure Migration (replaced by AWS Application Migration Service) replicates at the block level, which may not maintain SAP application consistency without additional steps. Option C is wrong because uninstalling and performing a fresh installation requires significant downtime and reconfiguration. Option D is wrong because AWS Application Migration Service replicates at the block level and may not handle SAP application consistency optimally, potentially requiring additional validation and downtime.

Answer

Use AWS CloudEndure Migration to continuously replicate the SAP system.

Answer

Uninstall SAP from on-premises and perform a fresh installation on AWS, then restore the database backup.

Answer

Use AWS Application Migration Service (AWS MGN) to replicate the entire on-premises system to AWS.

Question 15

A company is migrating its SAP ERP system to AWS. The SAP application requires low-latency access to the database and high network throughput between application and database tiers. Which AWS architecture should the company use?

Accepted Answer

Use a placement group with enhanced networking for both application and database instances.. Using a placement group with enhanced networking for both application and database instances ensures low latency and high network throughput between tiers. Option A is incorrect because placing the SAP application servers in a different AWS Region than the database adds significant latency due to geographic distance. Option B is incorrect because Amazon S3 is an object storage service, not a suitable database storage layer for SAP ERP, which requires block storage with low latency. Option C is incorrect because placing the application servers in one Availability Zone and the database in another Availability Zone introduces additional network latency compared to placing them in the same AZ with a placement group.

Answer

Place the SAP application servers in a different AWS Region than the database.

Answer

Use Amazon S3 as the database storage layer.

Answer

Place the SAP application servers in one Availability Zone and the database in another Availability Zone.
