PAS-C01 Migration Practice Test 21 — 15 Questions

Question 1

Refer to the exhibit. A CloudFormation template is used to migrate a web server to AWS. The template launches an EC2 instance but does not install the web server. What is the best way to automate the installation?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Add a UserData property to the EC2 instance resource.. The EC2 UserData property in a CloudFormation template lets you pass a script that runs automatically on first boot, so the web server installation happens as part of instance launch. This keeps the automation inside the template and requires no external orchestration.

Answer

Create a CloudWatch Events rule to trigger a Lambda function after instance launch.

Answer

Use AWS Systems Manager Run Command to install the web server.

Answer

Use AWS CodeDeploy to deploy the web server after the instance is created.

Question 2

A company wants to migrate its SAP HANA database to AWS using SAP HANA Database Backup and Recovery. The backup files are stored on an NFS share on-premises. The company wants to restore these backups directly to an Amazon EC2 instance running SAP HANA. Which AWS storage service should they use to make the NFS backup files accessible to the EC2 instance?

Accepted Answer

Amazon EFS. Amazon EFS provides a scalable NFS file system that can be mounted on EC2 instances. The backup files can be copied from on-premises NFS to EFS using AWS DataSync or other methods, and then used for restore. Options A, B, D are incorrect because S3 is object storage (not NFS), FSx for Windows File Server is SMB, and EBS is block storage not NFS.

Answer

Amazon S3

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS

Question 3

A company wants to migrate its SAP BusinessObjects system to AWS. The system includes a CMS database that runs on Microsoft SQL Server. The company wants to use AWS DMS to migrate the database with minimal downtime. Which migration method should they use?

Accepted Answer

Full load with ongoing replication (change data capture). Full load with ongoing replication (change data capture) performs an initial bulk load and then continuously replicates ongoing changes from the source SQL Server to the target, keeping downtime to a minimum during cutover. This is the standard AWS DMS approach for minimal-downtime migrations of active databases. A one-time full load would require a maintenance window and cause extended downtime.

Answer

Snapshot restore to Amazon RDS

Answer

Full load with one-time restore

Answer

Full load only

Question 4

A company is migrating its SAP ERP system to AWS. The system has a custom ABAP code that uses RFC calls to an external system. The company wants to test the migrated system in a sandbox environment before the final cutover. What is the best practice for handling the RFC connections during testing?

Accepted Answer

Create a separate sandbox environment that is isolated from production and uses mock endpoints for RFC calls.. The best practice for testing custom ABAP RFC calls in a sandbox is to isolate the environment and replace real external endpoints with mock endpoints. This prevents the sandbox from inadvertently affecting production systems or external partners, while still allowing the RFC call logic to be exercised. Mock endpoints simulate the external system's responses, so the ABAP code can be tested for correctness without requiring the actual external system to be available or risking unintended side effects.

Answer

Use the same RFC destinations as production but disable the external system.

Answer

Set up a VPN between the sandbox and the external system to test real connectivity.

Answer

Configure the sandbox to use the production RFC endpoints but with read-only access.

Question 5

A company is migrating a critical Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service should they use to perform an online migration with minimal impact?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports ongoing replication and can perform live migrations with minimal downtime. AWS Snowball is for offline data transfer. S3 Transfer Acceleration speeds up uploads to S3. Direct Connect establishes dedicated network connections but is not a migration service.

Answer

AWS Direct Connect

Answer

AWS Snowball

Answer

Amazon S3 Transfer Acceleration

Question 6

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). Rehost (lift-and-shift) involves moving the application to AWS without making changes to the code or architecture. Since the company wants to use the same SAP version without re-implementation, rehosting is the correct strategy. It minimizes modifications and is the fastest migration path for legacy SAP ERP systems.

Answer

Refactor / Re-architect

Answer

Retire

Answer

Replatform (Lift, tinker, and shift)

Question 7

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.. For SAP workloads on AWS, SAP's and AWS's joint best-practice guidance is to keep the application and database in the same VPC and, where possible, the same Availability Zone to minimize network latency and maximize bandwidth between the app tier and the DB tier. Cross-AZ traffic adds roughly 1–2 ms of latency and is billed, which can degrade SAP performance and increase cost.

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 8

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). The Application Load Balancer (ALB) operates at Layer 7 and is the correct choice for distributing HTTP/HTTPS traffic across multiple SAP BusinessObjects Web Application Server instances. ALB supports path-based and host-based routing, health checks at the HTTP level, and sticky sessions, all of which are needed for web application tiers. This makes it the standard AWS service for high availability of web application servers.

Answer

AWS Global Accelerator

Answer

Network Load Balancer (NLB)

Answer

Amazon Route 53

Question 9

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.. SAP Landscape Virtualization Management (LVM) orchestrates system copy and refresh by connecting from the LVM server to the target host over network ports (typically SSH on 22 or SAP-specific ports). If the target host is unreachable, the most likely cause is that the security group attached to the target EC2 instance does not permit inbound traffic from the LVM instance's security group or IP. This is a classic network-layer misconfiguration in AWS migrations.

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 10

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 11

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 is the native Infrastructure as Code (IaC) service on AWS, allowing you to model and provision AWS resources using declarative templates in JSON or YAML. It supports a wide range of AWS services, including those needed for SAP environments (e.g., EC2, VPC, EBS, RDS), and enables repeatable, version-controlled deployments. CloudFormation also handles dependencies, rollback on failure, and drift detection, making it ideal for automating complex SAP infrastructure provisioning.

AWS Fargate

Question 14

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 performs a full load followed by change data capture (CDC) from the source Oracle database to the RDS target, keeping the target in sync with minimal downtime. The cutover can be scheduled during the maintenance window with only a brief application pause, ensuring data consistency and minimizing downtime for a 2 TB database.

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 15

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 is a fully managed, scalable, elastic NFS file system for Linux-based workloads on AWS. It supports the NFSv4.1 protocol, making it a direct replacement for on-premises NFS shares used by SAP transport directories. EFS integrates natively with SAP-certified instances and provides shared, concurrent access across multiple EC2 instances and Availability Zones, which is essential for SAP transport directories.
