PAS-C01 Migration Practice Test 20 — 15 Questions

Question 1

A company is migrating an SAP system to AWS and wants to use AWS Systems Manager for patching. The SAP application server is running Windows. What is a prerequisite for Systems Manager to manage the instance?

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

Accepted Answer

Install the AWS Systems Manager Agent (SSM Agent) on the instance. AWS Systems Manager requires the SSM Agent to be installed and running on managed instances to perform patching and other management operations. The SSM Agent processes Systems Manager requests, executes run commands, and reports instance state back to the Systems Manager service. Without the agent, the instance cannot communicate with the Systems Manager endpoint or receive patching instructions.

Answer

Install the Amazon CloudWatch agent on the instance

Answer

Enable AWS Config on the instance

Answer

Assign a public IP address to the instance

Question 2

An organization is migrating an SAP system from on-premises to AWS. The SAP system uses a shared file system (NFS) for transport directories. The company wants a fully managed NFS solution on AWS. Which service should they use?

Accepted Answer

Amazon Elastic File System (EFS). Amazon EFS is a fully managed NFS file system that supports the NFSv4.1 and NFSv4.0 protocols, making it the ideal choice for SAP transport directories that require a shared POSIX-compliant file system. It provides high availability, automatic scaling, and eliminates the need to manage underlying storage infrastructure, directly matching the requirement for a fully managed NFS solution on AWS.

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3

Question 3

A company is migrating an SAP system to AWS and wants to use AWS Backup to back up the SAP HANA database. What is a prerequisite for using AWS Backup with SAP HANA?

Accepted Answer

Install the AWS Backup agent for SAP HANA on the database instance. AWS Backup for SAP HANA requires the AWS Backup agent to be installed on the SAP HANA database instance. This agent is a software component that integrates with SAP HANA's native backup capabilities, enabling AWS Backup to orchestrate and manage full, incremental, and differential backups of the HANA database. Without the agent, AWS Backup cannot communicate with the SAP HANA system to initiate or manage backups.

Answer

Configure AWS Storage Gateway to store backups

Answer

Use AWS CloudEndure for backup

Answer

Set up AWS Database Migration Service (DMS) for continuous backup

Question 4

A company is migrating an SAP system to AWS. They want to use AWS Launch Wizard to deploy SAP. Which TWO prerequisites are required for using Launch Wizard? (Choose TWO.)

Accepted Answer

An EC2 key pair for SSH access to the SAP instances. Option A is correct because AWS Launch Wizard requires an existing EC2 key pair so it can associate it with the launched SAP instances and allow SSH access for administration and troubleshooting. Option C is correct because Launch Wizard needs an IAM role (or user credentials) with the appropriate permissions to create and manage the underlying AWS resources such as EC2 instances, EBS volumes, security groups, and CloudFormation stacks on your behalf. Option B is not required because Direct Connect is only a connectivity choice for hybrid scenarios, not a Launch Wizard prerequisite. Option D is not required because Launch Wizard does not mandate an AWS Organization with all features enabled. Option E is not required because SAP software can be brought via your own media/license or Marketplace, but a Marketplace subscription is not a mandatory prerequisite for using Launch Wizard.

Answer

AWS Direct Connect connection to on-premises

Answer

An AWS Organization with all features enabled

Answer

A subscription to SAP software in AWS Marketplace

Question 5

A company is migrating an SAP system to AWS and wants to use AWS Systems Manager for patching. The SAP application server is running Windows. What is a prerequisite for Systems Manager to manage the instance?

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

Accepted Answer

AWS CloudFormation. AWS CloudFormation (D) is correct because it lets you model the entire SAP landscape as code using templates (JSON/YAML) and deploy it in a repeatable, automated way, and AWS provides SAP-specific CloudFormation templates that follow AWS best practices for SAP HANA and SAP NetWeaver. AWS Launch Wizard (E) is correct because it is purpose-built to guide and automate the deployment of SAP applications on AWS, sizing the environment, provisioning the underlying resources, and applying AWS best practices for SAP HANA and SAP NetWeaver. AWS OpsWorks (A) is a configuration-management service (Chef/Puppet) and is not the SAP deployment automation service intended here. AWS Elastic Beanstalk (B) targets web application deployment and does not support SAP workloads. AWS CodeDeploy (C) automates application code deployments to EC2/on-premises instances but does not provision or size SAP infrastructure according to SAP best practices.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Question 6

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a high transaction rate. The migration must have minimal downtime. Which AWS service should be used for the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is designed to migrate databases to AWS with minimal downtime by continuously replicating data changes while the source remains operational. It supports homogeneous migrations like Oracle to RDS for Oracle and can handle high transaction rates with change data capture (CDC). DMS is the correct choice for a 2 TB database requiring minimal downtime.

Answer

AWS Snowball Edge

Answer

AWS Server Migration Service (SMS)

Answer

AWS DataSync

Question 7

An organization is migrating a legacy application to AWS. The application requires a static IP address for client whitelisting. After migrating the application to an Application Load Balancer (ALB) with an Auto Scaling group, clients report connection failures. What should be done to resolve this issue?

Accepted Answer

Replace the ALB with a Network Load Balancer (NLB) and assign an Elastic IP.. An Application Load Balancer (ALB) does not support static IP addresses; its IP addresses can change. To provide a static IP for client whitelisting, you should replace the ALB with a Network Load Balancer (NLB), which supports Elastic IP addresses. This allows clients to whitelist a fixed IP. Placing an Nginx reverse proxy in front of the ALB with an Elastic IP is a workaround but adds complexity and is not the best practice. Assigning an Elastic IP directly to an ALB is not possible. Round-robin routing does not address the static IP requirement.

Answer

Place an Nginx reverse proxy in front of the ALB with an Elastic IP.

Answer

Assign an Elastic IP to the ALB.

Answer

Configure the ALB to use a round-robin routing algorithm.

Question 8

A company is migrating a SAP HANA database to AWS. Which storage configuration is recommended for SAP HANA to meet performance requirements?

Accepted Answer

Amazon EBS io2 Block Express volumes. Amazon EBS io2 Block Express volumes are the recommended storage configuration for SAP HANA on AWS because they provide up to 4,000 MB/s throughput per volume and 256,000 IOPS, with 99.999% durability. This meets the high-performance, low-latency requirements of SAP HANA, which demands consistent sub-millisecond latency for its columnar in-memory database operations. io2 Block Express volumes also support multi-attach for SAP HANA scale-out configurations and are the only EBS volume type validated by SAP for production HANA workloads.

Answer

Amazon EC2 instance store volumes

Answer

Amazon S3 as a block device

Answer

Amazon EBS gp2 volumes

Question 9

A company is migrating a SAP system to AWS and needs to ensure that the SAP license is compliant. The current license is based on the number of users. What is the correct approach for SAP licensing on AWS?

Accepted Answer

Bring your own SAP license to AWS and ensure compliance with the user-based metric.. SAP licensing on AWS follows the same model as on-premises; the customer must license the SAP software based on users or engine size. Option A is wrong because AWS does not offer bring-your-own-license for all SAP products, but it is allowed. Option B is wrong because AWS does not include SAP licenses. Option D is wrong because AWS does not provide SAP licenses.

Answer

Purchase a SAP license through AWS Marketplace that is included in the EC2 instance cost.

Answer

Use AWS License Manager to track the number of vCPUs and report to SAP.

Answer

Use AWS License Manager to convert the user-based license to a processor-based license.

Question 10

A company is migrating a SAP system to AWS and needs to ensure that the database migration from SAP ASE to Amazon Aurora is successful with minimal downtime. Which AWS service should be used?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is the correct choice because it supports heterogeneous migrations from SAP ASE (Sybase) to Amazon Aurora with minimal downtime. DMS can continuously replicate ongoing changes from the source database to the target using change data capture (CDC), allowing the source system to remain operational during the migration and enabling a cutover with only a brief outage.

Question 11

A company is migrating a SAP system to AWS and wants to use AWS Systems Manager for patching. Which TWO prerequisites are required to use AWS Systems Manager Patch Manager?

Accepted Answer

The AWS Systems Manager Agent (SSM Agent) must be installed on the EC2 instance.. Option C is correct because Patch Manager relies on the AWS Systems Manager Agent (SSM Agent) running on the instance to receive and execute patch commands; without the SSM Agent installed and running, the instance cannot be managed by Systems Manager. Option D is correct because the instance needs an IAM instance profile/role granting Systems Manager permissions (e.g., the AmazonSSMManagedInstanceCore policy) so the agent can register with the service and retrieve patch baselines and commands. Option A is incorrect because instances in private subnets can be managed via SSM VPC endpoints or NAT, so a public subnet is not required. Option B is incorrect because Patch Manager supports multiple operating systems, including Windows Server and various Linux distributions, not just Amazon Linux 2. Option E is incorrect because a maintenance window is optional; patching can be run on demand via Run Command without configuring a maintenance window or reboot option.

Answer

The EC2 instance must be in a public subnet.

Answer

The EC2 instance must be running Amazon Linux 2.

Answer

A maintenance window must be configured with a reboot option.

Question 12

A company is migrating a multi-tier web application to AWS. The web tier uses sticky sessions. The application tier uses a shared session store. Which architecture ensures high availability and scalability?

Accepted Answer

Use an Application Load Balancer with sticky sessions and Amazon ElastiCache for session storage.. Using an Application Load Balancer (ALB) with sticky sessions and Amazon ElastiCache for session storage ensures high availability and scalability. Sticky sessions keep users on the same instance for session duration, while ElastiCache provides a shared, highly available session store that survives instance failures.

Answer

Use an Application Load Balancer with sticky sessions enabled, and store sessions on each EC2 instance.

Answer

Use a Classic Load Balancer with sticky sessions and store sessions in RDS.

Answer

Use Amazon CloudFront with origin failover and store sessions in S3.

Question 13

A company is migrating a custom CRM application to AWS. The application uses a PostgreSQL database. Which migration approach minimizes downtime?

Accepted Answer

Use AWS Database Migration Service (DMS) with ongoing replication (CDC).. AWS Database Migration Service (DMS) with ongoing change data capture (CDC) enables near-zero downtime migration by continuously replicating changes from the source to the target until cutover. Options B, C, and D all require taking the source database offline for backup or export, resulting in significant downtime.

Answer

Use AWS Backup to create a snapshot and restore to RDS.

Answer

Take a full backup of the source database, restore to RDS for PostgreSQL, and then cut over.

Answer

Use pg_dump to export the database and pg_restore to import into RDS.

Question 14

Which THREE factors should be considered when choosing a migration strategy for a legacy application to AWS? (Choose three.)

Accepted Answer

Total cost of ownership (TCO). Correct options: C, D, E. Total cost of ownership (TCO) is a key factor in migration decision-making. Business continuity requirements (RTO/RPO) ensure the application meets recovery objectives. Data sensitivity and compliance requirements dictate how data is handled during and after migration. Option A (Physical location) is less relevant because cloud migrations are not bound by physical location; servers can be migrated regardless of location. Option B (Programming language) alone does not determine the migration strategy; the application's architecture and dependencies are more important.

Answer

Physical location of the source server

Answer

Programming language used

Question 15

A company is migrating a large SAP ERP system to AWS. Which TWO AWS services are essential for high availability and disaster recovery? (Choose two.)

Accepted Answer

AWS Elastic Disaster Recovery (DRS). AWS Elastic Disaster Recovery (DRS) (option D) is correct because it provides block-level, continuous replication of on-premises or cloud SAP ERP servers into a low-cost staging area in AWS, enabling rapid recovery with minimal RPO/RTO during a disaster. Amazon Route 53 (option E) is correct because it delivers DNS-based high availability and failover, using health checks and routing policies such as failover or latency-based routing to redirect SAP clients to a healthy region or Availability Zone. Together they address the DR and HA requirements of a large SAP ERP migration. Amazon CloudWatch (A) is a monitoring and observability service, not a DR or HA mechanism, though it can trigger alarms. AWS Database Migration Service (B) is for migrating databases, not for ongoing high availability or disaster recovery. Amazon S3 (C) is object storage used for backups and data durability, but by itself it does not provide the automated server replication and DNS failover needed for SAP ERP HA/DR.

Answer

Amazon CloudWatch

Answer

AWS Database Migration Service

Answer

Amazon S3
