PAS-C01 Migration Practice Test 28 — 15 Questions

Question 1

The exhibit shows the output of the describe-replication-tasks command for an ongoing migration from SAP HANA to Amazon RDS for MySQL. The task status is 'running' but no data has been transferred after 2 hours. What is the most likely cause?

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

Accepted Answer

The source endpoint is not accessible from the replication instance. When a DMS replication task shows 'running' but no data has moved for hours, the most common cause is that the replication instance cannot reach the source endpoint — typically due to security group, NACL, routing, or DNS issues. DMS will keep the task in 'running' state while retrying the connection, so the symptom is a stalled task rather than an immediate failure.

Answer

The replication instance has insufficient memory

Answer

The target endpoint is pointing to the wrong database

Answer

The HANA database is not configured as a target

Question 2

The exhibit shows a CloudFormation template snippet for deploying SAP ASCS and ERS instances. Both instances are launched in the same subnet. What is the main architectural issue with this deployment?

Accepted Answer

Both instances are in the same Availability Zone, which defeats the purpose of high availability. SAP ASCS and ERS instances form a high-availability pair, and placing both in the same subnet means they reside in the same Availability Zone. If that AZ fails, both instances go down simultaneously, defeating the purpose of the ASCS/ERS failover architecture. Proper HA design requires the ASCS and ERS instances to be in separate AZs (or at minimum, the ERS on a separate host/AZ) so that a single AZ outage does not take out both.

Answer

The AMI ID is not specified correctly

Answer

The instance type m5.large is too small for SAP

Answer

No security group is defined, exposing the instances to the internet

Question 3

A company is migrating a monolithic application to AWS. The application has a relational database with complex queries and requires low-latency read replicas. Which database migration strategy minimizes downtime and supports heterogeneous migrations?

Accepted Answer

Use AWS Database Migration Service (DMS) with ongoing replication.. AWS DMS with ongoing replication minimizes downtime by continuously replicating data from the source to the target while the application remains operational. It supports heterogeneous migrations (e.g., Oracle to PostgreSQL) when combined with AWS SCT. This makes it the best choice for complex queries and low-latency read replicas on AWS.

Answer

Use AWS Backup to take a full backup and restore to Amazon RDS.

Answer

Use AWS Schema Conversion Tool (SCT) to convert the schema and perform a homogeneous migration.

Answer

Use Amazon Redshift Spectrum to query the data in place.

Question 4

A company wants to migrate a 50 TB SAP HANA database to AWS with minimal downtime. Which migration approach should be used?

Accepted Answer

Configure SAP HANA System Replication (HSR) between source and target.. SAP HANA System Replication (HSR) is the recommended method for migrating large HANA databases with minimal downtime, typically achieving near-zero downtime by replicating data continuously. Option B is incorrect because exporting the database to a file and uploading to S3 involves significant downtime for the export and restore process. Option C is incorrect because AWS SCT is used for schema conversion to different database engines, not for migrating HANA to HANA; converting to Aurora would change the database system and incur additional complexity and downtime. Option D is incorrect because AWS DMS does not support SAP HANA as a source for ongoing replication, and even if it did, HSR is more efficient for HANA-to-HANA migration.

Answer

Export the database to a file and upload to Amazon S3, then restore on RDS for HANA.

Answer

Use AWS SCT to convert the HANA schema to Aurora.

Answer

Use AWS DMS with ongoing replication from HANA to HANA.

Question 5

During a migration of an SAP system, the team notices that the source system uses a custom kernel parameter that is not supported on the target Amazon EC2 instance. What should the migration team do?

Accepted Answer

Consult the SAP on AWS documentation for equivalent parameter settings.. SAP on AWS has documented mappings and equivalents for kernel parameters that differ between on-premises systems and EC2 instances, so the correct action is to consult the SAP on AWS documentation for equivalent parameter settings. This ensures the target system is configured in a supported and certified manner rather than blindly copying or disabling parameters.

Answer

Disable the kernel parameter in the source before migration.

Answer

Change the EC2 instance type to one that supports the parameter.

Answer

Keep the same kernel parameter and proceed with the migration.

Question 6

An organization is planning a migration of SAP applications to AWS. Which AWS service should be used to track and manage the migration project's tasks and milestones?

Accepted Answer

AWS Migration Hub. AWS Migration Hub is the correct service because it provides a single location to track the progress of application migrations across multiple AWS and partner migration tools. It helps manage tasks and milestones by aggregating migration status and providing a dashboard. It is specifically designed for migration project tracking.

Answer

AWS Config

Answer

AWS Systems Manager

Answer

AWS CloudFormation

Question 7

A company is migrating an SAP Business Suite system to AWS. The source database is Oracle. The target is Amazon RDS for Oracle. Which AWS service should be used to automate the schema conversion and data migration?

Accepted Answer

Both AWS SCT and AWS DMS. Schema conversion is handled by AWS Schema Conversion Tool (SCT) and data migration with minimal downtime is handled by AWS Database Migration Service (DMS). Option A is wrong because SCT alone does not migrate data. Option C is wrong because AWS Application Discovery Service is used for discovery, not migration. Option D is wrong because DMS alone does not convert schemas.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Application Discovery Service

Answer

AWS Database Migration Service (DMS)

Question 8

A company is migrating an SAP system to AWS and needs to ensure that the target EC2 instances have the correct SAP kernel parameters. Which AWS service can be used to automate the configuration of these parameters?

Accepted Answer

AWS Systems Manager State Manager. AWS Systems Manager State Manager is designed to maintain EC2 instances in a defined state, including applying and enforcing configuration such as SAP kernel parameters via associations and documents. It can automate parameter changes across fleets, detect drift, and reapply the desired configuration, which is exactly what SAP kernel parameter management requires.

Answer

EC2 User Data scripts

Answer

AWS OpsWorks

Answer

AWS CloudFormation

Question 9

The exhibit shows the output of the describe-replication-tasks command. The task status is 'failed'. Which action should be taken to troubleshoot the failure?

Accepted Answer

Review the CloudWatch logs for the replication instance and task.. The first step is to check the CloudWatch logs for DMS to find detailed error messages. Option A is wrong because restarting without investigation may lead to the same error. Option B is wrong because modifying table mappings may not be the issue. Option C is wrong because creating a new task without understanding the failure is inefficient.

Answer

Restart the replication task with a different migration type.

Answer

Modify the table mappings to exclude all tables.

Answer

Create a new replication task with the same settings.

Question 10

The exhibit shows a CloudFormation template snippet. During migration, the SAP application server fails to start because the root volume is too small. What is the most efficient fix?

Accepted Answer

Modify the template to increase VolumeSize to 100 and update the stack.. The root volume size is defined in the CloudFormation template as a parameter or resource property. The most efficient and idempotent fix is to modify the template's VolumeSize value and run a stack update, which keeps the infrastructure defined as code and avoids drift. This ensures the change is reproducible and tracked in version control.

Answer

Manually resize the EBS volume via the AWS Console and then update the stack.

Answer

Stop the instance, modify the volume size, and start the instance.

Answer

Delete the stack and create a new one with a larger volume.

Question 11

Which THREE factors should be considered when selecting an EC2 instance type for an SAP HANA production system during migration? (Choose 3.)

Accepted Answer

Memory (RAM) size relative to the HANA workload. Option A is correct because SAP HANA is an in-memory database, so the EC2 instance must provide enough RAM to hold the entire working dataset in memory, making memory size relative to the HANA workload a primary sizing factor. Option D is correct because HANA production systems depend heavily on fast, low-latency networking for node-to-node communication, replication, and storage access, so network throughput and latency must be evaluated. Option E is correct because SAP only supports HANA on specific certified instance types and sizes, so selecting an SAP-certified EC2 instance is mandatory for a production deployment. Option B is not required because SAP HANA is a CPU- and memory-intensive in-memory database, not a GPU-accelerated workload, so GPU capabilities are irrelevant for standard HANA sizing. Option C is not a primary selection factor because EBS optimization is a storage/network performance characteristic that many instance families already provide, but it does not by itself determine whether an instance type is suitable for an SAP HANA production system.

Answer

GPU acceleration capabilities

Answer

EBS-optimized by default

Question 12

Which TWO AWS services can be used to automate the deployment of SAP infrastructure during migration? (Choose 2.)

Accepted Answer

AWS Service Catalog. AWS Service Catalog (B) is correct because it lets organizations create and govern pre-approved, standardized product portfolios — including SAP infrastructure templates — so migration teams can provision compliant SAP environments on demand with a single, repeatable action. AWS CloudFormation (C) is correct because it is the native infrastructure-as-code service that automates the deployment of SAP infrastructure by defining EC2 instances, EBS volumes, VPC networking, security groups, and SAP-specific parameters in templates that can be versioned and re-deployed consistently. Together these services directly automate SAP infrastructure provisioning during a migration. AWS OpsWorks (A) is a configuration-management service built around Chef/Puppet stacks and is not the primary tool for automating SAP infrastructure deployment; AWS Elastic Beanstalk (D) targets application deployment for web apps, not SAP infrastructure; and AWS CodePipeline (E) is a CI/CD orchestration service that coordinates build and release stages but does not itself deploy SAP infrastructure.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodePipeline

Question 13

A company is migrating an on-premises SAP ERP system to AWS. The system uses a large Oracle database. The migration must minimize downtime. Which AWS service should be used for the database migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can migrate databases with minimal downtime by using ongoing replication. Option A is incorrect because AWS SMS is designed for server migration, not database migration. Option B is incorrect because AWS Application Migration Service (MGN) is also for server migration. Option C is incorrect because AWS Schema Conversion Tool (SCT) assists with schema and code conversion but is not a full database migration service. Option D is correct because AWS Database Migration Service (DMS) can migrate Oracle databases to AWS with minimal downtime using continuous replication.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Application Migration Service (MGN)

Answer

AWS Schema Conversion Tool (SCT)

Question 14

A company is migrating its SAP landscape to AWS and has a requirement to use existing software licenses to reduce costs. Which AWS pricing model should be used?

Accepted Answer

Dedicated Hosts. Dedicated Hosts provide a physical server dedicated to a single customer, which allows you to use your existing software licenses, including Windows Server and SQL Server, and also SAP licenses that are tied to physical cores or sockets. This helps reduce costs by leveraging bring-your-own-license (BYOL).

Answer

Compute Savings Plans

Answer

Reserved Instances (RI)

Answer

Dedicated Instances

Question 15

A company is migrating SAP applications to AWS and needs to replicate data from on-premises Active Directory to AWS Managed Microsoft AD for authentication. Which AWS service should be used?

Accepted Answer

AWS Directory Service for Microsoft Active Directory. AWS Directory Service for Microsoft Active Directory (also known as AWS Managed Microsoft AD) is a managed service that allows you to run Microsoft Active Directory in the AWS cloud. It supports trust relationships with on-premises AD, enabling replication of users and groups for authentication. This is the correct service for replicating on-premises AD to AWS for authentication.

Answer

AWS Transit Gateway

Answer

AWS Resource Access Manager (RAM)

Answer

AWS AD Connector
