PAS-C01 Migration Practice Test 21 — 15 Questions

Question 1

A company is migrating its SAP system to AWS and wants to ensure that the migration does not violate any SAP licensing requirements. Which of the following is a correct licensing consideration?

Accepted Answer

SAP licenses must be purchased separately from SAP or an SAP partner. SAP requires that customers have proper licenses for all systems, including production and non-production, running on AWS. Option A is wrong because AWS does not provide SAP licenses by default. Option C is wrong because SAP licensing is based on the number of users or processor cores, not on the AWS account. Option D is wrong because SAP licensing is required for all environments.

Answer

SAP licenses are based on the number of AWS accounts used

Answer

SAP licenses are automatically included when you use AWS Launch Wizard

Answer

SAP licenses are not required for non-production environments in AWS

Question 2

A company is migrating its SAP ERP system to AWS and needs to minimize network latency between the SAP application servers and the database. Which architecture is recommended?

Accepted Answer

Place both the application and database servers in the same Availability Zone. Placing both the SAP application servers and the database in the same Availability Zone (AZ) minimizes network latency by keeping traffic within a single data center. Option A is incorrect because different AZs introduce additional latency due to inter-AZ data transfer. Option C is incorrect because different regions add significant latency and incur higher costs. Option D is incorrect because keeping the database on-premises introduces network latency over the internet or VPN connection.

Answer

Place the application servers in one AZ and the database in a different AZ

Answer

Place the application servers in one region and the database in another region

Answer

Keep the database on-premises and move only the application servers to AWS

Question 3

A company is migrating an SAP HANA system from on-premises to AWS. The HANA system uses a large amount of memory (2 TB). Which EC2 instance type is most suitable for this workload?

Accepted Answer

x2iedn.32xlarge. (x2iedn.32xlarge) is correct because it is a memory-optimized instance with up to 4 TB of memory, making it suitable for SAP HANA workloads requiring 2 TB of memory. Option B (c5n.18xlarge) is wrong because c5n instances are compute-optimized and have less memory. Option C (m5n.24xlarge) is wrong because m5n instances are general-purpose and cannot support 2 TB of memory. Option D (r5.24xlarge) is wrong because r5 instances have a maximum memory of 768 GB.

Answer

c5n.18xlarge

Answer

m5n.24xlarge

Answer

r5.24xlarge

Question 4

An organization is planning to migrate its SAP landscape to AWS and needs to ensure high availability for the SAP Central Services (ASCS) instance. Which TWO AWS services can be used to implement a high-availability architecture for ASCS?

Accepted Answer

Amazon EC2 Auto Recovery. Options A and E are correct. Amazon EC2 Auto Recovery can automatically restart an ASCS instance if it fails due to underlying hardware issues, providing a basic level of high availability. Amazon Route 53 can be configured with DNS failover to route traffic to a standby ASCS instance in another Availability Zone, enabling multi-AZ resilience. Option B (CloudFront) is a content delivery network and not designed for SAP ASCS HA. Option C (DMS) is a database migration service, irrelevant for ASCS. Option D (ELB) is typically not used for ASCS because ASCS requires a single active node with a virtual IP or DNS name, not load-balanced traffic.

Answer

Amazon CloudFront

Answer

AWS Database Migration Service (DMS)

Answer

Elastic Load Balancing (ELB)

Question 5

A company is migrating an SAP environment to AWS and needs to ensure that the SAP HANA database can be backed up efficiently. Which THREE AWS services can be used together to implement a backup strategy for SAP HANA?

Accepted Answer

Amazon EBS snapshots. The correct answers are B, D, and E. Amazon EBS snapshots provide point-in-time backups of SAP HANA data volumes. AWS Backup can automate and manage backup schedules for EBS snapshots and other resources. Amazon S3 can be used for long-term storage of backup files. Option A (Amazon RDS) is incorrect because SAP HANA is not an RDS database; it runs on EC2 with EBS volumes. Option C (Amazon DynamoDB) is a NoSQL database not used for SAP HANA backups.

Answer

Amazon RDS

Answer

Amazon DynamoDB

Question 6

A company is migrating its SAP system to AWS and needs to transfer a large amount of data (10 TB) from the on-premises data center to AWS. Which TWO AWS services can be used for this data transfer?

Accepted Answer

AWS DataSync. For large-scale data transfer (10 TB) to AWS, AWS DataSync (Option B) efficiently transfers data over the network with automation and optimization. AWS Snowball (Option D) is a physical device for offline transfer, ideal for large datasets when network transfer is impractical. Option A is incorrect because Amazon S3 Transfer Acceleration only speeds up S3 uploads over the internet, not a full migration service. Option C is incorrect because AWS CloudFormation is for infrastructure as code, not data transfer. Option E is incorrect because AWS DMS is for database migration, not general file transfer.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS CloudFormation

Answer

AWS Database Migration Service (DMS)

Question 7

The above IAM policy is attached to an IAM role used by an AWS DMS replication instance. The DMS task is migrating data from an on-premises Oracle database to Amazon S3. The DMS task fails with an access error. What is missing from the policy?

Accepted Answer

Permissions to pass the IAM role to the DMS replication instance are missing. The IAM policy attached to the role used by the DMS replication instance must include 'iam:PassRole' to allow DMS to pass the role to the replication instance. Without this permission, DMS cannot assume the role, leading to an access error. Option A is incorrect because EC2 describe permissions are not required for this migration. Option B is incorrect because the source is on-premises Oracle, not Amazon RDS. Option D is incorrect because the policy already includes S3 write permissions (implied by the context; the policy is not shown but the error is not about S3 access).

Answer

Permissions to describe EC2 instances are missing

Answer

Permissions to access Amazon RDS are missing

Answer

Permissions to write to the S3 bucket are missing

Question 8

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?

Accepted Answer

The source endpoint is not accessible from the replication instance. When the replication task status is 'running' but no data has been transferred after a significant period, it often indicates that the task is stuck in a preliminary validation phase. The most common reason is that the source endpoint is not accessible from the replication instance. The task may attempt to connect repeatedly without failing, hence the 'running' status. Insufficient memory (A) would typically cause performance degradation or errors, not a complete lack of transfer. A wrong target endpoint (C) would likely result in immediate task failure. Configuring HANA as a target (D) is irrelevant because HANA is the source in this migration.

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 9

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. For high availability, ASCS and ERS should be in different Availability Zones to avoid a single point of failure. Option B is wrong because the instance type is acceptable for a test environment. Option C is wrong because the AMI is not specified, but that is not the main issue. Option D is wrong because there is no security group defined, but that is a security issue, not an architectural HA issue.

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 10

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 Database Migration Service (DMS) supports heterogeneous migrations (e.g., from Oracle to Amazon Aurora) and can minimize downtime by using ongoing replication to keep the source and target synchronized during the migration. Option A is incorrect because AWS Backup is a backup/restore service, not a live migration tool, and typically requires downtime. Option B is incorrect because AWS Schema Conversion Tool (SCT) is used for schema conversion, not for the actual data migration; it is often used alongside DMS. Option C is incorrect because Amazon Redshift Spectrum is for querying data in Amazon S3, not for database migration.

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 11

A company is migrating a legacy SAP ECC 6.0 system to SAP S/4HANA on AWS. The current database is IBM Db2. Which AWS service should be used to assess the source system and plan the migration?

Accepted Answer

AWS Migration Evaluator. AWS Migration Evaluator (formerly TSO Logic) is the correct service for assessing the source SAP ECC 6.0 system and planning the migration to SAP S/4HANA. It provides a data-driven business case, including SAP-specific insights such as system sizing, licensing, and total cost of ownership. AWS Application Discovery Service is used for server-level discovery and dependency mapping, not SAP-specific assessment. AWS CloudEndure Migration is for lift-and-shift migration, not assessment. AWS Database Migration Service (DMS) is for migrating databases, not assessment.

Answer

AWS Application Discovery Service

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (DMS)

Question 12

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 13

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.. When a custom kernel parameter is not supported on the target EC2 instance, the recommended approach is to consult the SAP on AWS documentation for equivalent or alternative parameter settings that achieve the same effect within AWS's supported configurations. Option A is incorrect because disabling the parameter in the source before migration could affect the SAP system's performance or functionality during migration. Option B is incorrect because changing the EC2 instance type may not necessarily support the parameter, and it might introduce other compatibility issues. Option D is incorrect because proceeding with an unsupported kernel parameter could lead to system instability or failure on AWS.

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 14

A company is migrating an SAP ERP system to AWS. The SAP application servers use a shared /sapmnt filesystem. Which AWS storage solution is most suitable for this shared filesystem with high availability?

Accepted Answer

Amazon EFS. (Amazon EFS) is correct because Amazon EFS is a managed NFS filesystem that provides high availability and can be shared across multiple EC2 instances, making it suitable for the shared /sapmnt filesystem required by SAP. Option A (Amazon S3) is wrong because S3 is object storage, not a POSIX-compliant filesystem, and cannot be mounted as a shared filesystem. Option B (Amazon FSx for Windows File Server) is incorrect because SAP typically runs on Linux, and FSx for Windows is designed for Windows workloads. Option C (Amazon EBS with Multi-Attach) is not ideal because EBS Multi-Attach has limitations (max 16 instances, single Availability Zone) and is not as scalable or resilient as EFS for this use case.

Answer

Amazon S3 with a mount point

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with Multi-Attach enabled

Question 15

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 provides a single location to track migration progress across multiple AWS and partner tools, making it the appropriate service for managing migration project tasks and milestones. AWS Config (Option A) is for compliance and resource tracking, not migration management. AWS Systems Manager (Option B) is for operational management, not migration tracking. AWS CloudFormation (Option D) is for infrastructure as code. Therefore, Option C is correct.

Answer

AWS Config

Answer

AWS Systems Manager

Answer

AWS CloudFormation
