PAS-C01 Migration Practice Test 25 — 15 Questions

Question 1

A company is migrating its SAP application from on-premises to AWS. The migration plan includes rehosting the SAP application servers and re-platforming the database to Amazon RDS for SAP. Which AWS service should the company use to automate the deployment of SAP application servers?

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

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP (Option B) is a service that automates the deployment of SAP infrastructure, including application servers. Option A (AWS OpsWorks) is for configuration management with Chef/Puppet, not SAP-specific. Option C (Amazon EC2 Auto Scaling) handles scaling, not initial deployment. Option D (AWS CloudFormation) is a general infrastructure-as-code tool but lacks SAP-specific guidance.

Answer

AWS OpsWorks

Answer

Amazon EC2 Auto Scaling

Answer

AWS CloudFormation

Question 2

A company is migrating an SAP BusinessObjects environment to AWS. The migration must ensure that the legacy reporting system remains accessible during the transition. Which AWS service can help facilitate this by allowing the company to redirect traffic gradually?

Accepted Answer

Amazon Route53 with weighted routing policies. Amazon Route53 with weighted routing policies can gradually shift traffic from on-premises to AWS by assigning weights to DNS records. Option A (Amazon CloudFront) is a content delivery network, not for traffic shifting. Option B (Elastic Load Balancer) distributes traffic within AWS, not for gradual migration. Option C (AWS Global Accelerator) improves performance but does not provide weighted routing. Option D (Amazon Route53 with weighted routing policies) is correct because it allows incremental traffic redirection during migration.

Answer

Amazon CloudFront

Answer

Elastic Load Balancer (ELB)

Answer

AWS Global Accelerator

Question 3

A company is migrating an SAP HANA system to AWS using a homogeneous copy. The source database is SAP HANA 2.0 on SUSE Linux, and the target is also SAP HANA 2.0 on AWS. Which AWS service can be used to transfer the HANA backup files to Amazon S3 efficiently?

Accepted Answer

AWS DataSync. AWS DataSync is designed for efficient, automated data transfer between on-premises storage and Amazon S3, including large files like SAP HANA backups. It accelerates transfers, performs integrity checks, and can be scheduled. This makes it ideal for transferring HANA backup files to S3.

Answer

AWS Storage Gateway

Answer

AWS Direct Connect

Answer

Amazon S3 Transfer Acceleration

Question 4

A company is migrating an SAP NetWeaver system to AWS using the AWS Application Migration Service (AWS MGN). The source server runs SUSE Linux Enterprise Server (SLES) 12 SP5. After the cutover, the SAP application fails to start with an error indicating that the hostname resolution fails. The target EC2 instance has the same hostname as the source. What is the most likely cause?

Accepted Answer

The /etc/hosts file on the target instance still references the source server's old private IP address. After cutover, the target instance may have an /etc/hosts file that still points the hostname to the source server's old private IP address. Since the hostname is the same, the SAP application tries to resolve it, but the IP is no longer valid, causing hostname resolution failure. Updating /etc/hosts with the new IP or removing the entry resolves the issue.

Answer

The network configuration file /etc/sysconfig/network was not replicated

Answer

The source server's operating system is not supported by AWS MGN

Answer

The target instance is not registered in Amazon Route 53 private hosted zone

Question 5

A company is migrating an SAP ERP system to AWS. The SAP system uses a central instance (CI) and dialog instances. The migration must minimize downtime. Which AWS service should be used to replicate the application servers in near real-time?

Accepted Answer

AWS Elastic Disaster Recovery (AWS DRS). AWS Elastic Disaster Recovery (AWS DRS) provides continuous, block-level replication of on-premises or cloud servers to AWS with near-real-time RPO (seconds) and low-cost staging areas. For SAP application servers (central instance and dialog instances), DRS replicates the entire server so it can be launched as EC2 instances during failover, minimizing downtime during migration.

Answer

Amazon S3 Replication

Answer

AWS DataSync

Answer

AWS Backup

Question 6

A company is migrating an SAP HANA database to AWS using the SAP HANA System Replication (HSR) with asynchronous mode. The database size is 5 TB. The migration must be completed within 8 hours. Which AWS resource is most critical to ensure the initial data synchronization completes within the time window?

Accepted Answer

EC2 instance with high network bandwidth and Enhanced Networking. The initial data synchronization in SAP HANA System Replication (HSR) is network-intensive, as it transfers the full 5 TB database from the source to the target. High network bandwidth (e.g., using Enhanced Networking with ENA) directly reduces transfer time, making it the most critical resource to meet the 8-hour window. While EBS gp3 volumes (Option C) provide sufficient IOPS, they are secondary because the bottleneck is network throughput, not storage performance. Option B (EBS snapshots) is not used in HSR, and Option D (S3 multipart upload) is irrelevant for HSR.

Answer

EBS snapshots for the initial data copy

Answer

EBS gp3 volumes with sufficient IOPS

Answer

Amazon S3 multipart upload for initial data

Question 7

A company is migrating its SAP system to AWS and needs to assess the current on-premises environment for compatibility. Which AWS tool should be used to collect system configuration and usage data for SAP systems?

Accepted Answer

AWS Application Discovery Service. AWS Application Discovery Service (option A) is the correct tool for collecting system configuration and usage data from on-premises environments, including SAP systems, to inform migration planning. AWS Migration Hub (option B) tracks migration progress across tools but does not perform data collection. AWS Systems Manager (option C) is for management and operations, not discovery. AWS Server Migration Service (option D) automates server replication but does not collect configuration or usage data.

Answer

AWS Migration Hub

Answer

AWS Systems Manager

Answer

AWS Server Migration Service (AWS SMS)

Question 8

A company is migrating an SAP Business Suite system to AWS. The system runs on AIX on IBM Power Systems. The company wants to rehost the system on AWS using a lift-and-shift approach. Which AWS service can replicate the AIX operating system to run on AWS?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) supports agent-based migration for AIX via the AWS Replication Agent. Option A (AWS CloudEndure Migration) has been rebranded as AWS MGN. Option B (AWS SMS) does not support AIX. Option C (AWS Database Migration Service) is for databases, not OS.

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Server Migration Service (AWS SMS)

Question 9

A company is migrating an SAP system to AWS and wants to use an existing AWS Direct Connect connection for data transfer. The migration involves transferring 10 TB of data. Which AWS service is designed to accelerate data transfer over Direct Connect?

Accepted Answer

AWS DataSync. AWS DataSync is designed to accelerate data transfer over Direct Connect by optimizing network usage, performing automatic encryption, and managing retries. Amazon S3 Transfer Acceleration (Option A) is optimized for transfers over the internet using AWS edge locations, not Direct Connect. AWS VPN (Option B) provides a secure tunnel but does not accelerate bulk transfers. AWS Snowball (Option D) is an offline physical device, not for use with Direct Connect.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS VPN

Answer

AWS Snowball

Question 10

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a 4-hour maintenance window. Which AWS service should be used to minimize downtime during the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports ongoing replication to minimize downtime. Option A (AWS Server Migration Service) is for server-level migrations. Option C (AWS Data Pipeline) is for data processing. Option D (AWS Snowball) is for large data transfers but not minimal downtime.

Answer

AWS Server Migration Service

Answer

AWS Data Pipeline

Answer

AWS Snowball

Question 11

A company is migrating a large SAP HANA system to AWS. The SAP system has strict latency requirements for storage and requires high IOPS. Which storage solution should be used for the SAP HANA data volume?

Accepted Answer

Amazon EBS io2 Block Express volumes. SAP HANA on AWS requires high-performance storage with high IOPS and sub-millisecond latency. Amazon EBS io2 Block Express volumes provide up to 256K IOPS and sub-millisecond latency, making them the appropriate choice for the SAP HANA data volume. Option A (Amazon S3) is object storage, not block storage, and is unsuitable for database volumes. Option C (Amazon EFS) is file storage, also not block storage. Option D (Amazon EBS gp3 volumes) is general purpose SSD but does not match the performance of io2 Block Express for HANA workloads.

Answer

Amazon S3

Answer

Amazon EFS

Answer

Amazon EBS gp3 volumes

Question 12

A company is migrating an SAP environment to AWS using a heterogeneous database migration from Oracle to SAP HANA. The migration tool must convert the database schema and data types. Which AWS service or feature should be used?

Accepted Answer

AWS Database Migration Service (DMS) with AWS Schema Conversion Tool (SCT). AWS Database Migration Service (DMS) combined with the AWS Schema Conversion Tool (SCT) is the correct choice because SCT performs the heterogeneous schema and data-type conversion from Oracle to SAP HANA, while DMS handles the actual data migration with minimal downtime. This pairing is specifically designed for cross-engine migrations where the source and target database platforms differ. AWS Server Migration Service is for migrating on-premises servers/VMs to EC2, not for database schema conversion. AWS Data Pipeline is an orchestration service for data workflows and does not convert schemas or data types. SAP HANA Studio is a client administration/development tool, not a migration service for converting Oracle schemas.

Answer

AWS Server Migration Service

Answer

AWS Data Pipeline

Answer

SAP HANA Studio

Question 13

A company is migrating its SAP landscape to AWS and plans to use an SAP HANA multi-node scale-out configuration. Which THREE considerations are important for the network design?

Accepted Answer

Use a placement group to ensure nodes are in close proximity. Option A is correct because SAP HANA scale-out nodes exchange frequent, latency-sensitive data (for example, during distributed query processing and table redistribution), and an AWS cluster placement group packs the instances close together within a single Availability Zone to provide low-latency, high-throughput networking. Option B is correct because SAP recommends isolating HANA inter-node communication on a dedicated network interface so that the high-volume internode traffic does not contend with client, application, or storage traffic, which AWS supports by attaching multiple ENIs to an instance. Option E is correct because SAP HANA scale-out requires very low round-trip latency between all nodes (SAP guidance targets well under 1 ms RTT, with AWS cluster placement groups typically delivering single-digit microseconds), and exceeding this degrades or invalidates the certified scale-out performance. Option C is not appropriate because a NAT Gateway is used for outbound internet access from private subnets, not for node-to-node traffic within the cluster. Option D is not appropriate because inter-node communication should use private IP addresses inside the VPC for security and performance, not public IPs.

Answer

Use a NAT Gateway for inter-node traffic

Answer

Use public IP addresses for inter-node communication

Question 14

Refer to the exhibit. An administrator is creating an IAM policy for a user who will manage SAP application servers during migration. The policy currently allows starting and stopping EC2 instances. What additional permission is required to allow the user to terminate instances?

Accepted Answer

ec2:TerminateInstances. ec2:TerminateInstances. In AWS IAM, each EC2 API action maps to a specific permission, and terminating an instance is controlled by the ec2:TerminateInstances action. Since the policy already allows starting and stopping instances (ec2:StartInstances and ec2:StopInstances), adding ec2:TerminateInstances is the only way to grant the user the ability to permanently delete instances. This is essential for managing SAP application servers during migration, where decommissioning old instances is a common task.

Answer

ec2:ModifyInstanceAttribute

Answer

ec2:RebootInstances

Answer

ec2:DeleteInstances

Question 15

Refer to the exhibit. An SAP HANA system is running on an EC2 instance with the attached volumes shown. The HANA system requires high IOPS for its data volume. Which volume should be used for the HANA data directory?

Accepted Answer

vol-1a2b3c4d5e6f78901 (io1). The io1 volume is correct because SAP HANA's data directory demands consistently high IOPS, and io1 (Provisioned IOPS SSD) allows you to provision a specific IOPS level independent of volume size, which is essential for HANA's random read/write workload. gp3, while flexible, has a baseline of 3,000 IOPS and only scales IOPS separately up to 16,000, but for production HANA workloads requiring guaranteed high IOPS, io1 (or io2) is the AWS-recommended choice. Striping both volumes would mix a lower-performance gp3 into the data path, and instance store is ephemeral and not suitable for persistent HANA data.

Answer

Both volumes for striping

Answer

vol-0a1b2c3d4e5f67890 (gp3)

Answer

Neither volume; use instance store
