PAS-C01 Migration Practice Test 16 — 15 Questions

Question 1

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?

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

Accepted Answer

The /etc/hosts file on the target instance still references the source server's old private IP address. AWS MGN replicates the entire disk, including the /etc/hosts file. After cutover, the target EC2 instance gets a new private IP address, but the /etc/hosts file still contains the source server's old private IP. This causes hostname resolution to fail because the SAP application tries to resolve the hostname to the old IP. Option A is incorrect because /etc/sysconfig/network is not directly related to hostname resolution failure. Option C is incorrect because SLES 12 SP5 is supported by AWS MGN. Option D is incorrect because Route 53 private hosted zone is not required for hostname resolution if /etc/hosts is correctly configured.

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 2

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 (DRS) provides continuous replication of block-level data, enabling near real-time replication of application servers. Option A (AWS Backup) is for scheduled backups, not real-time replication. Option B (AWS DataSync) is for one-time data transfers. Option D (Amazon S3 replication) is for S3 objects.

Answer

Amazon S3 Replication

Answer

AWS DataSync

Answer

AWS Backup

Question 3

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 4

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 5

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 6

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 7

A company is migrating an SAP HANA system to AWS using SAP HANA System Replication (HSR). The migration must have a Recovery Point Objective (RPO) of less than 15 minutes and a Recovery Time Objective (RTO) of less than 2 hours. Which TWO actions should the company take to meet these objectives?

Accepted Answer

Deploy the target system in a different Availability Zone. To meet an RPO of less than 15 minutes and an RTO of less than 2 hours for an SAP HANA migration using HSR, the company should deploy the target system in a different Availability Zone (option A) and configure SAP HANA System Replication in synchronous mode (option E). Synchronous replication ensures that data is written to both source and target before the transaction is committed, providing near-zero RPO. In the event of a failure, the target can be promoted quickly, meeting the RTO of under 2 hours. Option B (using EBS snapshots) would not achieve the required RPO as snapshots are periodic and not continuous. Option C (placing the target in a different region) would introduce higher latency and potential RPO/RTO challenges. Option D (single Availability Zone) does not provide redundancy and would increase risk.

Answer

Use Amazon EBS snapshots for data replication

Answer

Place the target system in a different AWS Region

Answer

Use a single Availability Zone for both source and target

Question 8

A company is migrating an SAP ERP system to AWS using the SAP Landscape Virtualization Management (LVM) tool. The migration must comply with SAP's 'bring your own license' (BYOL) model. Which THREE steps should the company take to ensure compliance?

Accepted Answer

Decommission the source system after successful migration. Options B, C, and D are correct. During an SAP migration to AWS using SAP LVM, the system copy functionality (Option C) automates the creation of the target system. Because SAP license keys are hardware-dependent, new license keys must be generated for the AWS instances (Option D). After a successful migration, the source system must be decommissioned to comply with SAP's BYOL model (Option B). Option A is incorrect because AWS License Manager is not designed for SAP license tracking; SAP license management is handled through SAP's own tools. Option E is incorrect because using the same IP address is not required and often impractical in AWS.

Answer

Use AWS License Manager to track SAP licenses

Answer

Configure the target system with the same IP address as the source

Question 9

A company is planning to migrate an SAP HANA database to AWS. Which THREE factors should the company consider when selecting an EC2 instance type for the SAP HANA database?

Accepted Answer

The instance must be EBS-optimized. For SAP HANA on AWS, EC2 instance types must be memory-optimized (e.g., r5, r6i, x1e) and listed in the SAP Certified Instance Types for SAP HANA. Additionally, instances must be EBS-optimized to provide dedicated bandwidth to EBS volumes. Burstable performance (option A) is not suitable for SAP HANA's consistent performance requirements. While the Nitro System (option C) is recommended, it is not a strict requirement.

Answer

The instance type must support burstable performance

Answer

The instance must be based on the AWS Nitro System

Question 10

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 its SAP system to AWS and needs to maintain compliance with regulatory requirements that mandate data encryption at rest. Which AWS service should be used to manage encryption keys for Amazon EBS volumes?

Accepted Answer

AWS Key Management Service (KMS). WS Key Management Service (KMS). KMS is used to create and control encryption keys for encrypting Amazon EBS volumes. Option A (AWS Secrets Manager) is for managing secrets like database credentials, not encryption keys. Option B (AWS Certificate Manager) handles SSL/TLS certificates. Option D (AWS CloudHSM) provides hardware security modules but is more complex and typically used for specific compliance needs; KMS is the standard service for managing EBS encryption keys.

Answer

AWS Secrets Manager

Answer

AWS Certificate Manager (ACM)

Answer

AWS CloudHSM

Question 13

A company is migrating a large SAP ERP system to AWS. The system has multiple interfaces with external systems using RFC connections. During the migration, the team needs to minimize changes to the external systems' configurations. What approach should be taken for the RFC connections?

Accepted Answer

Assign an Elastic IP address to the SAP application server. Assigning an Elastic IP address to the SAP application server ensures that the public IP address remains the same after migration, so external systems do not need to update their RFC connection configurations. Option A (changing external systems to use DNS names) would require changes to external systems, which contradicts the goal of minimizing changes. Option B (using the private IP) would not be reachable from external systems over the internet. Option C (NAT Gateway) is used for outbound traffic, not for inbound RFC connections. Option D (Elastic IP) correctly provides a static public IP address for inbound RFC traffic.

Answer

Change the external systems to use DNS names instead of IP addresses

Answer

Use the private IP address of the EC2 instance

Answer

Use a NAT Gateway to route the RFC traffic

Question 14

A company is planning to migrate its SAP system to AWS and wants to test the migration process with a smaller system first. Which AWS service can be used to create a pre-configured SAP environment for testing?

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP provides a guided way to deploy SAP systems on AWS, including pre-configured environments, making it ideal for testing migrations. Option A (AWS Service Catalog) is for IT governance and not SAP-specific. Option B (AWS Quick Starts) are templates but not pre-configured for SAP. Option D (AWS CloudFormation) is infrastructure as code but lacks SAP-specific pre-configuration.

Answer

AWS Service Catalog

Answer

AWS Quick Starts

Answer

AWS CloudFormation

Question 15

A company is migrating an SAP system to AWS and needs to ensure backup compliance. The SAP database is SAP HANA. Which TWO AWS services can be used to back up SAP HANA databases?

Accepted Answer

Backint agent for SAP HANA. AWS Backup (option E) provides a fully managed backup service that can automate and centrally manage backups of SAP HANA databases. The Backint agent for SAP HANA (option A) is an SAP-certified backup integration that allows HANA to directly stream backups to Amazon S3, and it integrates with AWS Backup for scheduling and retention. Option B (Amazon S3 lifecycle policies) is a storage management feature, not a backup service. Option C (AWS Storage Gateway) enables hybrid cloud storage but does not provide native backup capabilities for SAP HANA. Option D (AWS Database Migration Service) is used for database migrations, not backups.

Answer

Amazon S3 lifecycle policies

Answer

AWS Storage Gateway

Answer

AWS Database Migration Service (DMS)
