PAS-C01 Migration Practice Test 23 — 15 Questions

Question 1

A company is migrating SAP HANA to AWS and needs to ensure high availability. The database must be replicated synchronously across two Availability Zones with automatic failover. Which AWS service should be used?

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

Accepted Answer

SAP HANA System Replication (HSR) with Pacemaker. SAP HANA System Replication (HSR) with Pacemaker provides synchronous replication and automatic failover, making it the appropriate solution for high availability across Availability Zones. Amazon EBS Multi-Attach is incorrect because it is limited to a single AZ and not designed for SAP HANA replication. AWS DMS is for database migration, not ongoing HA. Amazon RDS Multi-AZ is for RDS databases and does not support SAP HANA.

Answer

Amazon EBS Multi-Attach volumes

Answer

AWS Database Migration Service (DMS)

Answer

Amazon RDS Multi-AZ deployment

Question 2

A company is migrating its SAP production system to AWS and needs to ensure that the migration does not exceed the allowed downtime window of 4 hours. The source database is 5 TB. Which migration strategy should be used?

Accepted Answer

Heterogeneous migration using AWS DMS with ongoing replication. Heterogeneous migration using AWS DMS with ongoing replication allows near-zero downtime by continuously replicating changes from the source to the target database during the migration, enabling a short cutover window. Option A is incorrect because homogeneous migration using AWS SCT and DMS is typically for same-database-engine migrations, but SCT is unnecessary for homogeneous, and the combination may not achieve the 4-hour window without ongoing replication. Option C is incorrect because AWS Snowball Edge is an offline data transfer method that involves shipping physical devices, which takes days to transfer 5 TB, exceeding the 4-hour window. Option D is incorrect because AWS Application Migration Service (MGN) is designed for server migration (rehosting), not database migration, and does not provide the database-level replication needed for this scenario.

Answer

Homogeneous migration using AWS Schema Conversion Tool (SCT) and AWS DMS

Answer

AWS Snowball Edge for offline data transfer

Answer

AWS Application Migration Service (MGN) replication

Question 3

A company is migrating SAP applications to AWS and needs to test the migration process without affecting the production environment. Which AWS service should be used to create an isolated test environment?

Accepted Answer

AWS CloudFormation. AWS CloudFormation (option D) allows you to create an isolated test environment using infrastructure as code (IaC) templates, enabling you to replicate the production setup without affecting the live environment. Option A is wrong because AWS CodePipeline is a CI/CD service for automating build, test, and deploy pipelines, not for creating test environments. Option B is wrong because AWS Service Catalog is for creating and managing catalogs of IT services, not for provisioning isolated test environments. Option C is wrong because AWS OpsWorks is a configuration management service using Chef and Puppet, not primarily for creating isolated test environments. Therefore, D is correct.

Answer

AWS CodePipeline

Answer

AWS Service Catalog

Answer

AWS OpsWorks

Question 4

A company is migrating SAP applications to AWS and needs to ensure that the migration complies with regulatory requirements for data encryption. Which TWO AWS services can be used to encrypt data at rest? (Choose TWO.)

Accepted Answer

Amazon EBS encryption. Amazon EBS encryption provides at-rest encryption for EBS volumes (Option C). AWS KMS (Key Management Service) manages the encryption keys used by EBS encryption and other AWS services (Option E). Options A and D are incorrect: AWS WAF is a web application firewall, not for data encryption; AWS CloudHSM provides hardware security modules for key storage but is not a direct service for encrypting data at rest. Option B (AWS Certificate Manager) is for SSL/TLS certificates, not data at rest encryption.

Answer

AWS WAF

Answer

AWS Certificate Manager (ACM)

Answer

AWS CloudHSM

Question 5

A company is migrating SAP to AWS and needs to set up connectivity between on-premises and AWS VPC with high bandwidth and low latency. Which TWO AWS services should be used? (Choose TWO.)

Accepted Answer

AWS Transit Gateway. AWS Direct Connect provides a dedicated network connection with high bandwidth and low latency, ideal for SAP migration. AWS Transit Gateway allows central management of connectivity between multiple VPCs and on-premises networks, simplifying network architecture. Options B, C, and D are incorrect: AWS Client VPN is for remote user access, not site-to-site; AWS VPN CloudHub connects multiple VPN connections but lacks dedicated bandwidth; AWS Site-to-Site VPN uses the public internet, which cannot guarantee the low latency and high bandwidth required for SAP workloads.

Answer

AWS Client VPN

Answer

AWS VPN CloudHub

Answer

AWS Site-to-Site VPN

Question 6

A company is migrating SAP HANA to AWS and needs to ensure that the database instances have high network throughput for replication traffic. Which THREE AWS features should be enabled? (Choose THREE.)

Accepted Answer

Placement Groups. Enhanced Networking provides higher network performance, Placement Groups provide low-latency network, and EBS-optimized instances provide dedicated bandwidth to EBS. Option D is wrong because Elastic IP does not improve throughput. Option E is wrong because VPC peering does not improve throughput, it connects VPCs.

Answer

Elastic IP addresses

Answer

VPC peering connections

Question 7

A company is migrating an SAP ERP system running on an on-premises IBM AIX server to AWS. The server hosts both the SAP application and the DB2 database. The company has a tight deadline and wants to minimize the migration effort. The current system uses a storage area network (SAN) with 2 TB of data. The company wants to use AWS native services and avoid re-architecting. What is the BEST migration strategy?

Accepted Answer

Use AWS Application Migration Service (MGN) to replicate the entire server to AWS.. AWS MGN supports migration of IBM AIX servers with block-level replication. Option B (manual install) is wrong because manual installation is more effort and not leveraging AWS services. Option C is wrong because AWS Snowball would require downtime and is not real-time. Option D is wrong because AWS DMS does not support DB2 on AIX as a source.

Answer

Manually install SAP and DB2 on EC2 and restore from backup.

Answer

Use AWS Snowball Edge to transfer the data offline and then launch EC2 instances.

Answer

Use AWS DMS to migrate the DB2 database to Amazon RDS for DB2.

Question 8

A company is migrating an SAP Business Warehouse (BW) system running on an on-premises HANA database to AWS. The migration must be completed with less than 1 hour of downtime. The source database is 3 TB. The company has established a 10 Gbps AWS Direct Connect connection. The SAP system uses a custom ABAP program that must be migrated as well. The company wants to minimize manual intervention. Which approach should be taken?

Accepted Answer

Set up SAP HANA System Replication (HSR) to replicate the database to AWS, then perform a takeover.. The correct approach is to use SAP HANA System Replication (HSR) to set up continuous replication from the on-premises HANA database to an SAP HANA database running on Amazon EC2. Once the systems are synchronized, a takeover can be performed with minimal downtime (seconds), meeting the <1 hour requirement. AWS DMS does not support SAP HANA as a source for ongoing replication without schema conversion, and Amazon RDS for HANA is not a supported target. Exporting and importing the database would require significant downtime due to the 3 TB data transfer and import time. AWS Application Migration Service (MGN) replicates the entire server, but for an SAP HANA database, HSR is a more appropriate and optimized method for database migration with minimal downtime.

Answer

Use AWS DMS to replicate the HANA database to Amazon RDS for HANA.

Answer

Export the HANA database to files, transfer via Direct Connect, and import on EC2.

Answer

Use AWS Application Migration Service (MGN) to replicate the entire server.

Question 9

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a 24-hour migration window. The company has a 1 Gbps dedicated connection to AWS. Which migration approach minimizes downtime?

Accepted Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication from the on-premises database to Amazon RDS.. AWS DMS with ongoing replication allows continuous data synchronization, minimizing downtime by enabling a cutover with minimal data loss. Option A is wrong because AWS SCT is for schema conversion, not data migration. Option B is wrong because a native Oracle export/import requires downtime for the export and import operations. Option D is wrong because AWS DataSync is for file-based data, not databases.

Answer

Use AWS Schema Conversion Tool (AWS SCT) to convert the schema and AWS DMS for full load only.

Answer

Use native Oracle Data Pump export and import to transfer the database over the dedicated connection.

Answer

Use AWS DataSync to copy the database files to Amazon S3, then restore to Amazon RDS.

Question 10

A company is migrating a legacy SAP ECC 6.0 system running on IBM AIX with DB2 to SAP S/4HANA on AWS. The current DB2 database is 4 TB and has extensive use of stored procedures and triggers. The migration window is 48 hours. Which migration strategy is MOST appropriate?

Accepted Answer

Use SAP Software Update Manager (SUM) with Database Migration Option (DMO) to migrate and convert to SAP HANA.. For migrating SAP ECC to S/4HANA with a database migration, SAP's Software Update Manager (SUM) with Database Migration Option (DMO) is the recommended tool. DMO performs both the software update (to S/4HANA) and the database migration (from DB2 to HANA) in a single process. Option B (AWS SMS) only replicates the server, not the database conversion. Option C (SLT) is for ongoing replication, not one-time migration. Option D (AWS DMS) does not support SAP-specific database objects like stored procedures and triggers.

Answer

Use AWS Server Migration Service (AWS SMS) to replicate the entire AIX server to AWS, then install SAP HANA.

Answer

Use SAP Landscape Transformation (SLT) to replicate data to SAP HANA in real time and then cut over.

Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication to migrate the database to SAP HANA.

Question 11

A company is migrating its SAP environment to AWS and wants to test the migration process before the final cutover. The company has a limited budget for the test environment. Which approach is MOST cost-effective?

Accepted Answer

Use AWS Elastic Disaster Recovery to replicate the on-premises servers to a staging area and launch test instances in a sandbox VPC.. AWS Elastic Disaster Recovery (AWS DRS) is the most cost-effective approach for testing SAP migration because it continuously replicates on-premises servers to a staging area with minimal resources, and allows launching test instances in an isolated sandbox VPC without affecting the source environment. This incurs low costs since staging resources are minimal and test instances are only launched temporarily. Option A is less cost-effective because DMS only handles database replication, not the full SAP system (OS, application, etc.), and a separate RDS instance still incurs costs. Option C is expensive as it requires provisioning full production-sized infrastructure. Option D is incorrect because Migration Hub is a tracking service and does not provide a sandbox for testing.

Answer

Use AWS Database Migration Service (AWS DMS) to continuously replicate the database to a smaller RDS instance for testing.

Answer

Provision a full production-sized infrastructure in a separate AWS account and use AWS DMS to replicate the database.

Answer

Use AWS Migration Hub to track the migration progress and perform a trial migration using AWS CloudFormation templates.

Question 12

A company is migrating its SAP HANA database from on-premises to AWS. The current system uses 6 TB of memory and the company wants to minimize downtime. The company has established a 10 Gbps AWS Direct Connect connection. Which migration method is MOST suitable?

Accepted Answer

Perform a full SAP HANA backup to the on-premises storage, copy the backup files to Amazon S3 using AWS Direct Connect, and restore on AWS.. SAP HANA backup and restore is a suitable method for migrating large databases like this 6 TB system. Using AWS Direct Connect at 10 Gbps provides high throughput for transferring backup files to Amazon S3, minimizing downtime. Option B (SAP HANA system replication) requires low latency and is typically used for high availability, not one-time migrations. Option C (AWS DMS) does not support SAP HANA as a source. Option D (AWS Snowball Edge) introduces logistical complexity and potential delays compared to a direct network transfer.

Answer

Set up SAP HANA system replication between on-premises and AWS, then perform a takeover.

Answer

Use AWS Database Migration Service (AWS DMS) with full load plus ongoing replication.

Answer

Use AWS Snowball Edge to physically transport the backup files to AWS and then restore.

Question 13

A company is migrating an SAP Business Suite system on Oracle to SAP S/4HANA on AWS. The migration involves a near-zero downtime requirement. The current system uses SAP Oracle on Linux. Which combination of tools should the company use?

Accepted Answer

Use SAP Software Update Manager (SUM) with the Database Migration Option (DMO) and the near-zero downtime option.. For migrating an SAP Business Suite on Oracle to SAP S/4HANA with near-zero downtime, the recommended tool is SAP Software Update Manager (SUM) with the Database Migration Option (DMO) and the near-zero downtime (NZDT) option. This allows for a combined system upgrade and database migration with minimal downtime. Option A is incorrect because AWS SCT is not designed for SAP HANA migrations. Option B is incorrect because AWS DMS does not support SAP HANA as a target. Option C is incorrect because SLT is used for data replication, not for system conversion or migration.

Answer

Use AWS Schema Conversion Tool (AWS SCT) and AWS Database Migration Service (AWS DMS) with ongoing replication.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the Oracle database to Amazon RDS for SAP HANA.

Answer

Use SAP Landscape Transformation (SLT) to replicate data to SAP HANA, then switch applications.

Question 14

A company needs to migrate its SAP application server from on-premises to AWS. The server runs on Windows Server 2012 R2 and has a custom SAP kernel. Which AWS service should be used to migrate the server with minimal changes?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) automates the lift-and-shift migration of servers from on-premises to AWS, supporting Windows Server and custom configurations such as SAP kernels. Option A (CloudEndure Migration) is wrong because CloudEndure has been superseded by AWS MGN and is no longer recommended for new migrations. Option B (AWS DMS) is wrong because it specializes in database migrations, not entire server instances. Option D (AWS SMS) is wrong because it is an older, less flexible service that may not handle custom kernels as effectively as MGN.

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Server Migration Service (AWS SMS)

Question 15

A company is migrating an SAP system to AWS and needs to ensure that the migration complies with regulatory requirements for data residency. The source system is in Germany and the target AWS Region is Frankfurt. Which step should be taken to address data residency?

Accepted Answer

Use AWS Artifact to review and accept the Data Processing Agreement (DPA) for the Frankfurt region.. AWS Artifact provides access to the Data Processing Agreement (DPA) for the Frankfurt region. Reviewing and accepting this DPA ensures contractual compliance with EU data residency requirements. Option B is incorrect because enabling cross-region replication to eu-west-1 (Ireland) would move data out of Frankfurt, violating data residency. Option C is incorrect because using AWS DMS with ongoing replication does not provide a contractual guarantee of data residency; it only enables data movement within or across regions. Option D is incorrect because AWS Config rules can monitor and alert on resource configurations but cannot enforce data residency at a contractual or legal level.

Answer

Enable cross-region replication to the eu-west-1 (Ireland) region for disaster recovery.

Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication to a secondary cluster in Frankfurt.

Answer

Configure AWS Config rules to prevent data from leaving the Frankfurt region.
