PAS-C01 Migration Practice Test 14 — 15 Questions

Question 1

A company is migrating a large SAP S/4HANA system (8 TB total data, high I/O) from on-premises to AWS. The SAP system runs on HANA database and uses a three-tier architecture with application servers and database servers. The migration plan must minimize downtime and ensure data consistency. The company has a 10 Gbps direct connection to AWS. They have considered using AWS DMS, but the database is SAP HANA, which is not supported as a source by DMS. The migration team needs to transfer the HANA database and also the application files. They also need to replicate ongoing changes to minimize downtime. Which combination of AWS services should the migration team use? (Choose the best answer.)

Accepted Answer

Use AWS Application Migration Service (MGN) for the application servers. Use HANA Backint agent to back up the database to S3 and perform incremental backups for ongoing replication.. AWS DataSync can transfer large files efficiently over Direct Connect. HANA database backup to S3 using Backint allows incremental backups and can be used with S3 for ongoing replication. AWS HANA replication is not a service; SAP HANA system replication is a feature. AWS MGN can replicate the entire server including OS and application. The best combination is to use MGN for the application servers and Backint to S3 for HANA database backup and recovery. Option C is correct. Option A is not suitable because DMS cannot migrate HANA. Option B is not efficient for ongoing replication. Option D includes AWS DMS which is not supported.

Answer

Use AWS DataSync to copy the entire HANA database files (data and log volumes) and application files to AWS. Then restore from the copied files.

Answer

Use AWS Database Migration Service (DMS) with SAP HANA as a source by installing a custom connector. Use AWS DataSync for application files.

Answer

Use AWS DMS for the HANA database using a homogeneous migration. Use AWS MGN for the application servers.

Question 2

A company is migrating its SAP ERP system (with Oracle database) to AWS using the SAP-certified approach. The current on-premises environment uses Oracle RAC for high availability. The company wants to reduce licensing costs and simplify the architecture on AWS. Which of the following is the MOST efficient migration strategy?

Accepted Answer

Use AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance. Use AWS MGN for the application servers.. AWS does not support Oracle RAC in a fully supported manner for SAP. The best practice is to migrate to Amazon RDS for Oracle or use Oracle single instance on EC2. Using AWS DMS with ongoing replication can minimize downtime. Option B is correct because it uses DMS and moves to RDS, which reduces licensing overhead. Option A uses RAC which is not recommended on AWS. Option C uses DMS but then keeps RAC, which is costly and unsupported. Option D uses DataSync which is not for database replication.

Answer

Use AWS DMS to migrate the database to Amazon RDS for Oracle, but then configure RDS for Oracle RAC.

Answer

Use AWS DataSync to copy the Oracle database files to EBS volumes, then restore on an EC2 instance.

Answer

Lift-and-shift the Oracle RAC cluster to EC2 using AWS Application Migration Service.

Question 3

A company is migrating its SAP Business Suite system from on-premises to AWS. The system uses a Sybase ASE database. The migration team has limited Sybase expertise. They want to minimize the operational overhead after migration. Which database migration approach should they choose?

Accepted Answer

Use SAP Software Update Manager (SUM) with Database Migration Option (DMO) to migrate the system to SAP HANA on EC2.. SAP supports Sybase ASE to SAP HANA migration as part of SAP Business Suite on HANA. Migrating to SAP HANA on AWS is a strategic move and reduces complexity. Using DMS for Sybase to RDS for Sybase is possible but Sybase ASE on RDS is not a managed service; it's an EC2-based deployment. Option C is correct because moving to HANA is a common SAP migration path and reduces overhead. Option A is wrong because DMS cannot migrate to Sybase on RDS (RDS supports Sybase? Actually RDS does not support Sybase; only EC2). Option B is wrong because using AWS MGN for the database server retains Sybase on EC2, not reducing overhead. Option D is wrong because DataSync is not for database replication.

Answer

Use AWS MGN to replicate the entire Sybase server to EC2, then perform a system upgrade to SAP HANA.

Answer

Use AWS DataSync to copy the Sybase data files to EBS and attach to an EC2 instance running Sybase.

Answer

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

Question 4

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database size is 500 GB, and the network bandwidth between the on-premises data center and AWS is 100 Mbps. The migration must minimize downtime. Which AWS service should the company use for the initial data load?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can perform a full load and then continuously replicate changes to minimize downtime. AWS Snowball is for large offline data transfer, but the network might be sufficient; however, DMS is the recommended migration service for databases. Option B (AWS Database Migration Service) is correct because it supports ongoing replication to reduce downtime. Option A (AWS Snowball) is for offline transfer, not minimal downtime with continuous replication. Option C (AWS S3 Transfer Acceleration) is for file transfers, not database migration. Option D (AWS Direct Connect) improves network but does not perform data migration.

Answer

AWS Snowball

Answer

AWS Direct Connect

Answer

AWS S3 Transfer Acceleration

Question 5

A company is migrating an SAP HANA database from on-premises to AWS. The current system uses 8 TB of data. The migration must be completed within a 4-hour downtime window. The network link has 1 Gbps throughput. What is the MOST efficient migration strategy?

Accepted Answer

Use AWS Snowball Edge to transfer the data offline. At 1 Gbps, transferring 8 TB over the network would take approximately 18 hours (8 TB * 1024 GB/TB * 8 bits/byte / 1 Gbps = 65536 seconds = ~18 hours), exceeding the 4-hour window. AWS Snowball Edge can transport 8 TB offline. Option B (AWS Snowball Edge) is correct. Option A (AWS DMS) would not meet the time constraint. Option C (AWS MGN) is for server migration, not database. Option D (Direct Connect) still has the same bandwidth limitation.

Answer

Use AWS Database Migration Service (DMS) with ongoing replication

Answer

Use AWS Direct Connect to increase bandwidth

Answer

Use AWS Application Migration Service (MGN)

Question 6

A company is migrating its SAP landscape to AWS and plans to use SAP S/4HANA. The migration includes a heterogeneous system conversion from an existing SAP ECC system. Which AWS service or tool supports the generation of the migration cockpit and migration object modeler content required for the conversion?

Accepted Answer

SAP S/4HANA Migration Cockpit (not an AWS service). SAP S/4HANA migration uses the SAP S/4HANA Migration Cockpit, which relies on migration object modeler content. This content is generated by the SAP S/4HANA Migration Cockpit itself, not by an AWS service. AWS does not provide a service that generates SAP migration content. Option A (AWS Migration Hub) tracks migrations. Option B (AWS Application Migration Service) is for server migration. Option C (AWS Database Migration Service) migrates databases. Option D (SAP S/4HANA Migration Cockpit) is the correct tool for generating the migration cockpit content.

Answer

AWS Database Migration Service (DMS)

Answer

AWS Application Migration Service (MGN)

Answer

AWS Migration Hub

Question 7

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?

Accepted Answer

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

Answer

AWS OpsWorks

Answer

Amazon EC2 Auto Scaling

Answer

AWS CloudFormation

Question 8

A company is migrating its SAP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS). The solution must support automatic failover in the event of an instance failure. Which AWS architecture meets these requirements?

Accepted Answer

Deploy two EC2 instances in different Availability Zones with a shared Amazon EFS filesystem and use Route53 health checks for failover. SAP ASCS high availability on AWS is achieved using a cluster spanning two Availability Zones with a shared EFS filesystem for the /sapmnt and /usr/sap/trans directories. AWS does not support cluster-based floating IPs, so Route53 health checks are used for failover. Option A (Multi-AZ RDS) is for databases. Option B (AWS Global Accelerator) is for traffic routing. Option C (Two EC2 instances in an Auto Scaling group with EFS) is the correct approach. Option D (Single EC2 with EBS) lacks high availability.

Answer

Deploy ASCS on Amazon RDS Multi-AZ

Answer

Use AWS Global Accelerator with a static IP

Answer

Deploy a single EC2 instance with a large EBS volume

Question 9

A company is migrating an SAP NetWeaver system to AWS. The migration involves moving the application layer to EC2 instances and the database to Amazon RDS for SAP. The company wants to minimize downtime and has a limited time window. Which migration approach should the company use?

Accepted Answer

Use SAP Software Update Manager (SUM) with Database Migration Option (DMO). For minimal downtime, a heterogeneous migration using SAP Software Update Manager (SUM) with DMO (Database Migration Option) is recommended. SUM can handle both the application and database migration in a single process. Option A (AWS DMS) does not support SAP application migration. Option B (SAP SUM with DMO) is correct. Option C (SAP SWPM) is for installation, not migration. Option D (AWS MGN) is for server migration, not SAP-specific.

Answer

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

Answer

Use SAP System Provisioning (SWPM) to export and import the system

Answer

Use AWS Database Migration Service (DMS) for the database and AWS Application Migration Service (MGN) for the application servers

Question 11

A company is migrating its SAP ERP system to AWS and needs to retain the same SAP system ID (SID) and hostnames. The migration must be completed with minimal downtime. Which AWS service or feature supports this requirement?

Accepted Answer

SAP Software Update Manager (SUM) with Database Migration Option (DMO). SAP SID and hostnames are part of the application configuration. AWS does not have a service that directly preserves these; however, using Amazon Route53 private hosted zones can ensure hostname resolution. The migration itself is done using SAP tools. Option A (AWS CloudEndure Migration) now part of MGN. Option B (AWS DMS) is for databases. Option C (SAP Software Update Manager with DMO) can perform the migration while preserving SID and hostnames. Option D (AWS MGN) can preserve hostnames if configured, but for SAP, SUM is the standard tool.

Answer

AWS CloudEndure Migration (now AWS Application Migration Service)

Answer

AWS Application Migration Service (MGN) with custom scripts

Answer

AWS Database Migration Service (DMS)

A company is migrating an SAP system to AWS and needs to ensure that the SAP application servers are highly available. Which TWO actions should the company take? (Choose 2.)

Accepted Answer

Deploy application servers across multiple Availability Zones. For SAP application server HA, deploy across multiple Availability Zones and use an Elastic Load Balancer to distribute traffic. Option A (Place in a single AZ) does not provide HA. Option B (Multiple AZs) is correct. Option C (ELB) is correct. Option D (EFS) is for shared filesystems, not HA for stateless app servers. Option E (Single instance) is not HA.

Answer

Place all application servers in a single Availability Zone

Answer

Use a single large EC2 instance for all application servers

Answer

Use Amazon EFS as the shared /sapmnt filesystem

Question 14

A company is migrating an SAP system from on-premises to AWS. The current system uses a dual-stack (IPv4 and IPv6) network. The company wants to ensure that the SAP system on AWS supports both IP versions. Which THREE actions should the company take? (Choose 3.)

Accepted Answer

Update security group rules to allow both IPv4 and IPv6 traffic. To support dual-stack, assign IPv4 and IPv6 addresses to EC2 instances, configure the VPC for dual-stack, and ensure the security groups allow both IP versions. Option A (Assign both addresses) is correct. Option B (VPC dual-stack) is correct. Option C (Update security groups) is correct. Option D (NAT Gateway) is for outbound IPv4, not required. Option E (Egress-only Internet Gateway) is for IPv6 outbound only, but not mandatory for dual-stack.
