PAS-C01 Migration Practice Test 2 — 15 Questions

Question 1

A company is migrating an on-premises SAP HANA database to AWS. The database is 2 TB in size and has a 4-hour downtime window. Which AWS service should be used to transfer the initial data copy to AWS?

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

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is an offline data transfer device that is physically shipped to the customer, loaded with data, and then returned to AWS. This avoids network bandwidth limitations and is ideal for large initial data copies (2 TB) within a tight 4-hour downtime window. Options B and D (Direct Connect, S3 Transfer Acceleration) rely on network transfer, which may not complete within the downtime. Option C (AWS DataSync) is for online transfers and better suited for smaller or ongoing syncs, not bulk offline transfer.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS DataSync

Answer

AWS Direct Connect

Question 2

A company is migrating its SAP BusinessObjects BI platform to AWS. They plan to use an SAP-certified AMI for the SAP BusinessObjects application server. Which instance type is SAP-certified for SAP BusinessObjects on AWS?

Accepted Answer

r5.xlarge. SAP publishes certified instance types for each SAP application. For SAP BusinessObjects, memory-optimized instances like r5 are certified. Option A (c5.2xlarge) is compute-optimized and not certified for SAP BusinessObjects. Option C (i3.4xlarge) is storage-optimized and not certified. Option D (t3.large) is burstable and not certified.

Answer

c5.2xlarge

Answer

i3.4xlarge

Answer

t3.large

Question 3

A company wants to migrate its SAP application to AWS and needs to ensure high availability for the SAP Central Services (ASCS). Which AWS feature should be used to achieve this?

Accepted Answer

Amazon Route 53 health checks with failover routing. Amazon Route 53 with health checks and failover routing can monitor the health of the primary SAP Central Services (ASCS) instance. If the primary fails, Route 53 automatically routes traffic to a secondary ASCS instance in another Availability Zone, ensuring high availability. Option A (Elastic Load Balancer) is not typically used for ASCS because ASCS requires a single active node and failover, not load distribution. Option B (Auto Scaling groups) is designed for scaling compute capacity horizontally, not for providing high availability for stateful services like ASCS. Option D (Amazon CloudFront) is a content delivery network and is not relevant for SAP ASCS failover.

Answer

Elastic Load Balancer (ELB)

Answer

Auto Scaling groups

Answer

Amazon CloudFront

Question 4

During a migration of an SAP system to AWS, the team discovers that the on-premises storage uses a proprietary deduplication technology. The SAP database will be migrated to Amazon EBS volumes. How should the team address the storage space requirements on AWS?

Accepted Answer

Provision EBS volumes based on the logical size of the database. AWS does not support proprietary deduplication. The team should provision EBS volumes based on the logical size of the database after verifying the actual data size. Option C (using same physical size) is incorrect because deduplication reduces storage. Option A (compression at OS level) may not be effective. Option D (using S3) is not block storage.

Answer

Use OS-level compression on the EBS volumes

Answer

Provision EBS volumes with the same physical size as on-premises

Answer

Use Amazon S3 for database storage

Question 5

A company is migrating its SAP landscape to AWS and plans to use SAP HANA as the database. The HANA system requires high network throughput between application and database servers. Which EC2 placement strategy should be recommended?

Accepted Answer

Cluster placement group. For high network throughput between SAP HANA application and database servers, the recommended placement group is Cluster. Cluster placement groups place instances within the same rack, providing the lowest latency and the highest possible network throughput, which is critical for SAP HANA's in-memory database communication. Option A (No placement group) may result in variable performance. Option B (Partition placement group) is designed for large distributed systems requiring fault isolation across partitions, not for maximizing throughput. Option C (Spread placement group) provides fault isolation but at the cost of lower network throughput compared to Cluster, as instances are placed on distinct hardware and may have higher latency.

Answer

No placement group

Answer

Partition placement group

Answer

Spread placement group

Question 6

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 DMS with the AWS Schema Conversion Tool (SCT) is the correct choice for heterogeneous database migrations, as it handles schema and data type conversion. Option B (AWS Server Migration Service) is used for server-level migrations, not database schema conversion. Option C (AWS Data Pipeline) is for data processing workflows, not schema conversion. Option D (SAP HANA Studio) is an SAP tool for managing HANA databases, not an AWS migration service.

Answer

AWS Server Migration Service

Answer

AWS Data Pipeline

Answer

SAP HANA Studio

Question 7

A company is migrating an SAP landscape to AWS. They have a requirement to retain the same hostnames and IP addresses for the SAP application servers after migration. How can they achieve this?

Accepted Answer

Use VPC endpoints to assign private IPs. To retain hostnames and IP addresses after migration, you can use VPC endpoints to assign private IPs from the VPC subnet to the SAP application servers. Then, configure a private hosted zone in Amazon Route 53 to map the existing hostnames to these static private IPs. This ensures that applications can continue using the same hostnames and IPs. Option A is incorrect because NAT Gateways are used for outbound traffic and do not assign static IPs. Option C is incorrect because Elastic IP addresses are public and do not retain private IPs. Option D is incorrect because AWS Global Accelerator provides anycast IPs for traffic acceleration, not static private IPs for instances.

Answer

Use a NAT Gateway and assign public IPs

Answer

Use Elastic IP addresses and a private hosted zone in Amazon Route 53

Answer

Use AWS Global Accelerator to assign static IP addresses

Question 8

A company is migrating an SAP ERP system to AWS. They have multiple SAP systems (DEV, QAS, PRD) and want to automate the deployment of identical environments. Which AWS service should they use?

Accepted Answer

AWS CloudFormation. AWS CloudFormation enables infrastructure as code, allowing you to define and provision identical AWS resources across multiple environments using templates. For SAP migrations, AWS Launch Wizard can be used to generate CloudFormation templates tailored to SAP requirements. Option A is incorrect because AWS OpsWorks is designed for configuration management with Chef/Puppet, not for SAP system deployment. Option B is incorrect because AWS Elastic Beanstalk is a platform-as-a-service for web applications, not for complex SAP landscapes. Option D is incorrect because AWS CodeDeploy automates application code deployments to existing instances, not full environment provisioning.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Question 9

Refer to the exhibit. An administrator is creating an IAM policy for a user who will perform database migrations using AWS DMS. The migration fails with an error 'Insufficient permissions to create DMS endpoint'. Which missing action should be added to the policy?

Accepted Answer

dms:CreateEndpoint. The policy allows creating replication tasks but not endpoints. To create endpoints, the action 'dms:CreateEndpoint' is required. Option B is wrong because 'dms:ModifyEndpoint' is for modifying existing endpoints. Option C is wrong because 'dms:TestConnection' is for testing connections. Option D is wrong because 'dms:CreateReplicationInstance' is for creating replication instances.

Answer

dms:ModifyEndpoint

Answer

dms:TestConnection

Answer

dms:CreateReplicationInstance

Question 10

A company is migrating a 3 TB SAP ERP system running on Oracle on AIX to SAP HANA on AWS. The system has a complex landscape with multiple application servers and a central Oracle database. The migration must be completed within a 4-day window with minimal downtime. The company has a 1 Gbps AWS Direct Connect connection. The SAP system is heavily customized with many ABAP programs and custom database objects. The migration team plans to use SAP Software Update Manager (SUM) with the Database Migration Option (DMO). During the migration rehearsal, the SUM DMO process fails during the database migration phase with an error indicating that the source database character set is not supported by the target SAP HANA. The source Oracle database uses the WE8ISO8859P1 character set. The team needs to resolve this issue before the final migration. Which course of action should the team take?

Accepted Answer

Convert the source Oracle database character set to UTF-8 (AL32UTF8) before starting the SUM DMO migration.. SAP HANA only supports UTF-8 character encoding. Therefore, the source Oracle database must be converted to UTF-8 (AL32UTF8) before using SUM DMO. Option A is incorrect because SAP HANA Studio migration tools cannot convert an unsupported character set during migration; they also require the source data to be UTF-8. Option B is incorrect because AWS Database Migration Service (AWS DMS) does not support SAP HANA as a target for SAP system migrations and cannot handle the necessary SAP-specific objects and customizations. Option D is incorrect because you cannot modify SAP HANA database parameters to support WE8ISO8859P1; HANA only works with UTF-8.

Answer

Use SAP HANA Studio migration tools to convert the character set during migration without changing the source.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the data and automatically convert the character set.

Answer

Change the target SAP HANA database to use the WE8ISO8859P1 character set by modifying the HANA database parameters.

Question 11

A company is planning to migrate its SAP system from on-premises to AWS. The current system consists of two application servers and one database server running SAP HANA on SUSE Linux. The company wants to use a lift-and-shift migration approach to minimize changes. The migration team has set up an AWS Application Migration Service (AWS MGN) replication environment. The team has completed the test migration and is ready for the final cutover. However, during the final cutover, the team realizes that the source application servers have static IP addresses that are used by other systems for communication. The company cannot change these IP addresses immediately. Which step should the team take to ensure that the AWS instances can use the same IP addresses after migration?

Accepted Answer

Configure the AWS MGN launch template to use the same private IP addresses as the source servers within the target subnet.. AWS MGN allows you to specify the same private IP addresses as the source servers during launch by configuring the launch template to use a specific subnet and optionally a secondary IP address. Option B is incorrect because AWS DMS is used for database replication, not for preserving IP addresses of application servers. Option C is incorrect because Elastic IP addresses are public IPs, not private, and cannot replace the static private IPs required for internal communication. Option D is incorrect because AWS Transit Gateway enables routing between networks but does not preserve the source server's IP addresses; it would still require a separate IP assignment.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the database and keep the source servers running with the same IPs.

Answer

Assign Elastic IP addresses to the source servers and configure the DNS to point to these IPs after migration.

Answer

Set up an AWS Transit Gateway to route traffic between on-premises and AWS with the same IP addresses.

Question 12

A company is moving their SAP Business One application from an on-premises data center to AWS. The application runs on Windows Server and uses Microsoft SQL Server. They want to use Amazon EC2 for the application and Amazon RDS for SQL Server for the database. They have already used AWS SCT to assess the database schema and found that it is compatible. What should they do next to migrate the database with minimal downtime?

Accepted Answer

Use AWS DMS to perform a full load and then enable ongoing replication. AWS DMS can perform a full load and then enable ongoing replication to minimize downtime during migration. Option A is wrong because manual export/import requires downtime. Option B is wrong because the schema is already compatible, so using SCT first is unnecessary; DMS can be used directly. Option D is wrong because copying a backup to S3 and restoring to RDS requires downtime during the restore.

Answer

Export the database to flat files and upload to S3, then import into RDS

Answer

Use AWS SCT to convert the schema and then use AWS DMS

Answer

Take a full backup of the on-premises SQL Server, upload it to Amazon S3, and restore to RDS

Question 13

An organization is migrating their SAP ERP system running on SAP ASE (Sybase) to Amazon RDS for SAP ASE. They have a 5 TB database and a 1 Gbps network. They need to keep the migration window under 6 hours. They plan to use AWS DMS with full load and CDC. During the full load, they notice that the DMS replication instance is using 100% CPU and the full load is progressing slowly. What should they do to meet the migration window?

Accepted Answer

Increase the instance size of the DMS replication instance. Increasing the DMS replication instance size provides more CPU and memory, which directly speeds up the full load process. Option B is incorrect because AWS Snowball is used for offline data transfer and would not help with ongoing replication; it also introduces additional setup and transfer time, making it unsuitable for a <6 hour window. Option C is incorrect because the bottleneck is the DMS replication instance's CPU, not the source database's compute capacity—increasing source resources does not alleviate DMS resource constraints. Option D is incorrect because disabling CDC would cancel ongoing replication, requiring a full reload later, thus increasing downtime beyond the target window.

Answer

Switch to using AWS Snowball for the initial load

Answer

Increase the compute capacity of the source database

Answer

Disable CDC and perform only a full load

Question 14

A company is migrating their SAP CRM system to AWS. They are using AWS DMS to migrate the database from Oracle to Amazon RDS for Oracle. The database size is 1 TB. They have a 1 Gbps network link. They plan to use full load and CDC. During the full load, they notice that the DMS task is running but the progress is very slow. They check CloudWatch metrics and see that the DMS replication instance CPU is at 90% and the write IOPS on the target RDS instance is 5000. The target RDS instance is a db.r5.large (2 vCPU, 16 GB RAM). What should they do to improve the full load performance?

Accepted Answer

Upgrade the target RDS instance to a larger size with higher IOPS. The target RDS instance (db.r5.large) is undersized for the required write throughput, as indicated by the 5000 write IOPS and high DMS replication instance CPU (likely waiting on target writes). Upgrading to a larger instance with higher IOPS (e.g., db.r5.xlarge with provisioned IOPS) will increase write capacity and improve full load performance. Option A is not the best choice because the DMS replication instance is already near 100% CPU, but the bottleneck is likely the target, so increasing the replication instance alone may not help. Option C would reduce overhead but at the cost of losing logging information and is not recommended. Option D is irrelevant as the source is on-premises and not a bottleneck.

Answer

Increase the DMS replication instance size

Answer

Disable the DMS task logging to reduce overhead

Answer

Increase the size of the source Oracle instance

Question 15

A company is migrating a legacy .NET application to AWS. The application uses Windows Authentication and relies on Active Directory for user authentication. The company wants to minimize changes to the application code. Which AWS service should be used to integrate Active Directory with the migrated application?

Accepted Answer

AWS Directory Service for Microsoft Active Directory. AWS Directory Service for Microsoft Active Directory is the correct choice because it provides a fully managed Microsoft Active Directory in the AWS cloud, which natively supports Windows Authentication and Kerberos-based authentication without requiring any code changes. This service allows the migrated .NET application to seamlessly integrate with the existing on-premises Active Directory through a trust relationship or by extending the directory directly into AWS, preserving the application's authentication logic.

Answer

Amazon Cognito

Answer

AD Connector

Answer

Simple AD
