PAS-C01 Migration Practice Test 13 — 15 Questions

Question 1

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?

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

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 (change data capture) performs a full load and then continuously applies changes from the source Oracle database to the RDS target, keeping the target in sync until cutover. This minimizes downtime because the cutover window is reduced to the brief period needed to stop writes on the source and let DMS drain the remaining changes, rather than a full 2 TB transfer during the migration window.

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 2

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.. SUM with Database Migration Option (DMO) is the SAP-recommended one-step approach that combines the system upgrade/conversion with the database migration to SAP HANA, which is essential for moving from ECC on DB2 to S/4HANA on HANA within a tight 48-hour window. DMO handles the data transfer and conversion in a single downtime-optimized run, minimizing cutover time. It also supports the stored procedures and triggers through the SAP-controlled migration path rather than raw database replication.

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 3

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 (DRS) is the most cost-effective option because it uses lightweight replication agents and low-cost staging area resources (small EC2 instances and EBS volumes) rather than full production-sized infrastructure. Test instances are launched only when needed in a sandbox VPC, and you pay for them only during the test window. This matches the goal of validating the migration process without duplicating production costs.

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 4

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.. For a 6 TB SAP HANA system with a 10 Gbps Direct Connect link, the backup-and-restore method is the most practical because it leverages the existing high-bandwidth dedicated connection to transfer backup files to Amazon S3, then restores to SAP HANA on AWS. This approach is well-documented in AWS SAP migration guidance and avoids the complexity of maintaining dual production systems during replication.

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 5

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.

Question 6

Which TWO considerations are critical when migrating an SAP HANA database to AWS using backup and restore? (Choose two.)

Accepted Answer

Compatibility of SAP HANA version between source and target. Option A is correct because SAP HANA backup and restore requires that the target system run a compatible SAP HANA version (same or newer revision) so that the backup created on the source can be recovered on the target; version mismatches can make the backup unusable. Option B is correct because moving the backup files to AWS (for example to Amazon S3 or Amazon EFS) is a data-transfer-intensive operation, so available network bandwidth directly determines migration duration and feasibility. Option C is not relevant because SAP HANA is not offered as an Amazon RDS engine, so there is no RDS for SAP HANA instance class to consider. Option D is not a critical migration consideration for backup and restore, since EBS encryption is a security configuration applied independently and does not affect the backup/restore compatibility or transfer. Option E is not correct because while latency can affect transfer efficiency, bandwidth is the decisive factor for bulk backup data movement, and latency is not one of the two critical considerations for this scenario.

Answer

Amazon RDS for SAP HANA instance class

Answer

Encryption settings for Amazon EBS volumes

Answer

Network latency between on-premises and AWS

Question 7

Which TWO methods can be used to migrate an SAP system from on-premises to AWS while minimizing the need for re-architecture? (Choose two.)

Accepted Answer

Rehost by manually copying servers to Amazon EC2. Option B is correct because a manual rehost (lift-and-shift) copies the existing SAP servers, OS, and configuration onto Amazon EC2 instances, preserving the current architecture and avoiding re-architecture. Option C is correct because AWS Application Migration Service (AWS MGN) performs an automated block-level replication of on-premises servers into EC2, which is the canonical rehost method that minimizes changes to the SAP system. Option A is not correct because moving to Amazon RDS for SAP is a replatform that changes the database layer and requires re-architecture and validation. Option D is not correct because refactoring to microservices is a fundamental re-architecture, the opposite of what the scenario asks. Option E is not correct because migrating to Amazon Aurora with AWS DMS is a replatform/database change, not a minimal-change migration.

Answer

Replatform by moving to Amazon RDS for SAP

Answer

Refactor the application to use microservices

Answer

Use AWS Database Migration Service to move the database to Amazon Aurora

Question 8

Refer to the exhibit. An SAP administrator is creating an IAM policy for a migration user who will use AWS DMS to migrate an SAP database to Amazon RDS. The migration also requires reading from an S3 bucket containing source database export files and writing the DMS logs to another S3 bucket. The policy above is attached. Which required permission is MISSING from this policy?

Accepted Answer

dms:CreateEndpoint. The policy is missing dms:CreateEndpoint, which is required for AWS DMS to create source and target endpoints for the SAP database and Amazon RDS. Without this permission, the migration user cannot define the endpoints needed to start the replication task. The other permissions listed (e.g., dms:StartReplicationTask, s3:GetObject, s3:PutObject) are present but insufficient without endpoint creation.

Answer

dms:TestConnection

Answer

s3:ListBucket

Answer

rds:ModifyDBInstance

Question 9

A company is migrating its SAP Business Warehouse (BW) system from on-premises to AWS. The system uses IBM DB2 as the database and is 2 TB in size. The company wants to use the SAP BW/4HANA version on AWS. The migration must be completed within a 72-hour window. The company has a 1 Gbps AWS Direct Connect connection. The migration team decides to use the SAP Software Update Manager (SUM) with the Database Migration Option (DMO) to migrate and upgrade to BW/4HANA. During the migration, they encounter an error that the source DB2 database has a tablespace that uses automatic storage and is larger than 2 TB. The SUM DMO tool stops with an error indicating insufficient space in the target SAP HANA database. The target SAP HANA system is provisioned with 1 TB of memory and 2 TB of disk storage. The team needs to proceed with the migration. Which action should the team take to resolve this issue?

Accepted Answer

Increase the disk storage of the SAP HANA instance to at least 2.5 TB to accommodate the migrated data.. The SUM DMO error indicates the target SAP HANA database lacks sufficient space to hold the migrated DB2 data, which exceeds 2 TB. Since the HANA instance has only 2 TB of disk storage, increasing disk storage to at least 2.5 TB provides the headroom needed for the migration and subsequent operations. This directly addresses the 'insufficient space' error without changing the migration methodology.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the data directly to SAP HANA, bypassing SUM DMO.

Answer

Compress the DB2 database on the source side to reduce its size before migration.

Answer

Split the migration into two phases: migrate the data using AWS DMS first, then use SUM for the upgrade.

Question 10

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.. The correct option is A: configuring the AWS MGN launch template to use the same private IP addresses as the source servers within the target subnet. AWS Application Migration Service allows you to specify static private IP addresses in the launch template, so the migrated EC2 instances retain the exact IPs the source application servers used, satisfying the requirement that dependent systems continue to reach them without changes. This works as long as the target subnet's CIDR range matches the source network and those IPs are free. Option B is wrong because AWS DMS is for database replication, not for preserving application server IPs, and it doesn't address the cutover of the application servers. Option C is wrong because Elastic IP addresses are public IPv4 addresses, not the private static IPs used for internal communication, and assigning them to source servers doesn't make the AWS instances use the same private IPs. Option D is wrong because a Transit Gateway routes traffic between networks but does not let AWS instances assume the source servers' private IP addresses.

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 11

A company is migrating a 10 TB SAP HANA database to AWS. They have a limited time window and need to minimize migration time. The database is running on a physical server with 1 Gbps network link to AWS. Which migration strategy is MOST suitable?

Accepted Answer

Use AWS Snowball Edge to transfer the database files offline. AWS Snowball Edge is designed for large-scale offline data transfers, typically when network bandwidth is limited or time constraints are tight. For a 10 TB database over a 1 Gbps link, the transfer would take over 22 hours at full utilization, but real-world throughput is often lower. Snowball Edge can transfer the data physically, often within a day or two, significantly reducing migration time. This makes it the most suitable strategy for minimizing migration time.

Answer

Use AWS Direct Connect to increase bandwidth before migration

Answer

Use AWS SCT to convert the database and then use DMS

Answer

Use AWS DMS over the existing network link

Question 12

A company is migrating an SAP ERP system to AWS. Which AWS service should they use to set up a highly available SAP HANA database?

Accepted Answer

Amazon EFS. Only Amazon EFS is correct for setting up a highly available SAP HANA database. Amazon EFS provides the shared storage (e.g., for /hana/shared) required for SAP HANA multi-node or scale-out configurations, which support high availability. AWS Elastic Disaster Recovery (DRS) is a disaster recovery service that enables replication and recovery to a different region or account, but it does not provide automatic failover for high availability within a single region. Amazon Redshift is a data warehouse and cannot host SAP HANA. Amazon DynamoDB is a NoSQL database and cannot run SAP HANA. Amazon S3 is object storage, not designed for the low-latency, high-throughput requirements of SAP HANA.

Answer

AWS Elastic Disaster Recovery (DRS)

Answer

Amazon Redshift

Answer

Amazon DynamoDB

Answer

Amazon S3

Question 13

An organization is migrating a critical SAP workload to AWS. They need to ensure compliance with SAP's 'Bring Your Own License' (BYOL) model. Which THREE steps should they take?

Accepted Answer

Verify that the SAP licenses are eligible for migration to AWS. Option C is correct because SAP BYOL requires confirming that the specific SAP license entitlement permits running the workload on AWS cloud infrastructure before migration. Option D is correct because SAP licensing commonly requires dedicated tenancy (Dedicated Hosts or Dedicated Instances) so the customer's own licenses can be applied to physical sockets/cores rather than shared multi-tenant hardware. Option E is correct because the chosen EC2 instances must support software license mobility, meaning the licensing terms allow the licensed software to be moved to AWS-hosted instances. Option A is incorrect because SAP licenses cannot simply be migrated without restrictions; eligibility, tenancy, and licensing terms must be validated. Option B is incorrect because AWS License Manager is a useful tracking tool but is not a required step to satisfy SAP BYOL compliance.

Answer

Migrate existing SAP licenses to AWS without any restrictions

Answer

Use AWS License Manager to track and manage licenses

Question 14

A company is migrating an SAP Business Suite system to AWS. They want to reduce storage costs by using Amazon S3 for archiving. Which TWO AWS services can be used to integrate SAP with Amazon S3 for archiving?

Accepted Answer

AWS Storage Gateway (file gateway). Option D, AWS Storage Gateway (file gateway), is correct because it presents an SMB/NFS file interface backed by Amazon S3, allowing the SAP application to write archive files to a local mount point while the data is durably stored in S3, which is a documented integration pattern for SAP archiving. Option E, SAP Data Archiving with S3 as the archive store, is correct because SAP's archiving tools (SAP ArchiveLink/Content Repository, or the SAP-certified connector for AWS) can be configured to write archive files directly to an S3 bucket as the content repository, eliminating local storage. Option A, Amazon S3 Batch Operations, is not an SAP integration service; it is used to perform bulk actions on existing S3 objects and does not provide an archive interface for SAP. Option B, Amazon S3 Glacier, is a storage class/archive service rather than an integration mechanism for SAP, and Option C, Amazon CloudFront, is a content delivery network that has no role in SAP archiving to S3.

Answer

Amazon S3 Batch Operations

Answer

Amazon S3 Glacier

Answer

Amazon CloudFront

Question 15

Refer to the exhibit. An administrator is setting up an AWS DMS task to migrate an SAP database. They receive an error that they are not authorized to perform the operation. Which statement is true about the IAM policy?

Accepted Answer

The policy is missing the dms:CreateEndpoint and dms:DescribeEndpoints actions. The error 'not authorized to perform the operation' during DMS setup typically occurs when the IAM policy attached to the user/role lacks the specific DMS API actions required for the step being performed. Creating an endpoint and describing endpoints are foundational DMS actions needed before a replication task can be created, so their absence is the most plausible cause of the authorization failure. The correct answer identifies the missing dms:CreateEndpoint and dms:DescribeEndpoints permissions.

Answer

The policy allows all DMS actions

Answer

The policy is missing the dms:CreateReplicationTask action

Answer

The policy should specify an ARN instead of a wildcard for Resource
