PAS-C01 Migration Practice Test 24 — 15 Questions

Question 1

A company is migrating its SAP system from on-premises to AWS. The system uses a shared filesystem (NFS) for transport directories and logs. The company wants to use AWS storage services to provide a similar shared filesystem. Which storage solution is MOST appropriate for this migration?

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

Accepted Answer

Amazon EFS (Elastic File System). Amazon EFS provides a managed NFS filesystem that can be mounted by multiple EC2 instances, making it suitable for SAP transport directories that require shared POSIX/NFS access. Option B (Amazon S3 with a mount point via s3fs-fuse) is not ideal because S3 is object storage and s3fs-fuse does not provide full POSIX compliance or consistent NFS semantics, leading to performance and concurrency issues. Option C (Amazon FSx for Windows File Server) uses SMB protocol, not NFS, so it is not appropriate for SAP systems that expect NFS. Option D (Amazon EBS with multi-attach enabled) allows attaching a single volume to multiple instances but is limited to a few instances, requires a cluster-aware filesystem, and is more complex to manage than EFS for shared filesystem use cases.

Answer

Amazon S3 with a mount point via s3fs-fuse

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with multi-attach enabled

Question 2

A company is migrating an SAP environment to AWS and wants to automate the provisioning of infrastructure using code. Which AWS service should be used for this purpose?

Accepted Answer

AWS CloudFormation. AWS CloudFormation enables infrastructure as code (IaC) to provision and manage AWS resources in a repeatable and automated manner, which is ideal for automating SAP environment provisioning. Option A (AWS Elastic Beanstalk) is incorrect because it is a platform-as-a-service (PaaS) for deploying and scaling web applications, not for provisioning general infrastructure. Option B (AWS CloudFormation) is correct because it directly provides infrastructure as code. Option C (AWS CodeDeploy) is incorrect because it automates application deployments to compute services, not infrastructure provisioning. Option D (AWS OpsWorks) is incorrect because it is a configuration management service using Chef/Puppet, not a direct infrastructure provisioning service like CloudFormation.

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Answer

AWS OpsWorks

Question 3

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. The correct answers are A and B. Compatibility of SAP HANA versions (A) is critical because the backup can only be restored to a target system running a compatible HANA version. Network bandwidth (B) directly affects the time required to transfer the backup files, which is especially important for large databases. Option C is incorrect because SAP HANA on AWS is typically deployed on EC2 instances, not Amazon RDS; there is no Amazon RDS for SAP HANA. Option D is incorrect because encryption settings for EBS volumes are not a critical consideration during backup and restore; encryption can be applied at rest but does not prevent the restore process. Option E is incorrect because network latency is not a major factor for offline backup transfer; it is more relevant for real-time replication.

Answer

Amazon RDS for SAP HANA instance class

Answer

Encryption settings for Amazon EBS volumes

Answer

Network latency between on-premises and AWS

Question 4

Which THREE factors are essential when planning the migration of an SAP system with near-zero downtime requirements? (Choose three.)

Accepted Answer

Network bandwidth between source and target. For near-zero downtime migration, network bandwidth (A) determines the speed of initial and delta data transfer, directly impacting the cutover window. Data volume and change rate (B) affect the feasibility of completing delta syncs within the allowed downtime. The ability to perform a final delta sync (D) is crucial to minimize the final cutover window by synchronizing only changes since the last sync. Performance testing strategy (C) can be done post-migration and does not directly affect downtime planning. Storage type choice (E) impacts performance but not the downtime itself, as long as sufficient throughput is available.

Answer

Performance testing strategy for the target system

Answer

Choice of storage type (EBS vs. EFS)

Question 5

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. Lift-and-shift (rehost) using AWS Application Migration Service and the 7-Migration Strategies (7Rs) rehost approach minimize re-architecture. Option A is wrong because replatforming involves some changes. Option D is wrong because refactoring involves significant re-architecture. Option E is wrong because AWS DMS is for databases, not full systems.

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 6

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 includes dms:CreateReplicationTask and permissions for S3 and RDS, but it lacks dms:CreateEndpoint, which is required to create source and target endpoints for DMS migrations. Without this permission, the migration user cannot set up the endpoints necessary for the replication process.

- Option A (dms:TestConnection): This permission is used to test endpoint connectivity, but it is not essential for creating a replication task; the missing permission is for creating endpoints.
- Option B (s3:ListBucket): While s3:ListBucket might be useful for browsing S3 objects, it is not strictly required because DMS can access objects by key if the path is provided.
- Option C (rds:ModifyDBInstance): This permission is not needed for DMS to perform migration; DMS uses the RDS instance as a target but does not require modification rights.
- Option D (dms:CreateEndpoint): Correct. Without this permission, the user cannot create the source or target endpoints, which are prerequisites for running a DMS task.

Answer

dms:TestConnection

Answer

s3:ListBucket

Answer

rds:ModifyDBInstance

Question 7

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 error occurs because the source DB2 database's tablespace using automatic storage exceeds the target SAP HANA's disk capacity of 2 TB. The SUM DMO tool requires enough space to store the migrated data during the conversion process. Increasing the disk storage of the SAP HANA instance to at least 2.5 TB (or larger to accommodate the full 2 TB source plus overhead) resolves the space issue and allows the migration to proceed. Option A is incorrect because AWS DMS does not support SAP HANA as a target for direct migration. Option C is incorrect because DB2 compression reduces storage but does not address the automatic storage tablespace size limitation that causes the SUM error. Option D is incorrect because splitting the migration into DMS and SUM phases is not supported for DB2 to HANA; SUM DMO is the recommended tool for this combined migration and upgrade.

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 8

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service or feature should they use?

Accepted Answer

AWS Database Migration Service (AWS DMS) with ongoing replication. (AWS DMS with ongoing replication) is correct because it supports a full load followed by continuous change data capture (CDC) replication, enabling minimal downtime and data consistency during migration from on-premises Oracle to Amazon RDS for Oracle. Option B (RDS Read Replica) is wrong because it is used for scaling read traffic, not for migrating data. Option C (VPC Peering) is a networking feature that connects VPCs but does not perform data migration. Option D (AWS SCT) is wrong because it only converts database schemas and code, not the actual data.

Answer

RDS Read Replica

Answer

VPC Peering

Answer

AWS Schema Conversion Tool (AWS SCT)

Question 9

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 provides a high-capacity physical device for offline data transfer, avoiding network bandwidth limitations. Option A is wrong because AWS Direct Connect requires setup time and still is limited by 1 Gbps bandwidth, which would still result in long transfer times for 10 TB. Option C is wrong because AWS SCT is for schema conversion, not data transfer. Option D is wrong because AWS DMS over a 1 Gbps link would take too long for 10 TB of data.

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 10

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 11

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. The correct answers are C, D, and E. Option C is correct because you must verify that your SAP licenses are eligible for migration to AWS under the BYOL model. Option D is correct because using Dedicated Hosts or Dedicated Instances is required to meet SAP licensing requirements for BYOL. Option E is correct because SAP software must be deployed on instances that support 'software license mobility' to comply with the BYOL model. Option A is incorrect because SAP BYOL does not allow unrestricted migration of licenses; you must adhere to specific licensing terms. Option B is incorrect because AWS License Manager is an optional tool for license tracking, not a mandatory step for BYOL compliance.

Answer

Migrate existing SAP licenses to AWS without any restrictions

Answer

Use AWS License Manager to track and manage licenses

Question 12

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). Options D and E are correct. AWS Storage Gateway (file gateway) provides a file interface to Amazon S3, allowing SAP systems to write archive files to file shares that are backed by S3, thus integrating SAP archiving with S3. SAP Data Archiving with S3 as the archive store is a native SAP solution that directly uses S3 as a target for archiving objects. Option A is incorrect because Amazon S3 Batch Operations performs bulk actions on existing S3 objects, not for archiving from SAP. Option B is incorrect because Amazon S3 Glacier is a storage class, not a service for integration; it can be used as a destination within S3 lifecycle policies but is not directly integrated with SAP. Option C is incorrect because Amazon CloudFront is a content delivery network (CDN) and is not designed for SAP archiving.

Answer

Amazon S3 Batch Operations

Answer

Amazon S3 Glacier

Answer

Amazon CloudFront

Question 13

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' indicates the IAM policy lacks necessary permissions for the DMS task. The missing actions are dms:CreateEndpoint and dms:DescribeEndpoints, which are required to create and describe endpoints during the migration. Option B is correct because the policy explicitly denies these actions (or does not include them). Option A is incorrect because the policy does not allow all DMS actions; it is missing these two. Option C is incorrect because the error is not related to dms:CreateReplicationTask. Option D is incorrect because using a wildcard for Resource is not the cause; the issue is the missing actions, not the resource scope.

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

Question 14

Refer to the exhibit. An administrator runs the CLI command to check the status of SAP application instances. The output shows two instances. The administrator needs to stop the running instance and start the stopped instance for a planned migration. Which command should they run?

Accepted Answer

aws ec2 start-instances --instance-ids i-0abcd1234efgh5678 && aws ec2 stop-instances --instance-ids i-0dcba4321hgfe8765. They need to start i-0abcd1234efgh5678 (stopped) and then stop i-0dcba4321hgfe8765 (running). Option A is wrong because the order is reversed. Option C is wrong because they start the wrong instance. Option D is wrong because they stop the wrong instance.

Answer

aws ec2 start-instances --instance-ids i-0dcba4321hgfe8765 && aws ec2 stop-instances --instance-ids i-0abcd1234efgh5678

Answer

aws ec2 start-instances --instance-ids i-0abcd1234efgh5678 && aws ec2 stop-instances --instance-ids i-0abcd1234efgh5678

Answer

aws ec2 stop-instances --instance-ids i-0dcba4321hgfe8765 && aws ec2 start-instances --instance-ids i-0dcba4321hgfe8765

Question 15

A company is migrating their SAP ERP system running on an on-premises IBM Db2 database to Amazon RDS for Db2. The migration must have minimal downtime. The current database size is 2 TB. The network link between on-premises and AWS is 1 Gbps. The migration team plans to use AWS DMS with a full load followed by ongoing replication. During a test migration, they notice that the full load takes longer than expected, causing the change data capture (CDC) lag to grow. They need to adjust the migration approach to meet the downtime window. What should they do?

Accepted Answer

Increase the compute capacity of the DMS replication instance. Increasing the compute capacity of the DMS replication instance provides more processing power to handle the full load faster, reducing the time taken and preventing CDC lag from growing. Option A is incorrect because using multiple DMS tasks in parallel can cause conflicts and may not improve performance due to constraints on the source database. Option C is incorrect because an RDS read replica cannot offload the initial load from an on-premises source. Option D is incorrect because using Snowball for offline transfer would interrupt ongoing replication and is not suitable for minimal downtime.

Answer

Use multiple DMS tasks in parallel for the full load

Answer

Create an RDS read replica to offload the initial load

Answer

Use AWS Snowball to transfer the initial load and then resume CDC
