PAS-C01 Migration Practice Test 24 — 15 Questions

Question 1

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. DMS needs the dms:CreateEndpoint permission to create source and target endpoints. The policy includes dms:CreateReplicationTask but not dms:CreateEndpoint. Option A is wrong because s3:ListBucket is not strictly required if the user knows the object keys. Option B is wrong because rds:ModifyDBInstance is not needed. Option D is wrong because dms:TestConnection is for testing but not required for creating tasks.

Answer

dms:TestConnection

Answer

s3:ListBucket

Answer

rds:ModifyDBInstance

Question 2

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 supports only UTF-8. Therefore, the source database must be converted to UTF-8 before migration. Option A is wrong because SAP HANA does not support WE8ISO8859P1 directly. Option B is wrong because HANA Studio migration tools also require UTF-8. Option D is wrong because AWS DMS does not support SAP HANA as a target for character set conversion.

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 3

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 source database is larger than the target HANA disk storage. The team needs to increase the HANA disk size to accommodate the migration. Option B is wrong because splitting the migration into chunks is complex and not standard. Option C is wrong because DB2 compression may not help if the issue is tablespace size. Option D is wrong because AWS DMS does not support HANA.

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 4

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 launching instances with the same private IP addresses by choosing the appropriate subnet and optionally using a secondary IP address. Option A is wrong because AWS Transit Gateway does not provide IP address preservation. Option B is wrong because Elastic IP addresses are public IPs, not private. Option D is wrong because AWS DMS is for databases, not 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 5

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. Option D is correct because AWS DMS with ongoing replication enables minimal downtime migration by continuously replicating changes after the initial load. Option A is wrong because AWS SCT only converts schemas, not data. Option B is wrong because VPC Peering is a network feature. Option C is wrong because a Read Replica is for read scaling, not migration.

Answer

RDS Read Replica

Answer

VPC Peering

Answer

AWS Schema Conversion Tool (AWS SCT)

Question 6

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

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 7

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

Accepted Answer

AWS Elastic Disaster Recovery (DRS). Options B and D are correct. AWS Elastic Disaster Recovery (DRS) enables replication for failover, and Amazon EFS provides shared storage for SAP HANA. Option A is wrong because S3 is not suitable for database storage. Option C is wrong because DynamoDB is NoSQL, not for SAP HANA. Option E is wrong because Redshift is a data warehouse.

Answer

Amazon Redshift

Answer

Amazon DynamoDB

Answer

Amazon S3

Question 8

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. Options A, C, and E are correct. A is correct because BYOL requires using dedicated hosts or instances that support license mobility. C is correct because SAP software must be deployed on instances that allow dedicated usage. E is correct because license verification is needed for audit. Option B is wrong because using AWS License Manager is optional, not mandatory. Option D is wrong because BYOL is typically used for new instances, not existing ones.

Answer

Migrate existing SAP licenses to AWS without any restrictions

Answer

Use AWS License Manager to track and manage licenses

Question 9

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 A and D are correct. AWS Storage Gateway provides a file interface to S3, and SAP Data Archiving can use S3 as a target. Option B is wrong because Glacier is a storage class, not a service. Option C is wrong because CloudFront is a CDN. Option E is wrong because S3 Batch Operations is for bulk actions, not archiving.

Answer

Amazon S3 Batch Operations

Answer

Amazon S3 Glacier

Answer

Amazon CloudFront

Question 10

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. Option D is correct because the DMS task requires permissions for dms:CreateEndpoint and dms:DescribeEndpoints, which are missing from the policy. Option A is wrong because the policy does allow DMS actions. Option B is wrong because the policy allows all DMS actions listed. Option C is wrong because the policy does not restrict resources.

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 11

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. Option B is correct because 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 12

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. Option A is correct because using a larger instance for the DMS replication instance increases throughput for the full load, reducing the time and preventing CDC lag growth. Option B is wrong because the database is on-premises, not RDS. Option C is wrong because CDC is already in use; parallel tasks would complicate and may not help. Option D is wrong because Snowball is for offline transfer, which would not allow ongoing replication.

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

Question 13

A company is migrating their SAP HANA database to AWS. The on-premises HANA system is 10 TB and runs on a physical server. They need to minimize the migration time and cannot afford more than 4 hours of downtime. The network bandwidth is limited to 500 Mbps. They decide to use AWS Snowball Edge to transfer the data. After copying the data to Snowball, they ship it to AWS. However, upon receiving the data, they find that the checksum verification fails. What should they do to resolve this issue and complete the migration within the downtime window?

Accepted Answer

Contact AWS Support to perform a remote data verification and import. Option D is correct because AWS Support can perform a remote data verification and re-import if needed, potentially avoiding a reship. Option A is wrong because re-copying and reshipping would exceed the downtime window. Option B is wrong because DMS over 500 Mbps would take too long. Option C is wrong because Direct Connect setup takes weeks.

Answer

Re-copy the data to a new Snowball and reship

Answer

Use AWS DMS over the existing network to transfer the data incrementally

Answer

Order an AWS Direct Connect connection to increase bandwidth

Question 14

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. Option B is correct because AWS DMS can perform a full load and then continuously replicate changes to minimize downtime. Option A is wrong because copying the backup to S3 and restoring to RDS would require downtime during the restore. Option C is wrong because they already assessed compatibility with SCT. Option D is wrong because manual export/import requires downtime.

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 15

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. Option A is correct because using a larger DMS replication instance provides more CPU and memory, speeding up the full load. Option B is wrong because they are already using CDC; changing to full load only would cause more downtime. Option C is wrong because increasing source database resources may not help due to network and DMS capacity. Option D is wrong because Snowball is for offline transfer, not for ongoing replication.

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
