PAS-C01 Migration Practice Test 7 — 15 Questions

Question 1

Which TWO AWS services can be used to monitor the performance of an SAP HANA database on AWS? (Select TWO.)

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch (B) is correct because it collects and tracks SAP HANA performance metrics such as CPU, memory, disk I/O, and custom HANA metrics via the CloudWatch agent or SAP HANA monitoring integration, enabling alarms and dashboards. Amazon RDS Performance Insights (D) is correct because it provides a performance dashboard for database workloads, and although SAP HANA is not natively an RDS engine, Performance Insights can be used with SAP HANA on AWS through supported monitoring configurations to visualize database load and wait events. AWS Trusted Advisor (A) is not a performance monitoring service; it provides best-practice checks and recommendations, not real-time SAP HANA performance data. AWS X-Ray (C) traces application requests and is used for distributed application debugging, not database performance monitoring. AWS Config (E) tracks resource configuration changes and compliance, not performance metrics.

Answer

AWS Trusted Advisor

Answer

AWS X-Ray

Answer

AWS Config

Question 2

A company is migrating its SAP ERP system running on Oracle Database to SAP HANA on AWS. The current on-premises environment has a 5 TB Oracle database with high transaction volume. The migration must be completed within a 4-hour downtime window. The target environment on AWS uses an SAP-certified instance with 1 TB of RAM. The company has a 1 Gbps AWS Direct Connect connection. The migration team is considering using SAP DMO with SUM. However, during a test run, the database export took 6 hours, exceeding the downtime window. What should the migration team do to meet the 4-hour downtime window?

Accepted Answer

Use the SAP HANA Database Migration Option (DMO) with the 'load and move' method. Using the SAP HANA Database Migration Option (DMO) with the 'load and move' method allows the initial data load to be performed during the preparation phase before the downtime window, and only a delta transfer (incremental data) during the actual downtime. This significantly reduces the downtime required compared to the standard DMO method that does the full export and import during downtime. Option A is wrong because performing a system copy to Oracle on AWS first does not directly migrate to SAP HANA and adds unnecessary steps and time. Option C is wrong because upgrading to a larger EC2 instance may improve processing speed but does not address the bottleneck of the 1 Gbps network bandwidth; the export time is limited by network speed. Option D is wrong because AWS Snowball Edge introduces additional time for shipping and data transfer, which would likely exceed the 4-hour window, and it is not optimized for the delta sync required for such a short downtime.

Answer

Perform a system copy to an Oracle database on AWS first, then migrate to HANA

Answer

Upgrade to a larger EC2 instance type with more CPU and memory for the HANA database

Answer

Use AWS Snowball Edge to transfer the initial data and then perform a delta sync

Question 3

A company is migrating an on-premises SAP HANA database to AWS. The database is 2 TB in size, and the network link has a bandwidth of 1 Gbps with an average utilization of 40% during the migration window. They need to minimize the migration time. Which approach should they use?

Accepted Answer

Use AWS Snowball Edge to transfer the data physically.. AWS Snowball Edge is the most efficient approach for large data transfers (2 TB) over a constrained network (1 Gbps at 40% utilization ≈ 400 Mbps). It physically ships the data, avoiding network bottlenecks entirely. Option A is correct. Option B is wrong because requesting a bandwidth increase is impractical and may not be feasible. Option C is wrong: AWS DMS with ongoing replication minimizes downtime for incremental changes, but the initial full load would still be slow over the constrained network, increasing total migration time. Option D is wrong: Amazon S3 Transfer Acceleration only speeds up uploads to S3, not to SAP HANA directly, and it still relies on the network link.

Answer

Request a temporary bandwidth increase from the ISP.

Answer

Use AWS Database Migration Service (DMS) with ongoing replication to minimize downtime.

Answer

Use Amazon S3 Transfer Acceleration to speed up the transfer.

Question 4

During the migration of an SAP ERP system to AWS, the SAP application team reports that after migrating the database to Amazon RDS for SAP HANA, batch jobs that previously ran in 2 hours now take 5 hours. The system uses AWS Direct Connect with adequate bandwidth. Which action is most likely to resolve this performance issue?

Accepted Answer

Increase the RDS instance size and storage IOPS.. The performance degradation is likely due to insufficient compute or IOPS capacity on the RDS instance compared to the original on-premises HANA system. Increasing the instance size (more vCPUs and memory) and storage IOPS directly addresses the bottleneck. Multi-AZ (Option A) provides high availability but does not improve performance. Reducing backup retention (Option C) has no impact on query execution. Since Direct Connect bandwidth is adequate (Option D), increasing it would not help. Therefore, Option B is the most effective action.

Answer

Enable Multi-AZ deployment for RDS.

Answer

Reduce the automated backup retention period.

Answer

Increase the Direct Connect bandwidth.

Question 5

An SAP administrator is migrating an on-premises SAP system to AWS using this IAM policy. When attempting to launch a new EC2 instance from an AMI stored in the S3 bucket, the launch fails. What is the likely cause?

Accepted Answer

The IAM policy does not include ec2:RunInstances.. The launch fails because the IAM policy does not include the ec2:RunInstances permission, which is required to launch new EC2 instances. Option A is incorrect because the ability to stop or start instances is not relevant to launching new instances. Option C is incorrect because the failure is due to the IAM policy, not the S3 bucket policy; the IAM policy may allow s3:GetObject but that does not overcome the lack of ec2:RunInstances. Option D is incorrect because describing instances is not a prerequisite for launching.

Answer

The policy does not allow stopping or starting instances.

Answer

The S3 bucket policy does not allow reading the AMI object.

Answer

The policy does not allow describing EC2 instances.

Question 6

A company is using AWS Database Migration Service (DMS) to migrate an SAP HANA database from on-premises to Amazon RDS for SAP HANA. The migration task fails with the error shown. Which step should the administrator take to resolve this?

Accepted Answer

Modify the DMS task to include character set conversion settings.. DMS migration failures involving character data typically stem from a mismatch between the source and target character sets, and DMS provides task-level settings to handle conversion. Modifying the DMS task to include character set conversion settings allows DMS to translate the source encoding into the target encoding during replication, resolving the error without altering the source or rebuilding the target.

Answer

Change the source database character set to ISO-8859-1.

Answer

Create a new RDS instance with the correct character set.

Answer

Use AWS Server Migration Service (SMS) instead of DMS.

Question 7

A retail company is migrating its SAP ERP system from on-premises to AWS. The system includes an SAP HANA database (2 TB) and an SAP NetWeaver application server. The migration strategy is to use SAP HANA System Replication (HSR) to replicate the database to an EC2 instance running SAP HANA, then perform a takeover. The application server will be migrated using AWS Application Migration Service (MGN). The network connection is AWS Direct Connect with 1 Gbps bandwidth. During a test migration, the HSR replication is working, but the application server replication through MGN is taking much longer than expected. The MGN console shows that the data replication progress is stuck at 45% for several hours. The source server is a physical server with a 500 GB disk, 75% utilized. Which action is most likely to resolve the issue?

Accepted Answer

Increase the disk queue depth on the source server or add additional disks to improve I/O performance.. MGN replication stalls are most commonly caused by the source server's disk I/O subsystem being unable to feed data fast enough to the replication agent, especially on physical servers with older or constrained storage controllers. Increasing disk queue depth or adding spindles/disks improves the source's read throughput, allowing MGN to push blocks to the staging area at a rate that keeps progress moving. The 45% stall for hours with a 500 GB disk at 75% utilization is a classic I/O starvation signature rather than a network or staging capacity issue.

Answer

Convert the source disks to dynamic disks to improve replication speed.

Answer

Increase the staging area size in the MGN replication settings.

Answer

Increase the Direct Connect bandwidth to 10 Gbps.

Question 8

A multinational corporation is migrating its SAP S/4HANA system to AWS. The system consists of a production database (3 TB), a development database (500 GB), and multiple application servers. The migration plan is to use AWS Database Migration Service (DMS) for the databases and AWS Application Migration Service (MGN) for the application servers. The company has set up a test environment in AWS and has performed a test migration. During the test, the production database migration via DMS completed successfully, but the development database migration failed with an error indicating that the source database version is not supported by DMS. The development database is SAP HANA 2.0 SPS 04, while the production database is SAP HANA 2.0 SPS 05. The target for both is Amazon RDS for SAP HANA. The DMS source endpoint was created using the same settings for both databases. Which step should the administrator take to resolve the development database migration failure?

Accepted Answer

Upgrade the source development SAP HANA to a supported version (e.g., SPS 05).. DMS requires a supported SAP HANA version. The development database version (SPS 04) is not supported, so upgrading it to SPS 05 will allow the migration to proceed. Option A is incorrect because SAP HANA System Replication is not designed for migrating to RDS; it replicates between HANA instances. Option C is incorrect because downgrading the production database is unnecessary and risky. Option D is incorrect because AWS SMS is for server migration, not database migration.

Answer

Use SAP HANA System Replication to replicate the development database to RDS.

Answer

Downgrade the production database to match the development version.

Answer

Use AWS Server Migration Service (SMS) for the development database.

Question 9

A healthcare company is migrating its SAP Business Suite system to AWS. The system includes an SAP HANA database (1.5 TB) and an SAP NetWeaver application server. They plan to use SAP HANA System Replication (HSR) for the database and AWS Application Migration Service (MGN) for the application server. The network connection is AWS Direct Connect with 500 Mbps bandwidth. During a test migration, the HSR replication is working, but the MGN replication for the application server is extremely slow. The MGN console shows that the replication is progressing at only 10 Mbps. The source application server is a physical machine with a 300 GB disk, 60% utilized. The administrator has verified that there are no other applications consuming significant network bandwidth. Which action is most likely to improve the MGN replication speed?

Accepted Answer

Increase the bandwidth limit setting in the MGN agent configuration on the source server.. MGN uses a replication server in AWS. The source server may be throttled by the MGN agent's default bandwidth limit. Option A is correct because increasing the agent's bandwidth limit can improve speed. Option B is wrong because changing the staging area disk type on the source does not affect replication speed. Option C is wrong because the network bandwidth is 500 Mbps, higher than 10 Mbps, so network is not the bottleneck. Option D is wrong because changing the target instance type does not affect data transfer.

Answer

Change the target EC2 instance type to a larger size.

Answer

Request an increase in the Direct Connect bandwidth to 1 Gbps.

Answer

Change the staging area disk on the source server from HDD to SSD.

Question 10

A financial services company is migrating its SAP HANA-based system from on-premises to AWS. The system is critical and must have a recovery point objective (RPO) of less than 1 minute and recovery time objective (RTO) of less than 15 minutes. The migration strategy is to use SAP HANA System Replication (HSR) in synchronous mode to an EC2 instance in the same region, then perform a takeover. However, during the test, the HSR replication latency is consistently above 100 ms, which prevents synchronous replication from working. The network between on-premises and AWS uses AWS Direct Connect with 1 Gbps bandwidth, and the physical distance is about 50 miles. Which action should the administrator take to achieve the RPO/RTO requirements?

Accepted Answer

Deploy the target EC2 instance in an AWS Local Zone closer to the on-premises data center.. Synchronous HSR requires low latency (typically under 1 ms round-trip for HANA, and the question states >100 ms prevents it). Deploying the target EC2 instance in an AWS Local Zone closer to the on-premises data center reduces network latency, which can bring it within the threshold for synchronous replication. This addresses the root cause (latency) while preserving the RPO/RTO requirements.

Answer

Use a Site-to-Site VPN instead of Direct Connect.

Answer

Use asynchronous HSR mode instead of synchronous.

Answer

Increase the Direct Connect bandwidth to 10 Gbps.

Question 11

A manufacturing company is migrating its SAP ECC system to AWS. The system includes an SAP HANA database (1 TB) and an SAP NetWeaver application server. They plan to use AWS Database Migration Service (DMS) for the database and AWS Application Migration Service (MGN) for the application server. The network connection is AWS Direct Connect with 1 Gbps bandwidth. During a test migration, the DMS task for the database fails with a connection error. The source database is on an on-premises server that is behind a firewall. The administrator has already opened the necessary ports in the firewall. The DMS replication instance is in a VPC with a public subnet. Which step should the administrator take to resolve the connection issue?

Accepted Answer

Configure the source database to allow connections from the DMS replication instance IP.. The most likely cause of the DMS connection error is that the source database's firewall or security group is not allowing connections from the DMS replication instance's IP address. Even though the administrator opened ports on the on-premises firewall, the database itself may have host-based access controls (e.g., pg_hba.conf for PostgreSQL, or user grants for Oracle) that restrict which IPs can connect. Configuring the source database to allow connections from the DMS replication instance IP directly addresses this.

Answer

Modify the DMS source endpoint to use a different port.

Answer

Create a private subnet for the DMS replication instance and attach a NAT gateway to allow outbound traffic to the on-premises database.

Answer

Open additional ports in the on-premises firewall.

Question 12

A technology company is migrating its SAP Business Warehouse (BW) system to AWS. The system includes an SAP HANA database (2 TB) and multiple application servers. The migration plan is to use SAP HANA System Replication (HSR) for the database and AWS Application Migration Service (MGN) for the application servers. The network connection is AWS Direct Connect with 1 Gbps bandwidth. During a test migration, the HSR replication is working, but the MGN replication for one of the application servers is failing with an error: "The agent cannot communicate with the MGN service endpoint." The source server is a Windows Server 2016 machine. The administrator has verified that the source server has internet connectivity. Which action is most likely to resolve the issue?

Accepted Answer

Configure an HTTP proxy on the source server to route traffic through the corporate proxy.. The MGN agent error 'cannot communicate with the MGN service endpoint' on a source server that has internet connectivity strongly suggests outbound traffic is being forced through a corporate HTTP proxy that the agent is not configured to use. Configuring the MGN agent to route through the corporate proxy (via the agent's proxy settings) allows it to reach the MGN service endpoint. This is the most likely fix given the environment.

Answer

Reinstall the MGN agent on the source server.

Answer

Create a VPC endpoint for AWS Application Migration Service in the source VPC.

Answer

Change the source server's OS to Linux.

Question 13

A retail company is migrating its SAP ERP system to AWS. The system includes an SAP HANA database (1 TB) and an SAP NetWeaver application server. The migration strategy is to use AWS Database Migration Service (DMS) for the database and then manually install the application server on an EC2 instance. The network connection is AWS Direct Connect with 1 Gbps bandwidth. During the migration, the DMS task for the database completes successfully, but the application server installation fails because the SAP installation media is not accessible. The installation media is stored on an on-premises file server. The EC2 instance for the application server is in a private subnet with no direct internet access. The administrator has created a VPC endpoint for S3 to access the media, but the media is not in S3. Which step should the administrator take to make the installation media available?

Accepted Answer

Add a route in the VPC route table to direct traffic to the on-premises network via Direct Connect.. The EC2 instance is in a private subnet with no internet access, and the installation media is on an on-premises file server. Since Direct Connect is already in place, the administrator should add a route in the VPC route table to direct traffic to the on-premises network via the Direct Connect virtual interface. This allows the EC2 instance to access the media over the private connection.

Answer

Copy the installation media to an S3 bucket and use the VPC endpoint to access it.

Answer

Attach an internet gateway to the VPC and assign a public IP to the EC2 instance.

Answer

Use AWS Storage Gateway to cache the media in S3.

Question 14

A company is migrating a critical Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a high transaction rate. The migration must have minimal downtime. Which TWO AWS services or features should be used to achieve this? (Choose two.)

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication. Option B is correct because AWS Database Migration Service (DMS) with ongoing replication (change data capture) continuously applies changes from the source Oracle database to the RDS for Oracle target, allowing the cutover to happen with minimal downtime even for a 2 TB, high-transaction-rate database. Option E is correct because the AWS Schema Conversion Tool (SCT) converts the source Oracle schema and PL/SQL objects into a format compatible with the RDS for Oracle target, which is a necessary step before or alongside the DMS data migration. Option A is not appropriate because AWS DataSync is a file/object transfer service, not a database replication tool. Option C is not appropriate because AWS Snowball is a physical data-transfer appliance for bulk offline migration and cannot provide minimal-downtime ongoing replication. Option D is not appropriate because AWS Server Migration Service migrates on-premises servers/VMs to AWS, not Oracle databases into RDS.

Answer

AWS DataSync

Answer

AWS Snowball

Answer

AWS Server Migration Service (SMS)

Question 15

Refer to the exhibit. A company is migrating its data to Amazon S3. The security team has provided this IAM policy for the migration user. However, the migration fails with an Access Denied error when trying to upload files to the bucket. What is the most likely cause?

Accepted Answer

The bucket policy explicitly denies the s3:PutObject action for the IAM user.. The IAM policy allows s3:PutObject on the specified bucket. However, if the bucket has an explicit deny statement in its bucket policy that denies s3:PutObject for the user or any principal, that deny will override the IAM policy allow. Since the migration fails with Access Denied, the most likely cause is that the bucket policy explicitly denies the s3:PutObject action for the IAM user. Therefore, Option A is correct. Options B, C, and D are incorrect: Option B is wrong because the IAM policy does include s3:PutObject; Option C is wrong because there is no encryption requirement in the policy; Option D is wrong because default encryption does not cause Access Denied if the user lacks permission to use the key, but the policy does not mention KMS permissions.

Answer

The IAM policy does not include s3:PutObject permission.

Answer

The IAM policy does not include kms:Decrypt permission.

Answer

The bucket has default encryption enabled and the IAM user does not have permission to use the encryption key.
