PAS-C01 Migration Practice Test 22 — 15 Questions

Question 1

A company is migrating an SAP Business Suite system to AWS. The source database is Oracle. The target is Amazon RDS for Oracle. Which AWS service should be used to automate the schema conversion and data migration?

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

Accepted Answer

Both AWS SCT and AWS DMS. Schema conversion is handled by AWS Schema Conversion Tool (SCT) and data migration with minimal downtime is handled by AWS Database Migration Service (DMS). Option A is wrong because SCT alone does not migrate data. Option C is wrong because AWS Application Discovery Service is used for discovery, not migration. Option D is wrong because DMS alone does not convert schemas.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Application Discovery Service

Answer

AWS Database Migration Service (DMS)

Question 2

A company is migrating a large SAP landscape to AWS. The migration plan includes using AWS CloudEndure Migration for the application servers. However, the SAP database requires a different approach. Which database migration method is recommended for an SAP HANA database?

Accepted Answer

Use SAP HANA System Replication (HSR).. The recommended method for migrating an SAP HANA database is SAP HANA System Replication (HSR). HSR provides a database-aware, block-level replication with near-zero downtime, making it ideal for SAP HANA migrations. Option A is incorrect because AWS Schema Conversion Tool (SCT) is used for converting schemas between different database engines (e.g., Oracle to Amazon RDS), not for HANA-to-HANA migration. Option B is incorrect because AWS CloudEndure Migration performs host-level replication and lacks database consistency features required for SAP HANA. Option C is incorrect because AWS DMS does not support SAP HANA as a target database; it is used for heterogeneous migrations to AWS database services.

Answer

Use AWS Schema Conversion Tool (SCT) to convert the HANA schema.

Answer

Use AWS CloudEndure Migration for both application and database servers.

Answer

Use AWS DMS with Oracle as a source and HANA as target.

Question 3

A company is migrating an SAP system to AWS and needs to ensure that the target EC2 instances have the correct SAP kernel parameters. Which AWS service can be used to automate the configuration of these parameters?

Accepted Answer

AWS Systems Manager State Manager. AWS Systems Manager State Manager is correct because it allows you to define and enforce a configuration policy for EC2 instances, including SAP kernel parameters. Option A (EC2 User Data) runs only once at launch and cannot enforce ongoing changes. Option B (AWS OpsWorks) is a configuration management service but is not the best fit for this specific task. Option C (AWS CloudFormation) is designed for infrastructure provisioning, not for in-guest OS configuration.

Answer

EC2 User Data scripts

Answer

AWS OpsWorks

Answer

AWS CloudFormation

Question 4

An IAM policy for a migration team is shown in the exhibit. The team is unable to start a DMS replication task. What is the most likely missing permission?

Accepted Answer

ec2:CreateNetworkInterface. To start a DMS replication task, the IAM policy must include permissions for DMS to create network interfaces in the VPC. The ec2:CreateNetworkInterface permission is required because DMS dynamically creates an elastic network interface for the replication instance when the task starts. The other options are not the most likely missing permission: dms:CreateReplicationInstance and dms:CreateEndpoint are needed for creating resources, not for starting an existing task; s3:ListBucket is unrelated; kms:Decrypt is only needed if using encrypted endpoints, which is not indicated.

Answer

dms:CreateReplicationInstance and dms:CreateEndpoint

Answer

s3:ListBucket

Answer

kms:Decrypt

Question 5

The exhibit shows the output of the describe-replication-tasks command. The task status is 'failed'. Which action should be taken to troubleshoot the failure?

Accepted Answer

Review the CloudWatch logs for the replication instance and task.. The first step is to check the CloudWatch logs for DMS to find detailed error messages. Option A is wrong because restarting without investigation may lead to the same error. Option B is wrong because modifying table mappings may not be the issue. Option C is wrong because creating a new task without understanding the failure is inefficient.

Answer

Restart the replication task with a different migration type.

Answer

Modify the table mappings to exclude all tables.

Answer

Create a new replication task with the same settings.

Question 6

The exhibit shows a CloudFormation template snippet. During migration, the SAP application server fails to start because the root volume is too small. What is the most efficient fix?

Accepted Answer

Modify the template to increase VolumeSize to 100 and update the stack.. Modifying the template to increase the volume size and updating the stack is the proper Infrastructure as Code approach. Option A is wrong because modifying the volume directly is not recommended for CloudFormation-managed resources. Option C is wrong because stopping the instance is not necessary for volume modification, but the template should be updated. Option D is wrong because deleting and recreating is less efficient.

Answer

Manually resize the EBS volume via the AWS Console and then update the stack.

Answer

Stop the instance, modify the volume size, and start the instance.

Answer

Delete the stack and create a new one with a larger volume.

Question 7

Which TWO AWS services can be used to migrate an on-premises SAP HANA database to AWS with minimal downtime? (Choose 2.)

Accepted Answer

SAP Landscape Transformation (SLT). (SAP Landscape Transformation) is correct because SLT can replicate data in real-time from an on-premises SAP system to SAP HANA on AWS, enabling minimal downtime migration. Option E (SAP HANA System Replication) is correct because HSR provides native, continuous database replication with automatic failover, allowing migration with minimal downtime. Options B (AWS Backup), C (AWS DMS), and D (CloudEndure) are incorrect: AWS Backup is for backup/restore, not continuous replication; DMS does not support SAP HANA as a source; CloudEndure is not recommended for SAP HANA workloads.

Answer

AWS Backup

Answer

AWS Database Migration Service (DMS)

Answer

AWS CloudEndure Migration

Question 8

Which THREE factors should be considered when selecting an EC2 instance type for an SAP HANA production system during migration? (Choose 3.)

Accepted Answer

Memory (RAM) size relative to the HANA workload. Options A, D, and E are correct because SAP HANA is memory-intensive and requires sufficient RAM (A), high network throughput and low latency for data replication and client access (D), and must be run on instance types certified by SAP for HANA workloads (E). Option B is incorrect because GPU acceleration is not a requirement for standard SAP HANA production systems. Option C is incorrect because while EBS-optimized is recommended for consistent performance, it is not a primary selection factor compared to the others.

Answer

GPU acceleration capabilities

Answer

EBS-optimized by default

Question 9

Which TWO AWS services can be used to automate the deployment of SAP infrastructure during migration? (Choose 2.)

Accepted Answer

AWS Service Catalog. AWS CloudFormation allows you to model and provision SAP infrastructure as code using templates. Option B is correct because AWS Service Catalog allows you to create and manage a catalog of approved IT services, including SAP infrastructure templates, which can be deployed in a standardized and automated manner. Option D is wrong because AWS Elastic Beanstalk is a PaaS service that abstracts the underlying OS and is not designed for the specific requirements of SAP deployments, such as kernel patching and custom system configurations. Option A is wrong because AWS OpsWorks uses Chef/Puppet and is not typically used for SAP deployment automation. Option E is wrong because AWS CodePipeline is a CI/CD service, not for infrastructure deployment. So correct answers: B and C.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodePipeline

Question 10

A company is migrating an on-premises SAP ERP system to AWS. The system uses a large Oracle database. The migration must minimize downtime. Which AWS service should be used for the database migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can migrate databases with minimal downtime by using ongoing replication. Option A is incorrect because AWS SMS is designed for server migration, not database migration. Option B is incorrect because AWS Application Migration Service (MGN) is also for server migration. Option C is incorrect because AWS Schema Conversion Tool (SCT) assists with schema and code conversion but is not a full database migration service. Option D is correct because AWS Database Migration Service (DMS) can migrate Oracle databases to AWS with minimal downtime using continuous replication.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Application Migration Service (MGN)

Answer

AWS Schema Conversion Tool (SCT)

Question 11

A company is migrating its SAP environment to AWS and needs to ensure that the SAP systems can communicate with each other using their hostnames without relying on a DNS service. Which AWS feature should be used?

Accepted Answer

Amazon Route 53 private hosted zone. Amazon Route 53 private hosted zones allow DNS resolution for custom domain names (such as hostnames) within Amazon VPCs without requiring an external DNS service. Option A (Network Load Balancer) is incorrect because an NLB distributes incoming traffic across targets, it does not provide DNS resolution. Option B (Security Group rules) is incorrect because security groups act as virtual firewalls to control traffic, not DNS. Option C (VPC Peering) is incorrect because VPC peering connects networks at the IP level but does not offer hostname resolution. Option D is correct because a Route 53 private hosted zone is specifically designed for DNS resolution within VPCs, enabling hostname-based communication between SAP systems.

Answer

Network Load Balancer (NLB)

Answer

Security Group rules

Answer

VPC Peering

Question 12

A company is migrating an SAP HANA database to AWS. The source system uses a Linux filesystem with a specific block size. After migration, the performance is lower than expected. What is the most likely cause?

Accepted Answer

The Amazon EBS volume block size does not match the SAP HANA requirements. SAP HANA on AWS requires the EBS volume to have a block size that matches SAP HANA's requirements (typically 4 KiB). If the source system used a different block size (e.g., 512 bytes), performance degradation can occur. Option A (placement group) affects network latency, not block size performance. Option B (IOPS) is provisioned, but even with sufficient IOPS, block size mismatch can cause poor performance. Option D (encryption) does not impact block size or performance significantly.

Answer

The EC2 instance is not in a placement group

Answer

The Amazon EBS volume is not provisioned with enough IOPS

Answer

The EBS volume encryption is enabled, causing overhead

Question 13

A company is migrating its SAP landscape to AWS and has a requirement to use existing software licenses to reduce costs. Which AWS pricing model should be used?

Accepted Answer

Dedicated Hosts. Dedicated Hosts provide visibility into the underlying physical cores and sockets, enabling you to bring your own existing SAP licenses (e.g., per-core or per-socket) to AWS and reduce costs. Option B (Compute Savings Plans) offers discounts on compute usage but does not support license management. Option C (Reserved Instances) provides capacity reservation and cost savings but does not allow use of your own licenses. Option D (Dedicated Instances) offers instance isolation at the hardware level but does not expose the underlying physical server for license tracking.

Answer

Compute Savings Plans

Answer

Reserved Instances (RI)

Answer

Dedicated Instances

Question 14

A company is migrating SAP applications to AWS and needs to replicate data from on-premises Active Directory to AWS Managed Microsoft AD for authentication. Which AWS service should be used?

Accepted Answer

AWS Directory Service for Microsoft Active Directory. AWS Directory Service for Microsoft Active Directory is the correct service because it provides a managed Active Directory in AWS that can be configured with a forest trust to on-premises Active Directory, enabling replication of directory data. This allows authentication using on-premises credentials in AWS. Option A (AWS Transit Gateway) is for network connectivity, not directory replication. Option C (AWS Resource Access Manager) is used for sharing resources across accounts. Option D (AWS AD Connector) only proxies authentication requests and does not replicate data. Therefore, the best answer is AWS Directory Service for Microsoft Active Directory.

Answer

AWS Transit Gateway

Answer

AWS Resource Access Manager (RAM)

Answer

AWS AD Connector

Question 15

A company is migrating an SAP ERP system to AWS and needs to ensure that the SAP application servers can scale automatically based on CPU utilization. Which AWS service should be used to achieve this?

Accepted Answer

AWS Auto Scaling. AWS Auto Scaling can automatically adjust the number of EC2 instances based on CloudWatch alarms for CPU utilization, making it suitable for scaling SAP application servers. Option A is wrong because Elastic Load Balancing distributes traffic but does not scale instances. Option B is wrong because AWS Lambda is for serverless compute, not for running SAP application servers. Option C is wrong because AWS CloudFormation is an infrastructure-as-code service, not for automatic scaling.

Answer

AWS Elastic Load Balancing (ELB)

Answer

AWS Lambda

Answer

AWS CloudFormation
