PAS-C01 Migration Practice Test 6 — 15 Questions

Question 1

A company is migrating a critical SAP HANA database to AWS and needs to ensure high availability. The SAP HANA system replication will be configured across two Availability Zones. Which AWS service should be used to automate the failover of the SAP HANA database?

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

Accepted Answer

Amazon Route 53. Amazon Route 53 is the correct service because it provides DNS-based failover for SAP HANA system replication. When the primary HANA database in one Availability Zone fails, Route 53 health checks detect the failure and automatically update DNS records to point to the secondary HANA instance in the other AZ. This automates client redirection without manual intervention, ensuring high availability.

Answer

AWS CloudFormation

Answer

AWS Elastic Disaster Recovery (DRS)

Answer

AWS Backup

Question 2

A company is migrating an SAP S/4HANA system to AWS. The system requires high availability for the database and application layers. Which THREE components should the company configure to achieve high availability for SAP S/4HANA on AWS?

Accepted Answer

Pacemaker cluster for SAP Central Services. Option A is correct because SAP Central Services (ASCS/SCS and ERS) must be protected by a Pacemaker cluster with a fencing mechanism (such as an overlay IP and STONITH) so the enqueue and message server roles can fail over automatically between nodes. Option B is correct because SAP HANA high availability on AWS is achieved with a multi-AZ deployment using HANA System Replication (HSR) in an active/standby or active/active (read-enabled) configuration, combined with an overlay IP and cluster manager for automatic takeover. Option D is correct because the SAP transport directory (/usr/sap/trans) must be shared across all application servers, and Amazon EFS provides a highly available, multi-AZ, POSIX-compliant NFS file system that survives an AZ failure, unlike instance-local storage. Option C is not correct because confining the deployment to a single Availability Zone creates a single point of failure and does not provide the required high availability. Option E is not correct because AWS Transit Gateway is a network connectivity hub for VPCs and on-premises links, not an HA mechanism for the SAP database or application layers.

Answer

Single Availability Zone deployment

Answer

AWS Transit Gateway

Question 3

A company is migrating an application to AWS and creates the IAM policy shown in the exhibit. The policy is attached to an IAM user responsible for managing EC2 instances. Which additional permission must be added to allow the user to create new EC2 instances?

Accepted Answer

ec2:RunInstances. The policy allows Describe, Start, and Stop actions but not RunInstances. Option A (ec2:RunInstances) is required to create instances. Option B (ec2:DescribeImages) is for viewing AMIs. Option C (ec2:CreateTags) is for tagging. Option D (ec2:AllocateAddress) is for Elastic IPs.

Answer

ec2:DescribeImages

Answer

ec2:CreateTags

Answer

ec2:AllocateAddress

Question 4

A company is migrating on-premises servers to AWS. After migrating, the administrator runs the AWS CLI command shown in the exhibit. The company wants to ensure that all EC2 instances are in the 'running' state. Which action should the administrator take?

Accepted Answer

Run aws ec2 start-instances --instance-ids i-1a2b3c4d5e6f7g8h. The instance with ID i-1a2b3c4d5e6f7g8h is in a stopped state. To transition it to the 'running' state, the administrator should use the start-instances command. Option A is correct because it starts the stopped instance. Option B (stop-instances) would stop running instances, which is not the desired action. Option C (reboot-instances) would reboot a running instance, but this instance is stopped. Option D (terminate-instances) would permanently delete the instance, which is not the goal.

Answer

Run aws ec2 stop-instances --instance-ids i-0a1b2c3d4e5f6g7h

Answer

Run aws ec2 reboot-instances --instance-ids i-2a3b4c5d6e7f8g9h

Answer

Run aws ec2 terminate-instances --instance-ids i-2a3b4c5d6e7f8g9h

Question 5

A company is migrating a large SAP HANA workload to AWS. The source system runs on IBM Power Systems. They need to ensure that the target AWS infrastructure meets SAP certification requirements. Which EC2 instance type should they choose?

Accepted Answer

x1e.32xlarge. x1e.32xlarge is certified for SAP HANA production workloads. Therefore, Option D is correct. Option A (m5.24xlarge) is a general-purpose instance and not certified for SAP HANA. Option B (c5.18xlarge) is compute-optimized and not suitable for SAP HANA's memory requirements. Option C (i3en.24xlarge) is storage-optimized and not SAP HANA certified.

Answer

m5.24xlarge

Answer

c5.18xlarge

Answer

i3en.24xlarge

Question 6

An organization is migrating a legacy SAP ERP system to AWS. The current system runs on IBM AIX with Oracle Database. They plan to use SAP HANA on AWS. Which AWS service should they use to assess the source system's readiness and generate a migration plan?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) is the correct service for assessing source system readiness and generating a migration plan for SAP systems to AWS. It provides automated readiness checks and migration orchestration. Option A (AWS CloudEndure Migration) is a predecessor of AWS MGN and is now integrated; it is not the recommended current service. Option C (AWS Database Migration Service - DMS) is for database migration only, not full system assessment. Option D (AWS Schema Conversion Tool - SCT) handles schema conversion, not assessment or migration planning.

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (DMS)

Answer

AWS Schema Conversion Tool (SCT)

Question 7

A company is migrating its SAP HANA database to AWS. They need to validate that the target AWS environment meets SAP's certification requirements. Which two steps should they take? (Choose TWO.)

Accepted Answer

Confirm that the operating system is SAP certified for HANA. Option D is correct because SAP HANA certification is tied to specific operating system versions and distributions (for example, SUSE Linux Enterprise Server or Red Hat Enterprise Linux versions listed in the SAP HANA hardware directory), so the OS must be confirmed as SAP certified for HANA before the environment can be considered compliant. Option E is correct because SAP certifies HANA only on specific EC2 instance types (such as the memory-optimized X1, X1e, High Memory, or U-series instances listed in the SAP HANA Certified and Supported Instance Types documentation), so verifying the instance type against that list is a mandatory validation step. Option A is not required because SAP HANA certification does not mandate a fixed 10 Gbps network bandwidth; certified instance types may have different network capabilities, and bandwidth is not the certification criterion. Option B is not required because using an SAP HANA AMI from AWS Marketplace is a convenience for deployment, not a validation step for SAP certification requirements. Option C is not required because EBS optimization and high throughput are performance considerations, not part of SAP's formal HANA certification criteria for the target environment.

Answer

Configure the instance with 10 Gbps network bandwidth

Answer

Use an Amazon Machine Image (AMI) from the AWS Marketplace that includes SAP HANA

Answer

Ensure that the EBS volumes are optimized for high throughput

Question 8

A company is migrating a large SAP ERP system to AWS using SAP HANA. They want to minimize downtime and ensure consistency. Which three approaches should they combine? (Choose THREE.)

Accepted Answer

Use AWS Snowball Edge for the initial data transfer. Option A is correct because AWS Snowball Edge provides a physical, high-capacity data transfer appliance that is ideal for seeding very large SAP HANA datasets to AWS without saturating network links, which is essential for minimizing initial migration time. Option D is correct because AWS DMS with change data capture (CDC) continuously replicates ongoing changes from the source database to the target, keeping the systems synchronized and reducing cutover downtime. Option E is correct because SAP HANA system replication natively synchronizes the primary and secondary HANA instances, ensuring data consistency and enabling a controlled, low-downtime failover to the AWS target. Option B is not appropriate here because AWS DataSync is designed for file and object data movement, not for SAP HANA database replication. Option C is not appropriate because AWS Server Migration Service (SMS) replicates whole VMs/servers and does not provide the database-level consistency and CDC needed for a SAP HANA migration.

Answer

Use AWS DataSync for ongoing replication

Answer

Use AWS Server Migration Service (SMS) for server replication

Question 9

A company is migrating its SAP environment to AWS. They need to choose the right storage for SAP HANA data and log volumes. Which two storage types are SAP HANA certified on AWS? (Choose TWO.)

Accepted Answer

Amazon EBS gp3 volumes. Amazon EBS gp3 volumes (option B) are SAP HANA certified on AWS and are commonly used for SAP HANA data and log volumes, providing SSD-backed, general-purpose performance with independently configurable IOPS and throughput. Amazon EBS io2 volumes (option D) are also SAP HANA certified and are designed for high-performance, high-durability workloads, offering up to 99.999% durability and high IOPS, making them suitable for demanding SAP HANA data and log volumes. Instance store volumes (option A) are not SAP HANA certified for data and log volumes because they are ephemeral and data is lost if the instance stops or terminates. Amazon S3 (option C) is object storage and cannot be used as block storage for SAP HANA data and log volumes. Amazon EFS (option E) is a shared file storage service and is not certified or suitable for SAP HANA data and log volumes, which require block-level storage.

Answer

Instance store volumes

Answer

Amazon S3

Answer

Amazon EFS

Question 10

A global company is migrating its SAP ERP system to AWS. The system runs SAP ECC on IBM AIX with Oracle Database. The company plans to move to SAP S/4HANA on AWS. The source system is 5 TB in size. The network bandwidth between the on-premises data center and AWS is 100 Mbps. The migration must be completed within a 2-week window with minimal downtime. The company has a SAP license that allows running S/4HANA on certified hardware. They have already used AWS SCT to convert the database schema to SAP HANA-compatible format. They now need to execute the data migration. The team is considering the following options:

Option A: Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover.
Option B: Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA.
Option C: Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA.
Option D: Use SAP HANA system replication from the source Oracle database to the target HANA database.

Which option is the most feasible and efficient for this migration?

Accepted Answer

Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover. AWS DMS with ongoing replication from Oracle to HANA allows continuous data synchronization with minimal downtime, and a final cutover can be performed within the 2-week window. Given the 5 TB size and 100 Mbps bandwidth, a full transfer would take over 4 days, but DMS can handle initial load and change data capture (CDC) efficiently. This approach is the most feasible for minimal downtime.

Answer

Use SAP HANA system replication from the source Oracle database to the target HANA database

Answer

Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA

Answer

Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA

Question 11

A mid-size company is migrating its SAP Business One on SAP HANA to AWS. The current system runs on a single server with 256 GB RAM and uses a local disk for HANA data. The company wants to minimize capital expenditure and operational overhead. They have already sized the target EC2 instance as an x1e.2xlarge (122 GB RAM) but later realized that SAP HANA requires at least 256 GB RAM for their workload. The migration deadline is in one week. The company has a limited budget and cannot change the instance type to a larger one due to procurement delays. They have an 8 TB EBS gp2 volume attached for HANA data, but it is not meeting performance requirements. The team proposes the following actions:

Option A: Increase the EBS volume size to 16 TB to improve IOPS.
Option B: Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data.
Option C: Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore.
Option D: Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA.

Which option is the best course of action considering the constraints?

Accepted Answer

Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore. The best because it recommends using an instance with instance store SSDs. Although the option mentions i3en.2xlarge as an example, the team can select a larger instance in the same family (e.g., i3en.8xlarge with 256 GB RAM) to meet the memory requirement. SAP HANA backup and restore is a valid migration method. Options A and B do not resolve the memory constraint, and Option D keeps the undersized x1e.2xlarge (122 GB RAM), which is insufficient for the HANA workload.

Answer

Increase the EBS volume size to 16 TB to improve IOPS

Answer

Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA

Answer

Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data

Question 12

A company is migrating an SAP HANA database to AWS. The database is 2 TB in size and runs on a single server. The company needs to minimize downtime during the migration. Which AWS service should be used for the initial data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is a physical device designed for large-scale data transfer, allowing the 2 TB SAP HANA database to be shipped to AWS, bypassing network limitations and minimizing downtime. Option B is incorrect because AWS DMS with ongoing replication is intended for continuous synchronization after initial load, not for the initial bulk transfer, and still relies on network speed. Option C is incorrect because AWS Direct Connect provides a dedicated network connection but does not eliminate transfer time for large datasets like 2 TB. Option D is incorrect because Amazon S3 Transfer Acceleration speeds up uploads over the public internet, but for 2 TB, network transfer would still be slower and less predictable than a physical device.

Answer

AWS Database Migration Service (DMS) with ongoing replication

Answer

AWS Direct Connect

Answer

Amazon S3 Transfer Acceleration

Question 13

An SAP system on AWS is experiencing high latency between the SAP application servers and the HANA database. The application servers are in a different Availability Zone than the database. Which change should a migration specialist recommend to reduce latency without increasing costs significantly?

Accepted Answer

Deploy SAP application servers in the same placement group and Availability Zone as the HANA database. Deploying the SAP application servers in the same placement group and Availability Zone as the HANA database is correct because network latency between Availability Zones is typically 1-2 ms, while intra-AZ latency is sub-millisecond. A cluster placement group packs instances close together in a single AZ to reduce latency further. This change directly addresses the latency issue without significant cost increase, as it only requires re-deploying instances in the same AZ.

Answer

Enable Enhanced Networking on all instances

Answer

Create a VPC Peering connection between the application and database subnets

Answer

Use larger instance types for the application servers

Question 14

During an SAP migration, the migration team needs to ensure that all SAP system IDs (SIDs) are unique across the AWS environment. Which AWS service can be used to centrally manage and enforce this uniqueness?

Accepted Answer

AWS Service Catalog. AWS Service Catalog lets administrators create and govern a curated catalog of approved products (including SAP system deployments) with constraints and tagging policies, which can enforce naming conventions and uniqueness of SAP SIDs at provisioning time. By controlling the provisioning templates and applying constraints, the organization ensures no two deployments use the same SID. This centralizes governance and prevents non-compliant or duplicate SID deployments.

Answer

AWS Config

Answer

AWS Resource Access Manager

Answer

AWS CloudTrail

Question 15

A company is migrating an SAP system to AWS and needs to ensure high availability for SAP Central Services (ASCS) and Enqueue Replication Server (ERS). Which architecture meets SAP's high availability requirements?

Accepted Answer

Use a cluster solution with a shared file system and a virtual IP address in a multi-AZ setup. SAP-certified high availability for ASCS/ERS requires an OS-level cluster (Pacemaker/Corosync on SUSE or Red Hat) that manages a virtual IP (overlay IP) and a shared file system (/sapmnt and the enqueue replication directory) across two nodes in separate Availability Zones. The virtual IP moves with the ASCS/ERS resource during failover, and the shared file system (typically Amazon EFS or FSx for SAP HANA) ensures both nodes see the same SAP global directories and enqueue state. This multi-AZ, cluster-managed design is what SAP and AWS document as the reference HA architecture.

Answer

Deploy ASCS and ERS in a single Availability Zone with an automatic restart

Answer

Use an Application Load Balancer to distribute traffic between ASCS and ERS

Answer

Configure Amazon Route 53 health checks to failover between ASCS and ERS
