PAS-C01 Migration Practice Test 10 — 15 Questions

Question 1

A company is migrating its SAP environment to AWS and needs to ensure that the SAP license compliance is maintained. What should the company do to verify that the EC2 instances used for SAP are properly licensed?

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

Accepted Answer

Use EC2 instance types listed in the SAP Certified and Supported SAP HANA Hardware Directory. The SAP Certified and Supported SAP HANA Hardware Directory lists all EC2 instance types that are certified by SAP for running SAP HANA and other SAP applications. Using only these instance types ensures that the underlying hardware meets SAP's performance and reliability requirements, which is essential for license compliance because SAP licenses are often tied to the hardware's processing power (e.g., SAPS). AWS License Manager can enforce license limits but does not verify that the instance type is certified for SAP. BYOL is a licensing model, not a verification method. AWS Config rules can check instance types but would need a custom rule referencing the directory; it's not the primary method.

Answer

Use AWS License Manager to enforce license limits

Answer

Use only bring-your-own-license (BYOL) instances

Answer

Use AWS Config rules to check instance types

Question 2

Which TWO AWS services can be used to migrate on-premises SAP systems to AWS? (Choose 2.)

Accepted Answer

AWS Server Migration Service (SMS). AWS Server Migration Service (SMS) is correct because it is an agentless service designed to migrate on-premises virtual machines, including SAP application servers, to AWS by replicating live server volumes and launching them as EC2 AMIs, which fits the lift-and-shift migration of SAP systems. AWS Database Migration Service (DMS) is correct because it migrates on-premises SAP databases (such as SAP-certified Oracle, SQL Server, or SAP ASE) to AWS RDS or EC2-hosted databases with minimal downtime, supporting both homogeneous and heterogeneous migrations. AWS Schema Conversion Tool (SCT) is not one of the two answers here because it is a companion tool for converting database schemas during heterogeneous migrations rather than a standalone migration service for SAP systems. AWS Direct Connect is a dedicated network connection service, not a migration service, so it does not perform the migration itself. Amazon CloudFront is a content delivery network and has no role in migrating on-premises SAP systems to AWS.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Direct Connect

Answer

Amazon CloudFront

Question 3

Which THREE AWS services are typically used in the migration of an SAP environment to AWS? (Choose 3.)

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) (A) is correct because it migrates the SAP database tier (e.g., Oracle, SQL Server, or SAP ASE) to Amazon RDS or EC2 with minimal downtime, supporting both homogeneous and heterogeneous migrations. AWS Server Migration Service (SMS) (D) is correct because it performs agentless, incremental replication of on-premises SAP application and database servers (VMware vSphere, Hyper-V, or Azure) into EC2 AMIs, which is the standard lift-and-shift mechanism for SAP hosts. AWS Schema Conversion Tool (SCT) (E) is correct because it converts the source database schema and code (e.g., Oracle PL/SQL to PostgreSQL PL/pgSQL) when migrating SAP to a different database engine on AWS, complementing DMS. AWS CloudTrail (B) is not a migration service; it only records API activity for auditing and governance. AWS Direct Connect (C) provides dedicated network connectivity that may support data transfer during a migration, but it is a networking service, not a migration service itself.

Answer

AWS CloudTrail

Answer

AWS Direct Connect

Question 4

Which TWO considerations are critical when planning a migration of an SAP system to AWS? (Choose 2.)

Accepted Answer

Storage performance and IOPS requirements. Option A is correct because SAP workloads (especially the database tier, e.g., SAP HANA or Oracle) are highly sensitive to storage throughput and IOPS, so sizing Amazon EBS volumes (gp3, io1/io2) to meet SAP's KPIs for disk latency and IOPS is a critical migration planning factor. Option D is correct because SAP architectures distribute components (ASCS, application servers, database) across subnets and often across Availability Zones, so network connectivity and inter-component latency via VPC design, placement groups, and Direct Connect/VPN must be validated to avoid performance degradation. Option B is not essential since SAP services are available in most AWS Regions and Region selection is a general deployment choice rather than a migration-critical SAP consideration. Option C is not a migration-specific concern because the target database platform is typically preserved or already decided by the SAP migration strategy, not a new compatibility question. Option E is irrelevant because security group quotas are soft limits that can be raised via Service Quotas and do not drive SAP migration planning.

Answer

AWS Region availability for SAP services

Answer

Database compatibility with target

Answer

Number of security groups allowed

Question 5

A company plans to migrate a 10 TB on-premises SQL Server database to Amazon RDS for SQL Server. The migration must be completed within a 4-hour window. The network bandwidth is 1 Gbps. Which migration approach should they choose?

Accepted Answer

Use AWS Snowball Edge to transfer data and then perform a cutover. AWS SCT only converts schema, not data; export/import via native tools would still need to transfer the full 10 TB over the internet, which at 1 Gbps takes ~22 hours, far exceeding the 4-hour window. Option B is incorrect because DMS over the internet is limited by the 1 Gbps bandwidth, resulting in a transfer time of ~22 hours, too slow. Option C is incorrect because while Direct Connect provides a dedicated connection, it still has a 1 Gbps bandwidth limit, so the transfer would still take ~22 hours, exceeding the window. Option D is correct because AWS Snowball Edge physically ships the data, bypassing network bandwidth limitations, and allows a fast cutover.

Answer

Use AWS SCT to convert schema and then export/import via native tools

Answer

Use AWS DMS over the internet

Answer

Set up an AWS Direct Connect connection and use DMS

Question 6

A company is migrating a legacy SAP ERP system to AWS. The migration must be completed over a weekend to minimize business impact. The SAP application relies on a custom kernel that is not supported by the AWS SAP HANA Large Instances. What is the best approach?

Accepted Answer

Use an SAP-certified EC2 instance with the existing kernel. The scenario states the SAP application relies on a custom kernel that is not supported by SAP HANA Large Instances — so the migration must avoid HLI and instead use an SAP-certified EC2 instance type that can run the existing custom kernel. SAP-certified EC2 instances (e.g., X1, X1e, X2, M5, R5 families certified for SAP) support standard OS kernels and can host the legacy SAP ERP system without forcing a kernel change, allowing the weekend cutover to proceed. This is the best approach because it preserves the application's kernel dependency while still moving to AWS.

Answer

Migrate to SAP HANA Large Instances and update the kernel

Answer

Contact SAP to obtain a supported kernel version

Answer

Re-platform the application to use a supported kernel

Question 7

An organization is migrating a multi-tier application to AWS. The web tier runs on EC2 instances behind an Application Load Balancer. The database tier uses a self-managed MySQL instance on EC2. To achieve high availability, they plan to use Multi-AZ deployment. Which migration step should they prioritize to ensure minimal downtime?

Accepted Answer

Set up continuous replication using DMS and perform a cutover. Setting up continuous replication using AWS DMS (Database Migration Service) ensures data is synchronized between the source and target databases with minimal lag. This allows a quick cutover, significantly reducing downtime during migration. Option A is correct. Option B is not prioritized for minimal downtime as snapshots require downtime to restore. Option C is wrong because a one-time full load alone would miss ongoing changes, causing data loss. Option D defeats the high-availability goal by not using Multi-AZ from the start.

Answer

Configure Amazon EBS snapshots for the database volume

Answer

Use AWS DMS for one-time full load only

Answer

Launch the database in a single Availability Zone first

Question 8

A company wants to migrate its on-premises VMware virtual machines to AWS. They need to retain the current operating system and applications. Which AWS service should they use?

Accepted Answer

AWS Server Migration Service (SMS). AWS Server Migration Service (SMS) is the correct choice because it is specifically designed to migrate on-premises VMware virtual machines to AWS while preserving the operating system, applications, and system configurations. It uses agentless replication via the VMware vCenter connector to create Amazon Machine Images (AMIs) from the source VMs, enabling a lift-and-shift migration without reinstallation or reconfiguration.

Answer

AWS Application Migration Service (MGN)

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Question 9

A company is migrating a 5 TB Oracle data warehouse to Amazon Redshift. They need to minimize downtime and ensure data consistency. Which migration approach should they use?

Accepted Answer

Use AWS DMS with ongoing replication and perform a cutover. AWS DMS with ongoing replication (change data capture) allows continuous replication of changes from Oracle to Redshift while the initial full load is performed. This minimizes downtime because the source remains operational during migration, and a cutover can be performed once replication lag is near zero, ensuring data consistency. It is the recommended approach for minimizing downtime in large migrations.

Answer

Export data using Oracle UNLOAD and COPY into Redshift

Answer

Stream data using Amazon Kinesis and then load into Redshift

Answer

Use AWS SCT to convert schema and then manually copy data

Question 10

Which TWO AWS services can be used to migrate on-premises virtual machines to AWS without requiring agent installation? (Choose two.)

Accepted Answer

AWS Application Migration Service (MGN) agentless mode. Option D is correct because AWS Application Migration Service (MGN) supports an agentless mode (via the MGN Connector / vCenter-based agentless replication) that migrates on-premises VMware VMs to AWS without installing the AWS Replication Agent on each source VM. Option E is correct because AWS Server Migration Service (SMS) is an agentless service that uses a Server Migration Connector appliance deployed in the on-premises vCenter/VMware environment to replicate VM snapshots to AWS without installing agents on the individual VMs. Option A is not correct here because CloudEndure Migration (now largely superseded by MGN) relies on installing the CloudEndure Agent on each source machine. Option B is not correct because AWS DMS is a database migration service, not a VM migration service, and it requires replication instances/endpoints rather than performing agentless VM migration. Option C is not correct because MGN with agent explicitly requires installing the AWS Replication Agent on each source VM, which contradicts the 'without requiring agent installation' requirement.

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (DMS)

Answer

AWS Application Migration Service (MGN) with agent

Question 11

A company is migrating a large-scale SAP environment to AWS. Which THREE AWS services can be used to optimize storage costs for SAP workloads? (Choose three.)

Accepted Answer

Amazon S3 Lifecycle policies to transition data. Amazon S3 Lifecycle policies (B) are correct because they automatically transition objects between storage classes (e.g., Standard to Standard-IA or Glacier) or expire them after defined periods, directly reducing storage costs for SAP data that ages out of frequent access. Amazon S3 Glacier (D) is correct because it provides very low-cost archival storage ideal for long-term SAP backups and compliance data that is rarely retrieved, with retrieval times from minutes to hours. Amazon EBS Snapshots (E) are correct because they are incremental, storing only blocks changed since the last snapshot, which minimizes backup storage consumption and cost for SAP volumes compared to full backups. AWS Storage Gateway (A) is not among the correct answers because it is a hybrid caching/file-gateway service for on-premises integration, not a primary mechanism for optimizing storage costs of SAP workloads on AWS. Amazon S3 Standard for all data (C) is incorrect because keeping all data in S3 Standard forgoes cheaper tiers such as S3 Standard-IA, S3 One Zone-IA, and Glacier, thereby increasing rather than optimizing storage costs.

Answer

AWS Storage Gateway for on-premises caching

Answer

Amazon S3 Standard for all data

Question 12

A company is migrating an SAP landscape to AWS. They have a requirement to retain the same hostnames and IP addresses for the SAP application servers after migration. How can they achieve this?

Accepted Answer

Use VPC endpoints to assign private IPs. To retain hostnames and IP addresses after migration, you can use VPC endpoints to assign private IPs from the VPC subnet to the SAP application servers. Then, configure a private hosted zone in Amazon Route 53 to map the existing hostnames to these static private IPs. This ensures that applications can continue using the same hostnames and IPs. Option A is incorrect because NAT Gateways are used for outbound traffic and do not assign static IPs. Option C is incorrect because Elastic IP addresses are public and do not retain private IPs. Option D is incorrect because AWS Global Accelerator provides anycast IPs for traffic acceleration, not static private IPs for instances.

Answer

Use a NAT Gateway and assign public IPs

Answer

Use Elastic IP addresses and a private hosted zone in Amazon Route 53

Answer

Use AWS Global Accelerator to assign static IP addresses

Question 13

A company is migrating an SAP BusinessObjects environment to AWS. They need to ensure that the business intelligence reports continue to run without interruption. Which migration strategy should they use?

Accepted Answer

Use a phased migration, moving reports gradually using AWS DataSync. A phased migration using AWS DataSync allows the company to gradually move SAP BusinessObjects reports while maintaining continuous operations. DataSync efficiently transfers large volumes of data over the network with built-in validation and incremental sync capabilities, ensuring that the BI environment remains available during the migration. This approach minimizes disruption by avoiding a full cutover and allows for testing and rollback if needed.

Answer

Rehost using AWS Server Migration Service (SMS) in a single wave

Answer

Replatform to Amazon QuickSight

Answer

Lift-and-shift all servers at once during a maintenance window

Question 14

A company is migrating an on-premises SAP HANA database to AWS. They want to use AWS DMS for ongoing replication. Which TWO prerequisites must be met before starting the replication? (Choose TWO.)

Accepted Answer

The source database must have binary logging enabled (for CDC).. Option B is correct because AWS DMS change data capture (CDC) for ongoing replication requires the source database to have the necessary logging enabled — for SAP HANA this means activating the HANA audit/trigger-based CDC mechanisms (or equivalent binary/transaction logging) so DMS can read ongoing changes. Option C is correct because the DMS replication instance must have network connectivity to the source database (via VPC, security groups, routing, and appropriate ports) in order to read data and apply changes. Option A is incorrect because the source database does not have to run on EC2; DMS supports on-premises sources as long as connectivity exists. Option D is incorrect because the target does not have to be Amazon RDS for Oracle; DMS supports multiple targets and the scenario does not require Oracle. Option E is incorrect because AWS SCT schema conversion is not a prerequisite for DMS replication; it is a separate migration step and not required to start ongoing replication.

Answer

The source database must be running on an EC2 instance.

Answer

The target database must be Amazon RDS for Oracle.

Answer

The schema must be converted using AWS SCT first.

Question 15

A company is migrating an SAP system to AWS. They need to ensure high availability for the SAP Central Services (ASCS/ERS). Which THREE components are required for a highly available SAP ASCS/ERS setup on AWS? (Choose THREE.)

Accepted Answer

A cluster manager (e.g., Pacemaker). Option A is correct because a cluster manager such as Pacemaker (often with Corosync and STONITH/fencing) is required to orchestrate failover of the ASCS and ERS instances, manage resources, and enforce node health in a highly available SAP setup on AWS. Option D is correct because ASCS/ERS require shared storage for SAP global files, profiles, and the enqueue replication, so a shared file system like Amazon FSx for Windows File Server or Amazon EFS (or FSx for NetApp ONTAP) is needed to make the data accessible from both cluster nodes. Option E is correct because a virtual IP (VIP) implemented with an Elastic IP address allows clients and SAP instances to reconnect to the ASCS/ERS after failover without changing the SAP profile or host configuration. Option B is not correct because an Application Load Balancer operates at the HTTP/HTTPS layer and cannot handle the SAP ASCS/ERS protocols (such as SAP GUI, RFC, or enqueue traffic) or provide the required cluster VIP failover semantics. Option C is not correct because Route 53 health checks provide DNS-based failover, which is too slow and not the mechanism used for ASCS/ERS high availability; the cluster manages the VIP directly via the Elastic IP.

Answer

An Application Load Balancer

Answer

Amazon Route 53 health checks
