PAS-C01 Migration Practice Test 18 — 15 Questions

Question 1

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) is correct because it enables the migration of SAP HANA, SAP ASE, or other SAP-supported databases to AWS with minimal downtime. DMS supports homogeneous migrations (e.g., SAP HANA to SAP HANA on Amazon RDS or EC2) and heterogeneous migrations (e.g., SAP ASE to SAP HANA) when paired with the Schema Conversion Tool (SCT). It handles ongoing replication via Change Data Capture (CDC), which is critical for SAP systems that cannot tolerate extended outages.

Answer

AWS CloudTrail

Answer

AWS Direct Connect

Question 2

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

Accepted Answer

Storage performance and IOPS requirements. The two critical considerations when planning an SAP migration to AWS are storage performance (IOPS) and network connectivity/latency. Storage performance is critical because SAP databases require high IOPS for optimal performance, and insufficient IOPS can lead to significant degradation. Network connectivity and latency between SAP components (e.g., application servers and database) are also critical to ensure low-latency communication and avoid performance bottlenecks. Option B (AWS Region availability) is not as critical because SAP can run in any region that supports required services, though it may affect latency. Option C (database compatibility) is important but a separate migration decision, not a top-level planning consideration. Option E (number of security groups) is a security configuration detail, not a critical factor for migration planning.

Answer

AWS Region availability for SAP services

Answer

Database compatibility with target

Answer

Number of security groups allowed

Question 3

A company is migrating a large Oracle database to Amazon RDS for Oracle. They want to minimize downtime during the migration. Which AWS service should they use to replicate data in real time?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS (Database Migration Service) supports ongoing replication with minimal downtime, making it ideal for migrating large databases like Oracle to Amazon RDS for Oracle while keeping the source and target in sync. Option A (AWS SMS) is for server migration, not database replication. Option B (AWS SCT) is a schema conversion tool, not for real-time data replication. Option D (AWS DataSync) is for file-based data transfer, not database replication.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS DataSync

Question 4

A company is migrating a Windows-based .NET application to AWS. The application currently uses Active Directory for authentication. Which AWS service should they use to maintain a similar authentication experience?

Accepted Answer

AWS Directory Service for Microsoft Active Directory. AWS Directory Service for Microsoft Active Directory provides a managed Microsoft Active Directory in the AWS cloud, allowing the application to authenticate against Active Directory without changes. Option A is correct. Option B (Simple AD) is a Samba-based directory, not fully compatible with all .NET AD features. Option C (IAM) manages access to AWS resources, not application authentication. Option D (Cognito) is for external user pools, not enterprise AD integration.

Answer

AWS Directory Service Simple AD

Answer

AWS Identity and Access Management (IAM)

Answer

Amazon Cognito

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 an on-premises application to AWS. The application requires low-latency access to a shared file system that can be mounted by multiple EC2 instances simultaneously. Which storage solution should they use?

Accepted Answer

Amazon Elastic File System (EFS). Amazon EFS provides a scalable, shared file system for multiple EC2 instances. Option A is correct. Option B is wrong because EBS volumes can be attached to only one instance. Option C is wrong because S3 is object storage, not a file system. Option D is wrong because Instance Store is ephemeral.

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon Simple Storage Service (S3)

Answer

Amazon EC2 Instance Store

Question 7

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. SAP on AWS supports both HANA Large Instances and certified EC2 instances. Since the custom kernel is not supported on HANA Large Instances, the best approach is to use an SAP-certified EC2 instance that can accommodate the existing kernel. Option C is correct because it avoids the unsupported kernel issue without requiring a kernel update. Option A is incorrect because HANA Large Instances do not support the custom kernel. Option B is incorrect because contacting SAP for a supported kernel may not be feasible within the weekend migration timeframe. Option D is incorrect because re-platforming to a supported kernel introduces additional risk and complexity.

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 8

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 9

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

Question 10

A company is migrating a critical SAP HANA database to AWS. The database size is 2 TB. They require the highest network throughput and low latency between EC2 instances. Which EC2 placement strategy should they use?

Accepted Answer

Cluster Placement Group. Placement Groups with Cluster Placement provide low latency and high throughput within a single AZ. Option D (Cluster Placement Group) is correct. Option A (Spread Placement Group) is for high availability, not performance. Option B (Partition Placement Group) is for large distributed systems. Option C (Dedicated Hosts) provides licensing benefits, not network performance.

Answer

Spread Placement Group across multiple Availability Zones

Answer

Partition Placement Group

Answer

Dedicated Hosts

Question 11

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. Using AWS DMS with ongoing replication and performing a cutover ensures data consistency and minimizes downtime during the migration. DMS replicates changes in real-time, allowing a final cutover with zero data loss. Option A (Oracle UNLOAD and COPY) requires significant downtime for export/import. Option C (Amazon Kinesis) is for streaming, not bulk migration. Option D (AWS SCT for schema conversion) only handles schema, not data transfer.

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 12

Question 13

Which THREE factors should be considered when selecting an AWS Region for a migration to minimize latency for users in Europe? (Choose three.)

Accepted Answer

Data residency and compliance requirements. Data residency and compliance requirements (Option A) are critical when selecting an AWS Region for a migration to minimize latency for users in Europe because many European countries have strict data sovereignty laws (e.g., GDPR) that mandate personal data remain within the EU/EEA. Choosing a Region outside Europe would violate these regulations, regardless of latency benefits, and could result in legal penalties. Therefore, compliance directly influences which Regions are permissible, making it a primary factor in Region selection.

Answer

Number of Availability Zones in the Region

Answer

Cost of data transfer between Regions

Question 14

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 (Option B) allow you to automatically transition SAP backup and archival data from S3 Standard to lower-cost storage classes like S3 Standard-IA or S3 Glacier, reducing storage costs without manual intervention. This is critical for SAP workloads where large volumes of backup data accumulate over time and do not require immediate access.

Answer

AWS Storage Gateway for on-premises caching

Answer

Amazon S3 Standard for all data

Question 15

A company is migrating a legacy on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime. Which AWS service should they use for ongoing replication during the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) with ongoing replication (change data capture) allows near-zero downtime migration. Option A (AWS Schema Conversion Tool) is wrong because it is a schema conversion tool, not a replication service. Option B (AWS Server Migration Service) is wrong because it is for server migration, not database replication. Option D (AWS DataSync) is wrong because it is for file/object storage, not database replication.

Answer

AWS Schema Conversion Tool (SCT)
