PAS-C01 Migration Practice Test 12 — 15 Questions

Question 1

A company is migrating an on-premises data center to AWS. The company needs to transfer 50 TB of data to Amazon S3. Which TWO AWS services can be used for this data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is a petabyte-scale data transport solution that uses secure physical devices to transfer large amounts of data into and out of AWS. For a 50 TB migration, Snowball Edge provides a faster and more reliable option than internet-based transfers, as it avoids bandwidth limitations and long transfer times. The device is shipped to the customer, data is copied locally, and then returned to AWS for ingestion into Amazon S3.

Answer

AWS Application Migration Service (MGN)

Answer

AWS CloudFormation

Answer

AWS Database Migration Service (DMS)

Question 2

A company is migrating a web application to AWS and wants to improve security. The application uses a classic three-tier architecture. Which TWO security measures should the company implement?

Accepted Answer

Use AWS WAF to protect the web tier. Using security groups as a virtual firewall (Option E) and AWS WAF to protect against common web exploits (Option D) are both security best practices. Option A (Direct internet access for database tier) is insecure. Option B (S3 Transfer Acceleration) is for speed, not security. Option C (Place all tiers in public subnets) is insecure.

Answer

Allow direct internet access to the database tier

Answer

Use Amazon S3 Transfer Acceleration

Answer

Place all tiers in public subnets

Question 3

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. To achieve high availability for SAP S/4HANA on AWS, three components are required. A Pacemaker cluster (option A) manages SAP Central Services (ASCS and ERS) by automating failover. Multi-AZ deployment for SAP HANA (option B) ensures database high availability by replicating across Availability Zones. Amazon EFS (option D) provides a shared file system for the SAP transport directory, essential for consistent failover. Option C (Single Availability Zone) lacks redundancy, and option E (AWS Transit Gateway) is a networking component unrelated to high availability.

Answer

Single Availability Zone deployment

Answer

AWS Transit Gateway

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 SAP applications to AWS and uses the CloudFormation template snippet shown in the exhibit. The SAP ASCS instance requires a shared file system for the transport directory. However, the template does not create any shared storage. Which AWS resource should be added to the template to provide a shared file system?

Accepted Answer

Amazon EFS file system. Amazon EFS provides a scalable, shared file system that can be mounted across multiple EC2 instances, making it suitable for the SAP transport directory. Option C (Additional EBS volume) is block storage that can only be attached to a single instance, not shared. Option D (Amazon S3 bucket) is object storage, not a file system. Option B (Instance Store) is ephemeral and not shared.

Answer

Instance Store

Answer

Additional Amazon EBS volume

Answer

Amazon S3 bucket

Question 6

A company is migrating its on-premises Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service should they use for the initial data load and ongoing replication?

Accepted Answer

AWS Database Migration Service (DMS). **Option A (AWS Snowball Edge):** Incorrect because Snowball Edge is designed for offline data transfer, not for ongoing replication with minimal downtime. It could be used for initial data load but does not support continuous replication.

**Option B (AWS DMS):** Correct. AWS Database Migration Service can perform a full load of the source Oracle database to Amazon RDS for Oracle and then continuously replicate changes using Change Data Capture (CDC) to minimize downtime and ensure consistency.

**Option C (AWS DataSync):** Incorrect because DataSync is used for file-based data transfers (e.g., NFS/SMB shares), not for database replication.

**Option D (AWS SCT):** Incorrect because the Schema Conversion Tool only converts database schemas and code; it does not handle data migration or replication.

Answer

AWS Snowball Edge

Answer

AWS DataSync

Answer

AWS Schema Conversion Tool (SCT)

Question 7

An organization is migrating a legacy Windows-based .NET application to AWS. The application currently uses IIS and SQL Server on a single server. They want to minimize changes to the application code. Which migration strategy is most appropriate?

Accepted Answer

Rehost the application on Amazon EC2 with the same OS and database. Rehosting (lift-and-shift) involves moving the application to AWS as-is, typically using Amazon EC2, which minimizes code changes. Option B is correct. Option A (Replatform) would involve moving to Amazon RDS for SQL Server and Elastic Beanstalk, which may require some configuration changes. Option C (Refactor) would require significant code changes to adopt microservices. Option D (Repurchase) means buying a new SaaS product, which is not minimal change.

Answer

Replatform by moving to Amazon RDS for SQL Server and Elastic Beanstalk

Answer

Refactor the application to use a microservices architecture

Answer

Repurchase by moving to a SaaS-based application

Question 8

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 9

A company plans to migrate 50 TB of archived data from on-premises tape storage to Amazon S3 Glacier Deep Archive. The data is rarely accessed. Which migration method is most cost-effective and suitable for the data volume?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is a physical device that can transfer large amounts of data offline, avoiding high network costs. For 50 TB, Snowball Edge is cost-effective and efficient. Option C is correct. Option A (AWS DataSync) is for network-based transfers, which may be slow and costly for 50 TB. Option B (AWS CLI with multipart upload) would require significant network bandwidth and time. Option D (AWS Database Migration Service) is for database migration.

Answer

AWS DataSync

Answer

AWS CLI with multipart upload

Answer

AWS Database Migration Service (DMS)

Question 10

A company is migrating their SAP Business Suite on SAP HANA to AWS. They need to transfer the data securely and efficiently. The source environment is in a different country with limited network bandwidth. The total data size is 100 TB. What is the most efficient migration approach?

Accepted Answer

Use AWS Snowball Edge for the initial data load, then AWS DMS for ongoing replication. For a 100 TB migration with limited network bandwidth, an offline transfer using AWS Snowball Edge is most efficient for the initial data load. After loading the data into AWS, AWS DMS can handle ongoing replication for any changes. This approach avoids the time and bandwidth constraints of network-based transfers. Option A (Direct Connect + DMS) would still require significant network time for the full load. Option C (VPN + DMS) is also network-bound and slow. Option D (DataSync over internet) is not efficient for 100 TB.

Answer

Establish an AWS Direct Connect connection and use AWS DMS for full load and replication

Answer

Use a VPN connection and AWS DMS for both full load and continuous replication

Answer

Use AWS DataSync over the internet to transfer data and then switch to DMS

Question 11

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 12

A company is migrating its SAP environment to AWS and wants to ensure that the migration complies with SAP's software licensing requirements. What is the most important consideration regarding SAP license mobility?

Accepted Answer

Confirm that the SAP license agreement allows running on AWS and that the target instance types are SAP certified. SAP license mobility allows customers to run their existing SAP licenses on AWS, but only if the license agreement explicitly permits it. Additionally, the target AWS instance types must be SAP certified to ensure compliance with SAP's technical requirements. Option D is correct because it addresses both contractual and technical prerequisites. Option A is incorrect because Amazon RDS does not support SAP BYOL; SAP databases on AWS use EC2. Option B is incorrect because linking AWS account to SAP's portal is not a licensing requirement. Option C is incorrect because purchasing a new license from AWS Marketplace is not necessary for license mobility.

Answer

Use SAP's Bring Your Own License (BYOL) program for Amazon RDS

Answer

Ensure that the AWS account is linked to SAP's licensing portal

Answer

Purchase a new SAP license from the AWS Marketplace

Question 13

A company is performing a large-scale migration of multiple SAP systems to AWS. They need to automate the replication of servers from on-premises to AWS while minimizing downtime. Which AWS service should they use to replicate entire servers (OS, applications, and data) in real-time?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) replicates entire servers in real-time, enabling automated migration with minimal downtime. Option B is correct. Option A (AWS CloudFormation) is for infrastructure as code, not replication. Option C (AWS DataSync) is for file storage, not full server replication. Option D (AWS Database Migration Service) is for databases only.

Answer

AWS CloudFormation

Answer

AWS DataSync

Answer

AWS Database Migration Service (DMS)

Question 14

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. To validate that the target AWS environment meets SAP HANA certification requirements, two key checks are necessary: (1) the EC2 instance type must be listed in the SAP HANA certified instance list (Option E), and (2) the operating system must be SAP certified for HANA (Option D). Option A (configuring 10 Gbps network bandwidth) is not a certification requirement; SAP HANA instances automatically use enhanced networking with adequate bandwidth. Option B (using an AMI from AWS Marketplace) is not required; you can install SAP HANA on any certified OS. Option C (ensuring EBS volumes are optimized for high throughput) is not a specific certification criterion; EBS optimization is automatically enabled on supported instance types.

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 15

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. The correct combination involves Snowball Edge for the initial large data transfer (A), DMS with ongoing change data capture (D), and SAP HANA system replication for zero-downtime cutover (E). Snowball Edge handles the initial bulk load efficiently. DMS captures ongoing changes during migration. SAP HANA system replication provides continuous data synchronization for a seamless switch. Option B (DataSync) is redundant as DMS already handles ongoing replication. Option C (SMS) is designed for server-level migration, not for SAP HANA data. Thus, A, D, and E are the three approaches to combine.

Answer

Use AWS DataSync for ongoing replication

Answer

Use AWS Server Migration Service (SMS) for server replication
