PAS-C01 Migration Practice Test 11 — 15 Questions

Question 1

A company is migrating an SAP system to AWS and wants to use AWS Launch Wizard for deployment. They have an existing VPC and subnets. Launch Wizard requires the selection of a subnet for each component. What is the best practice for selecting subnets for high availability?

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

Accepted Answer

Select subnets in different Availability Zones to ensure high availability.. For high availability, it is best to deploy SAP components across multiple Availability Zones by selecting subnets in different AZs. Launch Wizard supports this. Deploying all in one AZ creates a single point of failure. Launch Wizard can use existing subnets.

Answer

Use only private subnets without public access.

Answer

Select a single subnet in one Availability Zone for simplicity.

Answer

Create a new VPC and subnets specifically for Launch Wizard.

Question 2

During the migration of an SAP NetWeaver system, the team notices that the application server performance is degraded after migrating to AWS. The system uses AWS EBS volumes for storage. Which of the following is the most likely cause of the performance degradation?

Accepted Answer

The EBS volumes have insufficient provisioned IOPS for the workload.. If EBS volumes are not provisioned with sufficient IOPS, the application server may experience performance degradation. EBS-optimized instances and appropriate volume types are important. EBS volumes are typically designed for durability, and encryption does not cause performance degradation.

Answer

The EBS volumes are using the wrong volume type.

Answer

The EBS volumes are not encrypted.

Answer

The EBS volumes are not EBS-optimized.

Question 3

A company is migrating a large SAP Business Warehouse (BW) system to AWS. The system uses SAP HANA as the database. The migration plan involves using SAP HANA System Replication (HSR) for near-zero downtime. During the initial synchronization, the network bandwidth is limited to 1 Gbps. The source database is 5 TB. How long will the initial synchronization approximately take, assuming no other bottlenecks?

Accepted Answer

Approximately 12 hours. 5 TB = 5,000 GB = 40,000 Gb (since 1 GB = 8 Gb). At 1 Gbps, time = 40,000 seconds ≈ 11.1 hours. This simple calculation ignores overhead, but among the options, 12 hours is the closest. The other options are unrealistic.

Answer

Approximately 2 hours

Answer

Approximately 6 hours

Answer

Approximately 24 hours

Question 4

A company is migrating an SAP system to AWS using the SAP DMO (Database Migration Option) with system move. Which TWO prerequisites must be met before starting the migration?

Accepted Answer

The target EC2 instances and storage must be prepared in advance.. SAP DMO requires that the source system is on a supported SAP NetWeaver release and that the target AWS infrastructure (EC2, storage) is prepared. The source database does not need to be stopped; DMO can run online. A separate AWS account is not a prerequisite. A direct network connection is recommended but not strictly required.

Answer

A separate AWS account must be used for the target system.

Answer

The source database must be stopped during the entire migration.

Answer

A VPN or Direct Connect connection must be established.

Question 5

Which THREE considerations are important when planning the migration of an SAP HANA database to AWS using HANA System Replication (HSR)?

Accepted Answer

The target EC2 instance must have at least the same amount of RAM as the source.. HSR requires network latency below 10 ms for synchronous replication, and the target instance must have sufficient memory and storage. Network bandwidth is important but not the only factor. The source and target can be in different Regions, but latency must be acceptable. Encryption is not a prerequisite for HSR.

Answer

The source and target must be in the same AWS Region.

Answer

The source database must be encrypted before replication can start.

Question 6

A company is migrating an SAP system to AWS using the SAP Landscape Reorganization (LaMa) tool. Which TWO actions can LaMa perform during the migration?

Accepted Answer

Migrate SAP systems from on-premises to AWS with minimal downtime.. LaMa is designed to orchestrate system migrations with minimal downtime by automating the cloning and replication process. It uses storage-level snapshots or database replication to keep the source system running until the final cutover, which is why Option B is correct.

Answer

Perform a heterogeneous system copy.

Answer

Convert the source database from Oracle to SAP HANA.

Answer

Automatically update DNS records after migration.

Question 7

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database is 2 TB and has a 4-hour maintenance window. Which AWS service should be used to minimize downtime during the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports ongoing replication with minimal downtime by using change data capture (CDC) to synchronize source and target databases continuously. Option B, AWS Server Migration Service (SMS), is designed for migrating entire server volumes, not databases. Option C, AWS Application Migration Service (MGN), automates server migration but is not optimized for database replication. Option D, AWS DataSync, is for transferring large file sets to or from AWS storage services, not for live database replication.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Application Migration Service (MGN)

Answer

Question 9

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?

Accepted Answer

Amazon Route 53. Amazon Route 53 with failover routing policy and health checks can automate DNS-level failover by directing traffic to the healthy SAP HANA instance. Combined with SAP HANA System Replication across AZs, this provides automated database failover. Option B (AWS CloudFormation) provisions infrastructure but does not automate failover. Option C (AWS Elastic Disaster Recovery) is designed for cross-region disaster recovery, not cross-AZ high availability. Option D (AWS Backup) handles scheduled backups, not real-time failover.

Answer

AWS CloudFormation

Answer

AWS Elastic Disaster Recovery (DRS)

Answer

AWS Backup

Question 10

A company is migrating a web application to AWS and wants to minimize latency for global users. Which AWS service should be used to cache static content at edge locations?

Question 15

A company is migrating a critical SAP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). Which AWS service can be used to manage the virtual IP address required for the SAP high availability setup?

Accepted Answer

Elastic Load Balancer (ELB). For SAP high availability on AWS, the virtual IP (VIP) for ASCS/ERS is typically managed using a Network Load Balancer (NLB), which provides a static IP address that can be used as the VIP. NLB supports health checks and automatic failover between active and passive instances. Amazon Route 53 Application Recovery Controller is designed for multi-region recovery and DNS-level failover, not for managing a VIP within a single region. AWS Transit Gateway handles network connectivity between VPCs, and AWS Global Accelerator provides static IPs for global traffic optimization, not for SAP HA VIP management.
