PAS-C01 Migration Practice Test 17 — 15 Questions

Question 1

A company is migrating its SAP landscape to AWS and plans to use an SAP HANA multi-node scale-out configuration. Which THREE considerations are important for the network design?

Accepted Answer

Use a placement group to ensure nodes are in close proximity. For SAP HANA multi-node scale-out on AWS, three key network considerations are: using a placement group to ensure all nodes are in close physical proximity (option A), dedicating a separate network interface for HANA inter-node traffic to maximize performance (option B), and ensuring less than 1ms RTT latency between all nodes to meet HANA's strict requirements (option E). Option C (NAT Gateway) is incorrect because NAT Gateways provide outbound internet access, not inter-node connectivity. Option D (public IP addresses) is unnecessary and insecure for inter-node communication; private IPs with placement groups and low latency are sufficient.

Answer

Use a NAT Gateway for inter-node traffic

Answer

Use public IP addresses for inter-node communication

Question 2

A company is migrating an SAP system to AWS and wants to monitor the performance of the SAP application servers. Which TWO AWS services can be used to collect and analyze SAP performance metrics?

Accepted Answer

AWS Systems Manager. Amazon CloudWatch with the SAP monitoring agent can collect SAP-specific metrics directly. AWS Systems Manager can collect OS-level metrics (CPU, memory, disk) and run custom scripts to gather SAP performance data, making it suitable for SAP performance monitoring. Option A (CloudTrail) logs API calls, not performance. Option D (Inspector) is for security scanning. Option E (X-Ray) traces application requests, not SAP performance.

Answer

AWS CloudTrail

Answer

Amazon Inspector

Answer

AWS X-Ray

Question 3

Refer to the exhibit. An administrator is creating an IAM policy for a user who will manage SAP application servers during migration. The policy currently allows starting and stopping EC2 instances. What additional permission is required to allow the user to terminate instances?

Accepted Answer

ec2:TerminateInstances. The action 'ec2:TerminateInstances' is needed to terminate instances. Option A (ec2:DeleteInstances) is not a valid action. Option C (ec2:ModifyInstanceAttribute) is unrelated. Option D (ec2:RebootInstances) is for reboot.

Answer

ec2:ModifyInstanceAttribute

Answer

ec2:RebootInstances

Answer

ec2:DeleteInstances

Question 4

Refer to the exhibit. An SAP HANA system is running on an EC2 instance with the attached volumes shown. The HANA system requires high IOPS for its data volume. Which volume should be used for the HANA data directory?

Accepted Answer

vol-1a2b3c4d5e6f78901 (io1). The io1 volume (vol-1a2b3c4d5e6f78901) provides 10,000 IOPS, which is significantly higher than the gp3 volume's 3,000 IOPS. SAP HANA data directory requires high IOPS for optimal performance, making the io1 volume the best choice. Option A (using both volumes for striping) is unnecessary and adds complexity, while Option B (gp3) has insufficient IOPS. Option C (instance store) is ephemeral and not suitable for persistent HANA data. Therefore, Option D is correct.

Answer

Both volumes for striping

Answer

vol-0a1b2c3d4e5f67890 (gp3)

Answer

Neither volume; use instance store

Question 5

Refer to the exhibit. An administrator is trying to restore an SAP HANA backup from an S3 bucket but receives an AccessDenied error. The administrator has full EC2 and S3 permissions via an IAM role attached to the EC2 instance. What is the most likely cause?

Accepted Answer

The S3 bucket has a bucket policy that denies access from the instance's IAM role. The AccessDenied error indicates an authorization failure. Since the IAM role grants full EC2 and S3 permissions, the issue is likely an explicit deny in the S3 bucket policy that overrides the IAM allow. Option A (different region) would cause a redirect error, not AccessDenied. Option B (SSE-C) would produce an encryption-related error. Option C (wrong command syntax) would result in a syntax error. Therefore, option D is correct: the bucket policy denies access from the instance's IAM role.

Answer

The S3 bucket is in a different region than the EC2 instance

Answer

The backup file is encrypted with SSE-C and the key is not provided

Answer

The administrator used the wrong S3 command syntax

Question 6

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. They want to minimize downtime and ensure data consistency. Which AWS service should be used for the migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is designed for minimal-downtime database migrations. Option B is correct. Option A (SCT) is used for schema conversion, not the migration itself. Option C (Server Migration Service) is for server-level migrations. Option D (DataSync) is for file-based data transfer.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Server Migration Service (SMS)

Answer

AWS DataSync

Question 7

A company is migrating a large-scale SAP HANA workload to AWS. The system requires high memory and low latency. Which EC2 instance type is most suitable for this migration?

Accepted Answer

x1e.32xlarge. The x1e.32xlarge is purpose-built for high-memory, SAP HANA workloads, offering up to 3,904 GiB of memory and high-speed NVMe SSD storage with low-latency networking. It is certified by SAP for running production HANA environments, making it the most suitable choice for this migration.

Answer

m5.24xlarge

Answer

c5.18xlarge

Answer

r5.24xlarge

Question 8

A company is migrating its SAP ERP system to AWS using the SAP S/4HANA migration approach. They need to replicate the source system continuously to the target before cutover. Which AWS service should be used for this continuous replication?

Accepted Answer

AWS CloudEndure Migration. AWS CloudEndure Migration provides continuous block-level replication from on-premises servers to AWS, making it suitable for SAP S/4HANA migrations requiring ongoing replication before cutover. AWS SCT (A) is for schema conversion, not replication. AWS SMS (B) migrates entire servers but does not support continuous replication. AWS DMS (C) can replicate databases but has limitations for SAP-specific workloads and is not the recommended service for SAP S/4HANA continuous replication. Therefore, AWS CloudEndure (D) is the correct choice.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (DMS)

Question 9

A company is migrating its SAP systems to AWS and needs to ensure high availability for the SAP Central Services (ASCS) instance. Which AWS service can be used to implement a failover cluster for ASCS?

Accepted Answer

AWS using shared file system and DNS-based failover. For SAP ASCS failover, AWS recommends using a shared file system (e.g., Amazon EFS) combined with DNS-based failover via Route53. This provides high availability without requiring additional clustering software. Option C correctly describes this approach. Option A (Amazon S3) is object storage, not suitable for ASCS. Option B (Application Load Balancer) handles inbound traffic, not ASCS clustering. Option D (Amazon RDS Multi-AZ) is for database high availability, not ASCS.

Answer

Amazon S3

Answer

Application Load Balancer (ALB)

Answer

Amazon RDS Multi-AZ

Question 10

A company is migrating its SAP landscape to AWS and wants to use SAP HSR (System Replication) for high availability. Which AWS feature is required to support SAP HSR?

Accepted Answer

Both instances in the same VPC with private IP connectivity. SAP HSR (System Replication) requires low-latency, reliable connectivity between the primary and secondary instances to synchronize data in real-time. Placing both instances in the same VPC enables them to communicate using private IP addresses, which are internal to the VPC and typically have lower latency and higher throughput compared to public IPs. This setup is essential for meeting the RPO and RTO requirements of SAP HSR. Options A (Elastic IP), B (Internet Gateway), and D (NAT Gateway) are not necessary for HSR and may introduce additional complexity or security risks.

Answer

Elastic IP addresses for each instance

Answer

Internet Gateway attached to the VPC

Answer

NAT Gateway for outbound traffic

Question 11

During a migration of an SAP ERP system to AWS, the team notices that the SAP application performance is slow on the new EC2 instances. The instance type is correct for SAP certification. What is the most likely cause?

Accepted Answer

EBS volumes are not provisioned with enough IOPS. Storage performance, specifically IOPS, often impacts SAP performance. Even if the instance type is correct, if the EBS volumes are not provisioned with sufficient IOPS, performance will suffer. Option D is correct. Option A (incorrect instance type) is not the issue. Option B (placement group) could be an issue but is less likely. Option C (security group) wouldn't cause performance issues.

Answer

Instances are in different placement groups

Answer

Incorrect EC2 instance type

Answer

Security group rules are blocking traffic

Question 12

Amazon QuickSight. Amazon QuickSight is a fully managed business analytics service that can replace SAP BusinessObjects for reporting and dashboards, reducing operational overhead. Option A (QuickSight) is correct. Option B (EMR) is for big data processing. Option C (Redshift) is a data warehouse. Option D (RDS) is a relational database service.

Answer

Amazon EMR

Answer

Amazon Redshift

Answer

Amazon RDS

Question 13

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?

Accepted Answer

Use EC2 instance types listed in the SAP Certified and Supported SAP HANA Hardware Directory. To maintain SAP license compliance, the company must use EC2 instance types that are listed in the SAP Certified and Supported SAP HANA Hardware Directory. This directory provides the list of AWS instance types that are officially certified for SAP and have the appropriate licensing support. Option D is correct. Option A (AWS License Manager) can enforce license limits but does not verify if the instance types are SAP-certified. Option B (BYOL) is a licensing model, not a verification method. Option C (AWS Config) can track instance configurations but does not verify SAP certification or licensing.

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 14

A company is migrating its SAP ERP system to AWS using a heterogeneous migration where the source database is Oracle and the target is SAP HANA. Which AWS service is essential for converting the Oracle schema to SAP HANA schema?

Accepted Answer

AWS Schema Conversion Tool (SCT). AWS Schema Conversion Tool (SCT) is designed to convert database schemas from one engine to another, including Oracle to SAP HANA. Option C is the correct choice. Option A (AWS DMS) migrates data but does not convert schema. Option B (AWS DataSync) is for file transfer. Option D (AWS SMS) is for server migration.

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Answer

AWS Server Migration Service (SMS)

Question 15
