PAS-C01 Practice Test 28 — 15 Questions

Question 1

A company is migrating a 3 TB SAP ERP system running on Oracle on AIX to SAP HANA on AWS. The system has a complex landscape with multiple application servers and a central Oracle database. The migration must be completed within a 4-day window with minimal downtime. The company has a 1 Gbps AWS Direct Connect connection. The SAP system is heavily customized with many ABAP programs and custom database objects. The migration team plans to use SAP Software Update Manager (SUM) with the Database Migration Option (DMO). During the migration rehearsal, the SUM DMO process fails during the database migration phase with an error indicating that the source database character set is not supported by the target SAP HANA. The source Oracle database uses the WE8ISO8859P1 character set. The team needs to resolve this issue before the final migration. Which course of action should the team take?

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

Accepted Answer

Convert the source Oracle database character set to UTF-8 (AL32UTF8) before starting the SUM DMO migration.. SAP HANA only supports UTF-8 character encoding. Therefore, the source Oracle database must be converted to UTF-8 (AL32UTF8) before using SUM DMO. Option A is incorrect because SAP HANA Studio migration tools cannot convert an unsupported character set during migration; they also require the source data to be UTF-8. Option B is incorrect because AWS Database Migration Service (AWS DMS) does not support SAP HANA as a target for SAP system migrations and cannot handle the necessary SAP-specific objects and customizations. Option D is incorrect because you cannot modify SAP HANA database parameters to support WE8ISO8859P1; HANA only works with UTF-8.

Answer

Use SAP HANA Studio migration tools to convert the character set during migration without changing the source.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the data and automatically convert the character set.

Answer

Change the target SAP HANA database to use the WE8ISO8859P1 character set by modifying the HANA database parameters.

Question 2

An operations team receives an alert that an SAP application server EC2 instance is unreachable. The team checks the AWS Management Console and sees that the instance status check shows "Instance reachability check failed". What is the most likely cause?

Accepted Answer

The operating system on the instance is not responding.. An EC2 status check of 'Instance reachability check failed' specifically indicates that the instance's operating system is not responding to the hypervisor's network and CPU checks. This is distinct from a system status check failure (which indicates AWS infrastructure issues). The most likely cause is that the OS is hung, crashed, or otherwise unresponsive.

Answer

The security group associated with the instance is blocking all traffic.

Answer

The EBS root volume is detached from the instance.

Answer

The instance was stopped by an Auto Scaling group.

Question 3

A company is migrating a multi-tier application to AWS. The application includes a load balancer, web servers, and an Oracle database. The migration plan includes using AWS DMS for the database. During the initial full load, the DMS task fails with an error indicating insufficient memory. The source database is on an EC2 instance with 4 GB RAM. What should the migration team do to resolve this issue?

Accepted Answer

Increase the size of the DMS replication instance. The error 'insufficient memory' during the initial full load in AWS DMS typically indicates that the replication instance does not have enough memory to handle the data volume or LOB processing. Increasing the size of the DMS replication instance provides more memory for caching, transformation, and LOB handling, directly resolving the resource constraint without altering the source database or task structure.

Answer

Disable LOB support in the DMS task

Answer

Split the migration into multiple smaller tasks

Answer

Increase the memory of the source EC2 instance

Question 4

An SAP administrator needs to ensure that the SAP landscape on AWS is compliant with the SAP license requirements. What is the responsibility of the customer regarding SAP licensing on AWS?

Accepted Answer

The customer must bring their own SAP licenses and ensure compliance with SAP licensing terms. AWS operates under a bring-your-own-license (BYOL) model for SAP software. The customer is responsible for procuring SAP licenses, ensuring they are valid for the AWS environment, and complying with SAP's licensing terms, including any restrictions on virtualization, CPU cores, and memory. AWS provides the infrastructure, but not the SAP licenses themselves.

Answer

AWS provides SAP licenses as part of the EC2 instance pricing

Answer

SAP licensing is automatically handled by AWS Support

Answer

SAP licenses are included when using SAP HANA on AWS

Question 5

A DevOps engineer needs to automatically restart a specific service on an EC2 instance whenever the service crashes. The instance is running Amazon Linux 2. Which approach is the MOST operationally efficient?

Accepted Answer

Configure the service as a systemd unit with Restart=on-failure. Systemd, the default init system on Amazon Linux 2, provides a built-in `Restart=` directive that can be set to `on-failure`. This instructs systemd to automatically restart the service unit when it exits with a non-zero exit code or is terminated by a signal, without requiring any external monitoring or additional infrastructure. This is the most operationally efficient approach as it leverages the native service manager functionality with zero external dependencies.

Answer

Set up a CloudWatch alarm that triggers an SSM Run Command to restart the service

Answer

Write a cron job that checks the service status every minute and restarts it if needed

Answer

Use an AWS Lambda function that polls the service status and calls the EC2 reboot API

Question 6

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. With 100 TB of data over a low-bandwidth cross-country link, transferring over the network is impractical — even at 1 Gbps sustained, 100 TB takes roughly 10 days of perfect throughput. AWS Snowball Edge is purpose-built for offline bulk transfer at petabyte scale, and AWS DMS can then handle ongoing change data capture (CDC) replication from SAP HANA to the AWS target once the initial load is seeded. This hybrid approach minimizes cutover downtime while avoiding the bandwidth bottleneck.

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 7

An SAP administrator needs to review API calls made by a user who accidentally deleted an S3 bucket used for SAP backups. Which AWS service provides a record of these API calls?

Accepted Answer

AWS CloudTrail. AWS CloudTrail is the correct service because it records all API calls made to the AWS environment, including S3 bucket deletion events. When a user accidentally deletes an S3 bucket, CloudTrail captures the event details such as the user identity, source IP, and timestamp, enabling the SAP administrator to audit the action. This is essential for security analysis and operational troubleshooting in the context of SAP backups.

Answer

Amazon S3 server access logs

Answer

Amazon CloudWatch Logs

Answer

AWS Config

Question 8

A company is using SAP S/4HANA on AWS and wants to optimize costs. Which THREE actions would help reduce costs without impacting performance? (Choose THREE.)

Accepted Answer

Implement automatic start/stop for development and test instances. Option A is correct because scheduling automatic start/stop of non-production development and test instances via AWS Instance Scheduler or EventBridge/Lambda eliminates charges for idle compute hours without affecting production performance. Option B is correct because AWS Compute Optimizer analyzes CloudWatch metrics and recommends optimal EC2 instance types, allowing right-sizing that reduces cost while maintaining the required performance for SAP S/4HANA workloads. Option E is correct because purchasing Reserved Instances for the steady-state production database server provides significant discounts (up to 72% versus On-Demand) for a predictable, always-on workload without any performance impact. Option C is not correct because Dedicated Hosts typically increase cost and are used for licensing or compliance isolation, not cost optimization. Option D is not correct because replacing io2 Block Express with gp2 would reduce IOPS and latency performance for SAP S/4HANA, which is performance-impacting and not a valid cost optimization here.

Answer

Use Dedicated Hosts for better isolation

Answer

Replace io2 Block Express volumes with gp2 volumes

Question 9

Which THREE factors should be considered when choosing an instance type for an SAP HANA database on AWS? (Select THREE.)

Accepted Answer

Memory size of the instance. Options A, B, and E are correct. Memory size (A) is critical because SAP HANA is an in-memory database. The instance must be certified for SAP HANA (B) to ensure compatibility and support. Network throughput (E) is important for data replication and client access. Option C is incorrect because the number of attachable EBS volumes is not a primary selection criterion for SAP HANA. Option D is incorrect because GPU capabilities are not required for SAP HANA.

Answer

Number of EBS volumes that can be attached

Answer

GPU capabilities of the instance

Question 10

A company runs SAP ERP on AWS with a DR strategy using cross-region replication for SAP HANA. During a DR drill, the team discovers that the HANA database is not starting on the DR instance. Which configuration is most likely missing?

Accepted Answer

HANA system replication configuration with the correct 'PRIMARY' and 'SECONDARY' roles.. HANA system replication configuration with the correct PRIMARY and SECONDARY roles is most likely missing because the DR instance must be configured as a secondary site in the HANA system replication setup. Without proper configuration, the HANA database on the DR instance cannot start or take over. This is a critical configuration for cross-region replication and DR failover.

Answer

IAM roles for the DR instance to access S3.

Answer

EBS encryption on the DR volumes.

Answer

CloudWatch agent for logging.

Question 11

Which THREE are valid steps when performing a cross-Region disaster recovery failover for SAP HANA using AWS? (Choose THREE.)

Accepted Answer

Start the SAP HANA database on the secondary instance. Option B is correct because after the replicated data is available and the primary is unavailable, the SAP HANA database must be started (or taken over) on the secondary instance in the DR Region to resume service. Option D is correct because cross-Region disaster recovery for SAP HANA relies on SAP HANA System Replication (HSR) configured between the primary and secondary Regions so that data is continuously replicated to the DR site. Option E is correct because clients and applications must be redirected to the secondary instance, typically by updating DNS records (e.g., a CNAME or Route 53 record) to point to the DR endpoint. Option A is not a required failover step; EBS snapshots are a backup mechanism, not the cross-Region replication method used for HSR-based DR failover. Option C is not required for failover and may not even be possible if the primary Region has failed; stopping the primary database is not a prerequisite for bringing up the secondary.

Answer

Create an EBS snapshot of the primary database volume

Answer

Stop the SAP HANA database on the primary instance

Question 12

A company is migrating an SAP system to AWS. They want to use AWS Launch Wizard to deploy SAP. Which TWO prerequisites are required for using Launch Wizard? (Choose TWO.)

Accepted Answer

An EC2 key pair for SSH access to the SAP instances. Option A is correct because AWS Launch Wizard requires an existing EC2 key pair so it can associate it with the launched SAP instances and allow SSH access for administration and troubleshooting. Option C is correct because Launch Wizard needs an IAM role (or user credentials) with the appropriate permissions to create and manage the underlying AWS resources such as EC2 instances, EBS volumes, security groups, and CloudFormation stacks on your behalf. Option B is not required because Direct Connect is only a connectivity choice for hybrid scenarios, not a Launch Wizard prerequisite. Option D is not required because Launch Wizard does not mandate an AWS Organization with all features enabled. Option E is not required because SAP software can be brought via your own media/license or Marketplace, but a Marketplace subscription is not a mandatory prerequisite for using Launch Wizard.

Answer

AWS Direct Connect connection to on-premises

Answer

An AWS Organization with all features enabled

Answer

A subscription to SAP software in AWS Marketplace

Question 13

A company is migrating its SAP system to AWS. The system uses a custom ABAP program that writes to a local file system. Which TWO AWS services can the company use to provide a shared file system accessible to multiple EC2 instances?

Accepted Answer

Amazon FSx for Lustre. Amazon FSx for Lustre (A) is correct because it is a fully managed, high-performance parallel file system that can be mounted simultaneously by multiple EC2 instances, making it suitable for shared file access in workloads like SAP custom ABAP programs. Amazon EFS (D) is also correct because it is a managed NFS file system designed for shared, concurrent access from many EC2 instances across Availability Zones, which satisfies the requirement for a shared local-like file system. Amazon RDS (B) is a managed relational database service, not a file system, so it cannot provide shared file storage. Amazon S3 (C) is object storage and is not natively mountable as a POSIX shared file system for multiple EC2 instances without additional gateway or caching layers. Amazon EBS (E) provides block storage volumes that are typically attached to a single EC2 instance at a time and do not natively offer a shared file system across multiple instances.

Answer

Amazon RDS

Answer

Amazon S3

Answer

Amazon EBS

Question 14

A company is migrating an SAP BusinessObjects environment to AWS. They need to ensure high availability for the web tier and have a requirement to use a single DNS name for end users. Which AWS service should they use to distribute traffic across multiple web servers?

Accepted Answer

Application Load Balancer. Application Load Balancer (ALB) operates at Layer 7 and can distribute HTTP/HTTPS traffic across multiple web servers, providing health checks and a single DNS name. Option A (Amazon CloudFront) is a content delivery network, not a load balancer. Option B (Network Load Balancer) operates at Layer 4 and is ideal for TCP/UDP traffic, not web application traffic. Option C (Amazon Route 53 weighted routing policy) distributes traffic based on weights but does not provide built-in health checks or load balancing features like connection draining and path-based routing.

Answer

Amazon CloudFront

Answer

Network Load Balancer

Answer

Amazon Route 53 weighted routing policy

Question 15

A company is running SAP ERP on AWS and needs to encrypt data at rest for all SAP-related storage. Which combination of AWS services can be used to achieve this? (Select TWO.)

Accepted Answer

Amazon S3 server-side encryption. Amazon EBS encryption (Option D) provides at-rest encryption for the block storage volumes used by SAP EC2 instances, ensuring data on the underlying disks is encrypted. Amazon S3 server-side encryption (Option B) encrypts data at rest in S3 buckets, which can be used for SAP backups, log archives, or other SAP-related object storage. Together, they cover the primary storage types for SAP on AWS.

Answer

AWS Identity and Access Management (IAM)

Answer

AWS WAF

Answer

Amazon CloudWatch Logs
