PAS-C01 Design of SAP Workloads on AWS Practice Test 3 — 15 Questions

Question 1

Match the SAP system component to its AWS service or concept.

Question 2

Match the SAP sizing parameter to its AWS EC2 equivalent.

Question 3

Match the SAP system type to its typical AWS deployment pattern.

Question 4

A company is designing an SAP S/4HANA workload on AWS. The system must be highly available within a single AWS Region. Which architecture ensures automatic failover for the SAP Central Services (ASCS) instance?

Accepted Answer

Configure Amazon Route 53 with health checks to failover to a secondary ASCS instance in a different Availability Zone.. Option D is correct because Amazon Route 53 with health checks can monitor the primary ASCS instance and automatically fail over DNS resolution to a secondary ASCS instance in a different Availability Zone. This provides the necessary automatic failover for SAP Central Services (ASCS) without requiring a shared filesystem or cluster manager, as Route 53 health checks detect instance or service failure and update DNS records accordingly.

Answer

Place an Application Load Balancer (ALB) in front of two ASCS instances in different Availability Zones.

Answer

Deploy ASCS on a single EC2 instance with multiple Elastic Network Interfaces (ENIs).

Answer

Use Amazon CloudFront to distribute traffic to multiple ASCS instances in different Availability Zones.

Question 5

An SAP Basis team is migrating an SAP Business Suite system to AWS. The system has a large number of background jobs and requires consistent performance for batch processing. Which Amazon EC2 instance type is most suitable for this workload?

Accepted Answer

z1d.xlarge. The z1d.xlarge instance is most suitable because it offers a high baseline clock speed of up to 4.0 GHz with Intel Turbo Boost, which is critical for SAP Business Suite batch processing workloads that are CPU-bound and sensitive to single-threaded performance. SAP background jobs often require consistent, high-frequency CPU performance to meet batch window SLAs, and the z1d family is specifically designed for such high-performance, memory-intensive SAP workloads on AWS.

Answer

i3.2xlarge

Answer

g4dn.xlarge

Answer

t3.large

Question 6

A company is designing storage for an SAP HANA database on AWS. The database requires high throughput and low latency for data files. Which storage solution should be used for SAP HANA data volumes?

Accepted Answer

Amazon EBS gp3 or io2 volumes. Amazon EBS gp3 or io2 volumes are the correct choice for SAP HANA data volumes because they provide the high throughput, low latency, and consistent IOPS required for SAP HANA's in-memory database operations. gp3 offers baseline performance with the ability to scale independently, while io2 provides provisioned IOPS for critical workloads, both meeting SAP's certification requirements for HANA on AWS.

Answer

Amazon S3

Answer

EC2 Instance Store

Answer

Amazon EFS

Question 7

A company runs SAP HANA on AWS and needs to restore a database from a backup stored in Amazon S3. The backup was created using the SAP HANA backup to S3 feature (backint). Which AWS service is required to facilitate this restore?

Accepted Answer

AWS Backup. AWS Backup is the correct service because it natively integrates with SAP HANA's backint interface to manage backups stored in Amazon S3. When a backup is created using the SAP HANA backup to S3 feature (backint), AWS Backup provides the necessary orchestration and lifecycle management to restore the database from those S3 objects, including handling the metadata and catalog required for SAP HANA to recognize and apply the backup.

Question 8

An SAP system on AWS is experiencing high latency for disk I/O. The system uses Amazon EBS gp2 volumes. The operations team notices that the volume queue depth is consistently high. Which change is most likely to reduce latency?

Accepted Answer

Migrate from gp2 to gp3 volumes and increase IOPS.. The correct answer is B because gp3 volumes offer a baseline performance that is higher than gp2 for a given size, and they allow you to independently increase IOPS without needing to provision more storage. Since the volume queue depth is consistently high, the bottleneck is likely due to insufficient IOPS, and migrating to gp3 with increased IOPS directly addresses this by providing more I/O capacity, reducing latency.

Answer

Increase the EC2 instance size to get more EBS bandwidth.

Answer

Configure RAID 0 across multiple EBS volumes.

Answer

Increase the block size of the file system.

Question 9

A company is planning to run SAP NetWeaver on AWS and needs to ensure high availability for the database layer. Which AWS service can be used to achieve automatic failover of an SAP HANA database?

Accepted Answer

SAP HANA System Replication (HSR). SAP HANA System Replication (HSR) is the native SAP mechanism for replicating data from a primary HANA database to one or more secondary systems, enabling automatic failover in the event of a primary failure. This is the correct approach for achieving high availability for SAP HANA on AWS, as it integrates with AWS services like Elastic IPs or Route53 for IP re-mapping during failover, and is fully supported by SAP for production workloads.

Answer

AWS Database Migration Service (DMS)

Answer

Application Load Balancer (ALB)

Answer

Amazon RDS Multi-AZ

Question 10

A company is deploying SAP Business Suite on AWS and wants to minimize network latency between the SAP application servers and the database server. Which placement strategy is best?

Accepted Answer

Place the servers in the same placement group within a single Availability Zone.. Placement groups in AWS allow you to influence the placement of a group of interdependent instances to meet the needs of your workload. For SAP Business Suite, which is sensitive to network latency between application and database servers, using a cluster placement group within a single Availability Zone ensures the lowest possible latency and maximum throughput, as instances are placed in close proximity to each other, often within the same rack, enabling high-bandwidth, low-latency networking.

Answer

Place the servers in different VPCs connected via VPC Peering.

Answer

Place the application and database servers in different Availability Zones within the same region.

Answer

Place the servers in different AWS Regions.

Question 11

An SAP HANA database on AWS is using EBS gp3 volumes with 3000 IOPS. The database team observes that the write latency is high during peak hours. The EBS volume is not exceeding its bandwidth limit. What is the most likely cause?

Accepted Answer

The EBS volume's IOPS limit is being reached, causing queuing.. The correct answer is B because the observed high write latency during peak hours, despite the EBS volume not exceeding its bandwidth limit, indicates that the volume's IOPS limit of 3000 is being reached. When the IOPS limit is hit, the EBS volume queues I/O requests, which increases latency. This is a classic symptom of IOPS saturation rather than bandwidth saturation.

Answer

The EBS volume is not attached as a dedicated EBS bandwidth volume.

Answer

The EC2 instance's EBS bandwidth is saturated.

Answer

The EC2 instance does not have EBS optimization enabled.

Question 12

A company wants to automate the installation of SAP software on AWS. Which AWS service is most appropriate for orchestrating the deployment of SAP systems?

Accepted Answer

AWS CloudFormation. AWS CloudFormation is the most appropriate service for orchestrating the deployment of SAP systems because it allows you to define the entire infrastructure as code using templates, enabling automated, repeatable, and consistent provisioning of SAP landscapes. It supports custom resources and nested stacks, which are essential for managing the complex dependencies and multi-tier architecture typical of SAP deployments on AWS.

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Answer

AWS Lambda

Question 13

Which TWO of the following are best practices for running SAP HANA on AWS? (Select TWO.)

Accepted Answer

Use EBS Snapshots for backup of HANA data volumes.. Option D is correct because EBS Snapshots provide a consistent, crash-consistent backup mechanism for HANA data volumes when used with application-consistent procedures (e.g., pre-freeze/post-thaw scripts via AWS Backup or custom automation). Snapshots are block-level, incremental, and can be automated for point-in-time recovery, aligning with SAP HANA backup best practices on AWS.

Answer

Use Amazon EFS as the storage layer for HANA data files.

Answer

Use T3 instances for production to save costs.

Answer

Use Amazon RDS Multi-AZ for HANA database replication.

Question 14

Which THREE of the following are valid strategies for disaster recovery (DR) of SAP workloads on AWS? (Select THREE.)

Accepted Answer

Pilot light environment with replicated data volumes that can be attached to EC2 instances in DR.. Option B is correct because a pilot light DR strategy for SAP on AWS involves replicating data volumes (e.g., using EBS snapshots or storage replication) to a secondary region and keeping a minimal set of core services running. In a disaster, EC2 instances are launched and the replicated volumes are attached, allowing the SAP application stack to be started quickly. This approach balances cost and recovery time by avoiding a fully scaled environment during normal operations.

Answer

Warm standby with a fully scaled-down environment that is manually scaled up during DR.

Answer

Multi-site active-active with real-time replication and automatic failover.

Question 15

Which TWO of the following are required for SAP HANA high availability on AWS using HANA System Replication (HSR) with automatic failover? (Select TWO.)

Accepted Answer

An Amazon Route 53 health check that monitors the primary instance and updates a DNS record to the secondary IP on failure.. Option B is correct because Amazon Route 53 health checks can monitor the primary HANA instance's availability. On failure, a Route 53 failover routing policy automatically updates the DNS record to point to the secondary instance's private IP, enabling clients to reconnect without manual intervention. This is a key component of HANA System Replication (HSR) with automatic failover on AWS.

Answer

Application Auto Scaling to automatically scale HANA instances.

Answer

An Elastic Load Balancer (ELB) in front of the HANA instances to distribute traffic.

Answer

An Amazon Route 53 alias record pointing to the primary instance's private IP.
