PAS-C01 Design of SAP Workloads on AWS Practice Test 21 — 15 Questions

Question 1

A company is running an SAP NetWeaver application server on AWS. The application server is deployed on an EC2 instance with a single EBS volume for the operating system and SAP binaries. The company wants to improve the performance of the application server and ensure that it can handle a sudden increase in user load. Which action should be taken?

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

Accepted Answer

Deploy the application server in an Auto Scaling group behind an Application Load Balancer and use a shared file system for SAP binaries.. To handle variable user loads, the SAP NetWeaver application server tier should be horizontally scalable. Deploying in an Auto Scaling group with an Application Load Balancer and a shared file system for SAP binaries allows instances to be added or removed based on demand, improving performance and availability.

Answer

Change the EBS volume to a Provisioned IOPS SSD (io2) volume and enable EBS optimization on the EC2 instance.

Answer

Use AWS Global Accelerator to distribute traffic to the application server.

Answer

Increase the size of the EBS volume and enable detailed monitoring in Amazon CloudWatch.

Question 2

A company is planning to migrate its SAP HANA database to AWS. The database is currently 2 TB in size and is expected to grow to 4 TB within two years. The company wants to minimize cost while ensuring that the database can be backed up and restored quickly. Which storage solution should be used for the SAP HANA database?

Accepted Answer

Amazon EBS io2 Block Express volumes with 64,000 IOPS and 1,000 MiB/s throughput.. SAP HANA requires high-performance block storage with low latency and high IOPS. EBS io2 Block Express volumes are specifically designed for such workloads and are certified for SAP HANA on AWS. They offer the necessary performance and can scale as the database grows. Other options either do not meet performance requirements (gp3, st1) or are not suitable for database storage (EFS).

Answer

Amazon EBS gp3 volumes with 16,000 IOPS and 1,000 MiB/s throughput.

Answer

Amazon EBS st1 volumes with 40,000 IOPS and 500 MiB/s throughput.

Answer

Amazon EFS with Provisioned Throughput of 1,000 MiB/s.

Question 3

A company is designing the storage layout for a new SAP HANA database on AWS. The database will use multiple EBS volumes for data and log. Which TWO configurations are recommended for optimal performance and reliability? (Choose two.)

Accepted Answer

Use Provisioned IOPS SSD (io1 or io2) EBS volumes for data and log volumes.. For SAP HANA on AWS, using Provisioned IOPS SSD volumes ensures dedicated, consistent performance, and enabling EBS encryption secures data at rest with negligible overhead. These two practices are recommended for optimal performance and reliability. Other options either degrade performance or violate SAP HANA storage best practices.

Answer

Use Throughput Optimized HDD (st1) volumes for the log volume to reduce cost.

Answer

Place data and log volumes on the same EBS volume to simplify management.

Answer

Configure the data volume with a single large EBS volume instead of multiple smaller volumes.

Question 4

A company is designing the network architecture for a new SAP S/4HANA system on AWS. The system will consist of an SAP HANA database on an EC2 instance and multiple SAP application servers on separate EC2 instances. The company requires high availability and wants to minimize latency between the database and application servers. The company also wants to ensure that the SAP system can communicate with on-premises systems securely. Which TWO design choices should be implemented? (Choose two.)

Accepted Answer

Use AWS Transit Gateway to connect the VPC to the on-premises network over a VPN or Direct Connect.. To minimize latency and ensure secure hybrid connectivity, deploy the HANA database and application servers in the same Availability Zone within a single VPC, and use AWS Transit Gateway to connect the VPC to on-premises over VPN or Direct Connect. This combination provides low latency for SAP traffic and a scalable, secure connection to on-premises systems. Other options either introduce unnecessary complexity, lack high availability, or compromise security.

Answer

Use an AWS Site-to-Site VPN with a single tunnel for all communication between AWS and on-premises.

Answer

Place the HANA database in a private subnet and the application servers in a public subnet to allow internet access.

Answer

Deploy the HANA database and application servers in separate VPCs peered together using VPC peering.

Question 5

A company is migrating an SAP Business Suite system on Oracle Database to AWS. The database is currently 2 TB and experiences heavy write-intensive OLTP workload. They need to choose an Amazon EBS volume type for the Oracle data files that provides consistent IOPS and low latency at the lowest cost. Which EBS volume type should be used?

Accepted Answer

io1 with 32,000 IOPS and 500 MiB/s throughput. For write-intensive OLTP Oracle databases on AWS, provisioned IOPS volumes like io1 offer consistent low latency and high IOPS at a lower cost than io2 Block Express. gp3 may not provide sufficient consistent performance, and st1 is unsuitable for random I/O. Therefore, io1 with 32,000 IOPS is the best balance of performance and cost.

Answer

io2 Block Express with 64,000 IOPS and 1,000 MiB/s throughput

Answer

st1 with 500 MiB/s throughput

Answer

gp3 with 16,000 IOPS and 1,000 MiB/s throughput

Question 6

A company is deploying a new SAP NetWeaver ABAP system on AWS. The SAP application servers will run on Amazon EC2 instances in a private subnet, and the SAP HANA database will run on a separate EC2 instance in another private subnet. The company requires that the application servers access the database using a stable, private IP address that does not change if the database instance is stopped and started. The database instance will not be replaced. Which AWS resource should be used to provide this stable private IP address?

Accepted Answer

Create a secondary private IP address on the SAP HANA database instance's primary elastic network interface (ENI) and use that address in the SAP application server's configuration.. Assigning a secondary private IP address to the database instance's ENI ensures that the SAP application servers can always reach the database at the same private IP, even after a stop/start cycle. The ENI and its secondary IPs persist independently of the instance lifecycle. This is the standard AWS approach for providing a stable private endpoint for SAP HANA without introducing load balancers or public addresses.

Answer

Configure an Application Load Balancer in front of the SAP HANA database instance and use the load balancer's DNS name.

Answer

Create a Network Load Balancer with the SAP HANA database instance as a target and use the load balancer's private IP address.

Answer

Assign an Elastic IP address to the SAP HANA database instance.

Question 7

A company is deploying SAP NetWeaver ABAP application servers on AWS. The SAP application servers must be highly available and able to fail over automatically within the same Availability Zone without manual intervention. The company uses an Application Load Balancer (ALB) for HTTP traffic and wants to ensure that SAP GUI sessions and enqueue replication are not disrupted during a failover. Which design should a SAP specialist implement?

Accepted Answer

Configure an AWS Network Load Balancer (NLB) with a TCP listener for SAP GUI and enqueue ports, and place the application servers in an Auto Scaling group with a launch template that includes SAP start scripts.. A Network Load Balancer with TCP listeners for SAP GUI and enqueue ports, combined with an Auto Scaling group, provides automatic failover at the connection level. It preserves SAP GUI sessions and enqueue replication because it operates at Layer 4. Application Load Balancer and DNS-based routing do not handle SAP-specific protocols or session persistence, and disaster recovery tools require manual intervention.

Answer

Deploy the SAP application servers in an Auto Scaling group behind the ALB, and use an Amazon Route 53 health check to redirect traffic to a standby server.

Answer

Deploy a single SAP application server on a larger EC2 instance and use AWS Elastic Disaster Recovery to recover it to a standby instance in the same Availability Zone.

Answer

Use Amazon Route 53 with a latency-based routing policy to distribute SAP GUI connections to multiple application servers, and rely on SAP logon groups for failover.

Question 8

A company is designing a high-availability architecture for SAP NetWeaver on AWS. The SAP application servers run on EC2 instances across multiple Availability Zones, and the central services (ASCS/ERS) are managed by an Amazon ECS cluster. The company wants to ensure that the ASCS instance can fail over automatically in case of an EC2 instance failure. Which TWO components are required to achieve automatic failover of the ASCS? (Choose two.)

Accepted Answer

An overlay IP address that can be moved between cluster nodes.. Automatic failover of the ASCS requires a cluster resource manager to detect failures and orchestrate the failover, and an overlay IP to provide a consistent address that moves with the ASCS. These components work together to ensure that SAP application servers can reconnect seamlessly. Other options like Route 53, EBS Multi-Attach, or Global Accelerator do not provide the necessary cluster management or are not suitable for cross-AZ ASCS failover.

Answer

An AWS Global Accelerator endpoint group with health checks for the ASCS instances.

Answer

An Amazon Route 53 private hosted zone with health checks and failover routing.

Answer

A shared storage solution using Amazon EBS Multi-Attach volumes for the ASCS file system.

Question 9

A company is designing a disaster recovery strategy for an SAP HANA database on AWS. The production system runs on an x1e.32xlarge EC2 instance in the us-east-1 Region. The company requires a recovery point objective (RPO) of 5 minutes and a recovery time objective (RTO) of 30 minutes. Which TWO configurations should be included in the disaster recovery design? (Choose two.)

Accepted Answer

Configure SAP HANA system replication to a secondary site in a different AWS Region with asynchronous replication.. For cross-Region disaster recovery with a 5-minute RPO and 30-minute RTO, asynchronous SAP HANA system replication to a pre-provisioned secondary site is required. Automation of failover reduces RTO. Other options either do not provide the necessary RPO or are not suitable for SAP HANA.

Answer

Set up AWS Storage Gateway to replicate HANA data to Amazon S3 in another Region.

Answer

Deploy a secondary HANA instance in another Availability Zone within the same Region and use synchronous system replication.

Answer

Use Amazon EBS snapshots replicated to another Region with a frequency of every 5 minutes.

Question 10

A company is deploying a new SAP S/4HANA system on AWS. They need to ensure that the underlying storage for the HANA database meets SAP's performance requirements. The database will be 1.5 TB in size and is expected to have high random read/write IOPS. Which storage configuration should be used for the HANA data and log volumes?

Accepted Answer

Use io2 Block Express volumes with 64,000 IOPS for data and 20,000 IOPS for log.. For high-performance SAP HANA databases, io2 Block Express volumes provide the necessary high IOPS and low latency. The configuration with 64,000 IOPS for data and 20,000 for log meets SAP's requirements for a 1.5 TB database with high random I/O. Other options either use unsupported volume types or insufficient IOPS.

Answer

Use io1 volumes with 32,000 IOPS for data and 10,000 IOPS for log.

Answer

Use gp3 volumes with 16,000 IOPS and 1,000 MiB/s throughput for both data and log.

Answer

Use st1 volumes with 500 MiB/s throughput for data and gp2 volumes with 1,000 IOPS for log.

Question 11

A company is designing a disaster recovery strategy for its SAP HANA database on AWS. The primary site runs in the us-east-1 Region, and the company wants a secondary site in us-west-2 with an RPO of less than 5 minutes and an RTO of less than 30 minutes. The company wants to minimize operational overhead. Which TWO configurations should be included in the disaster recovery design? (Choose two.)

Accepted Answer

Deploy a secondary HANA instance in us-west-2 and configure a Pacemaker cluster with an overlay IP for automatic failover.. To achieve an RPO of less than 5 minutes and an RTO of less than 30 minutes for SAP HANA disaster recovery across Regions, the design should include asynchronous HSR to replicate data with minimal impact, and a Pacemaker cluster with an overlay IP to automate failover. Asynchronous HSR can meet the RPO requirement, while the cluster automates the promotion of the secondary instance and client redirection, reducing RTO. Other options either do not support HANA replication or cannot meet the RPO/RTO targets.

Answer

Set up Amazon S3 Cross-Region Replication for HANA backup files and restore from the latest backup in us-west-2.

Answer

Use AWS Database Migration Service (AWS DMS) with change data capture to replicate the HANA database to the secondary Region.

Answer

Use AWS Elastic Disaster Recovery to replicate the HANA EC2 instances to us-west-2 with continuous block-level replication.

Question 12

A company is planning to migrate its SAP Business Suite on Oracle database to AWS. The company wants to minimize the migration time and ensure that the database remains consistent during the migration. Which AWS service should be used to migrate the database?

Accepted Answer

SAP-certified backup and restore using native Oracle tools with Amazon EBS snapshots.. For migrating SAP Business Suite on Oracle to AWS, the recommended approach is to use SAP-certified backup and restore procedures with native Oracle tools, combined with EBS snapshots. This ensures database consistency and is supported by SAP. Other services like DMS or SMS are not suitable for this specific migration.

Answer

AWS Server Migration Service (SMS) to replicate the on-premises servers to AWS.

Answer

AWS Database Migration Service (DMS) with Oracle as the source and Amazon RDS for Oracle as the target.

Answer

AWS DataSync to copy the database files to Amazon EBS volumes.

Question 13

A company is designing an SAP HANA scale-out system on AWS using multiple EC2 instances. The system will use a shared file system for the HANA data and log volumes to allow all worker nodes to access the same storage. Which TWO AWS services should be used to provide the shared file system for the SAP HANA scale-out deployment? (Choose two.)

Accepted Answer

Amazon FSx for NetApp ONTAP. SAP HANA scale-out on AWS requires shared block storage that is certified for HANA. Amazon EBS Multi-Attach io2 Block Express volumes provide shared block storage within an Availability Zone, and Amazon FSx for NetApp ONTAP is certified for HANA and offers a shared file system. Other options like Amazon EFS, FSx for Lustre, and S3 file gateway do not meet the performance or certification requirements for HANA data and log volumes.

Answer

Amazon S3 with a file gateway

Answer

Amazon EFS

Answer

Amazon FSx for Lustre

Question 14

A company runs an SAP S/4HANA system on AWS. The system uses an Amazon RDS for SAP HANA database? No, SAP HANA is not supported on RDS. The company uses an EC2 instance for the SAP HANA database. The company needs to ensure that the database can be recovered in a different AWS Region in the event of a regional disaster. The recovery point objective (RPO) is 1 hour, and the recovery time objective (RTO) is 4 hours. Which solution should be implemented?

Accepted Answer

Set up SAP HANA system replication to a secondary EC2 instance in a different AWS Region, and configure asynchronous replication with a 1-hour log shipping interval.. SAP HANA system replication to a different AWS Region with asynchronous log shipping can achieve a 1-hour RPO and a 4-hour RTO. The secondary instance runs in a different Region, providing protection against regional failures. Asynchronous replication allows for some data loss but can be configured to ship logs at intervals that meet the RPO. This is the recommended approach for cross-Region disaster recovery of SAP HANA on AWS.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate the SAP HANA database to an Amazon RDS for PostgreSQL instance in another Region.

Answer

Create a daily Amazon EBS snapshot of the SAP HANA data and log volumes, and copy the snapshots to another Region using Amazon S3 Cross-Region Replication.

Answer

Configure SAP HANA system replication to a secondary EC2 instance in another Availability Zone within the same Region.

Question 15

A company runs SAP Business Suite on an SAP HANA database on AWS. The database uses EBS gp2 volumes. The operations team notices high latency during peak hours. The metrics show that the volume queue depth is consistently above the recommended threshold. What is the MOST cost-effective change to reduce latency?

Accepted Answer

Increase the size of the existing EBS gp2 volume to a larger size.. Increasing the size of an existing gp2 volume is the most cost-effective solution because gp2 volumes have a baseline performance of 3 IOPS per GB, and they can burst up to 3,000 IOPS for volumes up to 1,000 GB. By increasing the volume size, you raise the baseline IOPS, which reduces the queue depth without incurring the higher per-GB cost of io1 or io2 volumes. This directly addresses the high latency caused by queue depth exceeding the recommended threshold during peak hours.

Answer

Migrate from gp2 to io2 EBS volumes with the same size.

Answer

Modify the volume to use Provisioned IOPS (io1) with a higher IOPS value.

Answer

Add an additional EBS volume and stripe the volumes using LVM.
