Accepted Answer

Amazon FSx for NetApp ONTAP. Amazon FSx for NetApp ONTAP is the correct choice because it supports both NFS and SMB protocols, provides POSIX-compliant file systems, and can be configured for Multi-AZ high availability with automatic failover. This meets all the requirements for a shared SAP NetWeaver file system accessed by Linux and Windows application servers.

Answer

Amazon Elastic File System (Amazon EFS)

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3 with AWS Storage Gateway File Gateway

Question 2

An SAP administrator runs the command shown in the exhibit. The volume is attached to an EC2 instance. The administrator plans to increase the volume size to 1000 GiB. After resizing, the volume type remains gp2. What is the expected baseline IOPS for the resized volume?

Accepted Answer

3000 IOPS. Gp2 volumes have a baseline IOPS of 3 IOPS per GiB, up to a maximum of 16,000 IOPS. For a 1000 GiB gp2 volume, the calculation is 1000 × 3 = 3000 IOPS, which is below the 16,000 IOPS cap, so the expected baseline IOPS is exactly 3000.

Answer

4500 IOPS

Answer

16,000 IOPS

Answer

1500 IOPS

Question 3

A company is deploying SAP HANA on AWS using an EC2 instance with a memory-optimized instance type. The company wants to ensure that the storage for the HANA data and log volumes meets SAP's performance requirements. The company has chosen Amazon EBS gp3 volumes. What should the company do to ensure that the gp3 volumes provide the required IOPS and throughput for SAP HANA?

Accepted Answer

Provision additional IOPS and throughput on the gp3 volumes.. Amazon EBS gp3 volumes allow independent provisioning of IOPS and throughput. To meet SAP HANA performance requirements, you must explicitly provision the necessary IOPS and throughput on the gp3 volumes. Increasing volume size does not automatically scale performance for gp3, and while RAID 0 or io2 volumes could provide performance, the direct action for gp3 is to provision the required IOPS and throughput.

Answer

Increase the volume size to automatically increase IOPS and throughput.

Answer

Use io2 Block Express volumes instead of gp3.

Answer

Enable EBS optimized instances and attach multiple gp3 volumes in a RAID 0 configuration.

Question 4

A company is running SAP HANA on AWS and needs to ensure that the database can be backed up to Amazon S3 without impacting performance. The SAP administrator wants to use SAP HANA's native backup tools. Which method should the administrator use to back up the SAP HANA database directly to Amazon S3?

Accepted Answer

Use the SAP HANA backup command with a backint configuration that points to an AWS Backint Agent for SAP HANA.. The AWS Backint Agent for SAP HANA is a certified backint provider that enables SAP HANA to back up directly to Amazon S3 using native backup tools. It supports features like parallel uploads, compression, and encryption, and is the recommended method for S3 backups. Other options are either not native, not application-consistent, or not supported.

Answer

Use Amazon EBS snapshots of the SAP HANA data and log volumes, and copy the snapshots to Amazon S3.

Answer

Create a cron job that runs hdbsql to export the database to a local file and then uses the AWS CLI to copy the file to Amazon S3.

Answer

Configure SAP HANA to use the Amazon S3 REST API directly by specifying the S3 bucket URL in the backup command.

Question 5

A company is running SAP HANA on AWS and needs to ensure that the database can be recovered quickly in the event of a failure. They want to implement a backup strategy that includes both database backups and storage snapshots. Which TWO actions should they take to meet this requirement? (Choose two.)

Accepted Answer

Create Amazon EBS snapshots of the SAP HANA data and log volumes on a regular schedule using Amazon Data Lifecycle Manager.. To ensure quick recovery, a combination of database-level backups and storage snapshots is recommended. Using AWS Backint Agent to back up SAP HANA to Amazon S3 provides durable, off-instance backups. Additionally, scheduling EBS snapshots with Amazon Data Lifecycle Manager offers fast volume-level recovery. Together, these actions meet the requirement for a robust backup strategy. Other options are either not backup mechanisms or not supported for SAP HANA on AWS.

Answer

Configure SAP HANA to write backups directly to an Amazon S3 bucket using the S3 API without the AWS Backint Agent.

Answer

Use AWS Storage Gateway to create a cached volume gateway that stores SAP HANA backups on-premises.

Answer

Enable SAP HANA System Replication to a secondary instance in another Availability Zone and use that as the primary backup mechanism.

Question 6

An SAP system on AWS is using a shared /usr/sap/trans directory mounted on an NFS file server. The file server is an EC2 instance with a standard gp2 EBS volume. During SAP transports, users experience slow response times and occasional timeouts. The system administrator suspects the file server is the bottleneck. Which solution would provide a fully managed, highly available, and performant file share for SAP transport files?

Accepted Answer

Migrate /usr/sap/trans to Amazon FSx for NetApp ONTAP with Multi-AZ deployment.. Amazon FSx for NetApp ONTAP provides a fully managed, Multi-AZ, highly available NFS/SMB file system with sub-millisecond latencies and NetApp features (snapshots, dedup, FlexClone) that SAP transport directories benefit from. It removes the single-EC2-instance bottleneck and delivers consistent throughput for /usr/sap/trans, which is exactly what SAP on AWS reference architectures recommend for shared transport.

Answer

Configure multiple EC2 file servers with a load balancer.

Answer

Replace the EC2 file server with Amazon EFS.

Answer

Increase the EBS volume size of the file server to improve throughput.

Question 7

A company is running SAP HANA on AWS and needs to ensure that the database can be recovered to a specific point in time within the last 7 days. The HANA database is using continuous log backups to Amazon S3. Which additional configuration is required to enable point-in-time recovery?

Accepted Answer

Enable HANA's automatic log backup and ensure that the log backups are retained for at least 7 days in Amazon S3.. Point-in-time recovery for SAP HANA requires continuous log backups that are retained for the desired recovery window. Enabling automatic log backup to Amazon S3 with a retention policy of at least 7 days ensures that the logs are available. Full backups alone or system replication do not provide PITR. S3 versioning is a data protection feature but not a substitute for proper log retention.

Answer

Enable Amazon S3 versioning on the bucket used for HANA backups.

Answer

Schedule daily full backups of the HANA database to Amazon S3 and retain them for 7 days.

Answer

Configure HANA system replication to a secondary instance in another Availability Zone.

Question 8

Which THREE factors must be considered when choosing an EC2 instance type for SAP HANA production workloads?

Accepted Answer

EBS-optimized support for consistent I/O. Option C (EBS-optimized support for consistent I/O) is correct because SAP HANA production workloads demand predictable, high-throughput storage performance, and EBS-optimized instances provide dedicated bandwidth to Amazon EBS, avoiding contention with network traffic. Option D (SAP certification of the instance type) is correct because SAP HANA production deployments must run on instance types that are officially certified by SAP, ensuring the hardware meets SAP's performance and reliability requirements. Option E (Memory (RAM) size required by SAP HANA) is correct because SAP HANA is an in-memory database, so the instance must have enough RAM to hold the entire working dataset in memory, making memory capacity a primary sizing factor. Option A (Burstable CPU performance with T3 instances) is not appropriate because T3 instances use a burstable CPU credit model that cannot guarantee sustained high CPU performance needed for production SAP HANA. Option B (GPU compute capability) is not a required factor because SAP HANA production workloads are CPU- and memory-intensive rather than GPU-accelerated.

Answer

Burstable CPU performance (T3 instances)

Answer

GPU compute capability

Question 9

A company runs an SAP NetWeaver application on AWS with multiple application servers behind an Application Load Balancer (ALB). The company wants to ensure that the application servers are automatically replaced if they fail health checks. The company also wants to minimize costs by using a mix of On-Demand and Spot Instances. Which solution should the company implement?

Accepted Answer

Create an Auto Scaling group with a launch template that specifies a mixed instances policy, and attach the Auto Scaling group to the ALB target group.. An Auto Scaling group with a mixed instances policy and attachment to the ALB target group provides automatic replacement of unhealthy instances and allows a mix of On-Demand and Spot Instances for cost savings. The ALB health checks ensure that only healthy instances receive traffic, and the Auto Scaling group maintains the desired capacity. Other options either lack automatic replacement or are not suitable for SAP NetWeaver deployments.

Answer

Use an EC2 Fleet with a diversified allocation strategy and configure the ALB to route traffic only to healthy instances.

Answer

Configure an AWS Lambda function to monitor EC2 instance health and replace instances using AWS Systems Manager Automation.

Answer

Deploy the application servers as an Amazon ECS service with an Application Load Balancer and use AWS Fargate Spot.

Question 10

A company is planning to migrate an SAP ERP Central Component (ECC) system running on Oracle Database to AWS. The database will be re-platformed to SAP HANA on an Amazon EC2 instance. The migration team must validate that the target instance and storage meet SAP HANA requirements before cutover. Which TWO validation activities should the team perform on the target EC2 instance? (Choose two.)

Accepted Answer

Verify that the EC2 instance type appears in the SAP HANA Certified and Supported SAP HANA Hardware Directory for the planned AWS Region and that the EBS volume types match SAP's published storage recommendations.. Before cutover, the team must confirm both that the target platform is certified for HANA and that the actual instance and storage deliver the required KPIs. Checking the SAP HANA Certified and Supported SAP HANA Hardware Directory against the chosen instance type and EBS volume types establishes supportability, while running SAP's hardware and cloud measurement tools against the live EC2 instance and its volumes produces empirical performance evidence for the specific deployment.

Answer

Run the SAP NetWeaver transport management system consistency check against the target instance to confirm that the HANA database can accept ABAP transports after cutover.

Answer

Configure SAP HANA system replication between the source Oracle Database and the target HANA instance so that data is continuously synchronized during the validation period.

Answer

Enable Oracle Automatic Storage Management (ASM) on the target EBS volumes to provide the striping and mirroring that SAP HANA requires for /hana/data.

Question 11

A company is migrating a production SAP NetWeaver ABAP system from on-premises to AWS. The SAP system uses a shared file system for /sapmnt, /usr/sap/trans, and global transport directories. The migration must preserve the existing SAP SID, hostname, and mount points. The company wants to minimize changes to the SAP application and ensure that the shared file system is highly available across Availability Zones. Which AWS storage solution should be used for the shared file system?

Accepted Answer

Amazon EFS with mount targets in multiple Availability Zones. SAP NetWeaver on Linux requires a shared NFS file system for central services and transport directories. Amazon EFS delivers a managed, multi-AZ NFS solution that supports the necessary POSIX permissions and locking. It allows the SAP system to retain its SID, hostname, and mount points without application changes, and provides the high availability needed for production.

Answer

Amazon FSx for Lustre

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3 mounted using s3fs-fuse

Question 12

A company is deploying SAP HANA on a single Amazon EC2 instance in AWS. The SAP HANA database requires high availability and disaster recovery. The company wants to use native AWS services to minimize cost and operational overhead. Which TWO configurations should a SAP on AWS specialist recommend to meet these requirements? (Choose two.)

Accepted Answer

Configure SAP HANA system replication between two EC2 instances in different Availability Zones within the same AWS Region.. SAP HANA system replication across Availability Zones provides high availability by enabling failover to a secondary instance in another AZ. Amazon S3 Cross-Region Replication provides disaster recovery by copying backups to another Region. Together, they form a native AWS HA/DR solution with minimal operational overhead. The other options either do not provide HA/DR or are not native AWS services for this purpose.

Answer

Deploy SAP HANA on an Amazon EC2 instance with a cluster placement group and enable detailed monitoring.

Answer

Configure an Amazon Route 53 health check to automatically restart the EC2 instance if it fails.

Answer

Use AWS Storage Gateway to replicate SAP HANA data to on-premises storage.

Question 13

A company is migrating its SAP NetWeaver application servers from on-premises to AWS. The SAP application servers run on Linux and are not dependent on a specific hostname. The migration must be completed with minimal downtime, and the team wants to avoid reinstalling the SAP software. Which migration approach should be used?

Accepted Answer

Use AWS Application Migration Service (AWS MGN) to replicate the servers to AWS and launch them as EC2 instances.. AWS Application Migration Service (AWS MGN) is the recommended service for lift-and-shift migrations of SAP application servers to AWS. It replicates servers at the block level, enabling minimal downtime and avoiding the need to reinstall SAP software. Since the servers do not require a specific hostname, this approach is ideal. Other options either involve more downtime, are designed for databases, or are deprecated.

Answer

Use SAP Software Provisioning Manager (SWPM) to perform a system copy with a distributed installation.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the SAP application servers to AWS.

Answer

Use AWS Server Migration Service (AWS SMS) to replicate the servers to AWS and launch them as EC2 instances.

Question 14

A company is migrating an SAP NetWeaver ABAP system to AWS. The system uses a shared file system for /sapmnt and /usr/sap/trans. The company requires a highly available, POSIX-compliant shared file system that supports SMB and NFS protocols and can be accessed by both Linux and Windows application servers. The solution must provide automatic failover across Availability Zones. Which AWS storage service should the company use?

Accepted Answer

Amazon RDS for Oracle. Amazon RDS for Oracle is the correct choice because it provides a managed Oracle database that is certified for SAP NetWeaver. It allows the company to keep the Oracle database engine while reducing administrative tasks such as backups and patching. Other managed database services either use a different engine or are not relational, so they do not meet the requirement to remain on Oracle.

Answer

Amazon RDS for SQL Server

Answer

Amazon DynamoDB

Answer

Amazon RDS for PostgreSQL

Question 15

A company is planning to migrate a large SAP HANA database (20 TB) from on-premises to AWS. The migration must minimize downtime and ensure data consistency. The company has a 10 Gbps AWS Direct Connect connection and wants to use a method that allows for incremental data synchronization before the final cutover. Which approach should be used?

Accepted Answer

Use SAP HANA system replication to replicate the database to an Amazon EC2 instance running SAP HANA, then perform a takeover during the cutover window.. SAP HANA system replication is the optimal method for migrating a large HANA database with minimal downtime. It continuously replicates changes, allowing for a short cutover. The Direct Connect connection supports the required bandwidth for initial synchronization and ongoing replication. Other methods either do not support HANA, result in inconsistent data, or require longer downtime.

Answer

Perform a backup of the HANA database to Amazon S3 using SAP HANA backup, then restore it to an EC2 instance during the cutover weekend.

Answer

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

Answer

Use AWS DataSync to copy the HANA data and log files to Amazon S3, then restore them to an EC2 instance using SAP HANA backup and recovery.
