AWS CloudFormation

Answer

Amazon S3

Question 2

A company is migrating its SAP ERP system to AWS. The system has strict high availability requirements with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 2 hours. The SAP application and database (SAP HANA) must be in the same AWS Region but can be in different Availability Zones. Which architecture should the company use to meet these requirements?

Accepted Answer

Deploy SAP HANA in a Multi-AZ cluster using synchronous replication across two Availability Zones, with the SAP application servers in an Auto Scaling group across the same AZs.. It uses synchronous replication for SAP HANA across two Availability Zones, which ensures zero data loss and meets the RPO of 15 minutes. The Multi-AZ cluster with automatic failover achieves the RTO of 2 hours, while the SAP application servers in an Auto Scaling group across the same AZs provide high availability and load balancing. This architecture aligns with AWS best practices for SAP HANA HA, leveraging HANA System Replication (HSR) in sync mode.

Answer

Deploy SAP HANA in a single Availability Zone with asynchronous replication to a secondary instance in another AZ, and use manual failover.

Answer

Deploy SAP HANA on a single EC2 instance with EBS snapshots every 5 minutes, and use a secondary instance in another AZ with snapshots restored.

Answer

Deploy SAP HANA on a single EC2 instance with hourly backups to Amazon S3 and a script to restore the backup on a new instance in a different AZ.

Question 3

A company is deploying a new SAP NetWeaver application server on AWS. The SAP Basis team wants to ensure that the application server can be quickly recovered in case of an instance failure. The application server runs on a single EC2 instance with an EBS volume for the SAP binaries and instance-specific data. The company requires an RTO of 30 minutes and an RPO of 5 minutes. Which design should the SAP administrator implement?

Accepted Answer

Use AWS Elastic Disaster Recovery (DRS) to continuously replicate the EC2 instance and its EBS volumes to a staging area, and configure a recovery plan to launch the instance in case of failure.. AWS Elastic Disaster Recovery (DRS) provides continuous replication of the entire server, including the operating system, applications, and data, to a staging area. It enables recovery with minimal data loss (RPO in seconds) and can launch a recovery instance quickly, meeting the 30-minute RTO. For SAP application servers that are not stateless, DRS is a robust solution for disaster recovery.

Answer

Place the EC2 instance in an Auto Scaling group with a minimum and maximum size of 1, and configure a launch template with the EBS volume snapshot ID.

Answer

Configure the EC2 instance with a detailed CloudWatch alarm that triggers an AWS Lambda function to restart the instance.

Answer

Create an Amazon Machine Image (AMI) of the EC2 instance daily and store it in Amazon S3. In case of failure, launch a new instance from the latest AMI.

Question 4

A company is planning to migrate its SAP Business Suite on Oracle database to AWS. The database is currently running on physical servers with direct-attached storage. The company wants to use Amazon EBS for the database volumes. Which EBS volume type should be used for the Oracle data files to achieve the best performance?

Accepted Answer

Provisioned IOPS SSD (io2). Oracle databases in SAP environments require high-performance storage with consistent low latency and high IOPS. Provisioned IOPS SSD (io2) volumes are specifically designed for such demanding workloads, offering the highest levels of performance and durability among EBS volume types. They allow fine-grained provisioning of IOPS and are recommended by AWS for production SAP databases.

Answer

General Purpose SSD (gp3)

Answer

Throughput Optimized HDD (st1)

Answer

Cold HDD (sc1)

Question 5

A company is planning to run a scale-out SAP HANA database on AWS to support a large SAP Business Warehouse workload. The design must allow the worker nodes to share the same HANA data and log storage while meeting SAP's requirements for scale-out on AWS. Which TWO design elements should the company include? (Choose two.)

Accepted Answer

A shared file system such as Amazon FSx for Lustre or a supported clustered file system mounted on all HANA worker nodes for the data and log volumes.. HANA scale-out on AWS requires a shared data and log area accessible to all worker nodes, provided by a validated shared or clustered file system, plus SAP-certified EC2 instance types for the master and worker hosts. Isolated per-node volumes and general-purpose file systems do not meet the shared-storage and performance requirements of a supported scale-out topology.

Answer

A separate EBS io2 volume attached exclusively to each worker node for its own data and log volumes, isolated from the other nodes.

Answer

A single r5.24xlarge instance configured with multiple EBS volumes striped together to emulate scale-out within one host.

Answer

Amazon EFS mounted on all worker nodes to provide the shared data and log area for HANA.

Question 6

A company is deploying SAP S/4HANA on AWS and needs to design the storage layout for the SAP HANA database. The company requires high performance and low latency for the database, and wants to ensure that the storage can be quickly restored in case of a failure. The company also wants to minimize costs. The SAP HANA database is expected to be 2 TB in size. Which storage configuration should the SAP administrator recommend?

Accepted Answer

Use multiple Provisioned IOPS SSD (io2) EBS volumes for data and log, and configure them in a RAID 0 array for the data volume and a separate io2 volume for the log volume.. SAP HANA on AWS requires storage that meets SAP's performance and certification requirements. Provisioned IOPS SSD (io2) volumes are certified and provide high IOPS and low latency. For the data volume, striping multiple io2 volumes in a RAID 0 array increases IOPS and throughput. For the log volume, a separate io2 volume ensures low latency and high IOPS for write-intensive log operations. This design provides high performance and allows for independent scaling. It also supports quick restore from snapshots. Other volume types like gp3, st1, or single io1 volumes may not meet performance or certification requirements.

Answer

Use a single 2-TB General Purpose SSD (gp3) EBS volume for the data and log volumes, and take regular EBS snapshots.

Answer

Use a single 2-TB Throughput Optimized HDD (st1) EBS volume for the data volume and a single 1-TB st1 volume for the log volume.

Answer

Use a single 2-TB io1 EBS volume for the data volume and a single 1-TB io1 volume for the log volume, with no RAID configuration.

Question 7

A company is running SAP Business Suite on HANA on AWS. The SAP HANA database is deployed on a single EC2 instance with EBS volumes. The company wants to ensure that the database can be recovered quickly in the event of an Availability Zone failure. The RTO is 15 minutes and the RPO is 5 minutes. Which disaster recovery strategy should be implemented?

Accepted Answer

Configure SAP HANA system replication to a standby instance in a different Availability Zone, with continuous log shipping. SAP HANA system replication with continuous log shipping is the optimal disaster recovery solution for meeting a 15-minute RTO and 5-minute RPO. It maintains a standby system in a different Availability Zone that is continuously updated with redo logs, enabling fast takeover with minimal data loss. Other options like snapshots, AMIs, or S3 replication cannot achieve the required recovery times.

Answer

Create an Amazon Machine Image (AMI) of the EC2 instance daily and launch a new instance from it in another Availability Zone when needed

Answer

Use AWS Backup to take hourly snapshots of the EBS volumes and restore them in another Availability Zone during a disaster

Answer

Use Amazon S3 Cross-Region Replication to replicate HANA backups to another region and restore from there

Question 8

A company runs its SAP HANA database on an EC2 instance (r5.8xlarge) with 8 EBS gp2 volumes (1 TB each) in a RAID 0 stripe. The database is critical and requires high availability. The current architecture uses a single EC2 instance in one Availability Zone. The company wants to implement a disaster recovery solution with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 4 hours. The DR site must be in a different AWS Region. The SAP HANA database size is 4 TB. The company has a 1 Gbps Direct Connect connection between the primary and DR Regions. The database workload is write-intensive with an average write throughput of 200 MB/s. Which solution meets the RPO and RTO requirements?

Accepted Answer

Set up HANA System Replication (HSR) in asynchronous mode from the primary to a secondary EC2 instance in the DR Region. Use the same instance type and EBS configuration. In case of failure, perform a HSR takeover.. HANA System Replication (HSR) in asynchronous mode continuously ships redo log entries from the primary to the secondary instance, giving an RPO typically measured in seconds to low minutes — well within the 15-minute requirement. Because the secondary EC2 instance is pre-provisioned with the same instance type and EBS RAID 0 layout, a takeover can complete in minutes, satisfying the 4-hour RTO. HSR is SAP's native HA/DR mechanism and is the only option that provides continuous, near-real-time replication of the 4 TB database across Regions.

Answer

Take EBS snapshots of the RAID array every 15 minutes and replicate them to the DR Region using EBS snapshot copy. In the DR Region, restore the snapshots to new volumes and attach them to a new EC2 instance.

Answer

Back up the HANA database to Amazon S3 every 15 minutes using the HANA backup tool, and set up cross-Region replication for the S3 bucket. In the DR Region, restore the latest backup to a new EC2 instance.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate changes to a target HANA database in the DR Region.

Question 9

A company runs an SAP S/4HANA system on AWS. The SAP HANA database is deployed on an Amazon EC2 instance with multiple EBS volumes. The company needs to ensure that the HANA database can be recovered to any point in time within the last 14 days. Which AWS service or feature should be used to meet this requirement?

Accepted Answer

SAP HANA database backup to Amazon S3 with backint and continuous log backups. Point-in-time recovery for SAP HANA requires continuous log backups in addition to regular full backups. The SAP HANA backint API allows you to back up directly to Amazon S3, and by enabling automatic log backups, you can recover to any point in time within the retention period. EBS snapshots and AWS Backup do not provide continuous log capture, and Amazon RDS does not support SAP HANA. Thus, the backint-based backup to S3 is the correct solution.

Answer

AWS Backup with a backup plan that includes continuous backups

Answer

Amazon RDS for SAP HANA with automated backups and point-in-time recovery

Answer

Amazon EBS snapshots with a lifecycle policy to retain 14 days

Question 10

A company is designing a high availability architecture for SAP HANA on AWS. The HANA database must be able to automatically fail over to a standby node in the event of an EC2 instance failure. The company wants to minimize downtime and ensure data integrity. Which TWO components are required to achieve automatic failover for SAP HANA on AWS? (Choose two.)

Accepted Answer

SAP HANA system replication configured in synchronous mode. Automatic failover for SAP HANA on AWS requires SAP HANA system replication to keep the standby node synchronized, and a cluster manager like Pacemaker with STONITH to detect failures and orchestrate the failover while preventing split-brain. These components together ensure minimal downtime and data integrity. Other options like S3 replication, DMS, or Route 53 do not provide the necessary database-level failover capabilities.

Answer

Amazon S3 bucket configured for cross-region replication

Answer

Amazon Route 53 health checks with DNS failover

Answer

AWS Database Migration Service (DMS) with change data capture

Question 11

A company is deploying SAP NetWeaver Application Server ABAP on AWS. The SAP Basis team wants to use the SAP-provided automation to provision the EC2 instances, install the SAP software, and configure the operating system according to SAP best practices. The team wants to avoid manual installation steps and reduce deployment time. Which AWS service should the architect recommend?

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP is the SAP-specific deployment service that automates the provisioning of AWS infrastructure and the installation of SAP software using SAP-certified automation. It handles sizing recommendations, network and security configuration, and the operating system preparation required by SAP. For a team that wants to avoid manual installation and shorten deployment time for SAP NetWeaver ABAP, Launch Wizard is the appropriate choice rather than building custom automation with general-purpose services.

Answer

AWS CloudFormation with a custom template written from scratch

Answer

AWS Systems Manager Automation runbooks

Answer

AWS Elastic Beanstalk with a custom platform

Question 12

A company is deploying a highly available SAP NetWeaver ABAP system on AWS. The system consists of a central services instance (ASCS), an enqueue replication server (ERS), and multiple application servers. The company wants to ensure that the ASCS and ERS instances are highly available across two Availability Zones. Which TWO configurations should be implemented to achieve this? (Choose two.)

Accepted Answer

Configure the ASCS and ERS instances in a cluster with an overlay IP address, and use Amazon Route 53 with a failover routing policy to direct traffic to the active instance.. High availability for SAP NetWeaver ASCS and ERS on AWS requires a cluster solution to manage the overlay IP address and automate failover across Availability Zones. SUSE Linux Enterprise High Availability Extension or Windows Server Failover Clustering are supported for this purpose. Additionally, Amazon Route 53 with failover routing can be used to direct clients to the active instance by updating DNS based on health checks. These two configurations together ensure that the central services remain available if an Availability Zone fails. Auto Scaling groups and EFS do not provide the necessary cluster management and failover capabilities.

Answer

Place the ASCS and ERS instances in an Auto Scaling group with a minimum and maximum size of 1, and use a Network Load Balancer to distribute traffic.

Answer

Deploy the ASCS and ERS instances in separate Auto Scaling groups, each with a minimum and maximum size of 1, and use a Network Load Balancer to distribute traffic.

Answer

Use Amazon Elastic File System (Amazon EFS) to share the /usr/sap filesystem between the ASCS and ERS instances, and rely on EFS for automatic failover.

Question 13

A company runs SAP NetWeaver AS ABAP on AWS with an Oracle database on a single EC2 instance. The database is 2 TB and grows by 10% annually. The company requires a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 2 hours. The current backup strategy uses nightly RMAN backups to Amazon S3. Which change should the company implement to meet the RPO requirement?

Accepted Answer

Enable Oracle Data Guard in maximum performance mode with a standby database on a second EC2 instance in the same AWS Region, and configure asynchronous redo transport.. To achieve a 15-minute RPO, the company needs near-real-time replication of database changes. Oracle Data Guard with asynchronous redo transport in maximum performance mode provides a standby database that is typically only seconds behind, meeting the RPO. It also supports fast failover to meet the 2-hour RTO. This is a supported and common configuration for SAP on Oracle on AWS, and it is more practical than frequent RMAN backups or cross-Region synchronous replication.

Answer

Configure Oracle Active Data Guard with a standby database in a different AWS Region and enable synchronous redo transport.

Answer

Increase the frequency of RMAN backups to Amazon S3 to every 15 minutes and enable Oracle block change tracking.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate the Oracle database to an Amazon RDS for Oracle instance, and use that as a standby.

Question 14

An SAP Basis administrator is designing a high-availability solution for SAP HANA on AWS. The requirement is to achieve an RTO of less than 5 minutes and an RPO of less than 1 minute. The administrator plans to use SAP HANA System Replication. Which additional AWS configuration is necessary to meet these objectives?

Accepted Answer

Configure HANA System Replication in synchronous mode with a multi-AZ deployment and use an overlay IP for automatic failover.. To achieve low RTO and RPO, SAP HANA System Replication should be configured in synchronous mode across multiple Availability Zones. This ensures data is replicated with zero data loss and allows automatic failover. An overlay IP (managed by a cluster solution like Pacemaker) enables the application to connect to the new primary quickly, meeting the stringent recovery objectives.

Answer

Deploy HANA on a single EC2 instance with multiple EBS volumes and use RAID 0 for improved performance and redundancy.

Answer

Use Amazon EBS snapshots to restore the HANA database to a new instance in another AZ, and update the SAP application server configuration manually.

Answer

Configure HANA System Replication in asynchronous mode with a single-AZ deployment and use Amazon Route 53 health checks for failover.

Question 15

A company runs SAP ERP Central Component (ECC) on AWS with an Oracle database. The SAP application servers are on c5.9xlarge instances and the database is on an r5.12xlarge instance. The company wants to implement a disaster recovery (DR) solution with an RPO of 1 hour and an RTO of 4 hours. The primary site is in us-east-1 and the DR site will be in us-west-2. Which strategy should be used for the Oracle database to meet these requirements at the lowest cost?

Accepted Answer

Configure Oracle Data Guard with a standby database in us-west-2 using asynchronous redo transport in maximum performance mode.. For a cost-effective DR solution with a 1-hour RPO and 4-hour RTO across Regions, Oracle Data Guard with asynchronous redo transport in maximum performance mode is ideal. It provides near-real-time replication with minimal impact on the primary database, ensuring the standby is up-to-date within minutes. Failover can be performed quickly, meeting the 4-hour RTO. This approach is more reliable and faster than backup/restore or storage replication methods, and it avoids the performance penalties of synchronous replication.

Answer

Configure Oracle Data Guard with a standby database in us-west-2 using synchronous redo transport in maximum availability mode.

Answer

Use Oracle RMAN to take hourly incremental backups to Amazon S3 in us-west-2, and restore them to an EC2 instance during a disaster.

Answer

Use AWS Storage Gateway to replicate the Oracle database volumes to us-west-2, and attach them to a pre-provisioned EC2 instance during a disaster.
