Amazon S3 with a file gateway

Answer

Amazon EFS with provisioned throughput

Answer

Amazon FSx for Lustre

Question 3

A company is running an SAP S/4HANA system on AWS with a primary application server (PAS) and an additional application server (AAS) in a single Availability Zone. The company wants to improve the availability of the application tier by deploying the AAS in a second Availability Zone. The SAP HANA database is in the first Availability Zone and is not highly available. The company wants to ensure that if the AAS in the second Availability Zone fails, the PAS can continue to operate without manual intervention. What should the company do to meet these requirements?

Accepted Answer

Deploy the AAS in the second Availability Zone and configure the SAP system to use the AAS as a separate application server with its own instance profile.. The correct action is to deploy the AAS in the second Availability Zone as a separate application server with its own instance profile. SAP application servers are independent; if one fails, the others continue to operate. The PAS does not depend on the AAS for its operation. Therefore, simply deploying the AAS in a separate AZ ensures that its failure does not affect the PAS, meeting the requirement without manual intervention.

Answer

Configure an Auto Scaling group for the AAS with a minimum capacity of one and a maximum of one, spanning both Availability Zones.

Answer

Configure an Application Load Balancer with cross-zone load balancing enabled and health checks for the AAS.

Answer

Ensure that the SAP HANA database is highly available across both Availability Zones.

Question 4

A company is running SAP HANA on a single Amazon EC2 instance in one Availability Zone. The company wants to implement a high-availability solution that automatically recovers from an AZ failure with minimal data loss. Which solution should be implemented?

Accepted Answer

Deploy SAP HANA with synchronous replication to a secondary instance in another Availability Zone using SAP HANA System Replication (HSR).. SAP HANA System Replication (HSR) with synchronous mode replicates data to a secondary instance in another Availability Zone, ensuring zero data loss and automatic failover. This is the standard high-availability configuration for SAP HANA on AWS. EBS snapshots, asynchronous replication in the same AZ, and placement groups do not provide the required protection against AZ failures with minimal data loss.

Answer

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

Answer

Configure SAP HANA with asynchronous replication to a secondary instance in the same Availability Zone.

Answer

Use Amazon EBS snapshots to restore the HANA database in another Availability Zone.

Question 5

A company is deploying SAP S/4HANA on AWS and needs to ensure that the SAP HANA database can be recovered quickly in the event of a disaster. The company has a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour. The database is running on an Amazon EC2 instance with Amazon EBS volumes. Which solution should they implement to meet these objectives?

Accepted Answer

Use SAP HANA System Replication (HSR) to a secondary EC2 instance in another AWS Region, with asynchronous replication mode.. SAP HANA System Replication in asynchronous mode to another AWS Region provides continuous replication with an RPO of minutes, and failover can be automated to meet the 1-hour RTO. This is the recommended disaster recovery solution for SAP HANA on AWS when cross-Region DR is required.

Answer

Use SAP HANA System Replication (HSR) to a secondary EC2 instance in another Availability Zone, with synchronous replication mode.

Answer

Take daily Amazon EBS snapshots of the HANA data and log volumes and copy them to another Region.

Answer

Configure AWS Backup to take snapshots of the EBS volumes every 15 minutes and store them in a different AWS Region.

Question 6

A company is running SAP HANA on AWS and wants to implement a backup strategy that meets SAP's recommendations for data durability and rapid recovery. The HANA database is on an Amazon EC2 instance with EBS volumes. Which TWO actions should be taken to ensure that backups are stored durably and can be restored quickly? (Choose two.)

Accepted Answer

Enable Amazon S3 Cross-Region Replication for the bucket storing HANA backups to ensure durability across regions.. The two recommended actions are to use the BACKINT interface with an AWS-certified backup agent to write backups directly to Amazon S3, and to enable S3 Cross-Region Replication for additional durability. BACKINT to S3 is SAP-certified and simplifies backup and recovery, while Cross-Region Replication protects against regional failures. Other options either do not provide application-consistent backups or lack the required durability.

Answer

Store backups on an Amazon FSx for Lustre file system for high-performance recovery.

Answer

Use SAP HANA's native backup command to write backups to a local EBS volume, then copy them to Amazon S3 using AWS DataSync.

Answer

Create EBS snapshots of the HANA data and log volumes on a regular schedule.

Question 7

A company is running SAP NetWeaver on AWS with the database on Amazon EC2. The company needs to implement a disaster recovery (DR) solution with an RPO of 15 minutes and an RTO of 2 hours. The primary site is in us-east-1, and the DR site will be in us-west-2. The solution must be cost-effective. Which approach meets these requirements?

Accepted Answer

Use SAP HANA System Replication in asynchronous mode to a standby HANA database in us-west-2, and use AWS Elastic Disaster Recovery (DRS) for the application servers. Use a smaller, cost-effective instance for the standby that meets minimum SAP requirements.. SAP HANA System Replication in asynchronous mode provides continuous replication with an RPO that can be under 15 minutes. The standby database can run on a smaller instance that meets SAP minimum requirements for DR, reducing costs. AWS Elastic Disaster Recovery (DRS) replicates application servers with minimal overhead. Together, they meet the RPO and RTO cost-effectively.

Answer

Use SAP HANA System Replication in asynchronous mode to a standby HANA database in us-west-2, and use AWS Elastic Disaster Recovery (DRS) for the application servers. Configure the standby to be in a stopped state when not in use.

Answer

Use SAP HANA System Replication in asynchronous mode to a standby HANA database in us-west-2, and replicate the application servers using AWS Elastic Disaster Recovery (DRS).

Answer

Take hourly Amazon EBS snapshots of the HANA database and application servers, and copy them to us-west-2. In a disaster, restore from snapshots.

Question 8

A company runs SAP S/4HANA on AWS with the application servers on Amazon EC2 instances and the database on an Amazon RDS for SAP HANA instance. To reduce latency for the SAP application servers, they want to use Amazon Route 53 for DNS resolution. Which configuration should they use to ensure that the application servers resolve the database endpoint to the lowest-latency endpoint?

Accepted Answer

Create a Route 53 private hosted zone with a multivalue answer routing policy that includes the primary and read replica endpoints.. A private hosted zone with multivalue answer routing allows multiple IP addresses to be returned for a single DNS name, and health checks can be applied to each record. This is suitable for RDS endpoints because it can include the primary and read replicas, and the client can choose the lowest-latency endpoint if it supports it. It also provides basic load balancing and failover.

Answer

Create a Route 53 private hosted zone with a latency-based routing policy for the database endpoint.

Answer

Create a Route 53 private hosted zone with a simple routing policy that points to the RDS endpoint.

Answer

Create a Route 53 private hosted zone with a failover routing policy that points to the primary and standby RDS instances.

Question 10

An SAP HANA database runs on an Amazon EC2 X1 instance with 2 TB of memory. The database is currently using a single 3 TB gp2 EBS volume for /hana/data. Performance monitoring shows that the volume's burst balance is frequently depleted, causing latency spikes. The company wants to improve and stabilize storage performance. Which action should a SAP specialist take?

Accepted Answer

Replace the gp2 volume with a gp3 volume of the same size and provision additional IOPS and throughput.. gp3 volumes offer predictable baseline performance and allow independent scaling of IOPS and throughput without relying on burst credits. This directly addresses the burst depletion and latency spikes. Other options either do not apply, add unnecessary cost, or introduce complexity and risk. gp3 is the recommended EBS volume type for SAP HANA data and log volumes on AWS.

Answer

Create a RAID 0 array using multiple smaller gp2 volumes to increase aggregate IOPS and throughput.

Answer

Convert the volume to io1 with the same size and provision 10,000 IOPS.

Answer

Enable EBS Multi-Attach on the existing gp2 volume to allow multiple instances to share the I/O load.

Question 11

A company is running an SAP HANA database on an Amazon EC2 instance. The company needs to ensure that the database can be recovered to a specific point in time within the last 7 days. The company wants to use AWS native services and minimize administrative effort. What should the company do?

Accepted Answer

Configure SAP HANA backup to Amazon S3 with log backups and use SAP HANA recovery tools.. SAP HANA natively supports backup to Amazon S3, including data and log backups. By configuring log backups, you enable point-in-time recovery to any point within the retention period, such as the last 7 days. This method uses SAP HANA's recovery tools and requires minimal administrative effort because it is integrated into the database. Other options like EBS snapshots or AWS Backup do not provide transaction-level recovery for SAP HANA.

Answer

Enable automated backups for the EC2 instance and use Amazon EBS snapshots.

Answer

Enable Amazon RDS for SAP HANA and use its automated backups with point-in-time recovery.

Answer

Use AWS Backup to create a backup plan for the EC2 instance and enable continuous backup.

Question 12

A company is running SAP HANA on AWS with a scale-out configuration across multiple EC2 instances. The database is 5 TB and growing. The company needs to ensure that the HANA data and log volumes are backed up to Amazon S3 for long-term retention. The backup must be consistent across all nodes and must not impact the performance of the production database. Which backup strategy should be used?

Accepted Answer

Configure SAP HANA's backint API to use a certified third-party backup tool that supports Amazon S3, and schedule backups during off-peak hours.. Using a certified third-party backup tool via SAP HANA's backint API allows efficient, consistent backups to Amazon S3 across all nodes in a scale-out system. These tools are optimized for HANA and can schedule backups during off-peak hours, minimizing performance impact.

Answer

Use SAP HANA's built-in backup command to back up to an Amazon S3 bucket, scheduling full backups weekly and delta backups daily.

Answer

Use AWS Backup to create application-consistent backups of the HANA data and log volumes, with a backup plan that includes all EC2 instances in the scale-out configuration.

Question 13

A company runs SAP S/4HANA on a single AWS Availability Zone using an EC2 instance with an EBS volume. They want to minimize recovery time after an AZ failure and are evaluating AWS services. The RTO is 15 minutes and RPO is 5 minutes. Which solution should they implement to meet these objectives?

Accepted Answer

Configure SAP HANA system replication to a secondary EC2 instance in another AZ with synchronous mode, and use an Application Load Balancer to redirect traffic.. SAP HANA system replication with synchronous mode across Availability Zones provides a low RPO (zero data loss) and quick failover, satisfying the 15-minute RTO and 5-minute RPO. Other options either do not meet the RTO or are not designed for continuous database replication. The correct solution leverages native SAP HANA high availability capabilities on AWS.

Answer

Schedule AWS Backup to take snapshots of the EBS volume every 5 minutes and restore from the latest snapshot in another AZ.

Answer

Deploy SAP HANA on an EC2 instance in a spread placement group across multiple AZs to ensure automatic failover.

Answer

Use Amazon S3 Cross-Region Replication to replicate SAP HANA data files continuously and rebuild the database on failure.

Question 14

A company is deploying SAP HANA on AWS using a scale-up architecture with an Amazon EC2 instance. They need to ensure that the HANA database can be recovered to a point in time within the last 15 minutes in case of a disaster. The database size is 2 TB, and the change rate is high. Which backup strategy should they implement to meet the recovery point objective (RPO) of 15 minutes?

Accepted Answer

Perform full backups daily to Amazon S3 and enable automatic log backups every 15 minutes to Amazon S3.. SAP HANA automatic log backups capture the transaction log at regular intervals, enabling point-in-time recovery. Configuring log backups every 15 minutes to Amazon S3 ensures that in a disaster, the database can be recovered to within 15 minutes of the failure. Daily full backups provide the base backup. This is the standard method to achieve a low RPO.
