You deploy SAP HANA on Azure (Large Instances). You need to back up the SAP HANA database to Azure.

Solution: You create a Recovery Services vault and a backup policy. Does this meet the goal?

  1. Yes
  2. No

Answer(s): A

Explanation:

Backup architecture
The backup process begins by creating a Recovery services vault in Azure. This vault will be used to store the backups and recovery points created over time.
The Azure VM running SAP HANA server is registered with the vault, and the databases to be backed-up are discovered. To enable the Azure Backup service to discover databases, a preregistration script must be run on the HANA server as a root user.

This script creates AZUREWLBACKUPHANAUSER DB user and a corresponding key with the same name in hdbuserstore. Refer to the setting up permissions section to understand more about what the script does.

Azure Backup Service now installs the Azure Backup Plugin for HANA on the registered SAP HANA server. The AZUREWLBACKUPHANAUSER DB user created by the preregistration script is used by the Azure Backup Plugin for HANA to perform all backup and restore operations. If you attempt to configure backup for SAP HANA DBs without running this script, you might receive the following error: UserErrorHanaScriptNotRun.

To configure backup on the databases that are discovered, choose the required backup policy and enable backups.
Once the backup is configured, Azure Backup service sets up the Backint parameters at the DATABASE level on the protected SAP HANA server.

The Azure Backup Plugin for HANA maintains all the backup schedules and policy details. It triggers the scheduled backups and communicates with the HANA Backup Engine through the Backint APIs.
The HANA Backup Engine returns a Backint stream with the data to be backed up.

All the scheduled backups and on-demand backups (triggered from the Azure portal) that are either full or differential are initiated by the Azure Backup Plugin for HANA. However, log backups are managed and triggered by HANA Backup Engineitself.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: No
Box 2: Yes
The minimum SAP HANA certified conditions for the different storage types are:
Azure Premium SSD - /hana/log is required to be cached with Azure Write Accelerator. The /hana/data volume could be placed on Premium SSD without Azure Write Accelerator or on Ultra disk
Box 3: Yes

You have an SAP landscape on Azure that contains the virtual machines shown in the following table.
You need to ensure that the Application Server role is available if a single Azure datacenter fails. What should you include in the solution?

  1. a local network gateway
  2. Azure Load Balancer Standard
  3. Azure Virtual WAN
  4. Azure Active Directory (Azure AD) Application Proxy

Answer(s): B

Explanation:

For the load balancers of the failover clusters of SAP Central Services and the DBMS layer, you need to use the Standard SKU Azure Load Balancer. The Basic Load Balancer won't work across zones.
Note:
The DBMS also is a single point of contact in an SAP system. You need to protect it by using a high-availability solution. The following figure shows a SQL Server AlwaysOn high-availability solution in Azure, with Windows
Server Failover Clustering and the Azure internal load balancer.

Incorrect Answers:
C: Azure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface.
D: Application Proxy is recommended for giving remote users access to internal resources. Application Proxy replaces the need for a VPN or reverse proxy for these remote access use cases.
