Question #31
HOTSPOT -
You are deploying an SAP environment across Azure Availability Zones. The environment has the following components:
✑ ASCS/ERS instances that use a failover cluster
✑ SAP application servers across the Azure Availability Zones
✑ Database high availability by using a native database solution
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:


Correct Answer:

 Box 1: No -
Azure Availability Zones are physically separate locations within an Azure region protecting customers' applications and data from datacenter-level failures. It is good for applications that require low-latency synchronous replication with protection from datacenter-level failures.

Box 2: Yes -
AAP application server to database server latency can be tested with ABAPMeter report /SSA/CAT.

Box 3: Yes -
To analyze network issue or measure network metrics you can test the connection using SAP's NIPING program. You can use NIPING to analyze the network connection between any two machines running SAP software.

Question #32
You deploy an SAP environment on Azure.
You need to validate the load distribution to the application servers.
What should you use?
  1. A
    SAPControl
  2. B
    SAP Solution Manager
  3. C
    Azure Monitor
  4. D
    SAP Web Dispatcher

Correct Answer:
D
Load balancers. These are used to distribute traffic to virtual machines in the application-tier subnet. For high availability, use the built-in SAP Web Dispatcher,
Azure Load Balancer, or network appliances, depending on the traffic type (such as HTTP or SAPGUI) or the required network services, such as Secure Sockets
Layer (SSL) termination.

Question #33
HOTSPOT -
You plan to deploy a highly available ASCS instance to SUSE Linux Enterprise Server (SLES) virtual machines in Azure.
You are configuring an internal Azure Standard Load Balancer for the ASCS instance.
How should you configure the internal Standard Load Balancer? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:


Correct Answer:

 Box 1: Client IP -
The standard load balancer allows stateful sessions to remain as there are no IP address changes with this method.

Box 2: Enabled -
Make sure to enable Floating IP.

Question #34
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
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. A
    Yes
  2. B
    No

Correct Answer:
A
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.

Question #35
HOTSPOT -
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:


Correct Answer:

 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 -

Question #36
You have an Azure subscription.
You deploy Active Directory domain controllers to Azure virtual machines.
You plan to deploy Azure for SAP workloads.
You plan to segregate the domain controllers from the SAP systems by using different virtual networks.
You need to recommend a solution to connect the virtual networks. The solution must minimize costs.
What should you recommend?
  1. A
    a site-to-site VPN
  2. B
    virtual network peering
  3. C
    user-defined routing
  4. D
    ExpressRoute

Correct Answer:
C
You can create custom, or user-defined, routes in Azure to override Azure's default system routes, or to add additional routes to a subnet's route table. In Azure, you create a route table, then associate the route table to zero or more virtual network subnets.
Incorrect Answers:
D: ExpressRoute is a costly solution.

Question #37
You deploy an SAP environment on Azure.
Your company has a Service Level Agreement (SLA) of 99.99% for SAP.
You implement Azure Availability Zones that have the following components:
✑ Redundant SAP application servers
✑ ASCS/ERS instances that use a failover cluster
Database high availability that has a primary instance and a secondary instance

You need to validate the high availability configuration of the ASCS/ERS cluster.
What should you use?
  1. A
    SAP Web Dispatcher
  2. B
    Azure Traffic Manager
  3. C
    SAPControl
  4. D
    SAP Solution Manager

Correct Answer: C ?️
