Free Microsoft AZ-120 Exam Questions

You have an on-premises SAP AnyDB deployment hosted on an operating system that is NOT supported in Azure.

You need to migrate the deployment to Azure by performing a replatform and migration to SAP HANA. The solution must meet the following requirements:

Minimize administrative effort.

Minimize downtime.

What should you use?

  1. Azure Migrate
  2. Azure Database Migration Service
  3. SAP Software Provisioning Manager
  4. SAP Software Update Manager

Answer(s): D

Explanation:

Migrate an SAP platform to Azure
DMO: DMO uses one tool to upgrade an SAP workload and a database migration to the SAP HANA database, and this process is often called a one-step migration. The SAP Software Update Manager tool creates a shadow repository for the current database while creating a target database simultaneously. It eventually copies the shadow repository and switches the SAP database connection to the target database. This approach is commonly used when the following data points are observed in the migration plan:
The current OS or DBMS isn't supported in Azure, requiring an upgrade or replatform.
*-> There's a plan to upgrade to SAP S/4HANA during migration.
Note: Software Update Manager
The Software Update Manager (SUM) can be used for several scenarios or use cases.
Database Migration
A database migration transfers the SAP system from one database type to another. The Software Update Manager offers the Database Migration Option (DMO), which is the combination of the SAP software update with the database migration.
DMO was initially a procedure to migrate to an SAP HANA database only. At this time, only the combination of upgrade and migration was possible, since typically the source system was not yet on a software level that is
supported by SAP HANA database. Now, DMO allows for migration to other database types than SAP HANA database (see respective SAP note for details and restrictions) and DMO can be used for a pure migration, without changing the SAP software level: DMO without System Change. In addition, it is possible to change not only the database (host), but also the Application Server: DMO with System Move.
Incorrect:
* Azure Migrate
Azure Migrate features tools that can migrate most platforms and workloads, but SAP workloads require different tools and processes to replicate and deploy their assets. Once the core platform is deployed, standard processes and tools help dependent workloads to resume and finish migrating.
Note: Azure Migrate is a Microsoft service that helps an enterprise assess how its on-premises workloads will perform, and how much they will cost to host, in the Azure public cloud.
An enterprise can use Azure Migrate to discover information about the VMware VMs running within its own data center, including CPU and memory usage, as well as performance history.
* Azure Database Migration Service
Azure Database Migration Service enables seamless migrations from multiple database sources to Azure Data platforms with minimal downtime. The service uses the Data Migration Assistant to generate assessment reports that provide recommendations to guide you through the changes required before performing a migration. When you're ready to begin the migration process, Azure Database Migration Service performs all the required steps.
* SAP Software Provisioning Manager
Software Provisioning Manager offers the execution of many system provisioning tasks and covers a broad range of platforms and products, both on the ABAP and the Java technology.
Classical migration: The SAP Software Provisioning Manager is a software logistics tool for database migrations. Classical migration uses a homogeneous or heterogenous system copy approach, sometimes called a two-step migration. This approach is commonly used when the following observations surface in the migration plan:
The operating systems (OS) and DBMS are compatible with Azure.
There aren't other requirements to upgrade or replatform the OS or DBMS systems.

Answer(s): A

Explanation:



Box 1: RMAN
To export the Oracle database

Azure Virtual Machines Oracle DBMS deployment for SAP workload Scenario: huge data and data change volumes more than 5 TB, restore time crucial Customer has a huge database where backup and/or restore + recovery of a single database can't be accomplished in a timely fashion.

Usually customers are using RMAN, Azure Backup for Oracle and/or disk snap techniques in combination. In this variant, each relevant database file type is separated to different Oracle ASM disk groups.

Box 2: R3load
To transfer the database files to Azure before the import

Very Large Database Migration to Azure Recommendations & Guidance to Partners

Your on-premises network contains the following:

A 1-Gbps internet connection

An SAP HANA 1.0 instance that has a 4-TB database

An SAP landscape that uses SUSE Linux Enterprise (SLES) 12

You have an Azure subscription that contains a virtual machine. The virtual machine is of the M64s SKU and runs SLES 15 and HANA 2.0.

You need to migrate the database to the virtual machine and upgrade the database to HANA 2.0. The solution must meet the following requirements:

The migration must be performed during a weekend.


The database can be offline during the migration.

Which migration method should you use?

  1. Azure Data Box
  2. HANA database backup and log shipping
  3. Azure Migrate
  4. HANA database export and import

Answer(s): D

Explanation:

SAP HANA Migration
Homogeneous System Copy
This involves moving or copying a SAP system to a new environment, given that:
The source system and target system use the same operating system and database.
The hardware architecture remains unchanged, or the target system is SAP-certified for homogeneous system copy.
You can use a variety of methods for homogeneous system copy:
*-> Using SAP migration tools for database export and import.
Using standard backup tools supported by the database to backup the database and recover it to the new location.
Using hardware-based migration tools to clone the database to the new location Virtual machine (VM) copying.
Heterogeneous System Copy
This involves moving or copying an SAP system to a new environment, given that:
The source system and target system use different operating systems and/or databases There may be a hardware architecture change
Incorrect:
* Azure Data Box
Azure Data Box is just for the data transfer, not for actually upgrading the system.
Azure Data Box is not needed in this scenario.
Azure Data Box is a physical data transfer device offered by Microsoft Azure. It is designed to help users securely move large volumes of data into and out of Azure. The device can store up to 80 TB and transfer up to 1 PB of data, and it comes in several different models, including Data Box, Data Box Disk, and Data Box Heavy. Data can be transferred using the device's high-speed network connections, and it also features security measures such as encryption and tracking.

You have an Azure subscription and an Enterprise Agreement (EA).

You plan to deploy an SAP on Azure production landscape that will contain the following virtual machines:

One M-series virtual machine with 128 cores

15 E-series virtual machines with a total of 300 cores

10 D-series virtual machines with a total of 160 cores


During the deployment of the E-series virtual machines, you receive the following error message.
Operation results in exceeding quota limits of Core.

You need to ensure you can complete the E-series virtual machine deployment. The solution must meet the

following requirements:

Maintain the performance of the SAP landscape.

Minimize administrative effort.

Minimize costs.

What should you do?

  1. Convert the subscription to Pay-As-You-Go (PAYG).
  2. Create a second subscription and split the virtual machines evenly between both subscriptions.
  3. Resize the D-series and E-series virtual machines.
  4. Request a quota increase for the Azure region.

Answer(s): D

Explanation:

Save costs with Azure Reserved VM Instances
Purchase restriction considerations
Reserved VM Instances are available for most VM sizes with some exceptions. Reservation discounts don't apply for the following VMs:
* Insufficient quota - A reservation that is scoped to a single subscription must have vCPU quota available in the subscription for the new RI. For example, if the target subscription has a quota limit of 10 vCPUs for D- Series, then you can't buy a reservation for 11 Standard_D1 instances. The quota check for reservations includes the VMs already deployed in the subscription. For example, if the subscription has a quota of 10 vCPUs for D-Series and has two standard_D1 instances deployed, then you can buy a reservation for 10 standard_D1 instances in this subscription. You can create *quote increase request* to resolve this issue.
* Etc.
Note: Increase regional vCPU quotas
You can request regional vCPU quota increases for all VMs in a given region. You can also request increases for VM-family vCPU quotas or spot vCPU quotas.

You have a deployment of SAP NetWeaver on Azure that contains a virtual machine named VM1.

You need to configure the Linux OS provider for Azure Monitor for SAP solutions on VM1.

What should you do first?

  1. Enable TLS 1.2 for telemetry data in transit in Azure Monitor for SAP solutions.
  2. Install performance co-pilot (PCP) on VM1.
  3. Enable Insights in Azure Monitor for SAP solutions.
  4. Install the node exporter on VM1.

Answer(s): D

Explanation:

Configure Linux provider for Azure Monitor for SAP solutions Prerequisites

An Azure subscription.
An existing Azure Monitor for SAP solutions resource.
*-> Install the node exporter latest version in each SAP host that you want to monitor, either BareMetal or Azure virtual machine (VM).
Node exporter uses the default port 9100 to expose the metrics. If you want to use a custom port, make sure to open the port in the firewall and use the same port while creating the provider.
Default port 9100 or custom port that will be configured for node exporter should be open and listening on the Linux host.

You have an Azure subscription. The subscription contains a virtual machine named VM1 that runs SUSE Linux Enterprise Server (SLES) and was created by using an Azure Marketplace image.

You plan to deploy four virtual machines based on VM1 that will have the SAP Web Dispatcher role.

You need to create a generalized image of VM1.

What should you do first?

  1. Install the Custom Script Extension.
  2. Run sysprep.
  3. Install the Azure Linux VM agent.
  4. Run waagent.

Answer(s): D

Explanation:

* The SAP Web dispatcher lies between the Internet and your SAP system. It is the entry point for HTTP(s) requests into your system, which consists of one or more NetWeaver application servers.
* What is the Azure Linux Agent?
The Microsoft Azure Linux Agent (waagent) manages both Linux & FreeBSD provisioning, and virtual machine (VM) interaction with the Azure Fabric Controller. Besides the Linux Agent providing provisioning functionality, Azure also provides the option of using cloud-init for some Linux operating systems.
* High availability for SAP NetWeaver on Azure VMs on SUSE Linux Enterprise Server for SAP applications SAP NetWeaver application server preparation
Some databases require that the database instance installation is executed on an application server. Prepare the application server virtual machines to be able to use them in these cases.
The steps bellow assume that you install the application server on a server different from the ASCS/SCS and HANA servers. Otherwise some of the steps below (like configuring host name resolution) aren't needed.
1. Configure operating system
2. Set up host name resolution
3. Create the sapmnt directory
4. Configure autofs
5. Configure SWAP file
sudo vi /etc/waagent.conf
# Set the property ResourceDisk.EnableSwap to y
# Create and use swapfile on resource disk.
ResourceDisk.EnableSwap=y
# Set the size of the SWAP file with property ResourceDisk.SwapSizeMB # The free space of resource disk varies by virtual machine size. Make sure that you do not set a value that is too big. You can check the SWAP space with command swapon
# Size of the swapfile.
ResourceDisk.SwapSizeMB=2000
Restart the Agent to activate the change
sudo service waagent restart
