質問 22
You plan to deploy an SAP environment on Azure that will use Azure Availability Zones.
Which load balancing solution supports the deployment?
- A. Azure Standard Load Balancer
- B. Azure Basic Load Balancer
- C. Azure Application Gateway v1 SKU
正解: A
解説:
Explanation
When you deploy Azure VMs across Availability Zones and establish failover solutions within the same Azure region, some restrictions apply:
* You can't use an Azure Basic Load Balancer to create failover cluster solutions based on Windows Server Failover Clustering or Linux Pacemaker. Instead, you need to use the Azure Standard Load Balancer SKU.

質問 25
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
正解:
解説:
Explanation:
In a Hybrid-IT scenario, Active Directory from on-premises can be extended to serve as the authentication mechanism through an Azure deployed domain controller (as well as potentially using the integrated DNS).
It is important to distinguish between traditional Active Directory Servers and Microsoft Azure Active Directory that provides only a subset of the traditional on-premises AD offering. This subset include Identity and Access Management, but does not have the full AD schema or services that many 3rd party application take advantage of. While Azure Active Directory IS a requirement to establish authentication for the Azure virtual machines in use, and it can synchronize users with customers' on-premises AD, the two are explicitly different and customers will likely continue to require full Active Directory servers deployed in Microsoft Azure.

Existing Environment
Infrastructure
Litware currently uses a third-party provider to host a datacenter in Miami and a disaster recovery datacenter in Chicago, IL.
The network contains an Active Directory domain named litware.com. Litware has two third-party applications hosted in Azure.
Litware already implemented a site-to-site VPN connection between the on-premises network and Azure.

* SAP Solution Manager
All servers run on the Windows Server platform. All databases use Microsoft SQL Server. Currently, you have
20 production servers.
You have 30 non-production servers including five testing servers, five development servers, five quality assurance (QA) servers, and 15 pre-production servers.
Currently, all SAP applications are in the litware.com domain.
Problem Statements
The current version of SAP ECC has a transaction that, when run in batches overnight, takes eight hours to complete. You confirm that upgrading to SAP Business Suite on HANA will improve performance because of code changes and the SAP HANA database platform.
Litware is dissatisfied with the performance of its current hosted infrastructure vendor. Litware experienced several hardware failures and the vendor struggled to adequately support its 24/7 business operations.
Requirements
Business Goals
Litware identifies the following business goals:
* Increase the performance of SAP ECC applications by moving to SAP HANA. All other SAP databases will remain on SQL Server.
* Move away from the current infrastructure vendor to increase the stability and availability of the SAP services.
* Use the new Environment, Health and Safety (EH&S) in Recipe Management function.
* Ensure that any migration activities can be completed within a 48-hour period during a weekend.
Planned Changes
Litware identifies the following planned changes:
* Migrate SAP to Azure.
* Upgrade and migrate SAP ECC to SAP Business Suite on HANA Enhancement Pack 8.
Technical Requirements
Litware identifies the following technical requirements:
* Implement automated backups.
* Support load testing during the migration.
* Identify opportunities to reduce costs during the migration.
* Continue to use the litware.com domain for all SAP landscapes.
* Ensure that all SAP applications and databases are highly available.
* Establish an automated monitoring solution to avoid unplanned outages.
* Remove all SAP components from the on-premises network once the migration is complete.
* Minimize the purchase of additional SAP licenses. SAP HANA licenses were already purchased.
* Ensure that SAP can provide technical support for all the SAP landscapes deployed to Azure.

質問 30
You are migrating SAP to Azure. The ASCS application servers are in one Azure zone, and the SAP database server in in a different Azure zone. ASCS/ERS is configured for high availability.
During performance testing, you discover increased response times in Azure, even though the Azure environment has better computer and memory configurations than the on-premises environment.
During the initial analysis, you discover an increased wait time for Enqueue.
What are three possible causes of the increased wait time? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A. active Enqueue replication
- B. a missing Enqueue profile
- C. misconfigured load balancer rules and health check probes for Enqueue and ASCS
- D. disk I/O during Enqueue backup operations
- E. network latency between the database server and the SAP application servers
正解: A,C,E
解説:
E: The network latency across Availability Zones is not the same in all Azure regions. In some cases, you can deploy and run the SAP application layer across different zones because the network latency from one zone to the active DBMS VM is acceptable. But in some Azure regions, the latency between the active DBMS VM and the SAP application instance, when deployed in different zones, might not be acceptable for SAP business processes.

質問 31
You are deploying an SAP environment on Azure that will use an SAP HANA database server.
You provision an Azure virtual machine for SAP HANA by using the M64s virtual machine SKU.
You need to set the swap space by using the Microsoft Azure Linux Agent (waagent) configuration file.
Which two settings should you configure? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. ResourceDisk.SwapSizeMB=229376
- B. ResourceDisk.EnableSwap=y
- C. ResourceDisk.EnableSwapEncryption=n
- D. AutoUpdate.Enabled=n
正解: A,B
解説:
To create a swap file in the directory that's defined by the ResourceDisk.MountPoint parameter, you can update the /etc/waagent.conf file by setting the following three parameters:
ResourceDisk.Format=y
ResourceDisk.EnableSwap=y
ResourceDisk.SwapSizeMB=xx

質問 33
Your on-premises network contains SAP and non-SAP applications.
You have JAVA-based SAP systems that use SPNEGO for single-sign on (SSO) authentication.
Your external portal uses multi-factor authentication (MFA) to authenticate users.
You plan to extend the on-premises authentication features to Azure and to migrate the SAP applications to Azure.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
正解:
解説:
Explanation:
Box 1: No
Need AD FS for MF
Note: Azure Active Directory (Azure AD) Pass-through Authentication allows your users to sign in to both on-premises and cloud-based applications using the same passwords. This feature is an alternative to Azure AD Password Hash Synchronization (see Box 2).
Box 2: Yes
Password hash synchronization is one of the sign-in methods used to accomplish hybrid identity. Azure AD Connect synchronizes a hash, of the hash, of a users password from an on-premises Active Directory instance to a cloud-based Azure AD instance.
Password hash synchronization is an extension to the directory synchronization feature implemented by Azure AD Connect sync. You can use this feature to sign in to Azure AD services like Office 365. You sign in to the service by using the same password you use to sign in to your on-premises Active Directory instance.
Box 3: Yes
If your organization is federated with Azure AD, you can use Azure Multi-Factor Authentication to secure AD FS resources, both on-premises and in the cloud. Azure MFA enables you to eliminate passwords and provide a more secure way to authenticate.
