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.

質問 56
You plan to migrate an SAP environment to Azure.
You need to recommend a solution to migrate the SAP application servers to Azure. The solution must minimize downtime and changes to the environments.
What should you include in the recommendation?
- A. Azure Storage Explorer
- B. Azure Site Recovery
- C. Azure Import/Export service
- D. AzCopy
正解: B
解説:
Site Recovery is used to manage and orchestrate disaster recovery of on-premises machines and Azure VMs.
However, it can also be used for migration. Migration uses the same steps as disaster recovery with one exception. In a migration, failing machines over from your on-premises site is the final step. Unlike disaster recovery, you can't fail back to on-premises in a migration scenario.

質問 57
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. disk I/O during Enqueue backup operations
- B. misconfigured load balancer rules and health check probes for Enqueue and ASCS
- C. network latency between the database server and the SAP application servers
- D. a missing Enqueue profile
- E. active Enqueue replication
正解: B,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.

- B. Create a storage account
- C. Create a user-assigned managed identity
- D. Create an application registration in Azure AD.
正解: D
質問 59

- B. Use the Database Migration Option (DMO) to migrate to SAP HANA and Azure during the same maintenance window.
- C. Use Near-Zero Downtime (NZDT) to migrate to SAP HANA and Azure during the same maintenance window.
- D. Migrate SAP ECC to SAP Business Suite in HANA, and then migrate SAP to Azure.
正解: B
解説:
The SAP Database Migration Option (DMO) with System Move option of SUM, used as part of the migration allows customer the options to perform the migration in a single step, from source system on-premises, or to the target system residing in Microsoft Azure, minimizing overall downtime.

Overview
Contoso, Ltd. is a manufacturing company that has 15,000 employees.
The company uses SAP for sales and manufacturing.
Contoso has sales offices in New York and London and manufacturing facilities in Boston and Seattle.
Existing Environment
Active Directory
The network contains an on-premises Active Directory domain named ad.contoso.com. User email addresses use a domain name of contoso.com.
SAP Environment
The current SAP environment contains the following components:
* SAP Solution Manager
* SAP ERP Central Component (SAP ECC)
* SAP Supply Chain Management (SAP SCM)
* SAP application servers that run Windows Server 2008 R2
* SAP HANA database servers that run SUSE Linux Enterprise Server 12 (SLES 12) Problem Statements Contoso identifies the following issues in its current environment:
* The SAP HANA environment lacks adequate resources.
* The Windows servers are nearing the end of support.
* The datacenters are at maximum capacity.
Requirements
Planned Changes
Contoso identifies the following planned changes:
* Deploy Azure Virtual WAN.
* Migrate the application servers to Windows Server 2016.
* Deploy ExpressRoute connections to all of the offices and manufacturing facilities.
* Deploy SAP landscapes to Azure for development, quality assurance, and production.
All resources for the production landscape will be in a resource group named SAPProduction.
Business goals
Contoso identifies the following business goals:
* Minimize costs whenever possible.
* Migrate SAP to Azure without causing downtime.
* Ensure that all SAP deployments to Azure are supported by SAP.
* Ensure that all the production databases can withstand the failure of an Azure region.
* Ensure that all the production application servers can restore daily backups from the last 21 days.
Technical Requirements
Contoso identifies the following technical requirements:
* Inspect all web queries.
* Deploy an SAP HANA cluster to two datacenters.
* Minimize the bandwidth used for database synchronization.
* Use Active Directory accounts to administer Azure resources.
* Ensure that each production application server has four 1-TB data disks.
* Ensure that an application server can be restored from a backup created during the last five days within 15 minutes.
* Implement an approval process to ensure that an SAP administrator is notified before another administrator attempts to make changes to the Azure virtual machines that host SAP.
It is estimated that during the migration, the bandwidth required between Azure and the New York office will be
1 Gbps. After the migration, a traffic burst of up to 3 Gbps will occur.
Proposed Backup Policy
An Azure administrator proposes the backup policy shown in the following exhibit.
Azure Resource Manager Template
An Azure administrator provides you with the Azure Resource Manager template that will be used to provision the production application servers.
Migrate SAP Workloads to Azure
Question Set 3
質問 60
You have an on-premises SAP environment.
Backups are performed by using tape backups. There are 50 TB of backups.
