質問 121
You have an Azure subscription.
You plan to deploy an app that has a web front end and an application tier.
You need to recommend a load balancing solution that meets the following requirements:
* Internet to web tier:
- Provides URL-based routing
- Supports connection draining
- Prevents SQL injection attacks
* Web tier to application tier:
- Provides port forwarding
- Supports HTTPS health probes
- Supports an availability set as a backend pool
Which load balancing solution should you recommend for each tier? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

解説:
Explanation
Box 1: An Azure Application Gateway that has a web application firewall (WAF) Azure Application Gateway offers a web application firewall (WAF) that provides centralized protection of your web applications from common exploits and vulnerabilities. Web applications are increasingly targeted by malicious attacks that exploit commonly known vulnerabilities. SQL injection and cross-site scripting are among the most common attacks.
Application Gateway operates as an application delivery controller (ADC). It offers Secure Sockets Layer (SSL) termination, cookie-based session affinity, round-robin load distribution, content-based routing, ability to host multiple websites, and security enhancements.
Box 2: An internal Azure Standard Load Balancer
The internet to web tier is the public interface, while the web tier to application tier should be internal.
Note: When using load-balancing rules with Azure Load Balancer, you need to specify a health probes to allow Load Balancer to detect the backend endpoint status.
Health probes support the TCP, HTTP, HTTPS protocols.

Overview
The following section of the exam is a lab. In this section, you will perform a set of tasks in a live environment.
While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design.
Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.
Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.

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 have an app named App1 that uses data from two on-premises Microsoft SQL Server databases named DB1 and DB2.
You plan to move DB1 and DB2 to Azure.
You need to implement Azure services to host DB1 and DB2. The solution must support server-side transactions across DB1 and DB2.
Solution: You deploy DB1 and DB2 as Azure SQL databases on the same Azure SQL Database server.
Does this meet the goal?
- A. Yes
- B. No
正解: B
解説:
Explanation
Instead deploy DB1 and DB2 to SQL Server on an Azure virtual machine.
Note: Understanding distributed transactions.
When both the database management system and client are under the same ownership (e.g. when SQL Server is deployed to a virtual machine), transactions are available and the lock duration can be controlled.

You manage an Active Directory domain named contoso.local.
You install Azure AD Connect and connect to an Azure Active Directory (Azure AD) tenant named contoso.com without syncing any accounts.
You need to ensure that only users who have a UPN suffix of contoso.com in the contoso.local domain sync to Azure AD.
Solution: You use Azure AD Connect to customize the synchronization options.
Does this meet the goal?
- A. Yes
- B. No
正解: B
解説:
Section: [none]
Explanation:
Instead use Synchronization Rules Editor to create a synchronization rule.
Note: Filtering what objects are synced to Azure AD is a common request and there are many instances where filtering by OU just doesn't cut it. One option is to filter users by their UPN suffix so that only users with the public FQDN as their UPN suffix are synced to Azure AD (e.g., [email protected] would be synced while [email protected] would not).
Filtering can be configured using either the GUI (Synchronization Rules Editor) or PowerShell.
