NEW QUESTION 15
DRAG DROP
You are developing a web application by using Microsoft ASP.NET MVC.
The web application will show a list of cars and their associated prices. The list can be filtered by car model by using a drop-down list. Access to the web application will be anonymous.
The car model list is stored as an .xml file on the application server. The car prices list is stored on a SQL Server server.
You need to recommend a caching strategy for each scenario:
If a user selects a car model from the drop-down list, and then closes the browser, the same
model must be selected automatically when the user reopens the web application from the same browser.
If the car model list is updated, the drop-down list must be refreshed upon the next page reload.
If the car prices list is updated, the prices list must be refreshed upon the next page reload.
What should you recommend? To answer, drag the appropriate caching strategies to the correct scenarios. Each caching strategy may be used once, more than once, or not at all. You
may need to drag the split bar between panes or scroll to view content.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Box 1: outputCache
outputCache declaratively controls the output caching policies of an ASP.NET page or a user control contained in a page.
Box 2: CacheDependency
CacheDependency establishes a dependency relationship between an item stored in an ASP.NET application's Cache object and a file, cache key, an array of either, or another CacheDependency object. The CacheDependency class monitors the dependency relationships so that when any of them changes, the cached item will be automatically removed.
Box 3: SqlCacheDependency
SQL cache dependency enables you to cache pages that are dependent on data from SQL Server tables. You can configure SQL Server and ASP.NET tocache page requests, reducing server workload, until the data on which the page depends has been updated in SQL Server. SQL cache dependency is useful for data such as product catalogs or customer registration information that remains comparatively static.

You plan to use Application Insights for collecting telemetry dat a.
You must prepare a report that describes utilization patterns of uses. The report must include the following information:
the Country or Region from which users access the application
how often and for how long users browse the catalog
how many Canadian customers visited the offers page
how much time Premium customers spend on the support page
the percentage of users that added items to a shopping cart and completed purchases
You need to collect the required data.
Which tool should you use? To answer, drag the appropriate tools to the correct requirements. Each tool may be used once, more than once, or mot at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Box 1 Geography: Users
"the Country or Region from which users access the application"
The Users panel allows you to understand important details about your users in a variety of ways. You can use this panel to understand such information as where your users are connecting from, details of their client, and what areas of your application they're accessing.
Box 2: Feature usage: Session
" how often and for how long users browse the catalog"
The Sessions panel is similar to the Users panel. Where Users helps you understand details about the users accessing your application, Sessions helps you understand how those users used your application.
Box 3 Canada Offers: Cohorts
" how many Canadian customers visited the offers page"
A Cohort is a set of users grouped on similar characteristics. You can use cohorts to filter data in other panels allowing you to analyze particular groups of users. For example, you might want to analyze only users who completed a purchase, or users from Canada.
Box 4 Premium support: Cohorts
"how much time Premium customers spend on the support page"
A Cohort is a set of users grouped on similar characteristics. You can use cohorts to filter data in other panels allowing you to analyze particular groups of users. For example, you might want to analyze only users who completed a purchase, or users from Canada.
Box 5: Buyer behavior: Funnels
"the percentage of users that added items to a shopping cart and completed purchases" Funnels focus on what you want users to do. A funnel represents a set of steps in your
application and the percentage of users who move between steps. For example, you could create a funnel that measures the percentage of users who connect to your application who search product. You can then see the percentage of users who add that product to a shopping cart, and then the percentage of those who complete a purchase.

Trey Research Inc
Overview
Trey Research Inc. is a Software-as-a-Service (SaaS) company that provides hosted solutions for business partners around the world. The company is developing a solution that will allow business partners to manage events, including shareholder meetings and trade shows.
You hold meetings with key partners to identify requirements and constraints for the solution. You must minimize costs where possible.
You work with an Azure solutions architect to design the logical structure for the solution. The solution will use the following architecture:

Solution components
The solution will use Azure Traffic Manager to distribute traffic. The solution will use API Management to provide caching for the Event Service. Partner companies will interact with the solution by using the Event Service API. This API will be implemented as an ASP.NET Core Web API that runs as an Azure Web App. Event data will be stored in Cosmos DB using the Document API.
The solution will be highly available. You define regional Azure outages as periods of 60 seconds or more where the Event Service is not available.
An Azure WebJob named EventJob will be deployed with the Event Service Web App. The WebJob:
Creates new computed events when partner events are created.
Must be active whenever the Event Service is running.
Is updated once a quarter.
Trey Research Inc. has developer teams that work with a variety of operating systems including Windows, Linux, and MacOS.
Event Service
Individual events must be immutable. Event data can be up to 800 kilobytes (KB) in size. The Event Service must meet the following requirements:
Use REST-based design
Cache data whenever possible.
Support both JSON and XML-based data.
Log customer information whenever data is modified.
Include the X-Customer header in all calls to identify the partner. Regional access to the Event Service API
Data for partners in Germany and Brazil must be served from Azure datacenters in their respective geographies unless there is a regional Azure outage. All other partners must use the US West Azure datacenter.
Testing
All testing must interact directly with the Web App backend. Automated testing of the solution is performed using a remote third-party testing solution.
Event data
You identify the following requirements for the event data store:
Each partner’s event data must be stored in a Collection that is specific to the partner.
Event data must be available if a regional Azure outage occurs.
Event read and write operations for a single partner must always store events in the correct order.
Event API
Relevant portions of the app files are shown below. Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.
