Online Bookstore
Background
You are developing an online bookstore web application that will be used by your company's customers.
Technical Requirements
General requirements:
✑ The web store application must be an ASP.NET MVC application written in Visual Studio.
✑ The application must connect to a Microsoft SQL database.
✑ The GetTop100Books() method is mission critical and must return data as quickly as possible. It should take advantage of fast, forward-only, read-only methods of reading data.
✑ The ImportBooks() method must keep a copy of the data that can be accessed while new books are being imported without blocking reads.
✑ The Create MonthlyTotalsReport() method must lock the data and prevent others from updating or inserting new rows until complete.
✑ The college textbook area of the web application must get data from a daily updated CSV file.
✑ The children's book area of the web application must get data directly from a local database. It must use a connection string. It must also support access to the stored procedures on the database. Further, it is required to have strongly typed objects. Finally, it will require access to databases from multiple vendors and needs to support more than one-to-one mapping of database tables.
✑ The cookbook functionality is contained within a client-side application that must connect to the server using HTTP and requires access to the data using JavaScript.
✑ The BookApiController class must have a method that is able to perform ad-hoc queries using OData.
The RESTful API of the bookstore must expose the following endpoints.

Application Structure



PurchaseOrders.xml

FeaturedBooks.xml

You need to configure settings to identify regional outages.
Which values should you use? To answer, drag the appropriate values to the correct settings. Each value 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.

Answer:

Explanation: Box 1, Probing interval: 10
Probing Interval. This value specifies how often an endpoint is checked for its health from a Traffic Manager probing agent. You can specify two values here: 30 seconds (normal probing)
and 10 seconds (fast probing). If no values are provided, the profile sets to a default value of 30 seconds.
Box 2: Tolerated Number of Failures: 3
Tolerated Number of Failures. This value specifies how many failures a Traffic Manager probing agent tolerates before marking that endpoint as unhealthy. Its value can range between 0 and 9. A value of 0 means a single monitoring failure can cause that endpoint to be marked as unhealthy. If no value is specified, it uses the default value of 3.
Scenario: 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.
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.

NEW QUESTION 13
HOTSPOT
You updating an existing multitenant ASP.NET MVC application for medical clinics. The application aggressively uses output caching to improve performance by caching content for 36 hours. The application uses a query string parameter named “clinicID” that contains the clinic that the user is currently viewing.
Users report that they are occasionally seeing data for the wrong clinic. Users also report that the application seems to take a long time to return data for a specific clinic even if they have viewed it recently.
You need to configure web.config to resolve the reported problems.
You have the following markup:

Which markup segments should you include in Target 1, Target 2 and Target 3 to complete the markup? (To answer, select the correct markup segment from each drop-down list in the answer area.)

Answer:

Explanation: Target 1: noStore="false"
The page that has the OutputCacheProfile.NoStore property set to true issues a response specifying in its header to prevent secondary storage of sensitive information.
Target 2: VaryByParam ="clinicID"
The VaryByParam is a semicolon-delimited set of parameters used to vary the cached output. It allows varying the cached output by GET query string or form POST parameters. For instance, you can vary the user-control output to the cache by specifying the user- control name along with either a query string or a form POST parameter.
Incorrect: Not varyByControl="ClinicID"
The VaryByControl is a semicolon-delimited set of IDs of controls to be cached. Target 3: duration=129600"
The Duration represents the time in seconds that the page or user control is cached. Setting this property establishes an expiration policy for HTTP responses from the page or control to which it applies and will automatically cause the caching of their output.
129600 seconds is 36 hours (60*60*36).
