You are implementing a software as a service (SaaS) ASP.NET Core web service that will run as an Azure Web App. The web service will use an on-premises SQL Server database for storage. The web service also includes a WebJob that processes data updates. Four customers will use the web service.
✑ Each instance of the WebJob processes data for a single customer and must run as a singleton instance.
✑ Each deployment must be tested by using deployment slots prior to serving
production data.
✑ Azure costs must be minimized.
✑ Azure resources must be located in an isolated network.
You need to configure the App Service plan for the Web App.
How should you configure the App Service plan? To answer, select the appropriate settings in the answer area.
NOTE:Each correct selection is worth one point.

Solution:
Number of VM instances: 4
You are not charged extra for deployment slots.
Pricing tier: Isolated
The App Service Environment (ASE) is a powerful feature offering of the Azure App Service that gives network isolation and improved scale capabilities. It is essentially a deployment of the Azure App Service into a subnet of a customer’s Azure Virtual Network (VNet).

You must test the app to ensure that the app is available and responsive from various points around the world and at regular intervals. If the app is not responding, you must send an alert to support staff.
You need to configure a test for the web app.
Which two test types can you use? Each correct answer presents a complete solution.
NOTE:Each correct selection is worth one point.

1. A. integration

Correct Answer: BC
There are three types of availability tests:
✑ URL ping test: a simple test that you can create in the Azure portal.
✑ Multi-step web test: A recording of a sequence of web requests, which can be played back to test more complex scenarios. Multi-step web tests are created in Visual Studio Enterprise and uploaded to the portal for execution.
✑ Custom Track Availability Tests: If you decide to create a custom application to run availability tests, the TrackAvailability() method can be used to send the results to Application Insights.

You use Azure Table storage to store customer information for an application. The data contains customer details and is partitioned by last name. You need to create a query that returns all customers with the last name Smith. Which code segment should you use?

1. A. TableQuery.GenerateFilterCondition("PartitionKey", Equals, "Smith")
2. B. TableQuery.GenerateFilterCondition("LastName", Equals, "Smith")
3. C. TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith")
4. D. TableQuery.GenerateFilterCondition("LastName", QueryComparisons.Equal, "Smith")

Correct Answer: C
Retrieve all entities in a partition. The following code example specifies a filter for entities where 'Smith' is the partition key. This example prints the fields of each entity in the query results to the console.
Construct the query operation for all customer entities where PartitionKey="Smith".
TableQuery query = new TableQuery().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith"));
