You are developing an ASP.NET solution that consists of the following components:

You plan to use Microsoft Azure DevTest labs to create a testing environment. You create a virtual hard disk for the web front-end that includes all required components for the legacy applications.
The front-end application virtual machines must meet the following requirements:
Redeploy the virtual machines with the latest versions of build artifacts from the build system when they become available.
Isolate the virtual machines by using virtual networks.
You need to recommend an approach to deploy the virtual machines.
What should you recommend? To answer, drag the appropriate virtual machine deployment approaches in Azure DevTest to the correct targets. Each answer choice 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.
NOTE: Each correct selection is worth one point.

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 questions sets might have more than one correct solution, while others might not have a correct solution.

You are developing a collaborative text editor. Multiple users may simultaneously edit the same document from within the application.
You need to ensure that users can see edits from all users as soon as they are made.
Solution: Implement the application by using ASP.NET Core. Implement Websockets to handle the editor communication requirements.
Does the solution meet the goal?

• A. No
• B. Yes

You are developing an ASP.NET Core MVC web application.
You write a Gulp task to automatically minify and upload JavaScript CSS, and image files to Microsoft Azure CDN.
You need to ensure that the minification and upload tasks run automatically after every build in Microsoft Visual Studio Professional.
Which tool should you use?

• A. Visual Studio Batch Build dialog
• B. Task Runner Explorer After Build binding

• C. Bower Package manager
• D. Azure Publish Dialog's Connected Services section
• E. Visual Studio Build Continuous Delivery tool

You are developing an ASP.NET MVC application that will be hosted on Microsoft Azure. The application includes the StackExchange.Redis client package. A variable named CacheConnectionConfiguration stores the cache endpoint URL and the password to connect to the cache.
The application must store a user's color selection by using the Azure Redis cache. The cached value must expire after 90 minutes. You need to cache the user's color selection.
How should you complete the relevant code? To answer, choose the appropriate code segment from each list in the answer area.

Explanation:
Box 1: var cache = connection.GetDatabase():
Once the connection is established, return a reference to the redis cache database by calling the ConnectionMultiplexer.GetDatabase method.
Box 2: cache StringSet("color", colorSelection,TimeSpan.FromMinutes(90)); The TimeSpanFromMinutes method returns a TimeSpan that represents a specified number of minutes, where the specification is accurate to the nearest millisecond.
Example: The following code snippet shows how to set an expiration time of 90 minutes on a key.
// Add a key with an expiration time of 90 minutes
await cache.StringSetAsync("data:key1", 99, TimeSpan.FromMinutes(90));
