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.

A web service provides customer summary information for e-commerce partners. The web service is implemented as an Azure Function app with an HTTP trigger.
Access to the API is provided by an Azure API Management instance. The API Management instance is configured in consumption plan mode. All API calls are authenticated by using OAuth.
API calls must be cached. Customers must not be able to view cached data for other customers.
You need to configure API Management policies for caching.
How should you complete the policy statement?
Select and Place:
Answer:
Box 1: internal -
caching-type
Choose between the following values of the attribute:
✑ internal to use the built-in API Management cache,
✑ external to use the external cache as Azure Cache for Redis prefer-external to use external cache if configured or internal cache otherwise.
Box 2: private -
downstream-caching-type
This attribute must be set to one of the following values.
✑ none - downstream caching is not allowed.
✑ private - downstream private caching is allowed.
✑ public - private and shared downstream caching is allowed.
Box 3: Authorization -
<vary-by-header>Authorization</vary-by-header>
<!-- should be present when allow-private-response-caching is "true"-->
Note: Start caching responses per value of specified header, such as Accept, Accept-Charset, Accept-Encoding, Accept-Language, Authorization, Expect, From,
Host, If-Match -

You are developing applications for a company. You plan to host the applications on Azure App Services.
The company has the following requirements:
✑ Every five minutes verify that the websites are responsive.
✑ Verify that the websites respond within a specified time threshold. Dependent requests such as images and JavaScript files must load properly.
✑ Generate alerts if a website is experiencing issues.
✑ If a website fails to load, the system must attempt to reload the site three more times.
You need to implement this process with the least amount of effort.

You develop and add several functions to an Azure Function app that uses the latest runtime host. The functions contain several REST API endpoints secured by using SSL. The Azure Function app runs in a Consumption plan.
You must send an alert when any of the function endpoints are unavailable or responding too slowly.
You need to monitor the availability and responsiveness of the functions.
What should you do?
Answer:
B
You can create an Azure Function with TrackAvailability() that will run periodically according to the configuration given in TimerTrigger function with your own business logic. The results of this test will be sent to your Application Insights resource, where you will be able to query for and alert on the availability results data.
This allows you to create customized tests similar to what you can do via Availability Monitoring in the portal. Customized tests will allow you to write more complex availability tests than is possible using the portal UI, monitor an app inside of your Azure VNET, change the endpoint address, or create an availability test even if this feature is not available in your region.
