Explanation:
Scenario: You have a shared library named PolicyLib that contains functionality common to all ASP.NET Core web services and applications.
The PolicyLib library must:
✑ Exclude non-user actions from Application Insights telemetry.
✑ Provide methods that allow a web service to scale itself.
✑ Ensure that scaling actions do not disrupt application usage.
Box 1: ITelemetryInitializer
Use telemetry initializers to define global properties that are sent with all telemetry; and to override selected behavior of the standard telemetry modules.
Box 2: Initialize
Box 3: Telemetry.Context
Box 4: ((EventTelemetry)telemetry).Properties["EventID"]

You are developing a .NET Core MVC application for customers to research hotels. The application will use Azure Search. The application will search the index by using various criteria to locate documents related to hotels. The index will include search fields for rate, a list of amenities, and distance to the nearest airport.
The application must support the following scenarios for specifying search criteria and organizing results:
• Search the index by using regular expressions.
• Organize results by counts for name-value pairs.
• List hotels within a specified distance to an airport and that fall within a specific price
range.
You need to configure the SearchParameters class.
Which properties should you configure? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer

Answer:


Explanation:
Box 1: QueryType
The SearchParameters.QueryType Property gets or sets a value that specifies the syntax
of the search query. The default is 'simple'. Use 'full' if your query uses the Lucene query syntax.
You can write queries against Azure Search based on the rich Lucene Query Parser syntax for specialized query forms: wildcard, fuzzy search, proximity search, regular expressions are a few examples.
Box 2: Facets
The facets property gets or sets the list of facet expressions to apply to the search query. Each facet expression contains a field name, optionally followed by a comma-separated list of name:value pairs.
Box 3: Filter
The Filter property gets or sets the OData $filter expression to apply to the search query.

You need to configure API Management for authentication.
Which policy values should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer

Answer:


Explanation:
Box 1: Validate JWT
The validate-jwt policy enforces existence and validity of a JWT extracted from either a specified HTTP Header or a specified query parameter.
Scenario: User authentication (see step 5 below)
The following steps detail the user authentication process:
✑ The user selects Sign in in the website.
✑ The browser redirects the user to the Azure Active Directory (Azure AD) sign in page.
✑ The user signs in.
✑ Azure AD redirects the user’s session back to the web application. The URL includes an access token.
✑ The web application calls an API and includes the access token in the authentication header. The application ID is sent as the audience (‘aud’) claim in the access token.
✑ The back-end API validates the access token.

You need to configure security and compliance for the corporate website files.
Which Azure Blob storage settings should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer

Answer:


Explanation:
Box 1: role-based access control (RBAC)
Azure Storage supports authentication and authorization with Azure AD for the Blob and Queue services via Azure role-based access control (Azure RBAC).
Scenario: File access must restrict access by IP, protocol, and Azure AD rights.
Box 2: change feed
The purpose of the change feed is to provide transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account.
The file updates must be read-only, stored in the order in which they occurred, include only create, update, delete, and copy operations, and be retained for compliance reasons.

Explanation:
Scenario: You test the Logic app in a development environment.
The following error message displays:
'400 Bad Request'
Troubleshooting of the error shows an HttpTrigger action to call the RequestUserApproval function.
NOTE: If the inbound call's request body doesn't match your schema, the trigger returns an HTTP 400 Bad Request error.
Box 1: function
If you have an Azure function where you want to use the system-assigned identity, first enable authentication for Azure functions.
Box 2: system-assigned
Your logic app or individual connections can use either the system-assigned identity or a single user-assigned identity, which you can share across a group of logic apps, but not both.

Contoso, Ltd. provides an API to customers by using Azure API Management (APIM). The API authorizes users with a JWT token.
You must implement response caching for the APIM gateway. The caching mechanism must detect the user ID of the client that accesses data for a given location and cache the response for that user ID.
You need to add the following policies to the policies file:
• a set-variable policy to store the detected user identity
• a cache-lookup-value policy
• a cache-store-value policy
• a find-and-replace policy to update the response body with the user profile information
To which policy section should you add the policies? To answer, drag the appropriate sections to the correct policies. Each section 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

<set-variable
name="enduserid"
value="@(context.Request.Headers.GetValueOrDefault("Authorization","").Split('
')[1].AsJwt()?.Subject)" />
Box 2: Inbound
A cache-lookup-value policy
Example:
<inbound>
<base />
<cache-lookup vary-by-developer="true | false"
vary-by-developer-groups="true | false"
downstream-caching-type="none | private | public"
must-revalidate="true | false">
<vary-by-query-parameter>parameter name</vary-by-query-parameter>
<!-- optional, can repeated several times -->
</cache-lookup>
</inbound>
Box 3: Outbound
A cache-store-value policy.
Example:
<outbound>
<base />
<cache-store duration="3600" />
</outbound>
Box 4: Outbound
A find-and-replace policy to update the response body with the user profile information.
Example:
<outbound>
<!-- Update response body with user profile-->
<find-and-replace
from='"$userprofile$"'
to="@((string)context.Variables["userprofile"])" />
<base />
