HOTSPOT

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.

Correct Answer:

Explanation:

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).

DRAG DROP

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. NOTE: Each correct selection is worth one point

Correct Answer:

Explanation:

Box 1: Inbound.

A set-variable policy to store the detected user identity.

Example:

<policies>

<inbound>

<!– How you determine user identity is application dependent –>

<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 />

</outbound>

You are creating a hazard notification system that has a single signaling server which triggers audio and visual alarms to start and stop.

You implement Azure Service Bus to publish alarms. Each alarm controller uses Azure Service Bus to receive alarm signals as part of a transaction. Alarm events must be recorded for audit purposes. Each transaction record must include information about the alarm type that was activated.

You need to implement a reply trail auditing solution.

After you answer a question in this question, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You are developing a website that will run as an Azure Web App. Users will authenticate by using their Azure Active Directory (Azure AD) credentials.

You plan to assign users one of the following permission levels for the website: admin, normal, and reader. A user’s Azure AD group membership must be used to determine the permission level. You need to configure authorization.

Solution: Configure the Azure Web App for the website to allow only authenticated requests and require Azure AD log on.
