ASP.NET Core API app by using C#. The API app will allow users to authenticate by using Twitter and Azure Active Directory (Azure AD).
Users must be authenticated before calling API methods. You must log the user’s name for
each method call.
You need to configure the API method calls.
Which values should you use? To answer, select the appropriate options in the answer
area.
NOTE: Each correct selection is worth one point.
+ Explanation:
Box 1: Authorize
Box 2: X-MS-CLIENT-PRINCIPAL-NAME
App Service passes user claims to your application by using special headers. External
requests aren't allowed to set these headers, so they are present only if set by App
Service. Some example headers include:
X-MS-CLIENT-PRINCIPAL-NAME
X-MS-CLIENT-PRINCIPAL-ID
Here's the set of headers you get from Easy Auth for a Twitter authenticated user:
{
"cookie": "AppServiceAuthSession=Lx43...xHDTA==",
"x-ms-client-principal-name": "evilSnobu",
"x-ms-client-principal-id": "35....",
"x-ms-client-principal-idp": "twitter",
"x-ms-token-twitter-access-token": "35...Dj",
"x-ms-token-twitter-access-token-secret": "OK3...Jx",
}

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 question sets might have more than one correct solution, while others
might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a
result, these questions will not appear in the review screen.
You are developing an Azure solution to collect point-of-sale (POS) device data from 2,000
stores located throughout the world. A single device can produce 2 megabytes (MB) of
data every 24 hours. Each store location has one to five devices that send data.
You must store the device data in Azure Blob storage. Device data must be correlated
based on a device identifier. Additional stores are expected to open in the future.
You need to implement a solution to receive the device data.
Solution: Provision an Azure Notification Hub. Register all devices with the hub.
Does the solution meet the goal?
A.
Yes
B.
No
No
Instead use an Azure Service Bus, which is used order processing and financial
transactions.

You are preparing to deploy a Python website to an Azure Web App using a container. The
solution will use multiple containers in the same container group. The Dockerfile that builds
the container is as follows:
Box 1: -SKU B1 -hyper-v
-hyper-v
Host web app on Windows container.
Box 2: -deployment-source-url images.azurecr.io/website:v1.0.0
-deployment-source-url -u
Git repository URL to link with manual integration.
The Web App must always run the same version of the website regardless of future builds.
Incorrect:
-deployment-container-image-name -i
Linux only. Container image name from Docker Hub, e.g. publisher/image-name:tag.
Box 3: az webapp config container set -url https://images.azurecr.io -u admin -p admin
az webapp config container set
Set a web app container's settings.
Paremeter: -docker-registry-server-url -r
The container registry server url.
The Azure Container Registry instance named images is a private registry.
Example:
az webapp config container set -docker-registry-server-url https://{azure-container-registryname}.
azurecr.io
You are developing a medical records document management website. The website is
used to store scanned copies of patient intake forms. If the stored intake forms are
downloaded from storage by a third party, the content of the forms must not be
compromised.
You need to store the intake forms according to the requirements.

Does the solution meet the goal?
A.
Yes
B.
No
No
You are developing a new page for a website that uses Azure Cosmos DB for data storage.
The feature uses documents that have the following format:
You must display data for the new page in a specific order. You create the following query
for the page:
You need to configure a Cosmos DB policy to the support the query.
How should you configure the policy? To answer, drag the appropriate JSON segments to
the correct locations. Each JSON segment 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.
Box 1: compositeIndexes
You can order by multiple properties. A query that orders by multiple properties requires a
composite index.
Box 2: descending
Example: Composite index defined for (name ASC, age ASC):
It is optional to specify the order. If not specified, the order is ascending.
{
"automatic":true,
"indexingMode":"Consistent",
"includedPaths":[
{
"path":"/*"
}
],
"excludedPaths":[],
"compositeIndexes":[
[
{
"path":"/name",
},
{
"path":"/age",
}
]
]
}
