Microsoft Developing Solutions for Microsoft Azure Sample Questions:
Hotspot Question
You are developing an Azure Durable Function based application that processes a list of input values. The application is monitored using a console application that retrieves JSON data from an Azure Function diagnostic endpoint.
During processing a single instance of invalid input does not cause the function to fail. Invalid input must be available to the monitoring application.
You need to implement the Azure Durable Function and the monitoring console application.
How should you complete the code segments? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation:
Box 1: await context.CallEntityAsync(input[errindex],"error")
Orchestration signals and calls an entity
Orchestrator functions can access entities by using APIs on the orchestration trigger binding.
Example:
[FunctionName("CounterOrchestration")]
public static async Task Run(
[OrchestrationTrigger] IDurableOrchestrationContext context)
{
var entityId = new EntityId(nameof(Counter), "myCounter");
// Two-way call to the entity which returns a value - awaits the response int currentValue = await context.CallEntityAsync<int>(entityId, "Get"); Box 2: Failed During processing a single instance of invalid input does not cause the function to fail.
Note: RuntimeStatus: One of the following values:
Failed: The instance failed with an error.
Completed: The instance has completed normally.
Terminated: The instance was stopped abruptly.
Pending: The instance has been scheduled but has not yet started running.
Running: The instance has started running.
ContinuedAsNew: The instance has restarted itself with a new history. This state is a transient state.
Box 3: Input
Invalid input must be available to the monitoring application.

Case Study 6 - Contoso, Ltd
Background
Overview
You are a developer for Contoso, Ltd. The company has a social networking website that is developed as a Single Page Application (SPA). The main web application for the social networking website loads user uploaded content from blob storage.
You are developing a solution to monitor uploaded data for inappropriate content. The following process occurs when users upload content by using the SPA:
* Messages are sent to ContentUploadService.
* Content is processed by ContentAnalysisService.
* After processing is complete, the content is posted to the social network or a rejection message
is posted in its place.
The ContentAnalysisService is deployed with Azure Container Instances from a private Azure Container Registry named contosoimages.
The solution will use eight CPU cores.
Azure Active Directory
Contoso, Ltd. uses Azure Active Directory (Azure AD) for both internal and guest accounts.
Requirements
ContentAnalysisService
The company's data science group built ContentAnalysisService which accepts user generated content as a string and returns a probable value for inappropriate content. Any values over a specific threshold must be reviewed by an employee of Contoso, Ltd.
You must create an Azure Function named CheckUserContent to perform the content checks.
Costs
You must minimize costs for all Azure services.
Manual review
To review content, the user must authenticate to the website portion of the ContentAnalysisService using their Azure AD credentials. The website is built using React and all pages and API endpoints require authentication. In order to review content a user must be part of a ContentReviewer role. All completed reviews must include the reviewer's email address for auditing purposes.
High availability
All services must run in multiple regions. The failure of any service in a region must not impact overall application availability.
Monitoring
An alert must be raised if the ContentUploadService uses more than 80 percent of available CPU cores.
Security
You have the following security requirements:
* Any web service accessible over the Internet must be protected from cross site scripting
attacks.
* All websites and services must use SSL from a valid root certificate authority.
* Azure Storage access keys must only be stored in memory and must be available only to the
service.
* All Internal services must only be accessible from internal Virtual Networks (VNets).
* All parts of the system must support inbound and outbound traffic restrictions.
* All service calls must be authenticated by using Azure AD.
User agreements
When a user submits content, they must agree to a user agreement. The agreement allows employees of Contoso, Ltd. to review content, store cookies on user devices, and track user's IP addresses.
Information regarding agreements is used by multiple divisions within Contoso, Ltd.
User responses must not be lost and must be available to all parties regardless of individual service uptime. The volume of agreements is expected to be in the millions per hour.
Validation testing
When a new version of the ContentAnalysisService is available the previous seven days of content must be processed with the new version to verify that the new version does not significantly deviate from the old version.
Issues
Users of the ContentUploadService report that they occasionally see HTTP 502 responses on specific pages.
Code
ContentUploadService
ApplicationManifest
You need to investigate the http server log output to resolve the issue with the ContentUploadService.

Hotspot Question
You are developing an application to collect the following telemetry data for delivery drivers: first name, last name, package count, item id, and current location coordinates. The app will store the data in Azure Cosmos DB.
You need to configure Azure Cosmos DB to query the data.
Which values should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation:
Box 1: Core (SQL)
Core(SQL) API stores data in document format. It offers the best end-to-end experience as we have full control over the interface, service, and the SDK client libraries. SQL API supports analytics and offers performance isolation between operational and analytical workloads.
Box 2: item id
item id is a unique identifier and is suitable for the partition key.
Reference:
https://docs.microsoft.com/en-us/azure/cosmos-db/choose-api
https://docs.microsoft.com/en-us/azure/cosmos-db/partitioning-overview
Drag and Drop Question
You have an application that provides weather forecasting data to external partners. You use Azure API Management to publish APIs.
You must change the behavior of the API to meet the following requirements:
- Support alternative input parameters
- Remove formatting text from responses
- Provide additional context to back-end services
Which types of policies should you implement? To answer, drag the policy types to the correct scenarios. Each policy type 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:
Box1: Inbound
<inbound>
<!-- statements to be applied to the request go here -->
</inbound>
<backend>
<!-- statements to be applied before the request is forwarded to
the backend service go here -->
</backend>
<outbound>
<!-- statements to be applied to the response go here -->
</outbound>
Box2: Outbound
Box3: Inbound
<!-- Copy this snippet into the inbound element to forward some context information, user id and the region the gateway is hosted in, to the backend service for logging or evaluation -->
<set-header name="x-request-context-data" exists-action="override">
<value>@(context.User.Id)</value>
<value>@(context.Deployment.Region)</value>
</set-header>
