AZ-204: Developing Solutions for Microsoft Azure Practice Test - 1

 Question 1: Correct

You are developing a web service that should prevent anonymous usage and use OpenID connect for authentication.

You need to implement an API Management policy for the web service. Which policy should you use?

Explanation

Correct Answers:

Validate-jwt - The requirement from the question to validate requests using API management policy. You can use the Validate JWT policy to pre-authorize requests in API Management, by validating the access tokens of each incoming request. If a request does not have a valid token, API Management blocks it.

https://docs.microsoft.com/en-us/azure/api-management/api-management-howto-protect-backend-with-aad#configure-a-jwt-validation-policy-to-pre-authorize-requests

Wrong Answers:

Convert XML to JSON – This converts a request or response body from XML to JSON.

Validate-client-certificate – This policy enforces a certificate presented by a client matches with specified validation rules and claims.

Check-header – Check HTTP header policy enforces existence of a HTTP Header.

Question 2: Incorrect

You are developer for a company named Company1.

Company1 has an application that uses Azure Cosmos DB configured with Azure Cosmos DB SQL API.

The database contains millions of documents without distinct values for partitioning.

You need to implement a scaling strategy for the database to scale individual containers.

The database must meet the performance requirements of the application by spreading the workload evenly across all partitions over time.

You need to select a partition key.


Which two partition keys can you use?

Explanation

The goal is to distribute your data and workload evenly across the items associated with these partition key values. If such a property doesn’t exist in your data, you can construct a synthetic partition key.

You can form a partition key by concatenating multiple property values into a single artificial partition Key property. These keys are referred to as synthetic keys.

Another possible strategy to distribute the workload more evenly is to append a random number at the end of the partition key value. When you distribute items in this way, you can perform parallel write operations across partitions.

https://docs.microsoft.com/en-us/azure/cosmos-db/synthetic-partition-keys

Question 3: Incorrect

You developing an application named Application1 that uses Azure Blob storage named Storage1.

For audit purposes, Application1 must read the transaction logs of all changes that occur to the blobs and blob metadata in Storage1.

The changes must be in the order in which they occurred.

You need to process the logs asynchronously and should include only create, update, delete and copy operations.

What should you do to implement audit requirement?

Explanation

Change feed provides transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account.

The change feed provides ordered, guaranteed, durable, immutable, read-only log of these changes. Client applications can read these logs at any time, either in streaming or in batch mode.

https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-change-feed?tabs=azure-portal

Question 4: Incorrect

You are a developer for a company that publishes APIs using Azure API Management. You need to strip AspNet-Version from the response of the APIs.

What should you implement?

Explanation

You need to transform your API so it does not reveal info about the private backend. To delete the following headers in the HTTP response, you need to set a transformation policy.

X-Powered-By

X-AspNet-Version

https://docs.microsoft.com/en-us/azure/api-management/transform-api#transform-an-api-to-strip-response-headers

Question 5: Correct

You need to consume messages from a messaging component that is developed using Azure Service Bus publish-subscribe model.

You have initialized a subscription client object using correct details to process messages. However, the subscription application is still not consuming the messages.

Which of the below code segment should you use?

Explanation

RegisterMessageHandler handles messages one by one and completes them in the end.


https://docs.azure.cn/en-us/dotnet/api/microsoft.azure.servicebus.queueclient.registermessagehandler?view=azure-dotnet

Question 6: Correct

You have an Azure Storage account named StorageAccount1.

You plan to store data that is rarely accessed in StorageAccount1 for several years.

You must ensure that the data in Blob storage is always available for immediate access.

The solution must minimize storage costs.

Which storage tier should you use?

Explanation

The cool access tier has lower storage costs and higher access costs compared to hot storage. This tier is intended for data that will remain in the cool tier for at least 30 days. Example usage scenarios for the cool access tier include:

Short-term backup and disaster recovery datasets.

Older media content not viewed frequently anymore but is expected to be available immediately when accessed.

Large data sets that need to be stored cost effectively while more data is being gathered for future processing. (For example, long-term storage of scientific data, raw telemetry data from a manufacturing facility)

https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers?tabs=azure-portal

Question 7: Incorrect

You have a service principal named ServicePrincipal1.

You need to provide read access to ServicePrincipal1 to read the resources in a resource group named ResourceGroup1.

Select the actions that should you perform in the correct sequence?

Explanation

To access resources in your subscription, you must assign a role to the application. Permissions are inherited to lower levels of scope. For example, adding an application to the Reader role for a resource group means it can read the resource group and any resources it contains.

To assign a role at the resource group scope, search for and select “Resource Groups”, select the particular resource group, select Access Control (IAM), Select Add -> Add role assignment, Select the role you wish to add.

https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal#assign-a-role-to-the-application

Question 8: Correct

You are developing an application that executes short lived processes on a schedule.

You need to recommend a service that keeps costs and admin activities minimal.

What should you recommend?

Explanation

Azure Functions allows you to run small pieces of code (called "functions") without worrying about application infrastructure. A function is "triggered" by a specific type of event. Supported triggers include responding to changes in data, responding to messages, running on a schedule, or as the result of an HTTP request.

https://docs.microsoft.com/en-us/azure/azure-functions/functions-overview

Question 9: Incorrect

Which Azure RBAC roles allows you to upload images to an Azure Container Registry?

Explanation

The Azure Container Registry service supports a set of built-in Azure roles that provide different levels of permissions to an Azure container registry. Use Azure role-based access control (Azure RBAC) to assign specific permissions to users, service principals, or other identities that need to interact with a registry.

https://docs.microsoft.com/bs-latn-ba/azure/container-registry/container-registry-roles

Question 10: Correct

You have a mobile app that connects to the Azure App Service API to upload and extract metadata from the documents.

The process of extracting metadata is CPU-intensive operation. Usage of the mobile app has increased drastically.

You need to modify the App Service API to use a queue. The revised solution must scale and handle spikes in the number of requests.

You need to recommend a solution keeping costs minimal between request spikes.

What should you recommend?

Question 11: Correct

You define an API Policy object by using the below XML markup:


<set-variable name="bodySize" value="@(context.Request.Headers["Content-Length"][0])" />

<choose>

<when condition="@(int.Parse(context.Variables.GetValueOrDefault<string>("bodySize"))<400000)">

</when>

<otherwise>

<rewrite-uri template="/put"/>

<set-backend-service base-url="http://preparationlabs.com/api/8.1/"/>

</otherwise>

</choose>


Select Yes if the below statement is true. Otherwise, select No


1. The XML Segment is part of the <inbound> section of the API policy.

2. An error will be thrown if the body size is >265K

3. The policy will retain the higher version if the request is http://preparationlabs.com/api/8.2/

Explanation

1. The set-backend-service policy is used to redirect incoming requests. Therefore, this policy definition is part of inbound section

https://docs.microsoft.com/en-us/azure/api-management/api-management-advanced-policies#choose

2. The condition on body size 400K. So, you will not get an error.

3. There are conditions defined in the policy based on the body size. So, it will not retain the higher version always. The default/otherwise is version 8.1

Question 12: Incorrect

You have deployed several web applications into Azure App Service. You need to collect detailed resource logs for monitoring health and availability of Azure App Service.

Select the following options should you consider as destination?

Explanation

https://docs.microsoft.com/en-us/azure/azure-monitor/essentials/diagnostic-settings?tabs=CMD#destinations

Question 13: Incorrect

A software as a service (SaaS) company is developing a web service for several customers.

The web service connects to a SQL database in an on-premise environment. You plan to deploy the web service to an Azure Web App.

The web service also includes a WebJob that processes data and each instance of WebJob must process data for a single customer.

You need to configure Azure resources in an isolated network.

Which pricing tier should you consider for the App Service plan keeping costs minimal?

Explanation

The Isolated service plan is designed to run mission-critical workloads that are required to run in a virtual network. The Isolated plan allows customers to run their apps in a private, dedicated environment in an Azure data centre.

https://azure.microsoft.com/en-au/pricing/details/app-service/windows/

Question 14: Correct

You have an application named Application1 in an Azure App Service named AppService1.

Your application users are currently accessing Application1 using http://employeerewards.com.

You need to enforce Application1 users to use https://employeerewards.com.

What changes should you implement?

Explanation

By default, you can access your app using HTTP. You can redirect all HTTP requests to the HTTPS port.

In your app page, in the left navigation, select SSL settings. Then, in HTTPS Only, select On.

https://docs.microsoft.com/en-us/azure/app-service/configure-ssl-bindings#enforce-https

Question 15: Incorrect

You have uploaded a certificate to an Azure Web App named Application1.

You need to access the certificate from the app code of Application1.

What should you configure?

Explanation

In your application code, you can access the public or private certificates you add to App Service. Your app code may act as a client and access an external service that requires certificate authentication, or it may need to perform cryptographic tasks.

The WEBSITE_LOAD_CERTIFICATES app setting makes the specified certificates accessible to your Windows hosted app in the Windows certificate store,

https://docs.microsoft.com/en-us/azure/app-service/configure-ssl-certificate-in-code

Question 16: Incorrect

You have an Azure Active Directory (Azure AD) tenant.

You need to register an application with your Azure AD tenant.

Which three actions should you perform in sequence?

Explanation

Registering your application establishes a trust relationship between your app and the Microsoft identity platform.


Follow these steps to create the app registration:

Sign in to the Azure portal.

If you have access to multiple tenants, use the Directories + subscriptions filter in the top menu to switch to the tenant in which you want to register the application.

Search for and select Azure Active Directory.

Under Manage, select App registrations > New registration.

Enter a display Name for your application. Users of your application might see the display name when they use the app, for example during sign-in. You can change the display name at any time and multiple app registrations can share the same name. The app registration's automatically generated Application (client) ID, not its display name, uniquely identifies your app within the identity platform.

Specify who can use the application, sometimes called its sign-in audience.

Don't enter anything for Redirect URI (optional). You'll configure a redirect URI in the next section.

Select Register to complete the initial app registration.

https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app

Question 17: Incorrect

You need to implement an Azure monitoring service that can analyze how many users return to the application and how often they select a particular dropdown value.

Which service should you use?

Explanation

Custom events and metrics in App insights allow you write yourself in the client or server code, to track business events such as items sold or games won.

https://docs.microsoft.com/en-us/azure/azure-monitor/app/app-insights-overview

Question 22: Incorrect

You have a web application that is deployed to an Azure App Service.

You need to implement an Azure monitoring service that can visualize the relationships between application components.

Which service should you use?

Explanation

Application Map helps you spot performance bottlenecks or failure hotspots across all components of your distributed application. You can see the full application topology across multiple levels of related application components. Components could be different Application Insights resources, or different roles in a single resource. The app map finds components by following HTTP dependency calls made between servers with the Application Insights SDK installed.

https://docs.microsoft.com/en-us/azure/azure-monitor/app/app-map?tabs=net

Question 23: Incorrect

You are developing a solution that uses publish-subscribe model and eliminates the need for constant polling.

Select the two possible Azure messaging services to achieve the requirement.

Explanation

Event Grid - Event Grid is an eventing backplane that enables event-driven, reactive programming. It uses a publish-subscribe model. Publishers emit events, but have no expectation about which events are handled. Subscribers decide which events they want to handle.

Service Bus Topics and subscriptions enable relationships between publishers and subscribers.

https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-messaging-overview

https://docs.microsoft.com/en-us/azure/event-grid/compare-messaging-services#event-vs-message-services

The application needs to store runtime diagnostic data that must be persisted across application restarts. You have the following code:


You need to configure the application settings so that diagnostic data is stored as required.

How should you configure the web app's settings?

Explanation

If WEBSITES_ENABLE_APP_SERVICE_STORAGE setting is unspecified or set to true, the /home/ directory will be shared across scale instances, and files written will persist across restarts. Explicitly setting WEBSITES_ENABLE_APP_SERVICE_STORAGE to false will disable the mount.

https://docs.microsoft.com/en-us/azure/app-service/faq-app-service-linux

Question 30: Correct

You are developing an application for your client that uses Azure Storage Queues.

One of the method in the application contains the following code:


Select Yes if the below statement is true. Select No if the below statement is false.


1. The code configures the lock duration for the queue

2. After the code runs, the last message read remains in the queue

3. After the code runs, the storage queue remains in the storage account

Explanation

1. Code is not implementing any locks on the queue. So it is NO

2. Messages are not deleted automatically from Azure Storage account queues and program is not deleting. So it is Yes

https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-azure-and-service-bus-queues-compared-contrasted#comparing-storage-queues-and-service-bus-queues

3. The queue remains in the storage account because the code is not deleting it.

Question 31: Correct

You are developing a web application that will be hosted in an Azure Web App.

The users for web application will be authenticated by using their Azure Active Directory (Azure AD).

Users will be assigned with one of the following permission levels: admin, normal, and reader.

A user's Azure AD group membership must be used to determine the permission level.


To achieve the above requirement, you have created a new Azure AD application and configured the value of the groupMembershipClaims option to All in the application's manifest. In the web application, you use the value of the groups claim from the JWT for the user to determine permissions.

Did you achieve the requirement?

Explanation

To configure group’s optional claims through the application manifest, use groupMembershipClaims.

The valid values for groupMembershipClaims are:

"All" (this option includes SecurityGroup, DirectoryRole, and DistributionList)

"SecurityGroup"

"DirectoryRole"

"ApplicationGroup" (this option includes only groups that are assigned to the application)


https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-optional-claims

Question 32: Correct

You are developing a web application that will be hosted in an Azure Web App.

The users for web application will be authenticated by using their Azure Active Directory (Azure AD).

Users will be assigned with one of the following permission levels: admin, normal, and reader.

A user's Azure AD group membership must be used to determine the permission level.


To achieve the above requirement, you have configured the Azure Web App for the website to allow only authenticated requests and require Azure AD log on

Did you achieve the requirement?

Explanation

You also need to configure app manifest file to get the user's groups.

Question 33: Correct

You are developing a web application that will be hosted in an Azure Web App.

The users for web application will be authenticated by using their Azure Active Directory (Azure AD).

Users will be assigned with one of the following permission levels: admin, normal, and reader.

A user's Azure AD group membership must be used to determine the permission level.


To achieve the above requirement, you have assigned the appropriate Azure AD groups to each role. You have created a new Azure AD application and defined application roles that match the required permission levels for the application in the applications manifest. In the web application, you use the value of the groups claim from the JWT for the user to determine permissions.

Did you achieve the requirement?

Explanation

You define app roles by using the Azure portal. App roles are usually defined on an application registration representing a service, app or API. When a user signs in to the application, Azure AD emits a roles claim for each role that the user or service principal has been granted individually to the user and from their group membership.

https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-add-app-roles-in-azure-ad-apps#app-manifest-editor

Question 34: Incorrect

You are developing a web application that will be hosted in an Azure Web App.

The users for web application will be authenticated by using their Azure Active Directory (Azure AD).

Users will be assigned with one of the following permission levels: admin, normal, and reader.

A user's Azure AD group membership must be used to determine the permission level.


To achieve the requirement, you configure and use Integrated Windows Authentication in the website. In the website, query Microsoft Graph API to load the group to which the user is a member.

Did you achieve the requirement?

Explanation

It is not possible to configure windows authentication in Azure web app. You can use Azure AD.

Question 35: Correct

You are implementing authentication for an Azure API.

All calls to the API must be secure and callers should not send credentials to the API.

All callers to the API are hosted in Azure services.

Which authentication mechanism should you implement?

Explanation

The managed identity policy essentially uses the managed identity to obtain an access token from Azure Active Directory for accessing the specified resource. After successfully obtaining the token, the policy will set the value of the token in the Authorization header using the Bearer scheme.

For managed identity, we no need to send any credentials.

https://docs.microsoft.com/bs-cyrl-ba/azure/api-management/api-management-authentication-policies#ManagedIdentity

Question 36: Incorrect

You are developing an ASP.NET web app that will be deployed to an Azure App Service.

You use Application Insights telemetry to monitor the app. You need to configure a test for the web app.

You must test the app to ensure that the app is available and responsive from various points around the world and at regular intervals.

If the app is not responding, you must send an alert to support staff.


Which two test types should you use?

Explanation

After you've deployed your web app/website, you can set up recurring tests to monitor availability and responsiveness. Azure Application Insights sends web requests to your application at regular intervals from points around the world. It can alert you if your application isn't responding, or if it responds too slowly.


Types of availability tests:

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.


https://docs.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability

Question 37: Correct

You are developing an application that uses a micro service architecture.

You need to design a communication service for communicating transactional messages between various parts of the solution.

Messages must be communicated in first-in-first-out (FIFO) order.

What service should you consider?

Explanation

Azure Service Bus queue provides a guaranteed first-in-first-out (FIFO) ordered delivery.

https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-azure-and-service-bus-queues-compared-contrasted

Question 38: Correct

You have an application that use Azure API Management to publish APIs for external partners.

You must change the behavior of the API to support alternative input parameters

Which type of policy should you implement to rewrite the request URL to match to the format expected by the web service?

Explanation

The rewrite-uri policy converts a request URL from its public form to the form expected by the web service. Rewrite URI is part of Inbound section.

https://docs.microsoft.com/en-us/azure/api-management/api-management-transformation-policies#RewriteURL

Question 39: Incorrect

You have an application that use Azure API Management to publish APIs for external partners.

You must change the behavior of the API to remove formatting text from responses

Which type of policy should you implement?

Explanation

As we need to remove the text from the response, it should be in outbound section.
https://docs.microsoft.com/en-us/azure/api-management/policies/filter-response-content

Question 40: Incorrect

You have an application that use Azure API Management to publish APIs for external partners.

You must change the behavior of the API to provide additional context to back-end services


Which type of policy should you implement to forward the user ID that is associated with the subscription key for the original request to the back-end service?

Explanation

Below is the sample snippet of the policy to send user context to backend service.


<policies>

<inbound>

<base />

<!-- Forward the name of the product associated with the subscription key in the request to the backend service. -->

<set-query-parameter name="x-product-name" exists-action="override">

<value>@(context.Product.Name)</value>

</set-query-parameter>


<!-- Forward the user id associated with the subscription key in the request as well as the region where the proxy processing the request is hosted. -->

<set-header name="x-request-context-data" exists-action="override">

<value>@(context.User.Id)</value>

<value>@(context.Deployment.Region)</value>

</set-header>

</inbound>


The configuration is part of inbound section.

Question
You need to monitor ContentUploadService according to the requirements.

Which command should you use?

Explanation

Scenario: An alert must be raised if the ContentUploadService uses more than 80 percent of available CPU-cores


Azure Monitor provides the following metrics for Azure Container Instances. These metrics are available for a container group and individual containers. By default, the metrics are aggregated as averages.

CPU Usage - measured in millicores. One millicore is 1/1000th of a CPU core, so 500 millicores represents usage of 0.5 CPU core.

Memory Usage - in bytes.

Network Bytes Received Per Second and Network Bytes Transmitted Per Second.

Question 51: Incorrect

You have a new Azure subscription.

You are developing an internal website for employees to view sensitive data.

The website uses Azure Active Directory (Azure AD) for authentication.

You need to implement multifactor authentication for the website.


Which two actions should you perform?

Explanation

Correct Answer(s):

Multi-factor authentication (MFA) is a process in which a user is prompted for additional forms of identification during a sign-in event. For example, the prompt could be to enter a code on their cellphone or to provide a fingerprint scan. When you require a second form of identification, security is increased because this additional factor isn't easy for an attacker to obtain or duplicate.


Azure AD Multi-Factor Authentication and Conditional Access policies give you the flexibility to require MFA from users for specific sign-in events.

Prerequisite to configure conditional access policy is at least an Azure AD Premium P1 license.

https://docs.microsoft.com/en-us/azure/active-directory/authentication/tutorial-enable-azure-mfa


Wrong Answers:

Configure the website to use Azure AD B2C - Azure Active Directory B2C provides business-to-customer identity as a service. Your customers use their preferred social, enterprise, or local account identities to get single sign-on access to your applications and APIs.

In Azure AD, enable application proxy - Application Proxy is a feature of Azure AD that enables users to access on-premises web applications from a remote client.

In Azure AD conditional access, enable the baseline policy -Baseline Policy in Conditional Access are part of Baseline Protection in Azure Active Directory (Azure AD) and the goal of these policies is to ensure that you have at least the baseline level of security enabled in Azure AD.
