You are developing an Azure messaging solution.

You need to ensure that the solution meets the following requirements:

Provide transactional support.

Provide duplicate detection.

Store the messages for an unlimited period of time.

Which two technologies will meet the requirements? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Azure Service Bus Topic
Azure Service Bus Topic
Azure Service Bus Queue
Azure Service Bus Queue
Azure Storage Queue
Azure Storage Queue
Azure Event Hub
Azure Event Hub
Suggested answer: A, B

Explanation:

The Azure Service Bus Queue and Topic has duplicate detection.

Enabling duplicate detection helps keep track of the application-controlled MessageId of all messages sent into a queue or topic during a specified time window.

Incorrect Answers:

C: There is just no mechanism that can query a Storage queue and find out if a message with the same contents is already there or was there before.

D: Azure Event Hub does not have duplicate detection

DRAG DROP

You develop a gateway solution for a public facing news API.

The news API back end is implemented as a RESTful service and hosted in an Azure App Service instance.

You need to configure back-end authentication for the API Management service instance.

Which target and gateway credential type should you use? To answer, drag the appropriate values to the correct parameters. Each value 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.

HOTSPOT

You are creating an app that uses Event Grid to connect with other services. Your app's event data will be sent to a serverless function that checks compliance. This function is maintained by your company.

You write a new event subscription at the scope of your resource. The event must be invalidated after a specific period of time.

You need to configure Event Grid.

What should you do? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Correct answer: Microsoft AZ-204 image answer Question 203 86329 10022024015001000

Explanation:

Box 1: SAS tokens Custom topics use either Shared Access Signature (SAS) or key authentication. Microsoft recommends SAS, but key authentication provides simple programming, and is compatible with many existing webhook publishers.

In this case we need the expiration time provided by SAS tokens.

Box 2: ValidationCode handshake

Event Grid supports two ways of validating the subscription: ValidationCode handshake (programmatic) and ValidationURL handshake (manual).

If you control the source code for your endpoint, this method is recommended.

Incorrect Answers:

ValidationURL handshake (manual): In certain cases, you can't access the source code of the endpoint to implement the ValidationCode handshake. For example, if you use a third-party service (like Zapier or IFTTT), you can't programmatically respond with the validation code.

DRAG DROP

You are developing a REST web service. Customers will access the service by using an Azure API Management instance.

The web service does not correctly handle conflicts. Instead of returning an HTTP status code of 409, the service returns a status code of 500. The body of the status message contains only the word conflict.

You need to ensure that conflicts produce the correct response.

How should you complete the policy? To answer, drag the appropriate code segments to the correct locations. Each code 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.


Microsoft AZ-204 image Question 204 86330 10022024015001000
Correct answer: Microsoft AZ-204 image answer Question 204 86330 10022024015001000

Explanation:

Box 1: on-error

Policies in Azure API Management are divided into inbound, backend, outbound, and on-error.

If there is no on-error section, callers will receive 400 or 500 HTTP response messages if an error condition occurs.

Box 2: context

Box 3: context

Box 4: set-status The return-response policy aborts pipeline execution and returns either a default or custom response to the caller. Default response is 200 OK with no body.

Custom response can be specified via a context variable or policy statements.

Syntax:

<return-response response-variable-name="existing context variable">

<set-header/>

<set-body/>

<set-status/>

</return-response>

Box 5: on-error

DRAG DROP

You are a developer for a Software as a Service (SaaS) company. You develop solutions that provide the ability to send notifications by using Azure Notification Hubs.

Correct answer: Microsoft AZ-204 image answer Question 205 86331 10022024015001000

Explanation:

Box 1: windows

Example code:

var request = new HttpRequestMessage(method, $"{resourceUri}?api-version=2017-04");

request.Headers.Add("Authorization", createToken(resourceUri, KEY_NAME,

KEY_VALUE));

request.Headers.Add("X-WNS-Type", "wns/raw");

request.Headers.Add("ServiceBusNotification-Format", "windows");

return request;

Box 2: application/octet-stream

Example code capable of sending a raw notification:

string resourceUri = $"https://{NH_NAMESPACE}.servicebus.windows.net/{HUB_NAME}/messages/";

using (var request = CreateHttpRequest(HttpMethod.Post, resourceUri))

{

request.Content = new StringContent(content, Encoding.UTF8,

"application/octet-stream");

request.Content.Headers.ContentType.CharSet = string.Empty;

var httpClient = new HttpClient();

var response = await httpClient.SendAsync(request);

Console.WriteLine(response.StatusCode);

}

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 Event Hub. Configure the machine identifier as the partition key and enable capture.

Does the solution meet the goal?

DRAG DROP

You are developing an Azure solution to collect inventory data from thousands of stores located around the world. Each store location will send the inventory data hourly to an Azure Blob storage account for processing.

The solution must meet the following requirements:

Begin processing when data is saved to Azure Blob storage.

Filter data based on store location information.

Trigger an Azure Logic App to process the data for output to Azure Cosmos DB.

Enable high availability and geographic distribution.

Allow 24-hours for retries.

Implement an exponential back off data processing.

You need to configure the solution.

Correct answer: Microsoft AZ-204 image answer Question 207 86333 10022024015001000

Explanation:

Box 1: Azure Event Grid

Blob storage events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener. Event Grid provides reliable event delivery to your applications through rich retry policies and dead-lettering.

Box 2: Azure Logic App

Event Grid uses event subscriptions to route event messages to subscribers. This image illustrates the relationship between event publishers, event subscriptions, and event handlers.

Microsoft AZ-204 image Question 7 explanation 86333 10022024015001000000

Box 3: Azure Service Bus

The Event Grid service doesn't store events. Instead, events are stored in the Event Handlers, including ServiceBus, EventHubs, Storage Queue, WebHook endpoint, or many other supported Azure Services.
