Microsoft AZ-204 Online Exam Practice Questions
QUESTION 1
You are developing a web app that is protected by the Azure Web Application Firewall (WAF). All traffic to the web app is
routed through an Azure Application Gateway instance that is used by multiple web apps. The web app address is
contoso.azurewebsites.net.
All traffic must be secured with SSL. The Azure Application Gateway instance is used by multiple web apps.
You need to configure the Azure Application Gateway for the app.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. In the Azure Application Gateway\\’s HTTP setting, enable the Use for App service setting.
B. Convert the web app to run in an Azure App Service Environment (ASE).
C. Add an authentication certificate for contoso.azurewebsites.net to the Azure Application gateway.
D. In the Azure Application Gateway, \\’s HTTP setting set the value of the Override backend path option to
contoso22.azurewebsites.net.
Correct Answer: AD
D: The ability to specify a host override is defined in the HTTP settings and can be applied to any back-end pool during
rule creation. The ability to derive the hostname from the IP or FQDN of the back-end pool members. HTTP settings
also
provide an option to dynamically pick the hostname from a back-end pool member\\’s FQDN if configured with the
option to derive hostname from an individual back-end pool member.
A (not C): SSL termination and end to end SSL with multi-tenant services.
In the case of end to end SSL, trusted Azure services such as Azure App Service web apps do not require whitelisting the
backends in the application gateway. Therefore, there is no need to add any authentication certificates.

QUESTION 2
HOTSPOT
You are validating the configuration of an Azure Search indexer.
The service has been configured with an indexer that uses the Import Data option. The index is configured using options
as shown in the Index Configuration exhibit. (Click the Index Configuration tab.)
You use an Azure table as the data source for the import operation. The table contains three records with item inventory
data that match the fields in the Storage data exhibit. These records were imported when the index was created.
(Click the Storage Data tab.) When users search with no filter, all three records are displayed.
When users search for items by description, Search explorer returns no records. The Search Explorer exhibit shows the
query and results for a test. In the test, a user is trying to search for all items in the table that have a description that
contains the word bag. (Click the Search Explorer tab.)
You need to resolve the issue.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Box 1: Yes
The item description field is not searchable.
Box 2: No
The item description field is not searchable, but we would need to recreate the index.
Box 3: Yes
An indexer in Azure Search is a crawler that extracts searchable data and metadata from an external Azure data source
and populates an index based on field-to-field mappings between the index and your data source. This approach is
sometimes referred to as a \\’pull model\\’ because the service pulls data in without you having to write any code that
adds data to an index.
Box 4: No

by providing a name, pricing tier, subscription, resource group, and location.
You need to complete the configuration.
Which Azure CLI or PowerShell command should you run?
A. B. C. D.
Correct Answer: B
# Create a Service Bus messaging namespace with a unique name. Example:
namespaceName=myNameSpace$RANDOM az servicebus namespace create –resource-group $resourceGroupName
–name $namespaceName –location eastus

QUESTION 4
HOTSPOT
You have a web service that is used to pay for food deliveries. The web service uses Azure Cosmos DB as the data
store.
You plan to add a new feature that allows users to set a tip amount. The new feature requires that a property named tip
on the document in Cosmos DB must be present and contain a numeric value.
There are many existing websites and mobile apps that use the web service that will not be updated to set the tip
property for some time.
How should you complete the trigger?
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Box 1: getContext().getRequest();
Box 2: if(isNaN(i)[“tip”] ..
In JavaScript, there are two ways to check if a variable is a number :
isNaN() – Stands for “is Not a Number”, if the variable is not a number, it returns true, else return false.
typeof – If a variable is a number, it will return a string named “number”.
Box 3:r.setBody(i);

You are developing a software solution for an autonomous transportation system. The solution uses large data sets and
Azure Batch processing to simulate navigation sets for entire fleets of vehicles.
You need to create compute nodes for the solution on Azure Batch.
What should you do?
Put the actions in the correct order.
Select and Place:
Correct Answer:
With the Azure Portal:
Step 1: In the Azure portal, create a Batch account.
First, we create a batch account.
Step 2: In the Azure portal, create a pool of compute nodes
Now that you have a Batch account, create a sample pool of Windows compute nodes for test purposes.
Step 3: In the Azure portal, add a Job.
Now that you have a pool, create a job to run on it. A Batch job is a logical group for one or more tasks. A job includes
settings common to the tasks, such as priority and the pool to run tasks on. Initially, the job has no tasks.
Step 4: In the Azure portal, create tasks
Now create sample tasks to run in the job. Typically you create multiple tasks that Batch queues and distributes to run
on the compute nodes.

Correct Answer: DF
D: CorrelationId: Enables an application to specify a context for the message for the purposes of correlation; for
example, reflecting the MessageId of a message that is being replied to.
F: ReplyToSessionId: This value augments the ReplyTo information and specifies which SessionId should be set for the
reply when sent to the reply entity.
Incorrect Answers:
A, B: DeliveryCount
A number of deliveries that have been attempted for this message. The count is incremented when a message lock
expires, or the message is explicitly abandoned by the receiver. This property is read-only.
C, E: SequenceNumber
The sequence number is a unique 64-bit integer assigned to a message as it is accepted and stored by the broker and
functions as its true identifier. For partitioned entities, the topmost 16 bits reflect the partition identifier. Sequence
numbers
monotonically increase and are gapless. They roll over to 0 when the 48-64 bit range is exhausted. This property is read-only.
