You are developing a .NET Core MVC application for customers to research hotels. The
application will use Azure Search. The application will search the index by using various
criteria to locate documents related to hotels. The index will include search fields for rate, a
list of amenities, and distance to the nearest airport.
The application must support the following scenarios for specifying search criteria and
organizing results:
• Search the index by using regular expressions.
• Organize results by counts for name-value pairs.
• List hotels within a specified distance to an airport and that fall within a specific price
range.
You need to configure the SearchParameters class.
Which properties should you configure? To answer, select the appropriate options in the
answer area.
NOTE Each correct selection is worth one point.
Box 1: QueryType
The SearchParameters.QueryType Property gets or sets a value that specifies the syntax
of the search query. The default is 'simple'. Use 'full' if your query uses the Lucene query
syntax.
You can write queries against Azure Search based on the rich Lucene Query Parser syntax
for specialized query forms: wildcard, fuzzy search, proximity search, regular expressions
are a few examples.
Box 2: Facets
The facets property gets or sets the list of facet expressions to apply to the search query.
Each facet expression contains a field name, optionally followed by a comma-separated list
of name:value pairs.
Box 3: Filter
The Filter property gets or sets the OData $filter expression to apply to the search query.

You have the following code:
You are developing Azure WebJobs.
You need to recommend a WebJob type for each scenario.
Which WebJob type should you recommend? To answer, drag the appropriate WebJob
types to the correct scenarios. Each WebJob 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.
You are developing a web app that is protected by 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.

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.
In the Azure Application Gateway’s HTTP setting, enable the Use for App service
setting.
In the Azure Application Gateway’s HTTP setting, set the value of the Override backend
path option to contoso22.azurewebsites.net.
Explanation:
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 host name from the IP or FQDN of the back-end pool members.
HTTP settings also provide an option to dynamically pick the host name from a back-end
pool member's FQDN if configured with the option to derive host name from an individual
back-end pool member.
A (not C): SSL termination and end to end SSL with multi-tenant services.
In 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

You are implementing a software as a service (SaaS) ASP.NET Core web service that will
run as an Azure Web App. The web service will use an on-premises SQL Server database
for storage. The web service also includes a WebJob that processes data updates. Four
customers will use the web service.
•Each instance of the WebJob processes data for a single customer and must run as a
singleton instance.
•Each deployment must be tested by using deployment slots prior to serving production
data.
•Azure costs must be minimized.
•Azure resources must be located in an isolated network.
You need to configure the App Service plan for the Web App.
How should you configure the App Service plan? To answer, select the appropriate settings
in the answer area.

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?
A.
In the Azure portal, create a Batch account.
B.
In a .NET method, call the method: BatchClient.PoolOperations.CreatePool
C.
In Python, implement the class: JobAddParameter
D.
In Python, implement the class: TaskAddParameter
In a .NET method, call the method: BatchClient.PoolOperations.CreatePool
A Batch job is a logical grouping of one or more tasks. A job includes settings common to
the tasks, such as priority and the pool to run tasks on. The app uses the
BatchClient.JobOperations.CreateJob method to create a job on your pool.
A company develops a series of mobile games. All games use a single leaderboard
service.
You have the following requirements:
•Code should be scalable and allow for growth.
•Each record must consist of a playedId, gameId, score, and time played.
•When users reach a new high score, the system will save the new score using the
SaveScore function below.
•Each game is assigned and Id based on the series title.
You have the following code. (Line numbers are included for reference only.)
You store customer information in an Azure Cosmos database. The following data already
exists in the database:
Box 1: Yes
Code for CosmosDB, example:
// Parse the connection string and return a reference to the storage account.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("StorageConnectionString"));
// Create the table client.
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
// Retrieve a reference to the table.
CloudTable table = tableClient.GetTableReference("people");
// Create the TableOperation object that inserts the customer entity.
TableOperation insertOperation = TableOperation.Insert(customer1);
Box 2: No
A new record will always be added as TableOperation.Insert is used, instead of
TableOperation.InsertOrReplace.
Box 3: No
No partition key is used.
Box 4: Yes

Contoso, Ltd. provides an API to customers by using Azure API Management (APIM). The
API authorizes users with a JWT token.
You must implement response caching for the APIM gateway. The caching mechanism
must detect the user ID of the client that accesses data for a given location and cache the
response for that user ID.
You need to add the following policies to the policies file:
• a set-variable policy to store the detected user identity
• a cache-lookup-value policy
• a cache-store-value policy
• a find-and-replace policy to update the response body with the user profile information
To which policy section should you add the policies? To answer, drag the appropriate
sections to the correct policies. Each section 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
