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.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: Continuous

Continuous runs on all instances that the web app runs on. You can optionally restrict the WebJob to a single instance.

Box 2: Triggered

Triggered runs on a single instance that Azure selects for load balancing.

Box 3: Continuous

Continuous supports remote debugging.

Note:

The following table describes the differences between continuous and triggered WebJobs.

Correct Answer:

Explanation:

Azure database connection string retrieve REST API vault.azure.net/secrets/

Box 1: cpandlkeyvault

We specify the key vault, cpandlkeyvault.

Scenario: The database connection string is stored in Azure Key Vault with the following attributes:

Azure Key Vault name: cpandlkeyvault

Secret name: PostgreSQLConn

Id: 80df3e46ffcd4f1cb187f79905e9a1e8

Box 2: PostgreSQLConn

We specify the secret, PostgreSQLConn

Example, sample request:

https://myvault.vault.azure.net//secrets/mysecretname/4387e9f3d6e14c459867679a90fd0f79?api-version=7.1

Box 3: Querystring

You manage an Azure Key Vault named kv1 of Standard SKU.

You plan to programmatically store in kv1 an asymmetric key pair and use the key pair for encryption and decryption.

You must develop an application named app1 that will access the key pair in kv1.

You need to configure an object to retrieve a key pair from kv1.

Which object should you use?

You need to configure API Management for authentication.

Which policy values should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: Validate JWT

The validate-jwt policy enforces existence and validity of a JWT extracted from either a specified HTTP Header or a specified query parameter.

Scenario: User authentication (see step 5 below)

The following steps detail the user authentication process:

✑ The user selects Sign in in the website.

✑ The browser redirects the user to the Azure Active Directory (Azure AD) sign in page.

✑ The user signs in.

✑ Azure AD redirects the user’s session back to the web application. The URL includes an access token.

✑ The web application calls an API and includes the access token in the authentication header. The application ID is sent as the audience (‘aud’) claim in the access token.

✑ The back-end API validates the access token.

Box 2: Outbound

You are building a web application that performs image analysis on user photos and returns metadata containing objects identified. The image analysis is very costly in terms of time and compute resources. You are planning to use Azure Redo Cache so Cache uploads do not need to be reprocessed.

In case of an Azure data center outage metadata loss must be kept to a minimum.

You need to configure the Azure Redis cache instance.

You have an Azure Web app that uses Cosmos DB as a data store.

You create a CosmosDB container by running the following PowerShell script:

$resourceGroupName = "testResourceGroup"

$accountName = "testCosmosAccount"

$databaseName = "testDatabase"

$containerName = "testContainer"

$partitionKeyPath = "/EmployeeId"

$autoscaleMaxThroughput = 5000

New-AzCosmosDBSqlContainer

-ResourceGroupName $resourceGroupName

-AccountName $accountName

-DatabaseName $databaseName

-Name $containerName

-PartitionKeyKind Hash

-PartitionKeyPath $partitionKeyPath

-AutoscaleMaxThroughput $autoscaleMaxThroughput

You create the following queries that target the container:

SELECT * FROM c WHERE c.EmployeeId > ‘12345’

SELECT * FROM c WHERE c.UserID = ‘12345’

For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: No

You set the highest, or maximum RU/s Tmax you don’t want the system to exceed. The system automatically scales the throughput T such that 0.1* Tmax <= T <= Tmax.

In this example we have autoscaleMaxThroughput = 5000, so the minimum throughput for the container is 500 R/Us.

Box 2: No

First query: SELECT * FROM c WHERE c.EmployeeId > ‘12345’

Here’s a query that has a range filter on the partition key and won’t be scoped to a single physical partition. In order to be an in-partition query, the query must have an equality filter that includes the partition key:

SELECT * FROM c WHERE c.DeviceId > ‘XMS-0001’

Box 3: Yes

Example of In-partition query:

Consider the below query with an equality filter on DeviceId. If we run this query on a container partitioned on DeviceId, this query will filter to a single physical partition.

SELECT * FROM c WHERE c.DeviceId = ‘XMS-0001’
