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.
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’

You are creating a script that will run a large workload on an Azure Batch pool. Resources will be reused and do not need to be cleaned up after use.
You have the following parameters:
You need to write an Azure CLI script that will create the jobs, tasks, and the pool.
In which order should you arrange the commands to develop the solution? To answer, move the appropriate commands from the list of command segments to the answer area and arrange them in the correct order.
Explanation:
Step 1: az batch pool create
# Create a new Linux pool with a virtual machine configuration. az batch pool create
–id mypool
–vm-size Standard_A1 –target-dedicated 2
–image canonical:ubuntuserver:16.04-LTS
–node-agent-sku-id "batch.node.ubuntu 16.04"
Step 2: az batch job create
# Create a new job to encapsulate the tasks that are added. az batch job create
–id myjob
–pool-id mypool
Step 3: az batch task create
# Add tasks to the job. Here the task is a basic shell command. az batch task create
–job-id myjob –task-id task1

You develop an HTTP triggered Azure Function app to process Azure Storage blob data. The app is triggered using an output binding on the blob.
The app continues to time out after four minutes. The app must process the blob data.
You need to ensure the app does not time out and processes the blob data.
Solution: Update the functionTimeout property of the host.json project file to 10 minutes.
Does the solution meet the goal?
- A . Yes
- B . No
B
Explanation:
Instead pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a queue trigger function and return an immediate HTTP success response.
Note: Large, long-running functions can cause unexpected timeout issues.
General best practices include:
Whenever possible, refactor large functions into smaller function sets that work together and return responses fast. For example, a webhook or HTTP trigger function might require an acknowledgment response within a certain time limit; it’s common for webhooks to require an immediate response.
You can pass the HTTP trigger payload into a queue to be processed by a queue trigger function. This approach lets you defer the actual work and return an immediate response.
