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.

Richtige Antwort:

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 need to configure the Account Kind, Replication, and Storage tier options for the corporate website’s Azure Storage account.

Explanation:

Account Kind: StorageV2 (general-purpose v2)

Scenario: Azure Storage blob will be used (refer to the exhibit). Data storage costs must be minimized.

General-purpose v2 accounts: Basic storage account type for blobs, files, queues, and tables.

Recommended for most scenarios using Azure Storage.

Incorrect Answers:

BlockBlobStorage accounts: Storage accounts with premium performance characteristics for block blobs and append blobs. Recommended for scenarios with high transactions rates, or scenarios that use smaller objects or require consistently low storage latency.

General-purpose v1 accounts: Legacy account type for blobs, files, queues, and tables. Use general-purpose v2 accounts instead when possible.

Replication: Geo-redundant Storage

Scenario: Data must be replicated to a secondary region and three availability zones.

Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in the secondary region.

Incorrect Answers:

Geo-zone-redundant storage (GZRS), but it would be more costly.

Storage tier: Cool

Data storage costs must be minimized.

Note: Azure storage offers different access tiers, which allow you to store blob object data in the most cost-effective manner. The available access tiers include:

Hot – Optimized for storing data that is accessed frequently.

Cool – Optimized for storing data that is infrequently accessed and stored for at least 30 days.

Explanation:

Box 1: "oauth2Permissions": ["login"]

oauth2Permissions specifies the collection of OAuth 2.0 permission scopes that the web API (resource) app exposes to client apps. These permission scopes may be granted to client apps during consent.

Box 2: "oauth2AllowImplicitFlow":true

For applications (Angular, Ember.js, React.js, and so on), Microsoft identity platform supports the OAuth 2.0 Implicit Grant flow.

Explanation:

Box 1: orders o

Scenario: Order data is stored as nonrelational JSON and must be queried using SQL.

You develop a software as a service (SaaS) offering to manage photographs. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General-purpose V2.

When photos are uploaded, they must be processed to produce and save a mobile-friendly version of the image. The process to produce a mobile-friendly version of the image must start in less than one minute.

You need to design the process that starts the photo processing.

Solution: Move photo processing to an Azure Function triggered from the blob upload.

Explanation:

Box 1: Core (SQL)

Core (SQL) API stores data in document format. It offers the best end-to-end experience as we have full control over the interface, service, and the SDK client libraries. SQL API supports analytics and offers performance isolation between operational and analytical workloads.

Box 2: item id item id is a unique identifier and is suitable for the partition key.
