You write the following query.
AzureDiagnostics
| where Category == "ControlPlaneRequests"
What should you include in the query?

A. | where OperationName startswith "AccountUpdateStart"
B. | where OperationName startswith "SqlContainersDelete"
C. | where OperationName startswith "MongoCollectionsThroughputUpdate"
D. | where OperationName startswith "SqlContainersThroughputUpdate"

Explanation:
The following are the operation names in diagnostic logs for different operations:
RegionAddStart, RegionAddComplete RegionRemoveStart, RegionRemoveComplete AccountDeleteStart, AccountDeleteComplete RegionFailoverStart, RegionFailoverComplete
AccountCreateStart, AccountCreateComplete
*AccountUpdateStart*, AccountUpdateComplete
VirtualNetworkDeleteStart, VirtualNetworkDeleteComplete
DiagnosticLogUpdateStart, DiagnosticLogUpdateComplete

Question#3

HOTSPOT
You have an Azure Cosmos DB Core (SQL) API account named account1.
You have the Azure virtual networks and subnets shown in the following table.



The vnet1 and vnet2 networks are connected by using a virtual network peer.
The Firewall and virtual network settings for account1 are configured as shown in the exhibit.



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


A. 

Explanation:
Box 1: Yes
VM1 is on vnet1.subnet1 which has the Endpoint Status enabled.
Box 2: No
Only virtual network and their subnets added to Azure Cosmos account have access. Their peered VNets cannot access the account until the subnets within peered virtual networks are added to the account.
Box 3: No
Only virtual network and their subnets added to Azure Cosmos account have access.

Question#4

HOTSPOT
You plan to deploy two Azure Cosmos DB Core (SQL) API accounts that will each contain a single database.
The accounts will be configured as shown in the following table.



How should you provision the containers within each account to minimize costs? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.


A. 

Explanation:
Box 1: Serverless capacity mode
Azure Cosmos DB serverless best fits scenarios where you expect intermittent and unpredictable traffic with long idle times. Because provisioning capacity in such situations isn't required and may be cost-prohibitive, Azure Cosmos DB serverless should be considered in the following use-cases:
Getting started with Azure Cosmos DB
Running applications with bursty, intermittent traffic that is hard to forecast, or low (<10%) average-to-peak traffic ratio Developing, testing, prototyping and running in production new applications where the traffic pattern is unknown Integrating with serverless compute services like Azure Functions
Box 2: Provisioned throughput capacity mode and autoscale throughput
The use cases of autoscale include:
Variable or unpredictable workloads: When your workloads have variable or unpredictable spikes in usage, autoscale helps by automatically scaling up and down based on usage. Examples include retail websites that have different traffic patterns depending on seasonality; IOT workloads that have spikes at various times during the day; line of business applications that see peak usage a few times a month or year, and more. With autoscale, you no longer need to manually provision for peak or average capacity.

Question#5

You have a container named container1 in an Azure Cosmos DB Core (SQL) API account.
You need to provide a user named User1 with the ability to insert items into container1 by using role-based access control (RBAC). The solution must use the principle of least privilege.
Which roles should you assign to User1?

A. CosmosDB Operator only
B. DocumentDB Account Contributor and Cosmos DB Built-in Data Contributor
C. DocumentDB Account Contributor only
D. Cosmos DB Built-in Data Contributor only

Explanation:
Cosmos DB Operator: Can provision Azure Cosmos accounts, databases, and containers.
Cannot access any data or use Data Explorer.
