You have an Azure Cosmos DB for NoSQL account1 that is configured for automatic failover. The account1 account has a single read-write region in West US and a and a read region in East US.

You run the following PowerShell command.

What is the effect of running the command?

AA manual failover will occur.

BThe account will be unavailable to writes during the change.

CThe provisioned throughput for account1 will increase.

DThe account will be configured for multi-region writes.

Show Suggested Answer

Suggested Answer: B

You can use the Set-AzCosmosDBAccountRegion cmdlet to update the regions that an Azure Cosmos DB account uses. You can use this cmdlet to add a region or change the region failover order.The cmdlet requires a resource group name, an Azure Cosmos DB account name, and a list of regions in desired failover order1.

For your scenario, based on the PowerShell command, you are using the Set-AzCosmosDBAccountRegion cmdlet to update the regions for an Azure Cosmos DB account named account1 that is configured for automatic failover. The command specifies two regions: West US and East US. The effect of running the command is thatthe account will be configured for multi-region writes.

Multi-region writes is a feature of Azure Cosmos DB that allows you to write data to any region in your account and have it automatically replicated to all other regions. This feature provides high availability and low latency for write operations across multiple regions.To enable multi-region writes, you need to specify at least two regions in your account and set them as write regions2. In your command, you are setting both West US and East US as write regions by using the -IsZoneRedundant parameter with a value of $true for both regions.

A manual failover, huh? Sounds like a cosmic dance of data centers. I'll go with B just to be safe - don't want any write-ups for my cosmos mishaps!

D seems like the correct answer to me. The command is adding a read region, which means the account will be configured for multi-region writes.

I think the answer is B. The account will be unavailable to writes during the change. The command is used to add a read region, which means the account will be temporarily unavailable for writes.
