What should you do first?

You have a database in an Azure Cosmos DB Core (SQL) API account. The database is backed up every two hours.
You need to implement a solution that supports point-in-time restore.
What should you do first?
A. Enable Continuous Backup for the account.
B. Configure the Backup & Restore settings for the account.
C. Create a new account that has a periodic backup policy.
D. Configure the Point In Time Restore settings for the account.

ANSWER: A
Explanation:
When creating a new Azure Cosmos DB account, in the Backup policy tab, choose continuous mode to enable the point in time restore functionality for the new account. With the point-in-time restore, data is restored to a new account, currently you can’t restore to an existing account.
