Answer:

Explanation:

Box 1: CompanyID

After you create a container with a unique key policy, the creation of a new or an update of an existing item resulting in a duplicate within a logical partition is prevented, as specified by the unique key constraint. The partition key combined with the unique key guarantees the uniqueness of an item within the scope of the container.

For example, consider an Azure Cosmos container with Email address as the unique key constraint and CompanyID as the partition key. When you configure the user’s email address with a unique key, each item has a unique email address within a given CompanyID. Two items can’t be created with duplicate email addresses and with the same partition key value.

Box 2: emailAddress
