A lantern-festival ticketing app’s Cosmos container create fails when the team passes only a container name. What required property must the SDK supply at create time?
Select an answer to reveal the explanation.
Short Explanation
Naming the container isn’t enough—Cosmos needs to know the partition-key path when you create it. Give the SDK that path or the create call won’t fly.
Full Explanation
Creating a Cosmos DB container through the SDK requires a partition-key path among the container properties. Without it, create operations fail. Redis, Kubernetes namespaces, and Azure SQL pools are not Cosmos container create requirements for AZ-204. Partition-key design depth beyond supplying the path belongs to specialty data exams.
