An alpine-hut booking API has a Cosmos DB account in the portal, but the application still cannot read or write data. What must the developer instantiate first in code?
Select an answer to reveal the explanation.
Short Explanation
The portal’s Data Explorer is a flashlight for humans, not the app’s front door. Spin up a CosmosClient with endpoint and credential—that’s how the booking API actually talks to Cosmos.
Full Explanation
Application access begins with the Cosmos DB SDK client (CosmosClient or equivalent), using the account endpoint and an auth key or credential. Portal Data Explorer is an interactive tool, not the runtime path. AKS CSI drivers and Front Door are unrelated to constructing the Cosmos SDK entry point for this skill.
