Which storage resource does the Functions runtime require for triggers, leases, and Durable state?
- A A Cosmos DB account
- B An Azure Storage account referenced by AzureWebJobsStorage (correct answer)
- C A Redis cache
- D A SQL database
Shortcut: The runtime uses the storage account for timer leases, blob trigger receipts, and Durable task hubs. Losing or misconfiguring it breaks triggering entirely.
