Microsoft Azure Developer Associate AZ-204 Practice Question

Your application adds work items to an Azure Storage queue. A worker role dequeues one message at a time and starts processing. Some items require up to 10 minutes to finish. While a message is being processed, no other worker must be able to see it, even when processing lasts longer than the original visibility timeout that was set when the message was fetched. Which approach meets this requirement?

  • Set a 15-minute time-to-live (TTL) on each message when it is enqueued.

  • Periodically call UpdateMessageAsync on the in-process message, supplying a new visibility timeout that extends past the expected completion time.

  • Increase the queue's MaxDequeueCount setting to 20 in the Azure portal.

  • Read messages with PeekMessageAsync instead of ReceiveMessageAsync so the message remains hidden from other workers.
