   A retail company uses an Azure Service Bus queue to process order messages. A downstream inventory service occasionally throws a transient exception that is not resolved by the default retry count. The team needs to isolate these problematic messages so they do not block the queue and can be analyzed later. What should you configure?

   • AEnable dead-lettering on the queue and set the MaxDeliveryCount to a value that allows a few retries before moving the message to the dead-letter queue.
   • BCreate a second queue and manually copy all messages that fail from the first queue to the second queue using a scheduled job.
   • CSet the queue's LockDuration to a very short time so that messages expire quickly and are automatically removed from the queue.
   • DIncrease the MaxDeliveryCount to a very high number so that the service will eventually process the message successfully without any special handling.

   • ACreate two topics: one for EU high-priority events and one for all other events.
   • BCreate one event subscription for both subscribers and have Subscriber A filter events in code.
   • CCreate one event subscription with a filter that includes all events except EU high-priority, and another for the rest.

   A company uses Azure Event Grid to deliver events to an Azure Function. The function sometimes fails due to a dependency that is unavailable for a few minutes. The team wants to ensure that events are retried with exponential backoff and that events that fail after all retries are stored for later analysis. They also want to minimize the number of events that are lost. What should they do?

   • ADisable dead-lettering to avoid extra storage costs and rely on the default retry policy.
   • BSet the retry policy to a maximum of 1 retry to avoid overloading the function.
   • CEnable dead-lettering on the event subscription and configure the retry policy to a maximum of 10 retries.
   • DUse a Service Bus queue as the event handler and have the function poll the queue.

   • AHave the clinic subscriber filter events after receiving all of them.
   • BPublish events to two separate custom topics, one for each subscriber.
   • CAdd a subject filter to the clinic subscriber's event subscription that matches the clinic ID in the event subject.
