  1. Which Azure messaging service supports SQL-like filter rules on subscriptions to selectively receive only relevant messages from a topic?

    Answer: Azure Service Bus Topics

    Azure Service Bus topic subscriptions support SQL filter expressions and correlation filters to selectively route only matching messages to specific subscriptions.

  2. What is the maximum event retention period supported by Azure Event Hubs Standard tier?

    Answer: 7 days

    Azure Event Hubs Standard tier supports event retention for up to 7 days, with a default of 1 day; Premium and Dedicated tiers support longer retention periods.

  3. Which Azure Event Grid schema is based on the CNCF CloudEvents 1.0 specification for cross-platform event interoperability?

    Answer: CloudEvents Schema

    Azure Event Grid supports the CloudEvents 1.0 schema, the CNCF open standard that provides a common format for describing event data across platforms and cloud providers.

  4. In Azure Queue Storage, what time-to-live (TTL) value should you set to allow a message to persist indefinitely without expiring?

    Answer: -1 (infinite TTL)

    Setting the message TTL to -1 in Azure Queue Storage configures the message for infinite retention, meaning it will never expire automatically.

  5. When using the Azure.Messaging.ServiceBus SDK, which class provides a higher-level message pump that continuously processes messages and automatically renews message locks?

    Answer: ServiceBusProcessor

    ServiceBusProcessor provides a higher-level API that continuously receives messages, invokes registered handlers, and automatically renews message locks while processing is in progress.

  6. What is the maximum message size supported by Azure Service Bus Premium tier?

    Answer: 100 MB

    Azure Service Bus Premium tier supports messages up to 100 MB in size, a significant increase over the 256 KB limit of the Standard tier, making it suitable for larger payloads.

  7. Which Azure Service Bus feature allows a receiver to postpone processing a message so it can be retrieved later by its sequence number, without dead-lettering it?

    Answer: Message deferral

    Message deferral allows a receiver to postpone a message without dead-lettering it; the message stays in the queue in a deferred state and can be retrieved explicitly using its sequence number.
