Question 1

What is the key difference between an Azure Service Bus queue and a topic?

Accepted Answer

Topics support multiple subscriptions allowing multiple consumers to receive copies of each message, while queues deliver each message to exactly one consumer

Answer

Topics implement a publish-subscribe pattern where multiple subscriptions each receive a copy of every message, while queues implement point-to-point delivery where each message goes to exactly one consumer.

Question 2

Which Azure SDK method should you call to settle a received Service Bus message and confirm it was successfully processed, preventing redelivery?

Accepted Answer

CompleteMessageAsync()

Answer

CompleteMessageAsync() settles a received Service Bus message, removing it from the queue or subscription and preventing it from being redelivered to another consumer.

Question 3

What is the purpose of Azure Event Hubs Capture?

Accepted Answer

To automatically archive streaming data to Azure Blob Storage or Azure Data Lake Storage

Answer

Event Hubs Capture automatically captures streaming data and persists it to Azure Blob Storage or Azure Data Lake Storage for batch processing or long-term analytics without requiring additional code.

Question 4

Which Service Bus feature allows you to atomically send or receive messages across multiple queues and topics in a single all-or-nothing operation?

Accepted Answer

Transactions

Answer

Azure Service Bus supports transactions that enable atomic operations across multiple messaging entities, ensuring all operations either succeed or fail together.

Question 5

In Azure Event Hubs, what happens when events are published with the same partition key?

Accepted Answer

A hash of the partition key routes all matching events consistently to the same partition

Answer

When a partition key is specified, Event Hubs hashes the key to consistently route events with the same key to the same partition, ensuring ordered delivery for related events.
