d) A managed database service for storing and querying messages
The correct answer is c) A topic-based mechanism for broadcasting messages to multiple subscribers.
Explanation: In Azure Service Bus, a topic is a publish-subscribe mechanism that allows messages to be broadcast to multiple subscribers. Publishers send messages to a topic, and subscribers can choose to receive messages based on specific subscription rules.
Question 4: What is the purpose of message sessions in Azure Service Bus?
a) They enable grouping related messages together for processing
b) They ensure exactly-once delivery of messages
c) They provide ordered delivery of messages within a session
d) They enable real-time streaming of messages between services
The correct answer is a) They enable grouping related messages together for processing.
Explanation: Message sessions in Azure Service Bus allow related messages to be grouped together and processed as a unit. This is useful when messages need to be processed in a specific order or when there is a dependency between multiple messages.
Question 5: How does Azure Service Bus ensure message reliability?
a) It provides message duplication detection and deduplication
b) It guarantees in-order delivery of messages
c) It supports exactly-once message delivery semantics
d) It provides high-throughput streaming of messages
The correct answer is a) It provides message duplication detection and deduplication.
Explanation: Azure Service Bus ensures message reliability by providing built-in features for detecting and eliminating duplicate messages. It provides mechanisms for identifying duplicate messages based on message deduplication IDs, ensuring that each message is processed only once.
