.NET Core Microservices - Exchange Types

The video tutorial explains the concept of exchanges and queues in AMQP, focusing on four types of exchanges: direct, fanout, topic, and headers. Each exchange type has unique routing mechanisms, such as direct exchange using routing keys for one-to-one mapping, fanout exchange broadcasting messages to all queues, topic exchange using pattern matching, and headers exchange routing based on header attributes.

What is the primary role of an exchange in RabbitMQ?

• To encrypt messages for security

• To delete messages after a certain time

• To route messages to one or more queues

• To store messages permanently

Which type of exchange is best suited for sending a message to a single queue based on a routing key?

• Headers exchange

• Fanout exchange

• Direct exchange

• Topic exchange

How does a fanout exchange differ from a direct exchange?

• It uses routing keys for message delivery

• It uses message headers for routing

• It sends messages to all bound queues

• It requires a specific pattern for routing

What is a key feature of topic exchanges in RabbitMQ?

• They require message headers for routing

• They use patterns to match routing keys

• They ignore routing keys

• They store messages for future delivery

In a headers exchange, what determines the routing of messages?

• Exchange names

• Message headers

• Queue names

• Routing keys
