Integration Patterns - Quiz #1

Which integration pattern involves a direct, dedicated connection between two systems?

• Broker

• Publish-Subscribe

• Point-to-Point

• Mediator

A primary disadvantage of the Point-to-Point integration pattern is that it leads to a "spaghetti" architecture when:

• Systems are highly decoupled.

• The number of integrated systems is small.

• Many systems need to connect to each other.

• Data transformation is not required.

Which pattern uses a central intermediary to facilitate communication between multiple systems, reducing direct connections?

• Point-to-Point

• Broker

• Adapter

• Proxy

In the Publish-Subscribe (Pub/Sub) pattern, what is the role of a "publisher"?

• To request data from a subscriber.

• To store messages for later retrieval.

• To send messages without knowing who the receivers are.

• To directly call a subscriber's service.

Which integration pattern is best suited for scenarios requiring highly decoupled, asynchronous communication where senders don't need to know about receivers?

• Point-to-Point

• Broker

• Publish-Subscribe

• Mediator

The Mediator pattern is primarily used to:

• Establish direct connections between two systems.

• Convert the interface of a class into another interface clients expect.

• Orchestrate interactions among multiple components to avoid direct coupling.

• Provide a surrogate or placeholder for another object to control access to it.

An Adapter pattern's main purpose in system integration is to:

• Centralize all communication logic.

• Make incompatible interfaces work together.

• Broadcast messages to multiple consumers.

• Monitor system performance.

Which pattern is useful when you want to control access to a service, add logging, or provide a simplified interface to a complex subsystem?

• Mediator

• Adapter

• Proxy

• Publish-Subscribe

Consider a scenario where a legacy system uses an outdated data format, and a modern system needs to consume its data. Which pattern would most directly address the data format incompatibility?

• Mediator

• Adapter

• Proxy

• Broker

A system where a central component manages the complex workflow involving several other independent services, ensuring they interact in a specific sequence, is likely using which pattern?

• Point-to-Point

• Proxy

• Adapter

• Mediator
