The ability of one service to __________ another service forms the basis of service __________.

Question

Options

• Adivert, diversification
• Bregister, registries
• Cconsume, composition
• Dintegrate, integration

• A
  9% (2)
• B
  4% (1)
• C
  87% (20)

Explanation

Option C is correct because service composition is the architectural pattern where services are built by combining (consuming) other services - one service calls another's functionality to create higher-level capabilities. This is a foundational concept in SOA (Service-Oriented Architecture) and microservices design.

Why the distractors fail:

• A (divert/diversification): "Diverting" a service implies redirecting, not using it; "diversification" is a business/portfolio term with no SOA meaning.
• B (register/registries): While service registries exist in SOA, registering a service stores its metadata - it doesn't describe using one service from another.
• D (integrate/integration): "Integration" is plausible but describes connecting disparate systems broadly; it doesn't specifically capture the concept of one service depending on and invoking another to form a composite.

Memory tip: Think "consume = compose" - just like a recipe consumes ingredients to compose a dish, a composite service consumes component services to compose new functionality.
