Objective 3.7 · Domain 3 · 19% of the exam
Evaluate connection protocols and select the appropriate integration mechanism (MCP, API/CLI, agent-to-agent)
Choosing the connection mechanism, whether that is the Model Context Protocol, a direct API or CLI integration, or agent-to-agent communication. MCP is the answer when you want a standard, discoverable interface reusable across clients and tools. A direct API call is the answer when the integration is one-off, latency-critical or already built. Reach for agent-to-agent only when the other side genuinely needs autonomy, and not when it is a function you could call.
