200-901 Question #206: Real Exam Question with Answer & Explanation

Question

What is a benefit of model-driven programmability?

Options

• AIt addresses the static architecture of traditional networks being decentralized and complex.
• BBy modeling data, it ensures that vast quantities of data are usable for monitoring.
• CIt provides a programmatic and standards-based way of writing configurations to any network
• DIt simplifies management and operations by decoupling the networking hardware from its control

Explanation

{"question_number": 10, "question": "What is a benefit of model-driven programmability?", "correct_answer": "C", "explanation": "Model-driven programmability (using data models like YANG with protocols like NETCONF and RESTCONF) provides a standardized, programmatic, vendor-agnostic method for configuring any network device. This means configurations can be written consistently across different vendors' equipment. Option A incorrectly describes the problem (traditional networks are decentralized, but model-driven programmability doesn't directly fix centralization). Option B is about data monitoring at scale, which is not the primary benefit. Option D describes Software-Defined Networking (SDN), which decouples the control plane from hardware - a distinct concept from model-driven programmability.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
