Question 912 of 1,000
200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which YANG model is an OpenConfig model used for interface configuration?

Correct answer & explanation
✓
openconfig-interfaces
OpenConfig is a vendor-neutral, community-driven data model standard for network configuration and state. The 'openconfig-interfaces' YANG model is the OpenConfig model specifically designed for interface configuration, providing a consistent, model-driven approach across different network operating systems. Option D is correct because it directly names the OpenConfig model for interfaces.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between vendor-neutral OpenConfig models, IETF standard models, and Cisco proprietary native models, expecting candidates to recognize that 'openconfig-interfaces' is the correct OpenConfig model name, not a generic or IETF-prefixed alternative.
Detailed technical explanation
How to think about this question
OpenConfig models are defined in a public GitHub repository and use a consistent naming convention (e.g., 'openconfig-interfaces', 'openconfig-bgp'). They are designed to be vendor-agnostic, allowing multi-vendor network automation with tools like NETCONF or gNMI. In contrast, IETF models (like 'ietf-interfaces') are standards-track but often less feature-rich for operational state, while native models (like 'Cisco-IOS-XE-interfaces') expose platform-specific capabilities but lock you into a single vendor.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
