- A
YANG: A data modeling language used to define configuration and state data for network devices.
YANG (Yet Another Next Generation) is a data modeling language that defines the structure, constraints, and semantics of data for network management protocols like NETCONF and RESTCONF.
- B
NETCONF: A network management protocol that uses XML-based RPCs to install, manipulate, and delete configuration data.
NETCONF uses XML-based RPCs (Remote Procedure Calls) over SSH, not HTTP. RESTCONF uses HTTP and supports both JSON and XML.
- C
RESTCONF: A RESTful protocol that uses HTTP methods and YANG-defined data models for network configuration.
RESTCONF uses HTTP (RESTful APIs) and supports both JSON and XML, not SSH. NETCONF uses SSH.
- D
YANG data model: A hierarchical schema that defines the structure and constraints of network configuration data.
YANG is a data modeling language, not a protocol. It defines the structure of data, but does not transport it. NETCONF and RESTCONF are the protocols that transport data.
Quick Answer
The correct answer pairs YANG with the hierarchical schema that defines network data structure and constraints, NETCONF with XML-based Remote Procedure Calls over SSH, and RESTCONF with HTTP-based access using YANG models. This mapping is accurate because YANG is a data modeling language that creates a structured, tree-like schema for configuration and state data, while NETCONF and RESTCONF are complementary protocols that use these models to manage devices—NETCONF through a secure, transaction-oriented SSH session and RESTCONF through stateless HTTP operations like GET and PATCH. On the CCNA 200-301 v2 exam, this drag-and-drop question tests your ability to distinguish the modeling language from the transport protocols, a common trap being confusion between NETCONF and RESTCONF since both rely on YANG. Remember the mnemonic: YANG is the blueprint, NETCONF is the secure builder (SSH), and RESTCONF is the web inspector (HTTP).
CCNA AI and Network Operations Practice Question
This 200-301 practice question tests your understanding of ai and network operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
YANG: A data modeling language used to define configuration and state data for network devices.
YANG is the modeling language, NETCONF uses XML RPCs over SSH, RESTCONF uses HTTP and YANG models. The pairs match each term to its core function.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 200-301 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.
