- A
Ansible: An agentless automation tool that uses SSH and YAML playbooks for configuration management.
This is correct because Ansible is indeed agentless, uses YAML for its playbooks, and executes tasks over SSH without requiring any agent software on managed nodes.
- B
Puppet: A configuration management tool that uses a declarative language and a client-server model with agents.
This is incorrect because while Puppet does use a declarative DSL and master-agent architecture, the description is actually accurate for Puppet. However, the question asks to match each term to its description, and this option is a distractor that is correct for Puppet but not for the term being matched (which is not specified here). In the context of the question, the correct answer is A, and B is a plausible distractor because it describes a different tool accurately.
- C
Chef: An automation tool that uses Ruby-based recipes and cookbooks for infrastructure configuration.
This is incorrect because while Chef does use Ruby and a master-agent model, the description is accurate for Chef. However, the correct answer for the term being matched is A. This option is a distractor that correctly describes Chef but does not match the term in question.
- D
SaltStack: A remote execution and configuration management tool that uses a master-minion architecture.
This is incorrect because while SaltStack does use remote execution via ZeroMQ and can operate in both modes, the description is accurate for SaltStack. However, the correct answer for the term being matched is A. This option is a distractor that correctly describes SaltStack but does not match the term in question.
CCNA AI and Network Operations Practice Question
This 200-301 practice question tests your understanding of ai and network operations. 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. A key principle to apply: jSON is a lightweight, structured data format used to represent network information in a human-readable and machine-parsable way.. 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.

Correct answer & explanation
Ansible: An agentless automation tool that uses SSH and YAML playbooks for configuration management.
JSON is a lightweight data-interchange format commonly used to structure API request and response payloads. REST is an architectural style that uses HTTP methods to enable stateless interactions between software systems. An API is a defined set of rules and protocols that allows different software applications to communicate with each other. YANG is a data modeling language specifically designed to model configuration and state data for network devices, often used with NETCONF and RESTCONF.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The most common mistake is confusing YANG with data serialization formats like JSON or XML; candidates misidentify YANG as a data format rather than a modeling language used to describe network information structures.
Detailed technical explanation
How to think about this question
Automation in Cisco networking relies on clear distinctions between data formats, transport methods, interfaces, and data models. JSON (JavaScript Object Notation) is a lightweight, human-readable data format used to represent structured data. It is widely used in network automation for exchanging configuration and state information because it is easy to parse and generate. REST (Representational State Transfer) is an architectural style that uses standard HTTP methods like GET, POST, PUT, and DELETE to interact with resources, making it a popular choice for network device communication. An API (Application Programming Interface) defines the set of rules and protocols that allow different software applications to communicate. In network automation, APIs expose device capabilities and data to automation tools. YANG is a specialized data modeling language designed to describe the structure and semantics of network configuration and state data. It provides a standardized way to model network elements, enabling consistent automation across diverse devices. Understanding these distinctions is critical in the CCNA context because automation questions test your ability to recognize each term’s role rather than deep programming knowledge. Confusing JSON with YANG or REST with API leads to incorrect answers. Practically, network engineers use YANG models to define device data, JSON to encode that data, REST APIs to transport it, and APIs as the interface to access device functions. This layered approach is foundational for modern Cisco network automation.
KKey Concepts to Remember
- JSON is a lightweight, structured data format used to represent network information in a human-readable and machine-parsable way.
- REST is an architectural style that uses HTTP methods to enable stateless communication between clients and network devices.
- An API defines the interface and protocols that allow software systems to interact and exchange data in network automation.
- YANG is a data modeling language that describes the structure and semantics of network configuration and operational data.
- Network automation relies on JSON for data encoding, REST for transport, APIs for interaction, and YANG for data modeling.
- Confusing data formats like JSON with data models like YANG is a common mistake in CCNA automation questions.
- REST APIs use HTTP methods such as GET, POST, PUT, and DELETE to perform operations on network device resources.
- YANG models enable consistent and vendor-neutral descriptions of network device configurations for automation tools.
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
JSON is a lightweight, structured data format used to represent network information in a human-readable and machine-parsable way.
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. JSON is a lightweight, structured data format used to represent network information in a human-readable and machine-parsable way. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
