Which two statements correctly describe a RESTful API used by network controllers? Choose two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
It commonly uses HTTP methods such as GET and POST
That is a core part of REST-style APIs.
B
Distractor review
It requires SNMP traps for every successful request
REST does not depend on SNMP.
C
Best answer
It is typically stateless between client requests
Each request stands on its own in a stateless API design.
D
Distractor review
It can only return XML, never JSON
JSON is extremely common with REST APIs.
Common exam trap
Common exam trap: answer the scenario, not the keyword
A common exam trap is to incorrectly associate RESTful APIs with SNMP traps or assume REST APIs require stateful communication. Some candidates mistakenly believe that RESTful APIs depend on SNMP for notifications or that they can only return XML data. This confusion arises because SNMP is a traditional network management protocol that uses traps and stateful sessions, unlike REST. Selecting options that imply RESTful APIs need SNMP traps or cannot use JSON leads to incorrect answers. Recognizing that RESTful APIs are stateless and commonly use JSON prevents this mistake.
Technical deep dive
How to think about this question
RESTful APIs are a set of architectural principles used to design network controller interfaces that communicate over HTTP. They use standard HTTP methods such as GET, POST, PUT, PATCH, and DELETE to perform operations on network resources. This design allows clients to interact with network devices and controllers in a uniform, predictable way, enabling automation and programmability in Cisco networks. A key characteristic of RESTful APIs is their statelessness, meaning each client request contains all the information needed for the server to process it without relying on stored context from previous requests. This stateless design simplifies scalability and reliability in network automation, as the server does not need to maintain session information between requests. A common exam trap is to confuse RESTful APIs with other network management protocols like SNMP, which uses traps and stateful communication. REST APIs do not require SNMP traps and can return data in multiple formats, including JSON and XML. Understanding these distinctions helps avoid selecting incorrect options related to protocol dependencies or data formats in the CCNA exam context.
KKey Concepts to Remember
- RESTful APIs use standard HTTP methods such as GET, POST, PUT, PATCH, and DELETE to interact with network controllers and devices.
- A RESTful API is stateless, meaning each request from a client must contain all information needed for the server to process it independently.
- Network controllers use RESTful APIs to enable automation and programmability by providing a uniform interface for configuration and monitoring.
- RESTful APIs commonly return data in JSON format, which is lightweight and widely supported in network automation tools.
- RESTful APIs do not rely on SNMP traps or any stateful communication mechanisms to confirm successful requests.
- Statelessness in RESTful APIs improves scalability and fault tolerance in network management systems by avoiding session dependencies.
- HTTP methods in RESTful APIs correspond to CRUD operations: GET retrieves data, POST creates resources, PUT updates resources, and DELETE removes resources.
- Understanding the stateless nature and HTTP method usage of RESTful APIs helps avoid confusion with other network management protocols in the CCNA exam.
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.

FAQ
Questions learners often ask
What does this 200-301 question test?
RESTful APIs use standard HTTP methods such as GET, POST, PUT, PATCH, and DELETE to interact with network controllers and devices.
What is the correct answer to this question?
The correct answer is: It commonly uses HTTP methods such as GET and POST — REST commonly uses HTTP methods such as GET, POST, PUT, PATCH, and DELETE. It is also stateless, which means each request includes the information needed for the server to process it.
