- A
RESTCONF: A stateless, HTTP-based protocol that uses RESTful APIs and supports both XML and JSON data encoding.
This is correct because RESTCONF is a stateless protocol that uses HTTP methods (GET, POST, PUT, DELETE) and supports both XML and JSON encoding, making it suitable for RESTful API interactions.
- B
NETCONF: A stateful, RPC-based protocol that uses XML encoding and operates over SSH or TLS.
Why wrong: This is incorrect because NETCONF is indeed an RPC-based protocol that uses XML and operates over SSH or TLS, but it is stateful, not stateless. However, the description is accurate for NETCONF, but the question asks for the term that matches the description, and this description is for NETCONF, not RESTCONF.
- C
gRPC: A stateless, HTTP/2-based protocol that uses Protocol Buffers for data serialization.
Why wrong: This is incorrect because gRPC is a stateful protocol that uses HTTP/2 and Protocol Buffers, but it is not stateless; it supports streaming and bidirectional communication, which implies state.
- D
SSH: A stateless, secure shell protocol used for remote CLI access and file transfers.
Why wrong: This is incorrect because SSH is a stateful protocol that establishes a persistent, encrypted session for remote access and file transfers. It is not stateless.

This is incorrect because NETCONF is indeed an RPC-based protocol that uses XML and operates over SSH or TLS, but it is stateful, not stateless. However, the description is accurate for NETCONF, but the question asks for the term that matches the description, and this description is for NETCONF, not RESTCONF.

Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓RESTCONF: A stateless, HTTP-based protocol that uses RESTful APIs and supports both XML and JSON data encoding.Correct answer▾
Why this is correct
This is correct because RESTCONF is a stateless protocol that uses HTTP methods (GET, POST, PUT, DELETE) and supports both XML and JSON encoding, making it suitable for RESTful API interactions.
✗NETCONF: A stateful, RPC-based protocol that uses XML encoding and operates over SSH or TLS.Wrong answer — click to see why▾
Why this is wrong here
The description is accurate for NETCONF, but the question is about matching terms to descriptions, and this option describes NETCONF, not RESTCONF.
Why candidates choose this
Candidates might confuse NETCONF and RESTCONF, thinking both are stateless or that RESTCONF is stateful.
✗gRPC: A stateless, HTTP/2-based protocol that uses Protocol Buffers for data serialization.Wrong answer — click to see why▾
Why this is wrong here
gRPC is stateful, not stateless, due to its support for streaming and persistent connections.
Why candidates choose this
Candidates might think gRPC is stateless because it uses HTTP/2, but HTTP/2 itself is not stateless; gRPC maintains state for streams.
✗SSH: A stateless, secure shell protocol used for remote CLI access and file transfers.Wrong answer — click to see why▾
Why this is wrong here
SSH is stateful; it maintains session state (encryption keys, authentication) throughout the connection.
Why candidates choose this
Candidates might associate SSH with simple command execution and think it is stateless, but it actually maintains a session.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Be careful not to confuse RESTCONF (stateless) with NETCONF (stateful). Also, remember that gRPC and SSH are stateful protocols.
Detailed technical explanation
How to think about this question
Automation in Cisco networking relies heavily on APIs to configure, monitor, and manage devices efficiently. HTTPS (Hypertext Transfer Protocol Secure) serves as the secure transport layer, encrypting data between the client and server to protect sensitive network information during API calls. REST (Representational State Transfer) defines the interaction style or architectural pattern that uses standard HTTP methods like GET, POST, PUT, and DELETE to perform operations on network resources. JSON (JavaScript Object Notation) is the lightweight, human-readable data format used to structure the payloads exchanged in these API calls, enabling easy parsing and generation by network automation tools. Understanding the distinction between transport, interaction style, data format, and authentication is critical for CCNA candidates. HTTPS ensures secure communication channels, REST dictates how API endpoints are accessed and manipulated, JSON structures the data within those requests and responses, and tokens provide the authentication mechanism to control access to the network devices or controllers. Each component plays a unique role in the automation ecosystem, and Cisco network automation examples typically combine all four to achieve secure, scalable, and programmable network management. A common exam trap is confusing these terms as interchangeable or overlapping concepts. For example, mistaking REST for a transport protocol or JSON for an authentication method can lead to incorrect answers. In practical Cisco automation scenarios, HTTPS always secures the transport, REST defines the API interaction style, JSON formats the data, and tokens authenticate the session. Recognizing these distinct roles helps avoid errors and clarifies how automation frameworks like Cisco DNA Center or Cisco IOS XE APIs function in real-world network programmability.
KKey Concepts to Remember
- HTTPS provides a secure transport layer by encrypting API communication between clients and Cisco network devices.
- REST defines the interaction style using HTTP methods to manipulate network resources via APIs in Cisco automation.
- JSON structures the data payloads exchanged in API requests and responses for Cisco network programmability.
- Tokens act as credential-like values that authenticate and authorize access to Cisco network APIs.
- Cisco automation frameworks combine HTTPS, REST, JSON, and tokens to enable secure and programmable network management.
- Understanding the distinct roles of transport, interaction style, data format, and authentication prevents confusion in Cisco automation.
- REST APIs use standard HTTP methods, but HTTPS ensures the confidentiality and integrity of those API calls.
- Tokens are essential for controlling access and maintaining security in Cisco network automation environments.
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
HTTPS provides a secure transport layer by encrypting API communication between clients and Cisco network devices.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
