300-435 Question 59
Single answerAn enterprise network engineer is evaluating management protocols for automating their network configurations. The engineer needs a protocol that supports a standardized data modeling language, can handle large data payloads efficiently, and provides mechanisms for both configuration and state retrieval. Which protocol would best meet these requirements?
- A
NETCONF
- B
RESTCONF
- C
SNMP
- D
gRPC
Show answer and explanation
Correct answer: A
Explanation
NETCONF is the best choice for this scenario because it is specifically designed for network management tasks, including configuration and state retrieval. It supports YANG data models, which are widely used in modern network automation, and uses XML encoding over SSH, making it efficient for handling large data payloads. RESTCONF is a close alternative but is better suited for simpler, RESTful API interactions.
- A. Correct.
NETCONF is specifically designed for managing network devices with features like configuration and state retrieval, support for YANG data models, and efficient handling of large data payloads using XML over SSH.
- B. Incorrect.
RESTCONF also supports YANG data models and is useful for RESTful APIs but is less efficient than NETCONF for handling large data payloads due to its reliance on HTTP and JSON or XML encoding.
- C. Incorrect.
SNMP is primarily used for monitoring network devices and does not support modern data modeling languages like YANG. It is not suitable for complex configuration tasks.
- D. Incorrect.
gRPC is a high-performance RPC framework but is not natively designed for network configuration and lacks standardized support for YANG data models.
