300-435 Question 81
Select 2You are tasked with automating the configuration of an IOS XE device in your enterprise network. Which of the following transport protocols and technologies must be enabled on the IOS XE device to allow programmatic access and configuration via RESTCONF?
- A
NETCONF
- B
HTTP/HTTPS
- C
REST API
- D
YANG data models
- E
SSH
Show answer and explanation
Correct answers: B, D
Explanation
RESTCONF is a protocol used for automating configuration and operational tasks on Cisco IOS XE devices. To enable RESTCONF, you must ensure that HTTP or HTTPS is enabled on the device as the transport protocol. Additionally, RESTCONF relies on YANG data models to define the structure of the data being accessed and configured. While other protocols like NETCONF and SSH are useful for automation, they are not required for RESTCONF.
- A. Incorrect.
NETCONF is used for network device configuration and management, but it is not directly required for RESTCONF operations. RESTCONF relies on HTTP/HTTPS instead.
- B. Correct.
HTTP/HTTPS is the primary transport protocol for RESTCONF. It allows communication between the client and the server for RESTCONF requests and responses.
- C. Incorrect.
REST API is a concept, not a transport protocol. RESTCONF uses HTTP/HTTPS as a transport protocol and relies on YANG data models for the API structure.
- D. Correct.
YANG data models define the structure and syntax for configuration and operational data, making them essential for RESTCONF operations on IOS XE devices.
- E. Incorrect.
SSH is used for secure remote access and is necessary for NETCONF over SSH, but it is not required for RESTCONF, which uses HTTP/HTTPS for transport.
