Exam 350-901 topic 1 question 214 discussion

B is correct

Correcft answer: B Patch = update Post = create or operation like reload GET = Read PATCH = Update PUT = Create or Replace POST = Create or Operations (reload, default) DELETE = Deletes the targeted resource HEAD = Header metadata (no response body) https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/168/b_168_programmability_cg/RESTCONF.pdf

B is correct since the question is asking to change an existing value (from 192.168.100.1/24 to 10.10.10.1/24) The following table shows how the RESTCONF operations relate to NETCONF protocol operations: GET = Read PATCH = Update PUT = Create or Replace POST = Create or Operations (reload, default) DELETE = Deletes the targeted resource HEAD = Header metadata (no response body)

POST creates new records. PUT/PATCH updates/partially-updates existing records (meaning it performs a CHANGE). Since the question wants to CHANGE a value on something that exists, than it can only be B - PATCH

I agree with PATCH because of the Cisco Study Guide DEVCOR 350-901

Regarding to the Cisco DEVCOR 350-091 Study Guide Page 138, the Answer should be B. PATCH.

HTTPs Methods The https-based protocol-RESTCONF (RFC 8040), which is a stateless protocol, uses secure HTTP methods to provide CREATE, READ, UPDATE and DELETE (CRUD) operations on a conceptual datastore containing YANG-defined data, which is compatible with a server that implements NETCONF datastores. The following table shows how the RESTCONF operations relate to NETCONF protocol operations: OPTIONS SUPPORTED METHODS GET Read PATCH Update PUT Create or Replace POST Create or Operations (reload, default) DELETE Deletes the targeted resource HEAD Header metadata (no response body) https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/166/b_166_programmability_cg/restconf_prog_int.pdf
