200-901 Infrastructure and Automation Practice Question
Which TWO of the following are true about NETCONF capabilities as defined in RFC 6241?
⚠ Common exam trap
Cisco often tests the distinction between mandatory and optional capabilities, and the default operation of <edit-config>, to catch candidates who confuse 'merge' with 'replace' or assume all datastores are optional.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The <edit-config> operation supports 'merge', 'replace', 'create', 'delete', and 'remove' operations.
RFC 6241 defines the <edit-config> operation with the 'merge', 'replace', 'create', 'delete', and 'remove' operations. These allow granular modification of configuration data, with 'merge' being the default behavior if no operation attribute is specified.
