NETCONF protocol provides a mechanism for managing network devices. It defines a series of operations. Which of the following descriptions of NETCONF operations is wrong?

Question

Options

• AThe <close-session> operation is used to forcefully end other NETCONF sessions and requires
• BThe <copy-config> operation is used to export the configuration, or completely replace one set of
• CThe <edit-config> operation is used to modify, create, and delete configuration data
• DThe <get-config> operation is used to query device configuration data

• A
  76% (13)
• B
  12% (2)
• C
  6% (1)
• D
  6% (1)

Explanation

Option A incorrectly describes <close-session> as forcefully ending other NETCONF sessions - that is actually the role of the <kill-session> operation, which requires administrator privileges to terminate another session by session ID. <close-session> only gracefully terminates the current session, cleanly releasing its locks and resources.

Options B, C, and D are all accurate: <copy-config> does copy or fully replace configuration datastores (e.g., candidate to running); <edit-config> does support create, merge, replace, and delete operations on configuration data; and <get-config> does retrieve configuration data from a specified datastore.

Memory tip: Think of the naming contrast - close is polite (close your own session gracefully), while kill is forceful (kill someone else's session). If a question mentions "forcefully" or "other sessions," the answer is always <kill-session>, never <close-session>.
