Drag and Drop Question Drag and drop the characteristics from the left onto the configuration protocols they describe on the right. Answer:

The correct answer is NETCONF: uses SSH transport; NETCONF: defined in RFC 6241; RESTCONF: uses HTTP transport; RESTCONF: defined in RFC 8040. The question assesses knowledge of NETCONF and RESTCONF configuration protocols, requiring the test-taker to match their correct transport mechanisms and defining RFCs.

Correct arrangement

NETCONF: uses SSH transport
NETCONF: defined in RFC 6241
RESTCONF: uses HTTP transport
RESTCONF: defined in RFC 8040

Explanation

The question assesses knowledge of NETCONF and RESTCONF configuration protocols, requiring the test-taker to match their correct transport mechanisms and defining RFCs.

Approach. The correct interaction is to drag the characteristics from the left panel to their respective protocol targets on the right. Specifically:

Drag 'uses SSH transport' to the NETCONF box. NETCONF primarily uses SSH as a secure transport layer.
Drag 'defined in RFC 6241' to the NETCONF box. RFC 6241 is the defining document for the NETCONF protocol.
Drag 'uses HTTP transport' to the RESTCONF box. RESTCONF is a REST-like protocol that leverages HTTP (or HTTPS) as its transport mechanism.
Drag 'defined in RFC 8040' to the RESTCONF box. RFC 8040 defines the RESTCONF protocol.

Common mistakes.

common_mistake. A common mistake would be to confuse the transport mechanisms or the RFCs between the two protocols. For instance, dragging 'uses HTTP transport' to NETCONF or 'uses SSH transport' to RESTCONF would be incorrect. This indicates a misunderstanding of how each protocol operates at the transport layer. Similarly, incorrectly associating the RFCs (e.g., 'defined in RFC 8040' with NETCONF) would show a lack of knowledge regarding the standardization documents for each protocol. Both protocols serve similar purposes (network configuration) but differ significantly in their underlying architectural styles and transport methods. Misplacing an RFC would mean the test-taker doesn't know the specific standard that defines each protocol.
incorrect_placement_example. Placing 'uses HTTP transport' under NETCONF is wrong because NETCONF uses SSH, while RESTCONF uses HTTP. Placing 'defined in RFC 6241' under RESTCONF is wrong because RFC 6241 defines NETCONF, not RESTCONF, which is defined by RFC 8040.

Concept tested. Network configuration protocols, specifically NETCONF and RESTCONF, including their transport layer mechanisms (SSH vs. HTTP) and their defining Request for Comments (RFC) standards.
