What are two characteristics of Cisco Catalyst Center (formerly DNA Center) and vManage northbound APIs? (Choose two.)

Question

Options

• AThey exchange XML-formatted content.
• BThey implement the RESTCONF protocol.
• CThey exchange JSON-formatted content.
• DThey implement the NETCONF protocol.
• EThey exchange protobut-formatted content.

• B
  95% (37)
• D
  3% (1)
• E
  3% (1)

Explanation

Explanation

Both Cisco Catalyst Center (DNA Center) and vManage use RESTCONF as their northbound API protocol (Option B), and RESTCONF natively uses JSON-formatted data (Option C) as its primary encoding format when communicating with external systems and orchestration tools.

Why the distractors are wrong:

• Option A (XML): While RESTCONF can support XML, JSON is the dominant and default format used by these Cisco platforms for northbound API communication.
• Option D (NETCONF): NETCONF is a southbound protocol used to configure network devices directly; it is not the northbound API protocol for these management platforms.
• Option E (Protobuf): Protocol Buffers (protobuf) is associated with gRPC/gNMI telemetry streaming, not RESTCONF-based northbound APIs.

Memory Tip: Think "REST goes NORTH with JSON" - RESTCONF is the northbound-facing API protocol for Cisco's management platforms (Catalyst Center, vManage), and JSON is its go-to data format. If you see NETCONF, think southbound device configuration; if you see gRPC/gNMI, think telemetry/protobuf.
