Which protocol is used for exchanging device information and faults in the SD-WAN management plane?

• A. Simple Network Message Protocol(SNMP)
• B. Simple Network Management Protocol(SNMP)
• C. Simple Network Protocol(SNMP)
• D. SNMP

Answer: (B)

In SD-WAN’s management plane, a standard protocol is used to gather device status and fault information from network devices. Simple Network Management Protocol enables a central manager to query devices (via GET requests) and to receive asynchronous alerts called traps when issues occur, all defined through MIBs (management information bases) that describe data like uptime, interface status, and fault indicators. This combination provides the visibility and alerting needed to monitor and troubleshoot the network effectively. The option that gives the full, correct name of the protocol matches what’s used in practice; the other choices either misstate the name or just give the acronym. So the protocol is Simple Network Management Protocol, i.e., SNMP.
