Final answer:
WANDL collects live network information using SNMP, a protocol for network monitoring and management that enables the gathering of device status and traffic data.
Step-by-step explanation:
WANDL, or Wide Area Network Design Laboratory, uses SNMP (Simple Network Management Protocol) to collect live network information. This protocol is widely used for network management and monitoring purposes. SNMP provides a standardized framework for network devices to report data on their status and for management systems to control their configurations. WANDL may use this protocol to poll routers and switches for their live operational statistics, which can include various forms of data such as traffic flow, link utilization, and device status.
