Which information is used to calculate whether a WAN link has high usage?

Question

Options

• Adata under Security & SD WAN > Appliance Status > Uplink > Live Data
• Btotal historical throughput of an uplink
• Ctotal number of devices that are actively passing traffic
• Dvalue under Security & SD WAN > SD WAN & Traffic Shaping > Uplink Configuration

• B
  7% (2)
• C
  4% (1)
• D
  89% (25)

Explanation

Option D is correct because Meraki calculates WAN link "high usage" by comparing current throughput against the uplink capacity values configured under Security & SD-WAN > SD-WAN & Traffic Shaping > Uplink Configuration - without a defined capacity limit, the dashboard has no baseline to determine what "high" means. Option A (Live Data) shows real-time throughput but is not the reference point for the high-usage threshold calculation. Option B (total historical throughput) describes aggregate usage over time, not the capacity ceiling used for percentage-based alerting. Option C (number of active devices) is irrelevant - usage is measured in bandwidth consumed, not device count.

Memory tip: Think of it as a speedometer needing a speed limit sign - the configured uplink capacity (D) is the "speed limit" that makes "high usage" meaningful; without it, raw numbers have no context.
