Refer to the exhibit. You want the performance service-level agreement (SLA) to measure the jitter of each member. Which configuration change must you make to achieve this result?

Question

Exhibits

Options

• ANo change is required.
• BAdd an SLA target and define a jitter threshold.
• CSpecify the participant members.
• DSet the protocol to HTTP.

• A
  88% (23)
• B
  4% (1)
• C
  8% (2)

Explanation

Implicit Measurement: In FortiOS, once a Performance SLA (Health Check) is configured with an Active probe mode (as seen in the exhibit with Ping selected), the FortiGate automatically begins calculating three key quality metrics for every member interface: Latency, Jitter, and Packet Loss. Visibility: Even without an SLA Target defined, these real-time measurements are visible in the SD- WAN Monitor and via the CLI command diagnose sys virtual-wan-link health-check Active Probes: Because the probe mode is set to Active using the Ping protocol, the FortiGate sends synthetic packets at the defined Check interval (500ms in the exhibit). It calculates jitter by measuring the variation in the round-trip time (RTT) between these consecutive probes.
