A branch office uses both MPLS and Broadband. The design requires that business-critical traffic prefers MPLS, failing over to Broadband only if the MPLS path experiences packet loss exceeding 1%. Which metric should the PFR policy utilize?
Trap 1: Bandwidth Utilization
Bandwidth is for congestion, not loss-based failover.
Trap 2: Jitter
Jitter is a metric, but the requirement specifically mentions packet loss.
Trap 3: Round Trip Time (RTT)
RTT measures latency, not packet loss.
- A
Bandwidth Utilization
Why wrong: Bandwidth is for congestion, not loss-based failover.
- B
Packet Loss
This is the specific metric to trigger the failover based on the 1% threshold.
- C
Jitter
Why wrong: Jitter is a metric, but the requirement specifically mentions packet loss.
- D
Round Trip Time (RTT)
Why wrong: RTT measures latency, not packet loss.
