PCNSE Question #492: Real Exam Question with Answer & Explanation
The correct answer is C: SD-WAN Interface profile. Forward Error Correction (FEC) is a technique that proactively adds redundant data to packets so that the receiver can reconstruct lost packets without retransmission, improving performance over lossy WAN links. In PAN-OS SD-WAN, FEC is configured within the SD-WAN Interface Prof
Question
When configuring forward error correction (FEC) for PAN-OS SD-WAN, an administrator would turn on the feature inside which type of SD-WAN profile?
Options
- ACertificate profile
- BPath Quality profile
- CSD-WAN Interface profile
- DTraffic Distribution profile
Explanation
Forward Error Correction (FEC) is a technique that proactively adds redundant data to packets so that the receiver can reconstruct lost packets without retransmission, improving performance over lossy WAN links. In PAN-OS SD-WAN, FEC is configured within the SD-WAN Interface Profile (also referred to as the Link profile or SD-WAN Interface profile), which defines per-link characteristics such as link tags, FEC, and packet duplication settings. The Path Quality Profile defines SLA thresholds (latency, jitter, packet loss) used for path selection. The Traffic Distribution Profile defines how traffic is load-balanced across links. Certificate profiles are unrelated to SD-WAN link configuration.
