An administrator is configuring an ION 2000 device for a deployment where high availability is required, but the site has only a single internet circuit. The administrator configures a Bypass Pair (Fail-to-Wire) on ports 1 and 2 connecting the ISP modem to the legacy firewall. If the ION device loses power, what is the resulting behavior of the traffic flowing through this Bypass Pair?
Correct Answer: B
Comprehensive and Detailed Explanation The Bypass Pair feature on Prisma SD-WAN ION devices (specifically supported models like ION 2000, 3000, 7000, 9000) is a hardware-based resiliency mechanism known as Fail-to-Wire. * Operation: A "Bypass Pair" logically groups two physical interfaces (e.g., WAN 1 and LAN 1). Under normal operation, the ION processes traffic between them. * Power Loss: In the event of a total power loss (or critical software failure), a mechanical relay inside the device physically closes the circuit between the two ports. * Result: This creates a direct electrical connection (like a patch cable) between the upstream device (ISP Modem) and the downstream device (Legacy Firewall or Router). This ensures that internet connectivity is preserved for the site, even if the SD-WAN appliance is completely dead. This is critical for single-point-of-failure deployments where maintaining basic dial-tone is more important than SD- WAN optimization during a hardware outage.
