Which two benefits does BFD provide for failure detection? (Choose two.)

BFD (Bidirectional Forwarding Detection) is a lightweight, low-overhead protocol that quickly detects failures in the forwarding path between two routers. By detecting failures in milliseconds, BFD significantly speeds up routing convergence, allowing routing protocols to react faster to network changes and re-route traffic around failures. This rapid detection is a primary benefit. The other options are incorrect: BFD itself does not reduce memory and CPU usage; rather, its low overhead makes it efficient for rapid detection compared to the slower hello mechanisms of routing protocols. BFD does not provide fault tolerance by making multiple routers appear as a single virtual router; that is a function of protocols like HSRP or VRRP. BFD also does not allow peers to continue forwarding during a restart; it focuses on detecting forwarding path failures.
