Which two statements are correct about Layer 3 fast convergence? (Choose two.)

A routed physical interface signals a Layer 3 failure immediately upon detecting a Layer 1 or Layer 2 carrier loss, whereas an SVI must wait for all associated physical ports in its VLAN to go down and for the VLAN to become inactive before the Layer 3 state changes, adding measurable delay to convergence.

Lowering hello and dead interval timers causes routing protocols to transmit and process keepalive messages more frequently across all participating neighbors, directly increasing the CPU cycles consumed by the routing process on every router in the domain.

Physical link-down signals at Layer 1 and carrier-loss detection at Layer 2 are faster than Layer 3 protocol-based detection, which depends on timer expiration - this statement reverses the actual order of detection speed.

Interface dampening suppresses route advertisements for flapping interfaces by applying an exponential penalty and hold-down period, which delays convergence rather than improving it, and conflicts with the goal of aggressively low routing timers.

The physical cable medium type does not meaningfully affect Layer 3 convergence time at typical LAN and WAN distances because convergence speed is governed by protocol timer values and failure detection logic, not the signal propagation difference between fiber and UTP.
