Which three statements about STP timers are true?()
- ASTP timers values (hello, forward delay, max age) are included in each BPDU.
- BA switch is not concerned about its local configuration of the STP timers values. It will only consider the value of the STP timers contained in the BPDU it is receiving.
- CTo successfully exchange BPDUs between two switches, their STP timers value (hello, forward delay, max age) must be the same.
- DIf any STP timer value (hello, forward delay, max age) needs to be changed, it should at least be changed on the root bridge and backup root bridge.
- EOn a switched network with a small network diameter, the STP hello timer can be tuned to a lower value to decrease the load on the switch CPU.
- FThe root bridge passes the timer information in BPDUs to all routers in the Layer 3 configuration.
