Which of the following ports will forward Ethernet frames? (Choose two.)
Designated port
Blocked port or non-dedicated port
Root port
How often does a switch send a BPDU?
Every 2 seconds
Every 15 seconds
Every 20 seconds
Only when there is a change in the topology
The port on the segment (with two switches) that has the lowest path cost to the root bridge is the:
Designated port
Blocked port or non-designated port
Root port
Routed Port
The port closest to the root bridge in terms of least overall cost (best path) to the root bridge is the:
Designated port
Blocked port or non-designated port
Root port
Routed Port
The root bridge will be the switch with the:
Lowest bridge ID
Highest bridge ID
Lowest port priority
Highest port priority
The sum of individual port costs along the path from the switch to the root bridge is known as the:
Least cost path
Shortest path cost
Best path cost
Root path cost
By default (without any configuration on a switch), what will determine which switch is the root bridge?
The bridge priority
The extended system ID
The MAC address of the switch
The bridge ID
Which statement describes STP?
STP is a Layer 2 routing protocol.
STP is a Layer 3 routing protocol for Ethernet LANs.
STP is a Layer 2 loop prevention protocol for Ethernet LANs.
STP is a Layer 3 loop prevention protocol for IP networks.
Without STP on the Ethernet LAN, which three types of frames could NOT cause a catastrophic loop in the network?
Unicast
Unknown unicast
Multicast
Broadcast
