CCNA - SRWE - 5.2.12

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.

The root bridge will be the switch with the:

• Lowest bridge ID

• Highest bridge ID

• Lowest port priority

• Highest port priority

The port closest to the root bridge in terms of least overall cost (best path) to the root bridge is the:

• Designed port

• Blocked port or non-designated port

• Root port

• Routed port

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

Which of the following ports will forward Ethernet frames? (Choose two.)

• Designated port

• Blocked port or non-dedicated port

• Root port

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

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
