Which statement describes the term bridge priority in the operation of STP?

  • It is a value that decides which switch can become the root bridge.
  • It is a value that is used, in the event of a loop, to decide which port on the switch must be put into forwarding state.
  • It is a safety mechanism that shuts down ports configured with STP portfast upon receipt of a BPDU.
  • It is a feature that prevents any alternative or root ports from becoming designated ports because of a loss of BPDUs on the root port.
Explanation & Hints:

The statement that describes the term bridge priority in the operation of STP (Spanning Tree Protocol) is:

  • It is a value that decides which switch can become the root bridge.

Explanation:

Bridge priority is a component of the bridge ID used in STP to elect the root bridge. The bridge ID consists of a bridge priority value and the MAC address of the switch. The switch with the lowest bridge ID (which considers both the priority and MAC address) becomes the root bridge in the spanning tree topology. The default priority value can be adjusted to influence which switch is more likely to be elected as the root bridge, allowing network administrators to control the layout of the spanning tree for efficiency and optimization of network traffic.
