STP Flashcards
(25 cards)
What does STP stand for in networking?
Spanning Tree Protocol
True or False: The Spanning Tree Protocol is used to prevent loops in a network.
True
What is the primary purpose of Spanning Tree Protocol?
To prevent broadcast storms and loops in Ethernet networks.
Fill in the blank: STP is a _____ layer protocol.
Data link
Which network topology does STP primarily work with?
Ethernet
What algorithm does STP use to determine the best path?
The Spanning Tree Algorithm
What is the role of the Bridge ID in STP?
To uniquely identify a bridge in the network.
Multiple Choice: Which of the following is NOT a state of a port in STP? A) Blocking B) Listening C) Forwarding D) Active
D) Active
What are the two main types of devices that participate in STP?
Bridges and switches
True or False: STP can only operate in a single VLAN.
False
What is the default bridge priority in STP?
32768
Fill in the blank: The _____ port is the port that has the lowest cost to the root bridge.
Root
What is the purpose of the Root Bridge in STP?
To serve as the central point of reference for path selection.
Multiple Choice: How often does a switch send Bridge Protocol Data Units (BPDUs)? A) Every second B) Every 2 seconds C) Every 30 seconds D) Every 5 seconds
B) Every 2 seconds
What happens to a port in the Blocking state?
It does not forward frames and listens for BPDUs.
What is the purpose of the Listening state in STP?
To prepare to forward frames while still preventing loops.
What is the maximum number of switches that can be part of a single STP instance?
There is no strict maximum, but practical limits depend on network design.
True or False: Rapid Spanning Tree Protocol (RSTP) is an evolution of STP.
True
What is the primary benefit of using RSTP over traditional STP?
Faster convergence times.
Fill in the blank: The _____ cost is used to determine the best path to the root bridge.
Path
What is a Designated Port in STP?
The port on a network segment that has the lowest path cost to the root bridge.
What does the term ‘convergence’ refer to in STP?
The process of all switches agreeing on the network topology.
True or False: STP is only applicable to Layer 2 networks.
True
What protocol does STP use to communicate between switches?
Bridge Protocol Data Units (BPDUs)
