Portfast, Root Guard, BPDU Filter and BPDU Guard Quiz
Please sign up for the
course
before taking this quiz.
1. Which states are bypassed with Portfast?
1
Listenning State
Blocking State
Learning State
Forwarding State
2. BPDU Filter removes Port Fast on the port, if it receives a BPDU packet. After that, it operates with normal STP
1
True
False
3. To configure a port with Root Guard, we use ….. command under the related interface.
2
spanning-tree root
spanning-tree guard root
stp root guard
stp guard
4. Why is STP Portfast used?
2
speed up convergence on port that other switches are connected
redundant connection on port that hosts are connected
redundant connection on port that other switches are connected
speed up convergence on port that hosts are connected
5. BPDU Guard is the mechanims that protect a port towards any BPDU
1
