If you want to disable STP on a port connected to a server, which command would you use?
A. disable spanning-tree
B. spanning-tree off
C. spanning-tree security
D. spanning-tree portfast
Answer: Option D
Solution(By Examveda Team)
If you have a server or other devices connected into your switch that you're totally sure won't create a switching loop if STP is disabled, you can use something calledportfast on these ports. Using it means the port won't spend the usual 50 seconds to come up while STP is converging. This Question Belongs to Networking >> Spanning Tree Protocol

What is the purpose of Spanning Tree Protocol in a switched LAN?
A. To provide a mechanism for network monitoring in switched environments
B. To prevent routing loops in networks with redundant paths
C. To prevent switching loops in networks with redundant switched paths
D. To manage the VLAN database across multiple switches
E. To create collision domains
Which statement describes a spanning-tree network that has converged?
A. All switch and bridge ports are in the forwarding state.
B. All switch and bridge ports are assigned as either root or designated ports.
C. All switch and bridge ports are in either the forwarding or blocking state.
D. All switch and bridge ports are either blocking or looping.
A. Forwards the switch to the first available link
B. Drops the frame
C. Floods the network with the frame looking for the device
D. Sends back a message to the originating station asking for a name resolution
A. During high-traffic periods
B. After broken links are reestablished
C. When upper-layer protocols require high reliability
D. In an improperly implemented redundant topology
Port fast does not disable spanning tree on a port. this is a very common misnomer. the port still receives and learns BPDU with port fast enabled. the only thing port fast does is accelerate my transition from blk to fwd.
