What would be an effect of this cable being disconnected?

Refer to the exhibit. A problem with network connectivity has been observed. It is suspected that
the cable connected to switch port Fa0/9 on Switch1 is disconnected. What would be an effect of
this cable being disconnected?

A.
For less than a minute, Host B would not be able to access the server in VLAN9. Then normal
network function would resume.

B.
Host B would not be able to access the server in VLAN9 until the cable is reconnected.

C.
The transfer of files from Host B to the server in VLAN9 would be significantly slower.

D.
Communication between VLAN3 and the other VLANs would be disabled.

Explanation:
Spanning-Tree Protocol (STP) is a Layer 2 protocol that utilizes a special-purpose algorithm to
discover physical loops in a network and effect a logical loop-free topology. STP creates a loopfree tree structure consisting of leaves and branches that span the entire Layer 2 network. The
actual mechanics of how bridges communicate and how the STP algorithm works will be
discussed at length in the following topics. Note that the terms bridge and switch are used

interchangeably when discussing STP. In addition, unless otherwise indicated, connections
between switches are assumed to be trunks.
STP keeps the port either in block or in forward states, when forward port disconnect then within
the less then a minute blocked port comes into forward state so packets starts to go through new
forward port.
The Spanning Tree Protocol (STP) would identify the best path as well as alternate path to reach
in proper destination. In a redundant link, if the primary link fails then the secondary links will
automatically start after few minutes. If port Fa0/9 became disconnected, then the packets would
be re-routed automatically using the Router-Switch2- Switch3 path.
