Refer to the exhibit.
All network links are FastEthernet. Although there is complete connectivity throughout the network,
Front Line users report that they experience slower network performance when accessing the
server farm than the Reception office experiences. Which two statements are true? (Choose two.)
A.
Changing the bridge priority of S1 to 4096 would improve network performance.
B.
Changing the bridge priority of S1 to 36864 would improve network performance.
C.
Changing the bridge priority of S2 to 36864 would improve network performance.
D.
Changing the bridge priority of S3 to 4096 would improve network performance.
E.
Disabling the Spanning Tree Protocol would improve network performance.
F.
Upgrading the link between S2 and S3 to Gigabit Ethernet would improve performance.
Explanation:
As the switch S1 has the better bridge priority it is selected as root bridge. As the consequence of
this the link between S2 and S3 is disabled and traffic from Front Line Users to Server Farm goes
through the root bridge S1. To improve network performance you have to make S2 or S3 to
become root bridge. You can do it by changing the bridge priority of S1 to 36864 or by changing
the bridge priority of S3 to 4096. In any case the traffic from Front Line Users to Server Farm will
go through the direct link between S2 and S3.
