Based on the network shown in the graphic which option contains both the potential networking
problem and the protocol or setting that should be used to prevent the problem?
A.
switching loops, VTP
B.
switching loops, STP
C.
routing loops, split horizon
D.
routing loops, hold down timers
E.
switching loops, split horizon
F.
routing loops, STP
Explanation:
The Spanning-Tree Protocol (STP) prevents loops from being formed when switches or bridges
are interconnected via multiple paths. Spanning-Tree Protocol implements the 802.1D IEEE
algorithm by exchanging BPDU messages with other switches to detect loops, and then removes
the loop by shutting down selected bridge interfaces. This algorithm guarantees that there is one
and only one active path between two network devices.
