Exam 300-115 Question id=1305 Layer 2 Technologies

What percentage of bandwidth is reduced when a stack cable is broken?

A. 0
B. 25
C. 50
D. 70
E. 100

The switches are physically connected sequentially, as shown in Figure 1. A break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. Subsecond timing mechanisms detect traffic problems and immediately institute failover. This mechanism restores dual path flow when the timing mechanisms detect renewed activity on the cable.
