Answer: C

Explanation:

Physical Sequential Linkage The switches are physically connected sequentially, as shown in Figure 3. 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. Figure 3. Cisco StackWise Technology Resilient Cabling
