Refer to the exhibit. Which switch becomes the root of a spanning tree for VLAN 10 if the primary switch fails and all links are of equal speed?
The correct answer is C. SW3. Switch 2 is primary. But in this context, that is to say when it fails, the primary is chosen between SW1, SW3 and SW4. Thus, SW3 becomes the root.
