• B. The highest root bridge identifier is preferred over lower root bridge identifiers.
• C. The lowest root bridge priority is preferred over higher root bridge priorities.

Correct answer: C, D

Explanation

The correct answers are C and D because, during the root bridge election, the switch with the lowest bridge priority is selected as the root bridge.
