CCNA Routing and Switching (legacy) — Question 101

Which two statements about switch stacking are true? (Choose two)

Answer options

• A. The stack is powered by a single power cable
• B. The switches are connected in a daisy-chain fashion
• C. The first and last switch in the stack must be connected to one another
• D. The switches are connected by crossover cables
• E. The switches must be fully meshed

Correct answer: A, B

Explanation

Option A is correct because switch stacking typically requires only one power source for the entire stack. Option B is also correct as switches in a stack are usually connected in a daisy-chain configuration. Options C, D, and E are incorrect because the first and last switches do not need to be directly connected, crossover cables are not standard for stacking, and full meshing is not a requirement for switch stacks.
