• Question 162:

  A network engineer proposes that old hubs be replaced by new Layer 2 switches in the company network. Which three are reasons for this proposal? (Choose three.)

  A. Each port on a switch becomes its own collision domain.
  B. Layer 2 switches provide IP routing at line card speed.
  C. Hubs create one large collision domain and one large broadcast domain, which greatly decreasing network performance.
