Click the Exhibit button.

Referring to the exhibit, which oversubscription ratio applies to Switch-3?

• A. 1:2
• B. 2:4
• C. 4:1
• D. 2:1

Answer: C

Explanation:
Switch-3 has 40 x 1 GbE (total 40 Gbps) access connections and 2 x 10 GbE uplinks (total 20 Gbps) to the distribution layer.
The oversubscription ratio is calculated as access bandwidth to uplink bandwidth:
40 Gbps / 10 Gbps per uplink × 2 = 40:10 = 4:1.
