Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 53

You have a Cisco UCS Fabric Interconnect that connects to upstream switches via four 10-Gbps port channels. You have a fully populated Cisco UCS B-Series
Blade Server chassis that has a UCS-IOM-2208XP installed and uses all of the ports for the blade servers. What is the oversubscription ratio between the chassis and the upstream switch?

Answer options

Correct answer: B

Explanation

The correct oversubscription ratio is 3:1, which means for every 3 Gbps of bandwidth used by the blade servers, there is only 1 Gbps available to the upstream switch. The other options do not reflect the correct calculations based on the number of ports and their bandwidth, leading to incorrect oversubscription ratios.
