You are expanding the compute layer of a VDC, and need to add more access layer switches to
provide connectivity to the hypervisors. However, there are no available ports on the two
aggregation layer switches to accommodate the uplink connections from the new access layer
switches, and all uplinks are active and operating at 95% of capacity.
Your design must satisfy all of the following requirements:
– Expand the access layer
– Maintain the same configuration as the existing environment
– Maintain the performance of the existing environment
The CIO has authorized you to purchase additional aggregation layer switches if needed.
What should you recommend?

A.
Purchase two new aggregation layer switches.
Aggregate them into a virtual switch.
Connect the new access layer switches to them.

B.
Purchase one new aggregation layer switch.
Connect the new access layer switches to it.

C.
Purchase one new aggregation layer switch.
Aggregate it with the existing switches.
Redistribute all access layer switches across all aggregation layer switches.

D.
Purchase two new aggregation layer switches.
Connect the new access layer switches to them.
