Which should the architect recommend to improve vSphere VM throughput?

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution and resolving a network throughput bottleneck.

This information was gathered during a workshop:

– A VM running a business critical application Is peaking at ~5Gbps

– Current host uplink is configured as Active/Standby with two 10Gb NICs.

– The installed server NIC model does not support GENEVE offload.

– All VM traffic is East/West.

– The business critical application VM communicates with multiple client VMs.

Which should the architect recommend to improve vSphere VM throughput?
A . Configure the Transport Node Uplink Profile to use a Load Balance Source teaming policy with two active uplinks.
B . Deploy an additional Edge Node to the Edge Node Cluster.
C . Replace the existing network switches and routers with newer higher-performance.
D . Replace the existing NICs with a model that supports GENEVE offload.

Answer: D

Explanation:

Z C(D) will perform the necessary offload to greatly improve performance. The 5GBps isn’t saturating the actual pNIC, and while switching the uplink to active/active will help some, the issue will come back during a pNIC failure.
