Hi guys,
I am coursing a VxRail training and I have doubts with this question.
A virtual distributed switch is configured with a default vSAN port group containing one active and one standby uplink. What is the process to configure vSAN traffic to be active on two uplinks?
What do you think is the correct one?. I think that it's the C option.
Many thanks in advance.
Is this from a VMware exam?
While IMO none of these option fully explains how this can be done, I recommend that you read https://docs.vmware.com/en/VMware-vSphere/7.0/vsan-703-network-design-guide.pdf which explains the different options.

@mdiazrivera Bit late response but the answer is D e.g. change the uplinks from Active/Standby to Active/Active - note (and out of scope for this exam I assume), in real-life this would likely require additional switch-side configurations in order to work properly.
Hey @TheBobkin , I have just noticed a discrepancy in VSAN documentation.
In the vSAN Network Design PDF, you can read this in page 32
"Route Based on Originating Virtual Port
In Active/Active or Active/Passive configurations, use Route based on originating virtual port for
basic NIC teaming"
https://docs.vmware.com/en/VMware-vSphere/7.0/vsan-703-network-design-guide.pdf
In Designing VSAN Network there is this
So one document says to use both Active/Passive and Active/Active (with Route Based on Originating Virtual Port) and the second one only Active/Passive.
From my experience, Active/Passive is much better (if you are NOT using LAG), because you avoid to jump from one switch to another one (usually on Active/Acitve the 2 uplinks are on different switches) and this could end in a tremendous performance impact (also this came from field experience with Aruba switches, that I will NEVER EVER suggest for VSAN).
Also using the Load Balancing based on network load will have the same problem, so it's better to avoid until you are absolutely sure that your switches uplinks are oversized.
