A is correct

A for sure

A is the correct answer. Consider the following when preparing a vSAN network: • For best networking performance, all hosts must be connected in the same subnet. In vSAN 6.0 and later, you can also connect hosts in the same layer 3 network if necessary. • Dedicate network bandwidth on a physical adapter and allocate at least 1 Gbps of bandwidth for vSAN. You might use one of the following configuration options: - Dedicate 1-GbE physical adapters for a hybrid host configuration. - Use dedicated or shared 10-GbE physical adapters for all-flash configurations. - Use dedicated or shared 10-GbE physical adapters for hybrid configurations if possible. - Direct vSAN traffic on a 10-GbE physical adapter that handles other system traffic and use Network I/O Control on a distributed switch to reserve bandwidth for vSAN. • Configure a port group on a virtual switch for vSAN: - Assign the physical adapter for vSAN to the port group as an active uplink. - You can also assign vSAN traffic to a VLAN by enabling tagging in the virtual switch.

yes, ruling out, we must create a dedicated workgroup for vsan and use NIOC in case there is contention on the network. Using jumbo frames can be another option but sharing vsan traffic in a workgroup together with other types it's a no-no
