Which two recommendations should the architect make to help the customer incorporate the service?

A Cloud Service Provider wants to introduce backup as a service for a customer’s vSphere-based virtual machines.

The following information is noted:

✑ They have a single four-port (2 × 10 GbE and 2 × 1 GbE) NIC per ESXi host

✑ All top-of-rack (ToR) switches are 10 GbE and fully populated

✑ The backup traffic must not impact existing services

Which two recommendations should the architect make to help the customer incorporate the service? (Choose two.)
A . Enable and tag traffic on the backup distributed port group
B . Add a new two-port 10 GbE NIC per ESXi host
C . Replace the existing NIC with a two-port 25 GbE NIC per ESXi host
D . Match the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the physical network
E . Create a new virtual switch using the 1 GbE uplinks
