Question
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.)
Options
- AEnable and tag traffic on the backup distributed port group
- BAdd a new two-port 10 GbE NIC per ESXi host
- CReplace the existing NIC with a two-port 25 GbE NIC per ESXi host
- DMatch the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the
- ECreate a new virtual switch using the 1 GbE uplinks

Explanation
Assign priority tags to traffic, such as VoIP and streaming video, that has higher networking requirements for bandwidth, low latency, and so on. You can mark the traffic with a CoS tag in Layer 2 of the network protocol stack or with a DSCP tag in Layer 3. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID- 84207BEA-986E-443E-94B0-B1EC66C56598.html
