VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 26

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.)

Answer options

• 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

Correct answer: A, D

Explanation

The correct answers, A and D, are essential to ensure that backup traffic is properly prioritized and managed without affecting existing services. Enabling and tagging the backup traffic allows for its separation, while matching CoS and DSCP values ensures that the backup traffic is treated appropriately by the network. Options B, C, and E do not address the requirement of preventing impact on current services effectively.
