A customer reports that after installing DP4400, their backup performance is poor. You discover only 1GbE ports were used for data traffic.
What is the BEST recommendation to resolve this issue?
- A . Upgrade the RAID controller firmware
- B . Replace the disks with SSDs
- C . Connect and configure the 10GbE ports for data traffic
- D . Enable write-through caching
C
Explanation:

- A . The RAID controller is not configured
- B . The static IP was not properly assigned during deployment
- C . The Avamar OVA is corrupted
- D . The VMware Tools are outdated
B
