Question
During initial testing of a new VD' deployment, users are complaining that they are not seeing the performance increase that was seen during the POC phase of the project. The POC deployment was tested on an NX line of nodes with AHV as the hypervisor. After the test, the customer has decided to move forward with a production deployment using Dell XC nodes with ESXi as the hypervisor. Which two actions must be taken. based on the hypervisor and node model change? (Choose two.)
Options
- ADisable the C-states.
- BConfigure Video Drivers
- CChange power Management
- DUpdate Network Drivers

Explanation
Moving from AHV on NX nodes to ESXi on Dell XC nodes introduces two specific performance considerations. First, C-states (A) are CPU power-saving states that allow processor cores to enter deep sleep. On ESXi-based VDI, C-states can cause significant CPU wake-up latency, leading to inconsistent response times and perceived performance degradation. Disabling C-states in the BIOS is a documented best practice for ESXi VDI deployments. Second, updating Network Drivers (D) is required because the Dell XC platform uses different network hardware than the NX nodes used in the POC. Incorrect or outdated network drivers on ESXi can cause throughput issues and latency, directly impacting VDI protocol performance. Changing power management (C) is related to C-states but is broader and less precise; disabling C-states is the specific action required.
