CV0-003 Question #84: Real Exam Question with Answer & Explanation
The correct answer is A: increase the VMs vRAM.. When a VM needs to perform at higher levels, the administrator should scale its virtual compute resources - specifically virtual RAM and virtual CPU count - to meet increased workload demands.

Question
When a customer requests a VM to perform at higher levels the administrator should (Select two):
Options
- Aincrease the VMs vRAM.
- Bincrease RAM on the host.
- Cmigrate the VM to a faster online host.
- Dincrease the VMs vCPU count.
- Eincrease disk space.
Explanation
When a VM needs to perform at higher levels, the administrator should scale its virtual compute resources - specifically virtual RAM and virtual CPU count - to meet increased workload demands.
Common mistakes.
- B. Increasing RAM on the host improves the host's overall capacity but does not directly allocate more resources to the specific VM that needs higher performance.
- C. Migrating to a faster host may help if the current host is the bottleneck, but it is disruptive and not the first corrective action; tuning the VM's own resource allocation is preferred.
- E. Increasing disk space addresses storage capacity constraints, not compute performance, and would not improve a VM's processing speed or responsiveness.
