Which of the following will BEST achieve this goal?

A systems administrator wants the VMs on the hypervisor to share CPU resources on the same core when feasible.

Which of the following will BEST achieve this goal?
A . Configure CPU passthrough
B . Oversubscribe CPU resources
C . Switch from a Type 1 to a Type 2 hypervisor
D . Increase instructions per cycle
E . Enable simultaneous multithreading

View Answer

Answer: E

Explanation:

Simultaneous multithreading (SMT) is a type of CPU technology that allows multiple threads to run concurrently on a single CPU core. Enabling SMT can help achieve the goal of having the VMs on the hypervisor share CPU resources on the same core when feasible, as it can increase the CPU utilization and efficiency by executing more instructions per cycle and reducing idle time or wasted cycles. Enabling SMT can also improve performance and throughput, as it can speed up processing and handle increased workload or demand.
