Question 1

A data center is experiencing performance issues due to resource contention among virtual machines (VMs). The administrator decides to implement a resource allocation strategy that prioritizes critical applications while ensuring that less critical workloads do not starve. If the total available CPU resources in the cluster are 100 GHz and the critical applications require a minimum of 60 GHz to function optimally, how should the administrator allocate the remaining resources to ensure that all VMs receive adequate CPU time without exceeding the total capacity? Assume that there are three less critical VMs, each requiring 10 GHz, and one additional VM that can dynamically adjust its CPU needs between 5 GHz and 15 GHz based on workload.

Accepted Answer

Allocate 60 GHz to critical applications, 30 GHz to the three less critical VMs (10 GHz each), and allow the dynamic VM to use the remaining 10 GHz as needed.

Question 2
