The correct answer is A. Dynamic CPU. To ensure proper CPU resources for ten guest servers on a host with two quad-core processors, the administrator should implement Dynamic CPU, which allows for CPU oversubscription and flexible resource allocation based on demand, especially for off-hours use servers.
Question
An administrator has recently added a new host server to a private cloud environment. The host has two quad-core processors and 128GB of RAM. The server will have ten guest servers that require a minimum of 1 CPU and 8GB of RAM per server. Four of the servers will only be used during off hours. Which of the following should the administrator implement to ensure that the guest servers have the proper resources?
Options
- ADynamic CPU
- BRedundancy
- CNIC Teaming
- DDynamic RAM

Why each option
To ensure proper CPU resources for ten guest servers on a host with two quad-core processors, the administrator should implement Dynamic CPU, which allows for CPU oversubscription and flexible resource allocation based on demand, especially for off-hours use servers.
Dynamic CPU allocation enables the hypervisor to provision more virtual CPUs than physical cores, dynamically adjusting CPU resources among guest servers based on their current workload and priority, which is ideal for an oversubscribed environment where some servers are used off-hours. This technique allows efficient use of physical resources by sharing them among multiple virtual machines, preventing resource contention for CPU.
Redundancy involves duplicating components or systems to prevent service interruption, not to manage CPU resource allocation for oversubscribed virtual machines.
NIC Teaming combines multiple network interface cards for increased bandwidth or fault tolerance, and it does not manage CPU resources for virtual machines.
Dynamic RAM, while similar in concept, manages memory allocation, not CPU resources, and the question specifically highlights CPU oversubscription challenges with guest servers.
