Exam SK0-005 topic 1 question 177 discussion

The correct answer is: ✅ A. Committing more virtual resources to virtual machines than there are physical resources present Explanation: Overprovisioning refers to the practice of allocating more virtual resources (such as CPU, RAM, or storage) to virtual machines (VMs) than the physical host actually has available. In a virtualized environment, hypervisors can sometimes allow VMs to be allocated more resources than are physically available, with the assumption that not all VMs will require their full allocation at the same time. However, if too many VMs demand their full resources simultaneously, it can lead to performance issues or even failures. This practice can work if the overall load is well managed, but it can be risky if resource contention becomes an issue.

It's (B). Per the CompTIA Server+ Student Guide: Overprovision Systems administrators must ensure that the host server has enough physical hardware resources to meet the needs of the VMs. Therefore, the server is equipped with more hardware resources than the anticipated use requires.

The BEST description of overprovisioning in a virtual server environment is: A. Committing more virtual resources to virtual machines than there are physical resources present This accurately describes the concept of overprovisioning in virtualization. Overprovisioning refers to allocating more resources to virtual machines collectively than the physical host actually has available

I chose A, because B won't lead to an actual issue with the virtual servers. Using a hard drive as an analogy, if I have 1 TB of data to store and a 2TB drive, I will be fine. If I have 1 TB of data to store, but only a 500 GB drive, I will be over capacity. Over provisioning then in this case, means you have more virtual servers than the physical hardware can support. Or to go back to our analogy, you only have 500GB of capacity, but you are trying to store 1TB of data. That said, the question is poorly worded.

poorly worded. if you're overprovisioning the VMs it is A, if you're overprovisioning the host it is B

To provide more than is necessary.

overprovisioning = To provide more than is necessary.

Correct Answer: B Systems administrators must ensure that the host server has enough physical hardware resources to meet the needs of the VMs. Therefore, the server is equipped with more hardware resources than the anticipated use requires.

Which of the following BEST describes overprovisioning in a virtual server environment? A. Committing more virtual resources to virtual machines than there are physical resources present B. Installing more physical hardware than is necessary to run the virtual environment to allow for future expansion C. Allowing a virtual machine to utilize more resources than are allocated to it based on the server load D. Ensuring there are enough physical resources to sustain the complete virtual environment in the event of a host failure
