Exam CV0-003 topic 1 question 175 discussion

No description of the error. Could be compute. Could be license.

The error occurring during a vertical-scaling test of the vCPU on the VMs suggests that the issue is likely related to compute resources. Vertical scaling, also known as scaling up, involves increasing the capacity of an individual VM, which primarily involves adding more CPU and memory resources to the VM. **Answer: A. Compute** In a virtualized environment, compute resources such as CPU and memory are allocated to VMs. When you perform vertical scaling by adding more vCPUs to a VM, it requires that the underlying physical host has available CPU resources to allocate. If there are not enough available CPU resources on the host, you may encounter errors or limitations when trying to vertically scale the VMs.

If the administrator encounters an error during the vertical-scaling test, it suggests that there may be insufficient compute resources available in the three-server cluster to accommodate the increased vCPU allocation. This could be due to limitations in the underlying hardware, such as the number of physical CPU cores or the amount of available processing power.

Vertical scaling, also known as scaling up, is the process of adding resources such as processing power (CPU) or memory to a server. If the administrator is getting an error while trying to scale the vCPU on the VMs, it's likely that there's a compute resource limitation

gets an error ?? wow , I'm supposed to be a magician to know what is the error shit that caused by compute or license issue ...shitttttt on comptia

It could be a licensing issue if the Hypervisor is a per socket/core license. Vertically scaling the CPU may not work if there are no more valid CPU's left to use and the new ones can't be allocated.

If a systems administrator gets an error while executing a vertical-scaling test of the vCPU on VMs in a virtualized environment, the issue is MOST likely related to "Compute" (A). In a virtualized environment, the "Compute" refers to the processing power (CPU and RAM) of the physical host machine that runs multiple virtual machines. Vertical scaling is the process of adding more resources to a virtual machine to increase its processing power. If the administrator is encountering an error while executing a vertical-scaling test of the vCPU on VMs, it indicates that there may be an issue with the compute resources available to the VMs, such as insufficient processing power or limited capacity on the physical host.

A. Compute is the most likely issue occurring if the systems administrator is getting an error while executing a vertical-scaling test of the vCPU on the VMs in a three-server cluster with 12 VMs running on each server. Vertical scaling refers to increasing the resources of a single virtual machine, such as increasing the number of vCPUs. This requires additional resources from the physical host, specifically compute resources. If the compute resources of the physical host are already being fully utilized by the existing VMs, then there may not be enough resources available to support the additional vCPUs required by the newly scaled VMs. Storage and licensing issues are less likely to cause errors while executing a vertical-scaling test of the vCPU on the VMs. Scripts can cause issues, but they are unlikely to be the primary cause of an error related to vertical scaling of vCPUs.

Sounds like a per core licensing issue. Even if you added more vCPU's per VM than you had available, you'd just be over subscribed... and wouldn't get a error on start.

if the licensing is based on a per core situation and you add more vCPU's then you could run into licensing issues

A is correct.

What does licensing have to do with vertical scaling? I'd go with compute since that's what we're dealing with. Licensing is an issue with horizontal scaling.
