Which of the following components is not required to provide necessary computing, storage, and network resources for VMs during VM creation?

In an OpenStack environment, VM creation requires core services for compute, network, and storage. Nova is the compute service that manages the VM lifecycle. Neutron provides the networking services, creating virtual networks and ports for the VM. Cinder offers persistent block storage (volumes) for the VM. Ceilometer, however, is the telemetry service. Its role is to collect metrics and event data on resource usage for monitoring, billing, and alerting. It does not provide the fundamental resources needed for a VM to be created and run.

A. Nova is the essential OpenStack compute service responsible for provisioning and managing the lifecycle of virtual machines.
B. Neutron is the core networking service, mandatory for providing network connectivity and IP addresses to the VM.
D. Cinder is the block storage service that provides persistent storage volumes, a key resource type for many VMs.
