NIC counts can vary based on VM tasks.

• A. The number of NICs is fixed
• B. NIC counts can vary based on VM tasks
• C. NICs are not used in virtualized environments
• D. NICs are determined by the host's CPU speed

Answer: (B)

In virtualization, the number of network adapters you assign to a virtual machine is flexible and driven by what the VM is doing. A VM can have multiple virtual NICs to handle different networks, separate traffic types (like management vs. data traffic), or to connect to separate VLANs. As the workload changes, you can add or remove these virtual adapters, so NIC counts can vary based on VM tasks. The host machine may have a fixed set of physical NICs, but the VM’s virtual NICs are a separate, configurable resource that the hypervisor exposes to meet the VM’s networking needs. Some platforms even allow hot-adding NICs while the VM is running, further enhancing this flexibility. The other statements don’t fit virtualization realities: the number of NICs isn’t fixed for a VM, NICs are indeed used in virtualized environments, and the host’s CPU speed doesn’t determine how many NICs a VM can have (it affects performance, not count).
