Final answer:
Windows Server 2008 R2 does support up to 64 physical processors, true to the provided statement. This support is available in specific versions such as the Datacenter and Itanium editions of the operating system.
Step-by-step explanation:
The statement that Windows Server 2008 R2 supports up to 64 physical processors is True. Windows Server 2008 R2, in its Datacenter and Itanium editions, indeed supports up to 64 physical processors. This capability is designed to provide high scalability for larger and more demanding enterprise environments. However, it's important to differentiate between physical and logical processors; Windows Server 2008 R2 can also support more logical processors (cores and hyper-threading) depending upon the edition and the system's hardware.
