A mission critical server has faulted with a dead 66 MHz 3.3V PCI-X network interface card. The system
administrator has been directed to get the server functional as soon as possible, even if it is connected with
less bandwidth. There are no onsite spare cards available and the vendor does not expect to have the parts for
at least a week. Which of the following immediately available NICs could be substituted instead?

A.
33 MHz 3.3V PCI

B.
66 MHz 5V PCI

C.
266 MHzx 3.3V PCI-X

D.
533 MHz 5V PCI-X
