Which of the following network device functions can reduce host CPU utilization?

A TCP Offload Engine (TOE) is a technology found in network interface cards that offloads the processing of the entire TCP/IP stack from the host CPU to specialized hardware on the NIC, thereby significantly reducing host CPU utilization for network traffic.

FCoTR (Fibre Channel over Token Ring) is not a recognized or common technology, and would not inherently reduce host CPU utilization for general network tasks.

Link aggregation combines multiple network links for increased bandwidth and redundancy but does not offload CPU-intensive protocol processing from the host.

Jumbo frames reduce the number of frames processed but do not offload the complex TCP/IP stack processing from the host CPU in the same direct way as a TOE.
