Final answer:
The IEEE specification related to NIC teaming is C) IEEE 802.3ad, which is also known as IEEE 802.1AX, used for combining multiple Ethernet links into a single logical link.
Step-by-step explanation:
The IEEE specification that relates to NIC (Network Interface Card) teaming is C) IEEE 802.3ad. NIC teaming, also known as link aggregation or bonding, involves combining multiple network connections in parallel to increase throughput beyond what a single connection could sustain, or to provide redundancy in case one of the links should fail. The specification IEEE 802.3ad, now known as IEEE 802.1AX, provides the method for network devices to combine multiple Ethernet links into a single logical link for the purposes of bandwidth aggregation and/or redundancy.
The other options provided relate to different technologies:
- IEEE 802.1Q concerns VLAN tagging.
- IEEE 802.11ac is a wireless networking standard.
- IEEE 802.16e pertains to mobile WiMAX.
