CV0-003 · Question #222
Which of the following is the BEST way to achieve network throughput on any host with existing NICs?
The correct answer is C. 802.11n. IEEE 802.11n improves wireless network throughput on existing hosts by introducing MIMO technology and channel bonding without requiring additional hardware or switch-side changes.

Why each option
IEEE 802.11n improves wireless network throughput on existing hosts by introducing MIMO technology and channel bonding without requiring additional hardware or switch-side changes.
802.3ad (Link Aggregation Control Protocol - LACP) bonds multiple wired Ethernet ports to aggregate throughput, but it requires more than one physical NIC per host and a compatible managed switch configured for LACP, making it unsuitable for any single existing NIC.
802.3x defines Ethernet flow control via pause frames to manage congestion and reduce packet loss, which does not increase maximum network throughput.
802.11n introduced MIMO (Multiple-Input Multiple-Output) antenna technology and 40 MHz channel bonding, enabling theoretical throughput up to 600 Mbps compared to 54 Mbps with 802.11g. On any host already equipped with 802.11n-capable wireless NICs, enabling this standard delivers significantly improved throughput using existing hardware.
802.11i defines the security framework for Wi-Fi networks including WPA2 authentication and AES encryption, addressing security rather than throughput performance.
