Cloud Architecture and Design
Question
Which of the following is the BEST way to achieve network throughput on any host with existing NICs?
Options
- A802.3ad
- B802.3x
- C802.11n
- D802.11i
Explanation
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.
Common mistakes.
- A. 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.
- B. 802.3x defines Ethernet flow control via pause frames to manage congestion and reduce packet loss, which does not increase maximum network throughput.
- D. 802.11i defines the security framework for Wi-Fi networks including WPA2 authentication and AES encryption, addressing security rather than throughput performance.
