Which statement best describes the purpose of redundancy in Navy IT environments using HSRP/VRRP, NIC teaming, and load balancing?

• A. HSRP/VRRP monitor temperatures in data centers.
• B. NIC teaming reduces bandwidth.
• C. Redundancy prevents single points of failure by providing alternate paths.
• D. Load balancing reduces security rather than distributing traffic.

Answer: (C)

Redundancy is about keeping services available even if part of the system fails, by providing alternate paths and devices. In Navy IT environments this means having backup mechanisms so a single failure doesn’t cut off connectivity or capabilities. HSRP/VRRP create gateway redundancy by designating a primary router and a backup; if the primary router fails, the backup seamlessly takes over, preserving reachability. NIC teaming combines multiple NICs into a single logical link, giving you path redundancy (and in some modes extra bandwidth); if one NIC or its link goes down, traffic keeps flowing through the others. Load balancing distributes traffic across multiple servers or links to improve performance and prevent any single resource from becoming a bottleneck, contributing to availability but not primarily creating alternate paths. Taken together, redundancy that prevents single points of failure by providing alternate paths is the best description.
