Redundancy — CompTIA Network+ (N10-009) Practice Questions
Redundancy in networking refers to the practice of duplicating critical components or paths so that a failure in one element does not bring down the entire network. The N10-009 exam covers redundancy at multiple layers, including redundant uplinks, switch stacking, link aggregation (LACP), redundant power supplies, and dual WAN connections. Candidates are expected to understand how protocols such as Spanning Tree Protocol prevent loops while still enabling redundant switch paths. Questions on redundancy often appear alongside high-availability and disaster-recovery scenarios, requiring candidates to select the most appropriate design for a given business requirement.
