By using link aggregation and stacking technology in a campus network, network reliability can be improved.

• BFALSE

Explanation

Link aggregation (LAG/LACP) bundles multiple physical links into a single logical link, providing both increased bandwidth and redundancy - if one link fails, traffic continues over the remaining links. Stacking technology connects multiple switches to operate as a single logical unit, eliminating single points of failure at the switch level and enabling seamless failover. Together, these technologies address two common failure domains (link failure and device failure), which is exactly what network reliability means in a campus context.

Why B is wrong: "FALSE" would only be correct if these technologies had no bearing on reliability - but redundancy is their primary design purpose alongside bandwidth aggregation. There is no valid counterargument here; this is a straightforward true/false on well-established networking principles.

Memory tip: Think "two cables are better than one, two switches are better than one" - LAG stacks the links, stacking stacks the switches. Both multiply your paths and eliminate single points of failure, which is the definition of improved reliability.
