Answer: C
Redundancy, by building some form of duplication into the
network components, such as a link, a router, a switch to
prevent loss, delays, or data duplication is a control over
component communication failure or error. Other related
controls are loop/echo checks to detect line errors, parity
checks, error correction codes and sequence checks. Choices
A, B and D are communication network controls.
