Which of the following is used to limit the amount of bandwidth used on a link for different applications to improve overall performance?
The correct answer is D. Traffic shaping. Traffic shaping is a bandwidth management technique that controls and limits the rate of traffic for specific applications on a link. QoS is a broader concept focused on prioritization, not rate limiting.

Why each option
Traffic shaping is a bandwidth management technique that controls and limits the rate of traffic for specific applications on a link. QoS is a broader concept focused on prioritization, not rate limiting.
QoS classifies and prioritizes traffic types but does not inherently limit or cap bandwidth consumption for specific applications on a single link.
Fault tolerance is a design strategy for maintaining operation after component failures, and is unrelated to bandwidth management.
Load balancing distributes traffic across multiple links or servers to prevent overload, but does not limit per-application bandwidth on a single link.
Traffic shaping actively delays or queues packets to conform to a configured rate, directly capping how much bandwidth specific applications can consume on a link. This prevents any single application from monopolizing the link and improves performance for all traffic types.
