Which two network problems Indicate a need to implement QoS in a campus network? (Choose two.)
A . port flapping
B . excess jitter
C . misrouted network packets
D . duplicate IP addresses
E . bandwidth-related packet loss

View Answer

Answer: B, E

Explanation:

Quality of Service (QoS) is essential in a campus network to manage packet loss and delay, which can significantly affect the performance of real-time applications. Excess jitter (B) refers to the variation in time between packets arriving, caused by network congestion, timing drift, or route changes.

Bandwidth-related packet loss (E) occurs when the network is unable to handle the volume of traffic, leading to dropped packets. Implementing QoS allows for prioritization of critical traffic and can mitigate these issues by managing traffic flows and ensuring that high-priority traffic is delivered efficiently, even in times of congestion.
