Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 148

Which two network problems indicate a need to implement QoS in a campus network? (Choose two.)

Answer options

• A. port flapping
• B. excess jitter
• C. misrouted network packets
• D. duplicate IP addresses
• E. bandwidth-related packet loss

Correct answer: B, E

Explanation

Excess jitter and bandwidth-related packet loss are clear indicators of network performance issues that QoS can help mitigate by prioritizing critical traffic. Port flapping, misrouted packets, and duplicate IP addresses are more related to network configuration problems rather than issues that QoS specifically addresses.
