Sample answer
“At my internship with a local IT firm, we experienced frequent dropped calls on our Cisco VoIP system. I first checked the call logs using Cisco Unified Communications Manager and identified a pattern with specific extensions. I then used Wireshark to analyze the network traffic, which revealed packet loss due to bandwidth congestion. I collaborated with the network team to implement QoS policies, resulting in a 40% reduction in call drops and improved user satisfaction.”
