Study Notes
- APIPA addresses are link local addresses, limiting communication to devices on the same network
- Error messages like "Limited or no connectivity" and "No internet access" may appear when using these addresses
- Voiceover IP and media streaming require low latency and high-speed networks for real-time communication
- Jitter is a network statistic measuring consistency in frame intervals for good voice call quality
- A high-speed network and low latency are essential for transferring large amounts of information quickly
- Bandwidth availability must be considered to prevent poor latency and network congestion
- Outdated equipment may not meet the high speeds and low latency required for some networks
- Packet captures provide detailed information about network issues, including latency and frame intervals
- Port flapping can indicate physical issues between devices, requiring testing of the cable and hardware.

Description
This quiz covers troubleshooting a scenario where there is no connectivity to a remote device on the network. It involves starting from the local device and working through the network to identify and resolve any connectivity issues. One of the initial steps is checking for network connectivity and ensuring the presence of a link light associated with the ethernet interface.
