A user complains of slow internet speeds. How would you troubleshoot this issue, and what steps would you take to improve the network performance?

The correct option is "Check bandwidth usage." Slow internet speeds can be caused by various factors, including high bandwidth usage. To troubleshoot, you can use network monitoring tools to identify bandwidth-intensive applications or devices consuming excessive bandwidth. Once identified, you can take steps to optimize bandwidth usage, such as limiting access to non-essential applications or upgrading the internet connection if necessary.
