Question 1 of 30
A network engineer is troubleshooting a connectivity issue in a corporate environment where users are unable to access a critical application hosted on a remote server. The engineer discovers that the application server is reachable via ping, but users are experiencing timeouts when trying to establish a TCP connection on port 80. The engineer checks the firewall settings and finds that the rules allow traffic on port 80. However, upon further inspection, the engineer notices that the server\'s CPU utilization is consistently above 90%. What is the most likely cause of the connectivity issue?
The application server is overloaded and unable to handle incoming requests.
The firewall is misconfigured to block TCP connections intermittently.
There is a DNS resolution issue preventing users from connecting to the server.
The network switch is experiencing high latency affecting TCP connections.
