What result might occur if a network administrator does not configure firewall settings properly?

When firewall settings are not configured properly, one of the primary outcomes is likely to be network accessibility issues. Firewalls are designed to control the flow of incoming and outgoing network traffic based on predetermined security rules. If these settings are incorrect, legitimate traffic might be blocked, preventing users from accessing necessary resources or services on the network. This could lead to both user frustration and disruptions in business operations.

On the other hand, while improper configuration might seem like it could enhance security or improve network speed, it often leads to the opposite effect. Firewall misconfigurations can leave vulnerabilities open, potentially compromising security. Hence, the correct configuration is crucial to ensure smooth accessibility and optimal security for the network.
