What is a major advantage of configuring port security on servers?

• A. It allows all devices full network access
• B. It can restrict access to specific devices
• C. It increases database performance
• D. It simplifies user access controls

Answer: (B)

Configuring port security on servers offers a significant advantage by allowing access to be restricted to specific devices. This is particularly important in secure environments where controlling who and what can connect to the network is paramount. By enabling port security, administrators can specify which devices—identified by their MAC addresses—are permitted to communicate over the network. This helps prevent unauthorized access and mitigates risks associated with rogue devices connecting to the network, enhancing overall security.

The other options do not align with the primary function of port security. Allowing all devices full network access undermines the very purpose of port security, which is to create barriers against unauthorized access. While port security may have an indirect effect on database performance by reducing unauthorized traffic, its primary role is not performance enhancement. Lastly, while port security can aid in limiting access to known entities, it does not simplify user access controls in a manner that is the primary focus of its configuration; rather, it enforces strict controls based on device identity.
