What is the primary purpose of configuring port security on a switch?

• A. To increase bandwidth
• B. To limit unauthorized network access
• C. To enhance signal strength
• D. To enable VLAN segmentation

Answer: (B)

The primary purpose of configuring port security on a switch is to limit unauthorized network access. Port security helps protect the local area network (LAN) from potential threats by controlling which devices are allowed to connect to the network through switch ports. When port security is configured, the switch can recognize specific MAC addresses and can allow or block access based on predefined rules. This is critical for preventing unauthorized devices from joining the network, which could lead to various security issues such as data theft, network disruptions, or the introduction of malware. By enforcing port security policies, organizations can maintain control over who accesses their network resources and minimize the risk of attacks or breaches. In contrast, increasing bandwidth, enhancing signal strength, and enabling VLAN segmentation are not primary functions of port security. Bandwidth pertains to the amount of data that can be transmitted over the network, signal strength involves the quality of the connection, and VLAN segmentation deals with dividing a network into separate broadcast domains for efficient data management. These aspects are essential for network performance but are fundamentally different from the security measures defined by port security protocols.
