Question

Which statement best describes protocol filtering that has been implemented in a wireless bridge? 1. Allowing or denying wireless traffic using Open Systems 2. Interconnection (OSI) reference model Layer 4 ports to filter Layer 7 applications.

Answer 1

Protocol filtering in a wireless bridge involves managing traffic by examining OSI model layers, specifically using Layer 4 ports to control Layer 7 applications.

Step-by-step explanation:

Protocol filtering implemented in a wireless bridge involves the management of network traffic based on specific protocols used in communication. This can involve allowing or denying wireless traffic based on predefined rules that refer to various layers of the Open Systems Interconnection (OSI) model. In the context of the statement, it implies that the wireless bridge may use filtering rules set up at the Layer 4 (Transport Layer) to control traffic associated with Layer 7 (Application Layer) protocols or applications. This means the bridge could allow or block traffic related to specific applications by inspecting the destination or source ports associated with those applications.
