CISSP Question of the Week: OSI Layer for Formatting Data

The correct answer is D.

The Presentation layer, or layer 6, is normally a part of the operating system. Its main responsibilities include formatting data, encrypting data and translating packets it receives. This layer translates between application and network data formats. The Presentation layer works to transform data into the form that the Application layer can accept. It formats and encrypts data to be sent across a network, providing freedom from compatibility problems. An example of a protocol that operates at this layer is the MIDI digital music protocol.

Both the Presentation and Session layers provide TCP/IP end-to-end security.
