Exam N10-008 topic 1 question 355 discussion

A. Data link When a user moves from a wireless to a wired connection, new protocols are activated at the Data Link layer of the OSI model. This layer is where Ethernet protocols for wired connections and 802.11 protocols for wireless connections operate. The Data Link layer is responsible for node-to-node data transfer and detecting errors that may occur in the Physical layer below it. Switching from wireless to wired or vice versa involves changing the way data packets are framed and addressed at this layer.

I would think the Network layer. 802.3 and 802.11 are protocols in the network layer for Ethernet and wireless respectively. When switching from 802.11 to 802.3, a new protocol is activated.

The layer of the OSI model that is primarily responsible for handling changes in the network configuration, such as a user moving from a wireless to a wired connection, is the Network layer (Layer 3). Therefore, the correct answer is: B. Network

Should be data link. It is a bad question neverthless

A. Data link The data link layer of the OSI model is responsible for transmitting data over a physical connection, and is responsible for managing the physical connection between network devices. When a user moves from a wireless to a wired connection, the physical connection changes and new protocols need to be activated in order to manage the new physical connection. Therefore, it is the data link layer that has new protocols activated when a user moves from a wireless to a wired connection.

Mike Meyers "The Data Link layer also determines how data is placed on the wire by using an access method. The wired access method, carrier-sense multiple access with collision detection (CSMA/CD), was once used by all wired Ethernet networks, but is automatically disabled on switched full-duplex links, which have been the norm for decades. Carrier-sense multiple access with collision avoidance (CSMA/CA) is used by wireless networks, in a similar fashion."
