The QoS queuing method that transmits packets out of the interface in the order the packets arrive is First In, First Out (FIFO). This method ensures that packets are sent in the exact same order they were received, without any prioritization or reordering. References := Study CCNA: Quality of Service (QoS) Queues and Queuing Explained3.

The fabric control plane node in a Cisco SD-Access deployment plays a critical role in the fabric’s operation. It contains a database that is essential for identifying an endpoint’s location within the network. This database is central to the fabric’s functionality, as it allows for the tracking of endpoints and networks. An overloaded control plane node that responds slowly can lead to application traffic loss on initial packets, which highlights the importance of this node in maintaining efficient network operations.

MAB (MAC Authentication Bypass) provides network access control based on the physical address (MAC address) of a device. It is an access control technique that enables port-based access control using the MAC address of the endpoint, typically used as a fallback mechanism to 802.1x89101112.
