In the context of the OSI model, the network layer is responsible for packet forwarding including routing through intermediate routers. Hence, the network layer PDU is known as a packet.

In the context of Aruba networks, a Microbranch environment is managed using a group persona that aligns with the functionality required. ArubaOS 10 Branch Gateway Group Persona would be the correct device type and group persona for managing a Microbranch environment, as it would provide the necessary features and controls for branch networking requirements.

In a 2.4GHz WLAN environment, channels 1, 6, and 11 are recommended for use simultaneously to avoid co-channel interference because these channels do not overlap with each other. Each of these channels is separated by enough frequency space to ensure that the signals do not interfere, which is not the case with other channel combinations.

When a client roams from one access point to another, it must change the destination MAC address on its 802.11 frames to match the new access point to which it is associated. The SSID does not change since it is typically consistent across an entire WLAN, and the default gateway remains the same as long as the client stays within the same IP subnet. The association to a new access point involves updating the destination MAC address in the frames that the client sends.

The VoIP phones will mark their traffic with a local-priority value, which, if the QoS trust mode is none, will correspond to CoS map entry 1 by default. The local-priority value of 1 at the branch office likely indicates that the traffic is not being prioritized correctly compared to the corporate office, where a local-priority of 5 suggests a higher level of prioritization for voice traffic.
