Exam 300-430 topic 1 question 251 discussion

To meet the requirement of locally switching client traffic for a new SSID mapped to an onsite voice VLAN (VLAN 25), the switch interface connecting to the APs must be configured as a trunk port. This allows the AP to handle multiple VLANs, including the voice VLAN, for locally switched traffic. switchport mode trunk: Configures the port as a trunk port, enabling the AP to carry traffic for multiple VLANs. switchport trunk allowed vlan add vlan 25: Ensures that VLAN 25 (the voice VLAN) is allowed on the trunk port, allowing the AP to map the SSID to this VLAN. This configuration is necessary because: The AP needs to support both the existing centrally switched traffic and the new locally switched traffic for the voice SSID. The trunk port allows the AP to tag traffic with the appropriate VLAN IDs, including VLAN 25 for voice devices.
