Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 79

When using multiple SSIDs on a lightweight AP, how does the traffic of each SSID reach the 802.3 network?

Answer options

• A. provide routing between them at the core so that the SSIDs can reach the internet
• B. configure 802.11q trunking on the Ethernet switch port that is connected to the AP
• C. configure ACLs at the switch port that will allow all desired SSIDs to pass traffic
• D. configure the SSIDs on the WLC and it will regulate the traffic based on traffic type

Correct answer: B

Explanation

The correct answer is B because 802.11q trunking allows multiple VLANs to be carried over a single Ethernet link, which is necessary for routing traffic from different SSIDs. Option A is incorrect as routing alone does not handle traffic segregation; option C is not sufficient since ACLs do not enable VLAN tagging; and option D misunderstands the role of the WLC, which manages SSID configurations but does not directly regulate traffic types without trunking.
