Cisco Certified Support Technician (CCST) NetworkingNetwork AccessHard
A network technician is configuring an access point (AP) in a new wireless network. The AP needs to support multiple wireless networks, each associated with a different VLAN, to segment traffic for guests, employees, and printers. Which configuration concept must be applied to the AP to achieve this segmentation?
- APower over Ethernet (PoE)
- BSSID-to-VLAN mapping
- CChannel bonding
- DMAC address filtering
Show answer & explanationAnswer & explanation
Correct answer: B. SSID-to-VLAN mapping
SSID-to-VLAN mapping allows an access point to broadcast multiple SSIDs, with each SSID being associated with a specific VLAN. This effectively segments wireless traffic, sending devices connected to one SSID to their designated VLAN, separate from other SSIDs and their VLANs.
Why the other options are wrong
- A. PoE provides power to the AP over the Ethernet cable but has no role in traffic segmentation or VLAN assignment.
- C. Channel bonding combines multiple adjacent wireless channels to increase bandwidth but is unrelated to traffic segmentation into VLANs.
- D. MAC address filtering controls which specific devices can connect to the wireless network but does not segment traffic into different VLANs.
SSID-to-VLAN Mapping
A wireless network configuration where multiple Service Set Identifiers (SSIDs) are broadcast from a single Access Point, with each SSID being associated with a distinct VLAN for traffic segmentation.
- Allows multiple virtual wireless networks
- Each SSID maps to a unique VLAN
- Provides traffic segmentation and isolation
- Requires the AP to be connected to a trunk port on the switch
Memory trick: Each SSID gets its own VLAN house.
