Wireless Deployment
Question
An engineer has deployed a WLAN in a high-density auditorium and expects the number of clients to grow. Which WLC configuration can be used increase the IP space without any service disruptions?
Exhibit
Options
- ARF group
- Binterface group
- Cdynamic interface
- DAP group
Explanation
Interface groups pool multiple dynamic interfaces under a single WLAN so additional subnets can be added to expand IP space without modifying or disrupting the existing WLAN service.
Common mistakes.
- A. RF groups manage radio resource coordination between WLCs and have no effect on DHCP scope size or the number of available IP addresses.
- C. A single dynamic interface is bound to one VLAN and one DHCP scope; replacing or resizing it requires reconfiguring the WLAN, which causes a service disruption.
- D. AP groups determine which WLANs are advertised by which APs and do not influence DHCP pool capacity or IP address availability.
