300-365 Question #127: Real Exam Question with Answer & Explanation
The correct answer is C: Add an interface and an interface group and change the existing SSID to map to it. When a VLAN is exhausting IP addresses and the subnet cannot change, Cisco WLC interface groups allow multiple interfaces to be pooled together under a single SSID to expand address capacity.
Wireless Deployment
Question
A customer's wireless network VLAN is rapidly exhausting IP addresses. The customer insists that the network range should not change, but he wants to address growing network needs. Due to poor network, design no additional network range surrounds the existing VLAN. Which action fullfith this requirement ?
Options
- ACreate an SSID with a different name mapped to existing network range.
- BCreate an SSID with the same name mapped to a larger interface
- CAdd an interface and an interface group and change the existing SSID to map to it
- DAdd an expanded interface and change the existing SSID to map to it
Explanation
When a VLAN is exhausting IP addresses and the subnet cannot change, Cisco WLC interface groups allow multiple interfaces to be pooled together under a single SSID to expand address capacity.
Common mistakes.
- A. Creating a new SSID with a different name mapped to the same existing interface does not add any additional IP addresses and does not resolve the exhaustion problem.
- B. Mapping the SSID to a larger interface implies assigning a different, larger subnet, which directly contradicts the requirement that the network range must not change.
- D. Adding an expanded interface and remapping the SSID would replace the existing subnet with a new one, violating the constraint that the network range must remain unchanged.
