350-401 Question #975: Real Exam Question with Answer & Explanation

Question

A customer requires their wireless network to be fully functional, even if the wireless controller fails. Which wireless design supports these requirements?

Options

• AFlexConnect
• Bmesh
• Ccentralized
• Dembedded

Explanation

FlexConnect (formerly known as Hybrid Remote Edge Access Point or H-REAP) is the correct answer because it allows access points to locally switch traffic and maintain wireless operations even when the connection to the wireless LAN controller (WLC) is lost - this is its defining feature, often called "standalone mode." In a centralized design (Option C), all traffic is tunneled back to the WLC, so if the controller fails, the entire wireless network goes down, which is the opposite of what the customer needs. A mesh network (Option B) focuses on extending wireless coverage across large areas using backhaul links between APs, but it doesn't specifically address controller failure survivability. An embedded design (Option D) places the controller function within a switch or AP, but this doesn't inherently guarantee network continuity if that embedded controller fails.

Memory Tip: Think of FlexConnect = Flexible + Independent - the APs are flexible enough to work independently of the controller when needed. If you see keywords like "controller fails," "branch office survivability," or "local switching," FlexConnect is almost always the answer.
