Which three options are three of the main advantages of the Cisco Unified Access WLAN architecture over the Autonomous access WLAN? (Choose three.)

Question

Options

• Aability to send only one type of traffic at a time
• Bincreased reliability with failover and self-healing mechanisms
• Cfaster creation of wireless "islands" for every application in the plant
• Dincreased deployment, management, and integration costs
• Eenhanced security services with centralized control and visibility
• Fcan be used for roaming within the plant

• A
  11% (4)
• B
  81% (29)
• C
  3% (1)
• D
  6% (2)

Explanation

Cisco's Unified (controller-based) WLAN centralizes intelligence in a Wireless LAN Controller (WLC), which is the key to understanding why B, E, and F are correct. The WLC coordinates all APs, so it can automatically compensate when an AP fails by adjusting neighboring APs - enabling the failover and self-healing described in B. Centralized control also means security policies are configured once and enforced consistently across every AP, providing the enhanced visibility and centralized security in E. Finally, because the WLC tracks client associations globally, it can hand off a client between APs without re-authentication, enabling seamless roaming (F) - something autonomous APs cannot do since each is an independent "island."

Why the distractors are wrong:

• A - Sending "only one type of traffic at a time" is a limitation, not an advantage; both architectures support multiple traffic types.
• C - Wireless "islands" are actually the problem with autonomous WLAN (each AP manages itself independently); unified architecture eliminates islands.
• D - Higher costs are a disadvantage; unified architecture actually reduces ongoing management costs through centralization.

Memory tip: Think "BEF = Better, Enhanced, Free-roam" - the WLC makes the network Better at surviving failures, Enhanced in security, and gives clients Free seamless roaming. Anything describing a cost increase or a limitation belongs to the autonomous model, not unified.
