Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 162

Which two considerations must a network engineer have when planning for voice over wireless roaming? (Choose two.)

Answer options

• A. Full reauthentication introduces gaps in a voice conversation.
• B. Roaming time increases when using 802.1x + Cisco Centralized Key Management.
• C. Roaming occurs when the phone has seen at least four APs.
• D. Roaming occurs when the phone has reached גˆ’80 dBs or below.
• E. Roaming with only 802.1x authentication requires full reauthentication.

Correct answer: A, E

Explanation

Option A is correct because full reauthentication can disrupt voice calls, which is critical for maintaining call quality. Option E is also correct as it highlights that using only 802.1x requires complete reauthentication, which can further impact voice continuity. The other options either provide incorrect information or do not directly relate to the main considerations for voice over wireless roaming.
