Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 276

An engineer is following the proper upgrade path to upgrade a Cisco AireOS WLC from version 7.3 to 8.9. Which two ACLs for Cisco CWA must be configured when upgrading from the specified codes? (Choose two.)

Answer options

• A. Permit 0.0.0.0 0.0.0.0 any DNS any
• B. Permit 0.0.0.0 0.0.0.0 UDP DNS any
• C. Permit 0.0.0.0 0.0.0.0 UDP any DNS
• D. Permit any any any
• E. Permit 0.0.0.0 0.0.0.0 UDP any any

Correct answer: B, C

Explanation

The correct answers are B and C because they specifically allow UDP traffic for DNS, which is essential for the upgrade process. Options A and D do not specify the correct protocols or addresses needed for the upgrade, while option E is too permissive and does not focus on the required DNS traffic.
