SNCF — Securing Networks with Firepower — Question 131

Remote users who connect via Cisco AnyConnect to the corporate network behind a Cisco FTD device report that they get no audio when calling between remote users using their softphones. These same users can call internal users on the corporate network without any issues. What is the cause of this issue?

Answer options

• A. FTD has no NAT policy that allows outside to outside communication.
• B. Split tunneling is enabled for the Remote Access VPN on FTD.
• C. The hairpinning feature is not available on FTD.
• D. The Enable Spoke to Spoke Connectivity through Hub option is not selected on FTD.

Correct answer: A

Explanation

The correct answer is A because without a proper NAT policy, outside-to-outside communication is blocked, preventing audio from functioning between remote users. Option B is incorrect as split tunneling typically allows for direct internet access and wouldn't affect audio. Option C is also wrong since hairpinning is not necessary for this scenario, and option D does not pertain to audio issues but rather to VPN connectivity settings.
