Cisco 400-051 Exam

Which statement describes the key security service that is provided by the TLS Proxy function on a Cisco ASA appliance?

  • A. It provides interworking to ensure that external IP phone traffic is encrypted, even if the rest of the system is unencrypted.
  • B. It only applies to encrypted voice calls where both parties utilize encryption.
  • C. It manipulates the call signaling to ensure that all media is routed via the adaptive security appliance.
  • D. It enables internal phones to communicate with external phones without encryption.
  • E. It protects Cisco Unified Communications Manager from rogue soft clients and attackers on the data VLAN.
Answer: Option B.
Explanation: 

TLS Proxy is typically deployed in front of Cisco Unified Communications Manager and other unified communications application servers that utilize media encryption. TLS Proxy is not designed to provide remote-access encryption services for remote phones or client endpoints. Other solutions such as Cisco ASA Phone Proxy or IP Security/Secure Sockets Layer (IPsec/SSL) VPN services are more appropriate. TLS Proxy is not designed to provide a secure campus soft phone solution where the requirement is to provide secure data to phone VLAN traversal or for proxying connections to Cisco Unified Communications Manager.
