NEW QUESTION # 44
A company has enabled ICE to optimize call flows and improve video quality between their Cisco Collaboration endpoints internally and externally.
For which reason would you see activity on the TURN server when a call is established between two external endpoints?

  • A. ICE cannot reduce the packet loss on the link
  • B. The video call is using 4K resolution, which is not supported by ICE with CUCM 12.5
  • C. A STUN cannot punch holes in the firewall
  • D. The video call is using encryption, which is not supported by ICE with CUCM 12.5

Answer: C


NEW QUESTION # 45

Refer to the exhibit. When configuring a search rule that routes calls to a zone, what occurs when 13358 is dialed?

  • A. 13358 is replaced by 135 and remains in the same zone.
  • B. 13358 is replaced by 135, and then is sent to the traversal zone.
  • C. 13358 is sent directly to the traversal zone.
  • D. 13358 is replaced by 135, and then is sent to the local zone.

Answer: B


NEW QUESTION # 46
What happens to the encrypted signaling traffic of a collaboration device if you place it inside a firewall with private IP addresses and try to make a call over IP without any collaboration infrastructure?

  • A. Encrypted IP traffic for collaboration devices always is trusted by the firewall.
  • B. The signaling makes it back to the endpoint because the firewall is an application layer gateway and provides address translation.
  • C. The signaling does not make it back to the endpoint because the firewall cannot inspect encrypted traffic.
  • D. The signaling makes it back to the endpoint because the endpoint sent the private address to the external endpoint.

Answer: C

Explanation:
A NAT ALG is similar to a firewall ALG, but a NAT ALG actually changes (maps) the addresses and ports in the signaling messages. The NAT ALG cannot inspect the contents of encrypted signaling messages.


NEW QUESTION # 47
A Cisco Webex Hybrid Video Mesh Node can be installed in the DMZ and on the internal network.
Which statement is true?

  • A. Installing a Video Mesh Node in the DMZ requires you to open TCP and UDP port 4444 in your internal firewall for full clustering functionality.
  • B. Webex Cloud supports either a DMZ-based Mesh Node for security or an internal-based Mesh Node for media control only.
  • C. Using internal Video Mesh Node also works due to Mobile and Remote Access setup for Webex Teams clients. A DMZ node is added for extra security.
  • D. Installing a Video Mesh Node in the DMZ requires the external firewall to allow UDP traffic from ANY port to the address of the Video Mesh Nodes via port 5004.

Answer: D

Explanation:
The external firewall will need to allow UDP traffic from ANY port to the address of the Video Mesh Nodes via port 5004, so that roaming Webex Teams endpoints can send media to the nodes. This is not a preferred approach.

  • E. When Expressway Core works with VMN clusters, Expressway Core decides which VMN is used for signaling/media connection.

Answer: C,D

NEW QUESTION # 55
A company is installing Cisco Collaboration infrastructure and one of the requirements is that they must be able to communicate with many external parties that are using H.323 and SIP. Internally they want to register the endpoints only on SIP.

  • A. Video Mesh Cluster-2
  • B. Both Cloud Node US-EAST and US-WEST
  • C. Cloud Node US-EAST
  • D. Cloud Node US-WEST

Answer: A

"Which cluster is used also depends on latency rather than just location. For example, a cloud cluster with lower STUN round-trip (SRT) delay than a Webex Video Mesh cluster may be a better candidate for the meeting. This logic prevents a user from landing on a geographically far cluster with a high SRT delay".


NEW QUESTION # 57
Refer to the exhibit. What is the result of a transformation applied to alias 88514?

Answer: D

Explanation:
The answer should be [email protected], since the regex considers anything after digit 8 (excludes 1-7), leaves the rest intact, and replaces the domain. So in short terms, it simply adds the domain after the DN.


NEW QUESTION # 58
How is the communication routed in a Hybrid deployment so that people on Cisco Cloud-Based IM are able to communicate with Cisco Jabber users in the on-premises environment?

  • A. The Expressway-E located in the DMZ establishes a connection with the Cisco Webex Cloud to enable the hybrid service and allow the two services to communicate.
  • B. The Expressway-C enables a connection directly with the Cisco Webex Cloud to enable the hybrid service and allow the two services to communicate.
  • C. The Cisco UC server establishes a connection using the outgoing path through the Cisco Expressways that terminates in the Cisco Webex Cloud to create the hybrid environment that links the two services together.
  • D. The Cisco Unified IM and Presence server establishes a connection using the outgoing path through the Cisco Expressways that terminates in the Cisco Webex Cloud to create the hybrid environment that links the two services together.

Answer: B


NEW QUESTION # 59
In a Mobile and Remote Access deployment, where must communications be encrypted with TLS?

  • A. Cisco Expressway-C, Cisco Expressway-E, and endpoints outside the enterprise
  • B. Cisco Expressway-E and endpoints outside the enterprise
  • C. Cisco Expressway-C, Cisco Expressway-E, and Cisco Unified Communications Manager
  • D. Cisco Expressway-C, Cisco Unified Communications Manager, and IM&P

Answer: A

Explanation:
All signaling between the Cisco Expressway-E and the external endpoints must be encrypted and depending on the endpoint software version, traffic must also be authenticated with certificates.
The communication between the Cisco Expressway-C and the Cisco Expressway-E must always be encrypted and authenticated using server certificates from both servers.
MRA requires secure communication between Expressway-C and Expressway-E, and between Expressway-E and external endpoints.
