Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?
The traversal zone on Expressway-C points to Expressway-E through the peer address field on the traversal zone, which specifies the Expressway-E server address. For dual NIC deployments, set the Expressway-E address using an FQDN that resolves the IP address of the internal interface
The internal firewall must allow these inbound and outbound connections between Expressway-C and Expressway-E. SIP: HTTPS (tunnelled overSSH between C and E): TCP 2222; TCP 7001; Traversal Media: UDP 2776 to 2777 (or 36000 to 36011 for large VM/appliance): XMPP: TCP 7400.
The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061; HTTPS:
TCP 8443: XMPP: TCP 5222; Media: UDP 36002 to 59999.
Do not use a shared address for Expressway-E and Expressway-C, as the firewall cannot distinguish between them If static NAT for IP addressing on Expressway-E is used, ensure that any NAT operation on Expressway-C does not resolve the same traffic IP address Shared NAT is not supported.
Which characteristic of distributed class-based weighted fair queueing addresses jitter prevention?
lt provides additional granularity by allowing a user to create classes
It minimizes jitter by implementing a priority queue for voice traffic
It uses a priority queue for voice traffic to avoid jitter
It provides additional granularity by allowing a user to define custom classes
A company hosts a conference call with no local users How does the administrator stop the conference from continuing?
modifies the Block OffNet to OffNet Transfer service parameter
removes the transcoder
changes the codecs that are supported on the conference resource
modifies the Drop Ad Hoc Conference service parameter
What happens to voice packets from a Cisco 8845 IP Phone in the QoS trust boundary?
The phone and access layer switch negotiate the classification of packets
The voice packets are classified by the phone, and the classification is accepted.
Cisco UCM determines how the voice packets are classified
The voice packets are not trusted, and the access layer switch reclassifies the packets.
Refer to the exhibit.
