- C. Restart the NTP service on Cisco UCM.
- D. Delete the original NTP server from Cisco UCM.
Answer : D
Refer to the exhibit.
A collaboration engineer adds a redundant NTP server to an existing Cisco Collaboration solution. On the Cisco UCM OS Administration page, the new NTP server shows as `Not Accessible`. Which action resolves this issue?
- A. Delete and re-add the new NTP server via the Cisco UCM command-line interface.
- B. Start the NTP service on the new NTP server.
- C. Configure the ג€reachג€ value as ג€377ג€ for the new NTP server.
- D. Restart NTPD on the Cisco UCM server.
Answer : A
Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?
- A. The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061: HTTPS: TCP 8443; XMPP: TCP 5222; Media: UDP 36002 to 59999.
- B. The internal firewall must allow these inbound and outbound connections between Expressway-׀¡ and Expressway-E: SIP: HTTPS (tunneled over SSH between ׀¡ and E): TCP 2222: TCP 7001; Traversal Media: UDP 2776 to 2777 (or 36000 to 36011 for large VM/appliance); XMPP: TCP 7400.
- C. Do not use a shared address for Expressway-E and Expressway-׀¡, 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-׀¡ does not resolve the same traffic IP address. Shared NAT is not supported.
- D. The traversal zone on Expressway-׀¡ 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.

To provide high-quality voice and take advantage of the full voice feature set, which two access layer switches provide support? (Choose two.)
- A. Use multiple egress queues to provide priority queuing of RTP voice packet streams and the ability to classify or reclassify traffic and establish a network trust boundary.
- B. Deploy RSVP to improve VoIP QoS only where it can have a positive impact on quality and functionality where there is limited bandwidth and frequent network congestion.
- C. Map audio and video streams of video calls (AF41 and AF42) to a class-based queue with weighted random early detection.
- D. Use 802.1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.
- E. Implement IP RTP header compression on the serial interface to reduce the bandwidth required per voice call on point-to-point links.
