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?

  1. Delete and re-add the new NTP server via the Cisco UCM command-line interface.
  2. Start the NTP service on the new NTP server.
  3. Configure the '''?reach'''? value as '''?377'''? for the new NTP server.
  4. Restart NTPD on the Cisco UCM server.

Answer(s): A



Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?

  1. The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061: HTTPS: TCP 8443; XMPP: TCP 5222; Media: UDP 36002 to 59999.
  2. The internal firewall must allow these inbound and outbound connections between Expressway-С and Expressway-E: SIP: HTTPS (tunneled over SSH between С and E): TCP 2222: TCP 7001; Traversal Media: UDP 2776 to 2777 (or 36000 to 36011 for large VM/appliance); XMPP: TCP 7400.
  3. Do not use a shared address for Expressway-E and Expressway-С, 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-С does not resolve the same traffic IP address. Shared NAT is not supported.
  4. The traversal zone on Expressway-С 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.

Answer(s): A

The IP phones at a customer site do not pick an IP address from the DHCP. An engineer must temporarily disable LLDP on all ports of the switch to leave only CDP. Which two commands accomplish this task? (Choose two.)

  1. Switch(config)# no lldp transmit
  2. Switch# configure terminal
  3. Switch# copy running-config startup-config
  4. Switch(config)# no lldp run
  5. Switch(config)# interface GigabitEthernet1/0/1

Answer(s): B,D



To provide high-quality voice and take advantage of the full voice feature set, which two access layer switches provide support? (Choose two.)

  1. 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.
  2. 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.
  3. Map audio and video streams of video calls (AF41 and AF42) to a class-based queue with weighted random early detection.
  4. Use 802.1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.
  5. Implement IP RTP header compression on the serial interface to reduce the bandwidth required per voice call on point-to-point links.

Answer(s): A,D
