An engineer is troubleshooting a Primary Rate Interface that fails to come up on a H.323 production voice gateway. Layer 1 and Layer 2 configurations were validated successfully Which Cisco IOS command must be run to debug the issue with the least impact on network performance?

A.

debug vtsp session

Which actions required for a firewall configuration on a Mobile and Remote Access

through Cisco Expressway deployment?

A.

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

B.

The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061; HTTPS: TCP 8443; XMPP TCP 5222; media: UDP 36002 to 59999

C.

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

D.

The internal firewall must allow these inbound and outbound connections between

expressway - c and Expressway-e :sip;HTTPS(tunneled over SSH 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

A network administrator deleted a user from the LDAP directory of a company. The end user shows as Inactive LDAP Synchronized User in Cisco UCM. Which step is next to remove this user from Cisco UCM?

A.

Delete the user directly from Cisco UCM.

B.

Wait 24 hours for the garbage collector to remove the user.

C.

Restart the Dirsync service after the user is deleted from LDAP directory.

D.

Execute a manual sync to refresh the local database and delete the end user.

What are two functions of Cisco Expressway in the Collaboration Edge? (Choose two.)

A.

Expressway-C provides encryption (or Mobile and Remote Access but not (or business-to-business communications.

B.

The Expressway-C and Expressway-E pair can enable connectivity from the corporate network to the PSTN via a T1/E1 trunk.

C.

The Expressway-C and Expressway-E pair can interconnect H.323-to-SIP calls for voice.

D.

Expressway-E provides a VPN entry point for Cisco IP phones with a Cisco AnyConnect client using authentication based on certificates.

E.

Expressway-E provides a perimeter network that separates the enterprise network from the Internet.

Refer to the exhibit. Which route pattern can the Cisco UCM administrator apply to the configuration to allow calls to "1306.1316.1326,13*6.13#6” only?

A.

13XX

B.

13[25-8]6

C.

13!#

D.

13[A3-9)6

When designing the capacity for a Cisco UCM 12.x cluster, an engineer must decide which VMware template will be used for each node. What is the lowest number of users supported in a template and the highest number of users in a template?

A.

750 and 15.000 users

B.

750 and 10.000 users

C.

500 and 10.000 users

D.

1000 and 10.000 users

What happens to voice packets from a Cisco 8845 IP phone in the QoS trust boundary?

A.

The voice packets are not trusted, and the access layer switch reclassifies the packets.

B.

The voice packets are classified by the phone, and the classification is accepted

C.

The voice and access layer switch negotiate the classification of packets

D.

Cisco UCM determines how the voice packers are classified.

Which field is configured to change the caller ID information on a SIP route pattern?

A.

Route Partition

B.

Calling Party Transformation Mask

C.

Called Party Transformation Mask

D.

Connected Line ID Presentation

Which two features will access layer switches provide support providing high-quality voice and taking advantage of the full voice feature set? (Choose two.)

A.

Deploy RSVP to improve VoIP QoS only where it will have a positive impact on quality and functionality where there is limited bandwidth and frequent network congestion.

B.

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.

C.

Map audio and video streams of video calls (AF41 andAF42) to a class-based queue with weighted random early detection.

D.

Implement IP RTP header compression on the serial interface to reduce the bandwidth required per voice call on point-to-point links.

E.

Use 802 1Q trucking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.

What is a characteristic of video traffic that governs QoS requirements for video?

A.

Video is typically constant bit rate.

B.

Voice and video are the same, so they have the same QoS requirements.

C.

Voice and video traffic are different, but they have the same QoS requirements.

D.

Video is typically variable bit rate.
