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

• Video is typically constant bit rate.
• Voice and video are the same, so they have the same QoS requirements.
• Voice and video traffic are different, but they have the same QoS requirements.
• Video is typically variable bit rate.

An engineer with ID012345678 must build an international dial plan in Cisco UCM. Which action is taken when building a variable-length route pattern?

• configure single route pattern for international calls
• set up all international route patterns to 0.!
• reduce the T302 timer to less than 4 seconds
• create a second route pattern followed by the # wildcard

What is the purpose of Mobile and Remote Access (MRA) in the Cisco UCM architecture?

• MRA is used to access Webex cloud services only if authenticated with on-premises LDAP service.
• MRA is used to make secure PSTN calls by Cisco UCM only while on-premises authentication.
• MRA is used to make B2B calls through Expressway registration.
• MRA is used to access the collaboration services offered by Cisco UCM from off-premises network connections

The security department will audit an IT department to ensure that the proper guidelines are being followed. The reports of the call detail records show unauthorized access to PSTN. Which two actions should an administrator check to prevent the unauthorized use of the telephony system? (Choose two.)

• Ensure that ad hoc conference calls are dropped if an external user is add.
• Call forward settings (ALL/Busy/No Answer) are restricted to internal extensions in the network
• Add an additional firewall between the Cisco UCM server and the Expressway Core server.
• For extension mobility, logged-out CSS is restricted to internal extensions and emergencies.
• Forced authorization code is used to recognize a dialing extension and authorize an international call.

What is an indicator of network congestion in VoIP communications?

• jitter increase due to variable delay
• discards in the interface of routers and switches
• video loss due to video frame corruption
• gaps in the voice due to packet loss

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

• 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.
• Use 802, 1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.
• Implement IP RTP header compression on the serial Interface to reduce the bandwidth required per voice call on point-to-point links.
• 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.
• Map audio and video streams of video calls (AF41 and AF42) to a class-based queue with weighted random early detection.

A Cisco UCM administrator wants to enable the Self-Provisioning feature for end users. Which two prerequisites must be met first? (Choose two.)

• Cisco Extended Functions service must be running
• End users must belong to Standard CCM Admin Users group, the Standard CCM End Users group, and the Standard CCM Self-Provisioning group.
• End users must have a primary extension.
• End users must be associated to a user profile or feature group template that includes a universal line template and universal device template.
