• Question 195:

  Refer to the exhibit.

  

  An engineer is troubleshooting this video conference issue:

  1.

  A video call between a Cisco 9971 in Region1 and another Cisco 9971 in Region1 works.

  2.

  As soon as the Cisco 9971 in Region1 conferences in a Cisco 8945 in Region2, the Region1 endpoint cannot see the Region2 endpoint video. What is the cause of this issue?

  A. Cisco 8945 does not have a camera connected.

  B. Maximum Audio Bit Rate must be increased.

  C. Maximum Session Bit Rate for Video Calls is too low.

  D. Maximum Session Bit Rate for Immersive Video Calls is too low.

  Correct Answer: C

• Question 196:

  Refer to the exhibit.

  

  Cisco Unified Border Element is attempting to establish a call with Subscriber 1, but the call fails. Cisco Unified Border Element then retries the same call with Subscriber 2, and the call proceeds normally. Which action resolves the issue?

  A. Verify that the Run On All Active Unified CM Nodes checkbox is enabled.

  B. Verify that the correct calling search space is selected for the Inbound Calls section.

  C. Verify that the Significant Digits field for Inbound Calls is set to All.

  D. Verify that the PSTN Access checkbox is enabled.

  Correct Answer: A

  503 - Service Unavailable - The server's SIP service is temporarily unavailable. If CSS is missing it would not find a proper DN, and will return <404 - not found<

  Since there is no answer of several Trunks, it only explains one trunk and >Run On All Unified CM Nodes< should put in concern

• Question 197:

  A customer wants to conduct B2B video calls with a partner using an on-premises conferencing solution. Which two devices are needed to facilitate this request? (Choose two.)

  A. Expressway-C

  B. MGCP gateway

  C. Cisco Unified Border Element

  D. Cisco TelePresence Management Suite

  E. Expressway-E

  Correct Answer: AE

• Question 198:

  A company wants to provide remote users with access to its on-premises Cisco collaboration features. Which components are required to enable Cisco Mobile and Remote Access for the users?

  A. Cisco Unified Border Element, Cisco IM and Presence Server, and Cisco Video Communication Server

  B. Cisco Unified Border Element, Cisco UCM, and Cisco Video Communication Server

  C. Cisco Expressway-E, Cisco Expressway-C, and Cisco UCM

  D. Cisco Expressway-E, Cisco IM and Presence Server, and Cisco Video Communication Server

  Correct Answer: C

• Question 199:

  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 802.1Q 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.

  Correct Answer: AD

  To provide high-quality voice and to take advantage of the full voice feature set, access layer switches should provide support for:

  1.

  802.1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected

  2.

  Multiple egress queues to provide priority queuing of RTP voice packet streams

  3.

  The ability to classify or reclassify traffic and establish a network trust boundary

  4.

  Inline power capability (Although inline power capability is not mandatory, we highly recommend for the access layer switches.)

  5.

  Layer 3 awareness and the ability to implement QoS access control lists (These features are required if you are using certain IP telephony endpoints, such as a PC running a softphone application, that cannot benefit from an extended trust boundary.)

• Question 200:

  After an engineer implements the FAC and CMC features together, users report that calls take almost one minute to complete and that they occasionally hear the reorder tone. Which two actions address this issue? (Choose two.)

  B. Advise the user to hang up and try again.

  C. Advise the user to press the button after dialing the FAC and CMC codes.

  D. Change the code if the problem persists.

  E. Adjust the T302 timer from the default of 15 seconds to 5 seconds to shorten the interdigit timer.

  Correct Answer: CE
