    F. Bind the network PRIs to add additional bandwidth.

  • Question 143:

    Cisco TelePresence System EX90 #1 is trying to call EX90 #2. Both endpoints are registered to Cisco Unified Communications Manager. The call connects, but the quality is not good. The video image is breaking up on EX90 #2. The media path from A to B supports only 2 Mb. Which three reasons are possible causes? (Choose three.)

    A. The camera on system B has a loose cable.
    B. The line is congested, and QoS is not configured correctly between the sites.
    C. Bandwidth limitation between IP zones is set too low for video.
    D. Bandwidth limitation between regions is set too low for video.
    E. The autonegotiation protocol H.286 is turned off on one of the EX90s.
    F. The system is set to use a higher bandwidth that the media path allows.

  • Question 144:

    URI dialing is enabled between two clusters with the default options. The engineer that set up the URI dialing verified that all was working properly. However, a user from one of the clusters cannot dial using URI to a user in the same cluster. What do you do to resolve this issue?

    D. The Cisco IP Voice Media Streaming Application can reduce the performance of the Cisco Unified Communications Manager it is installed on the same server.
    E. When you configure and restart the MTP, the changes are applied immediately to active calls.
    F. When you configure and reset the MTP, the changes are applied immediately to active calls.

  • Question 146:

    You are trying to register an H.323-based Cisco TelePresence system to Cisco Unified Communications Manager and a Cisco DX70 system to the Cisco VCS Control. Why do neither of the units want to register?

    A. The H.323-based system needs an E164 number to register to Cisco Unified Communications Manager, and the Cisco DX70 needs to have the MAC address configured first on the Cisco VCS Control.
    B. The H.323-based system needs to register to the Cisco VCS Control with an E.164 number, and the Cisco DX70 needs the TFTP address to register on the Cisco Unified Communications Manager.
    C. Both systems need to register to the Cisco VCS Control, but the H.323-based system needs to have the gatekeeper setting set to "Direct."
    D. Both systems need to register to the Cisco Unified Communications Manager, as the Cisco VCS Control is used only for firewall traversal.
    E. You need Cisco TelePresence Management Suite to register Cisco TelePresence systems.
    F. You need Cisco TelePresence Server to register Cisco TelePresence systems.
