  B. Configure the switch port to use a manual speed and duplex setting of 100 Mbps and half duplex, and keep the collaboration endpoint setting as "auto."
  C. Keep both the switch port and collaboration endpoint settings as "auto," because this configuration is not responsible for the mismatched settings that were reported.
  D. Set both the collaboration endpoint and the switch port to use manual speed and duplex settings of 100 Mbps and full duplex.
  D. Set both the collaboration endpoint and the switch port to use manual speed and duplex settings of 100 Mbps and full duplex.

• Question 299:

  A company has a headquarters and a remote site. Cisco Unified Communications Manager (CUCM) acts as a DHCP server. Both sites use their local voice gateways tor PSTN calls. At the headquarters site, the PSTN prefix is 9, and the emergency number is 911. At the remote site, the PSTN prefix is 0, and the emergency number is 112. Here are the deployment policies for roaming devices:

  1.

  Softphones can roam between two sites.

  2.

  A roaming softphone uses the local gateway for all PSTN calls.

  3.

  The user keeps home dial habits on a roaming softphone, with the exception of the emergency number.

  When a headquarters user uses a softphone at the remote site, prefix 9 can be used to make PSTN calls via voce gateway in the remote site, but emergency number 112 does not work. Which setting on CUCM should be checked?

  A. Device Mobility Group
  B. Physical Location
  C. DHCP subnet
  D. Device Mobility Info
  D. Device Mobility Info

• Question 300:

  Users of your local Cisco Unified Communications Manager cluster report that they receive error "Login is unavailable (23)" when they try to log in to Extension Mobility. Which reason for this error is true?

  A. User provided the wrong UserID or PIN
  B. User has no Extension Mobility profiles assigned.
