• Question 347:

  Which RAS message is used between two gatekeepers to resolve an alias address?

  A. GRQ
  B. ARQ
  C. IRQ
  D. LRQ
  E. RRQ
  D. LRQ

  ---

  LRQ -- These messages are exchanged between gatekeepers and are used for inter-zone (remote zone) calls. For example, gatekeeper A receives an ARQ from a local zone gateway requesting call admission for a remote zone device. Gatekeeper A then sends an LRQ message to gatekeeper B. Gatekeeper B replies to the LRQ message with either a Location Confirm (LCF) or Location Reject (LRJ) message, which depends on whether it is configured to admit or reject the inter-zone call request and whether the requested resource is registered.

• Question 348:

  Which statement describes the key security service that is provided by the TLS Proxy function on a Cisco ASA appliance?

  A. It provides interworking to ensure that external IP phone traffic is encrypted, even if the rest of the system is unencrypted.
  B. It only applies to encrypted voice calls where both parties utilize encryption.
  C. It manipulates the call signaling to ensure that all media is routed via the adaptive security appliance.
  D. It enables internal phones to communicate with external phones without encryption.
  E. It protects Cisco Unified Communications Manager from rogue soft clients and attackers on the data VLAN.
  B. It only applies to encrypted voice calls where both parties utilize encryption.

  ---

  TLS Proxy is typically deployed in front of Cisco Unified Communications Manager and other unified communications application servers that utilize media encryption. TLS Proxy is not designed to provide remote-access encryption services for remote phones or client endpoints. Other solutions such as Cisco ASA Phone Proxy or IP Security/Secure Sockets Layer (IPsec/SSL) VPN services are more appropriate. TLS Proxy is not designed to provide a secure campus soft phone solution where the requirement is to provide secure data to phone VLAN traversal or for proxying connections to Cisco Unified Communications Manager.

• Question 349:

  Refer to the exhibit.

  

  Assume that all shown agents are available to take a call. Which agent will receive the call when a select resource step is triggered in the script for the Customer Service CSQ?

  A. s1dispatch-PA
  B. s1dispatch-OH
  C. the agent that has been idle the longest
  D. the agent with the shortest handled time
  A. s1dispatch-PA

  ---

  The Contact Service Queue (CSQ) controls incoming calls by determining where an incoming call should be placed in the queue and to which agent the call is sent.

  After you assign an agent to a resource group and assign skills, you need to configure the CSQs.

  You assign agents to a CSQ by associating a resource group or by associating all skills of a particular CSQ. Agents in the selected resource group or who have all the selected skills are assigned to the CSQ. Skills within the CSQ can be

  ordered. This means, when resources are selected, a comparison is done based on the competency level (highest for "most skilled" and lowest for "least skilled") of the first skill in the list. If there is a "tie" the next skill within the order is used,

  and so on.
