• Question 118:

  What are the two differences between the IntServe and DiffServ models of QoS? (Choose two.)

  A. DiffServ provides absolute QoS guarantees.
  B. IntServ is the default QoS mechanism for all routers, because applications signal the router with the QoS level they require.
  C. DiffServ inherits the connection-oriented approach from telephony network design. Every individual communication must explicitly specify its traffic descriptor and requested resources to the network.
  D. With IntServ, packet delivery is guaranteed. However, the use of IntServ can severely limit the scalability of a network.
  E. DiffServ was designed to overcome the limitations of both the best-effort and IntServ models and can provide an "almost guaranteed" QoS.
  D. With IntServ, packet delivery is guaranteed. However, the use of IntServ can severely limit the scalability of a network.
  E. DiffServ was designed to overcome the limitations of both the best-effort and IntServ models and can provide an "almost guaranteed" QoS.

• Question 120:

  How does the Cisco Unified Communications Manager Express match an outbound VoIP dial peer?

  A. Outbound dial-peer matching uses the entire string of digits en bloc to match the dial peer with the longest match.
  B. Outbound dial-peer matching is completed on a digit-by-digit basis.
  C. It matches outbound dial peers by placing all the dial peers into a hunt group and then uses the entire dialed number en bloc to match the first dial peer.
  D. Cisco Unified Communications Manager Express creates a hunt group that contains all the configured dial peers and then applies the dial digits in a digit-by-digit manner to match a dial peer.
  A. Outbound dial-peer matching uses the entire string of digits en bloc to match the dial peer with the longest match.
