• Question 361:

  Based on the 802.3ae definition, which capability is a function of WIS?

  A. interoperability on the same link with POS, by adapting the Ethernet MAC frames to be based on a serial protocol such as PPP.
  B. line clocking based on the synchronous nature of the POS requirements either clocking when the interface is connected back to back or external clocking when connected through DWDM.
  C. an equivalent POS optical and electrical signal on SONET/SDH protocols and APS to restore link failures in 50 ms.
  D. ability for WAN-PHY equipment to generate an Ethernet data stream to map to an OC-192 concatenated payload at the PHY level, without any MAC layer processing.
  D. ability for WAN-PHY equipment to generate an Ethernet data stream to map to an OC-192 concatenated payload at the PHY level, without any MAC layer processing.

• Question 365:

  A service provider with MPLS traffic-eng tunnels is supporting multicast traffic that uses RPF to ensure the source of the sender. The unicast routing table points the source through TE, which does not support multicast and RPF fails.

  Which action fixes the issue?

  A. Use auto-route announce under MPLS TE.
  B. Use multicast-intact under IGP.
  C. Use IGMP snooping.
  D. Use CGMP.
  B. Use multicast-intact under IGP.

  C. Layer 3 protocol type
  D. TCP sequence number
  E. EtherType
  F. input logical interface
  B. type of service
  C. Layer 3 protocol type
  F. input logical interface

• Question 367:

  Select the three best answers which best describe Private Network-to Network Interface (PNNI) in an ATM network (Choose three.)

  A. It is the Routing protocol used between ATM switches
  B. PNNI uses the same Dijsktra algorithm for SPF calculation
  C. PNNI and OSPF use the same Database to make cohesive decision for packet forwarding
  D. PNNI measures line capacities and delays in addition to simple cost metrics
  A. It is the Routing protocol used between ATM switches
