• Question 441:

  Which of the following regarding IS-IS DIS is FALSE?

  A. L1 and L2 routers elect separate DIS's.
  B. DIS uses a specific Ethernet multicast address to communicate with other routers on the broadcast network.
  C. If a new router starts up in a LAN and has a higher interface priority, the new router preempts the original DIS and becomes the DIS.
  D. In broadcast multi-access networks, such as Ethernet, one router is elected as the DIS and a second router as the backup DIS.
  D. In broadcast multi-access networks, such as Ethernet, one router is elected as the DIS and a second router as the backup DIS.

• Question 442:

  On which type of IS-IS router is summarization most likely to be configured?

  A. L1 routers
  B. L2 routers
  C. L1/L2 routers
  D. L1 and L2 routers
  C. L1/L2 routers

• Question 443:

  Click on the exhibit.

  

  Router R2 has a directly connected interface to network 192.168.3.0/24 that is included in IS-IS.

  If router R4 redistributes the IS-IS route to 192.168.3.0/24 into OSPF, router R3 will receive two routes to 192.168.3.0/24. Assume that all IS-IS routers are L1/L2 capable and are in the same area.

  Which of the following is TRUE?

  A. Router R3 will install the IS-IS route in it's routing table.
  B. Router R3 will install the OSPF route in it's routing table.
  C. Router R3 will install an OSPF route and an IS-IS route in it's route table.
  D. There is not enough information to answer the question.
  A. Router R3 will install the IS-IS route in it's routing table.

• Question 444:

  Click on the exhibit button below.

  

  Is a routing policy required on PE1 to advertise a CE1's system interface to PE2?

  A. Yes. A routing policy is required to advertise routes between PE routers in a VPRN
  B. No. A routing policy is not required; the default behavior on the 7750 SR is to advertise all VPRN routes between PE routers.
  C. A routing policy is required only when BGP is used as the PE-CE routing protocol, as shown in the exhibit.
  D. A CE1 system interface can not be advertised to PE2 since the CE routers are not aware of the VPRN.
  B. No. A routing policy is not required; the default behavior on the 7750 SR is to advertise all VPRN routes between PE routers.

• Question 445:

  Once a service has been created with a customer association, it is possible to change the customer association.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 446:

  A mesh SDP is used to create an Fpipe service.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 447:

  In the topology shown, router R1 is an ASBR configured to export external routes to OSPF. Assuming that there are no stub or NSSA networks, which of the following statements regarding LSAs is true?

  

  A. Only router R1 will generate Type 4 LSAs.
  B. Only router R3 will generate Type 4 LSAs.
  C. Routers R3 and R6 will generate Type 4 LSAs.
  D. Routers R1, R3 and R6 will generate Type 4 LSAs.
  C. Routers R3 and R6 will generate Type 4 LSAs.

• Question 448:

  Click the exhibit.

  

  The output is from PE router R1 about VPRN service 100. From which protocol did router R1 learn the prefix 192.168.20.0/24?

  A. LDP
  B. BGP
  C. MP-BGP
  D. MPLS
  C. MP-BGP

  B. 2

• Question 450:

  Which of the following statements is FALSE regarding 6VPE?

  A. 6VPE is a tunneling technology that makes use of MPLS tunnels to transport IPv6 information over an IPv4 MPLS infrastructure.
  B. Customers connected to 6VPE could run native IPv6 or IPv4.
  C. On the PE router, the next hop for a VPN IPv6 address is an IPv6 address, regardless of the nature of the network between the PEs.
  D. 6VPE requires an IPv6-aware MPLS core.
  E. Both C and D are false.
  F. All of the above statements are true.
  D. 6VPE requires an IPv6-aware MPLS core.
