• Question 132:

  Many transition technologies have been adopted to replace IPv4 addresses on networks with IPv6 addresses. These technologies are categorized into IPv4/IPv6 coexistence technologies and IPv4/IPv6 interoperability technologies. Which of the following technologies are considered to be IPv4/IPv6 coexistence technologies?

• Question 133:

  Regarding the logical mode of the MPLS TTL pair, is the following description correct?

  A. Pipe IP MPLS IP TTL 1 In MPLS TTL mode, when the message passes through the network, it is mapped to the field at the ingress point.
  B. MPLS TTL IP TTL MPLS A label, which has the same function as the header, can prevent the network from routing the loop (as it is)
  C. Uniform IP MPLS IP TTL 1 MPLS TTL mode is simulated. When the message passes through the network, the entry point is reduced and the field is fixed to the value.
  D. In the case of the MPLS VPN MPLS Ingress uniform, the private network text can be used in the reporting mode.
  B. MPLS TTL IP TTL MPLS A label, which has the same function as the header, can prevent the network from routing the loop (as it is)

• Question 136:

  Which of the following statements regarding BGP confederations is false?

  A. By default, sub-AS numbers of a confederation are advertised to BGP peers outside the confederation.
  B. A BGP confederation divides an AS into several sub-ASs. ASs outside a confederation still consider the confederation as an AS.
  C. Confederations can easily detect routing loops inside an AS because EBGP is run between sub-ASs.
  D. Sub-A5s within a BGP confederation can use private AS numbers. For Huawei NE and AR routers, a maximum of 32 sub-ASs can be configured in a BGP confederation.
  A. By default, sub-AS numbers of a confederation are advertised to BGP peers outside the confederation.
