Which of the following commands can be used to view BGP VPNv4 routing and BGP private network routing information on the PE?

  1. display bgp routing-table address-family vpnv4
  2. display bgp vpnv4 routing-table
  3. display bgp routing-table ipv4-family vpnv4
  4. display vpnv4 bgp routing-table

Answer(s): B



Regarding BGP/MPLS IPVPN data forwarding, which of the following descriptions is wrong?

  1. When data is transmitted on the BCP/MPLS IPVPN backbone network, it always carries two layers of labels
  2. The inner label during data forwarding is assigned by MP-BGP
  3. The outer label during data forwarding can be allocated by LDP
  4. The data sent by the PE to the CE is an IPv4 packet

Answer(s): A



Regarding BGP/MPLS IPVPN routing interaction, which of the following descriptions is wrong?

  1. The egress PE can send IPv4 routes to the remote CE through BGP, IGP or static routing
  2. After the egress PE receives the VPNv4 route advertised by the ingress PE, it filters the VPNv4 route according to the RT attribute carried by the route
  3. The exchange between PE and CE is IPv4 routing information
    -D. The ingress PE changes the IPv4 route received from CE to VPNv4 route, and saves it according to different VPN instances
    -

Answer(s): A



Which of the following descriptions is wrong?

  1. The LSP established by statically assigning labels can also be dynamically adjusted according to network topology changes without the intervention of the administrator
  2. The principle to be followed for manual label allocation is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node
  3. LSP is divided into static LSP and dynamic LSP. The static LSP is manually configured by the administrator, and the dynamic LSP is dynamically established using the label protocol
  4. Dynamic LSP is dynamically established through label distribution protocols, such as MP-BGP, RSVP-TE,
    -LDP

Answer(s): A

  2. Fragment offset
  3. Application Protocol
  4. Destination Address

Answer(s): B



What is the flooding scope in OSPFv3 for the LSA in the entire autonomous system?

  1. Link-LSA
  2. As-external-LSA
  3. Inter-Area-Prefix-LSA
  4. Intra-Area-Prefix-LSA

Answer(s): D



When troubleshooting MSTP, you executed the display current-configuration command to obtain the configuration file of the device.
Which of the following statements is wrong?

  1. No matter whether the BPDU Tunnel is configured on the device or not, MSTP will not affect it correctly
  2. Whether the MSTP port connected to the user terminal device is disabled or configured as an edge port
  3. Check the port configuration to confirm whether the MSTP-enabled port is enabled with the protocol message sending command. Such as: bpdu enable
  4. Check whether the port is added to the correct WLAN

Answer(s): A



If the display current-configuration can reach the IS-IS configuration, but there is no IS-IS configuration in the display saved-configuration, what does it mean?

  1. The IS-IS configuration that the Flash is running is not saved to the memory
  2. The running IS-IS configuration in the memory has been saved to the Flash
  3. No IS-IS command is entered
  4. The running IS-IS configuration of the memory is not saved to the Flash

Answer(s): D
