According to the information given in the figure, which of the following descriptions of the IPv6 routing information calculated by the R router through ISIS is correct?
- A . R4 has no IS-IS routing entry
- B . R4 has 2 equal-cost IS-IS default routes
- C . R4 has 2 non-equivalent IS-1S default routes
- D . R4 has 1 1S-IS default route
Which of the following descriptions of MPLS label space is wrong?
- A . When the penultimate hop LSR performs label exchange, if it is found that the exchanged label value is 3, the label will be popped up by default and the packet will be sent to the last hop.
- B . 16~1023 is the label space shared by static LSP and static CR-LSP
- C . If the outgoing label value is 0, the router will directly discard the packet.
- D . Above 1024 is the label space shared by dynamic signaling protocols such as LDP, RSVP-TE, MP-BGP and so on.
Part of the configuration of device H is as shown in the figure. Which item is wrong in the following description of this configuration?
- A . Configure GigabitEthernet0/0/1 interface as a trusted interface
- B . Enable DHCP Snooping configuration to prevent ARP spoofing attacks
- C . If the DHCP request message received by the GigabitEthernet0/0/1 interface does not contain the SubOption information of Option82, the device will generate Option82 and insert it into the message.
- D . Enabling DHCP Snooping configuration can be used to prevent DHCP Server bogus attacks.
Which of the following descriptions of BGP/MPLSIPVPN routing interactions is wrong?
- A . PE and CE exchange IPv4 routing information.
- B . The egress PE can send IPv4 routes to the remote CE through BGP, IGP or static routing.
- C . The ingress PE changes the IPv4 routes received from the CE into VPNv4 routes and saves them according to different VPN instances.
- D . After receiving the VPNv4 routes advertised by the ingress PE, the egress PE filters the VPNv4 routes based on the RT attributes carried by the routes.
An interface has the following configuration: isitimerhello5level-2. Which of the following descriptions is correct?
- A . The CSNP packet sending interval for Level-2 on this interface is 5s.
- B . The hello packet sending interval for Level- on this interface is 5s.
- C . The hello packet sending interval for Level -2 of this interface is 5s.
- D . The hello packet sending interval for Level-1 and Level-2 of this interface is both 5s.

- B . The Type1 LSA generated by R2 in area 0 contains the routing information of 10.0.2.2/32
- C . The Type2 LSA generated by R2 in area 0 contains the routing information of 10.0.2.2/24
- D . The Type3 LSA generated by R2 in area 0 contains the routing information of 10.0.2.2/32
As shown in the figure is the output information of a network engineer when troubleshooting OSPF faults.
