Which of the following will not cause the VRRP backup group to flap?
정답: A
The rollback operation of project cutover can be temporarily determined according to the situation during cutover, and no advance plan is required.
정답: A
Which of the following aspects should be considered in the cutover risk assessment? (Multiple choice)
정답: A,B,C,D
BGP4+ carries the next hop address of the IPv6 route through the Next Hop attribute in the Update packet.
정답: B
Which of the following belong to the delivery process of dry MPLS VPN routes? (Multiple choice)
정답: A,B,C,D
Traditional BGP-4 can only manage IPV4 unicast routing information. MP-BGP extends BGP-4 in order to provide support for multiple network layer protocols. The feature that MP-BGP supports for IPv6 unicast networks is called BGP4+, and BGP4+ carries the next hop address information of the route through the Next Hop attribute.
정답: B
By viewing DHCP configuration information and packet statistics, you can view the running status of the device and the count of DHCP packets received and sent, so as to locate problems during routine maintenance. Which of the following commands can be used to view DHCP messages directly? (Multiple choice)
정답: A,B,C
Configure IS-IS IPv6 enable on the interface. What is the meaning of this command?
정답: A
Link state information between different ISIS processes of two routers is isolated by default.
정답: A
The DHCP protocol can assign some TCP/IP-related parameter information to the client. In this process, DHCP defines a variety of messages. The encapsulation of these messages is?
정답: D
As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator's BGP/MPLS IPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PE1 has advertised the route of network segment 192.168.1.0/24 in Site1 to PE2 through the MPLS BGP neighbor relationship, and the route learning is normal.
When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Site1, what should be the outermost label?
When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Site1, what should be the outermost label?
정답: C
BGP/MPLS IP VPN can only use LDP to build a public network channel.
정답: A
As shown in the figure, a campus has deployed IPv6 for service testing, and there are 4 routers in the network.
Run OSPFV3 to realize network interconnection.
Which of the following statements is false about the LSA generated by this OSPFv3 network?
Run OSPFV3 to realize network interconnection.
Which of the following statements is false about the LSA generated by this OSPFv3 network?
정답: C
Which of the following is not a preliminary preparation for the cutover plan?
정답: C
Link LSA of OSPFv3 are propagated throughout the area.
정답: B
OSPF fast convergence is an extended feature to improve the speed of routing convergence. The working principle of PRC (Partial Route Calculation) is: when the network topology changes, only path calculation is performed on the affected nodes, thereby speeding up route computation.
정답: A
Which of the following description is wrong? (Multiple choice)
