2. Unlike STP, RSTP has only one BPDU type, the value is 2, and there is no TCN BPDU.

3. As shown in the figure, Client1, Client2, and Client3 serve as clients of RR1 at the same time, and R1 introduces 10 routes.

Assuming that the BGP configuration is correct and all neighbor relationships have been established, how many routing entries exist in the BGP routing table of Client3?

4. OSPFv3 adopts the same route advertisement method as OSPFv2: it is advertised through the network command in the OSPFv3 area view.

5. In the topology shown in the figure, what type of LSA will not be generated on R1 when the entire network runs OSPFv3 without importing external routes?

6. IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculation. As shown in the figure, a campus deploys both IPv4 and IPv6, also runs IS-IS to achieve network interconnection. R2 only supports IPv4.

7. Which of the following parameters are not required when configuring BGP peers? (Multiple Choice)

8. Link state information is isolated by default between different IS-IS processes on the same router.

9. Which of the following statements about the multicast address used by 0SPFv3 is correct? (Multiple Choice)

10. As shown in the figure, PE1 and PE2 exchange private network routing information with their CEs through OSPF, and the same Domain ID is configured on PEI and PE2.

When importing routes from BGP to OSPF on PE2, which of the following types of LSAs may be passed to CE2? (Multiple Choice)

11. A medium-sized campus network manages the network through the SNMP protocol. The campus has high network security.

Which SNMP version is recommended for management?

12. In a VXLAN network, which can realize traffic access to the VXLAN network, and can also be used for communication with the same subnet in the same XLAN network?

13. What are the problems with manually creating static VXLAN tunnels in a campus network? (Multiple Choice)

14. The DHCP protocol can assign some TCP/IP-related parameter information to the client. In this process, DHCP defines a variety of packets. The encapsulation protocol used by these packets at the transport layer is:

15. After a switch is powered on, it joins a running stack system. This behavior is called stack join.

16. In the multi-level RR scenario, a large number of secondary RRs will be connected to the primary RR, which may cause the BGP routing table of the primary RR to overflow.

What method can be used to reduce the risk of overflowing the the primary RR BGP routing table?

19. Which of the following statements about the IS-IS protocol is false?

20. BGP authentication can prevent illegal routers from establishing neighbors with BGP routers. BGP authentication can be divided into MD5 authentication and Keychain authentication.

Which of the following BGP packets will carry BGP Keychain authentication information? (Multiple Choice)

21. MPLS is called Multi-Protocol Label Switching, which is correct about the label description in MPLS? (Multiple Choice)
