第4题：
You want to implement router redundancy in the Company network using the best method available. Which protocol specified by RFC 2281 provides network redundancy for IP networks， ensuring that user traffic immediately and transparently recovers from first-hop failures in network edge devices or access circuits？（）
第5题：

第6题：
During testing of network redundancy in a fully meshed enterprise campus， a problem has been reported. Both distribution multilayer switches are fully configured for redundancy； clients operate normally when the primary multilayer distribution switch is operating. All clients drop connections outside of their respective access layer group when the primary distribution switch is shut down and the secondary distribution switch is still operational. Additional information indicates that the secondary distribution switch is able to ping major corporate and Internet locations. Which item would be the best point of troubleshooting for this connectivity issue？ （）

C. redundancy, mode sso, show redundancy states
D. show redundancy states, redundancy, mode sso
第9题：
Which two statements are true regarding redundancy groups? （）(Choose two.)
