Question 7

On a newly deployed routerWRED is configured on HW., which of the following descriptions about WRED features is correct? (multiple choice) ( confirmed)

Select all that apply, then click Submit answer.

  • ○

    WREDDifferent drop thresholds and packet loss rates can be set for packets with different priorities
  • ○

    When traffic exceeds a minimum threshold, WRED starts dropping all ingress traffic (tail drop)
  • ○

    Avoid global synchronization by selectively dropping multiple TCP streams
  • ○

    Low-bandwidth traffic is more likely to drop than high-bandwidth traffic
Question 8

As shown in the figure, redundant links are used to establish IPse between the branch and the headquartersc VPN, and enable traffic from branch 1 on Router_B at the same time URPF, which of the following statements is true?

Select all that apply, then click Submit answer.

  • ○

    When using IPsec master and backup link redundancy backup, enable it on the physical interfaceURPF function, it is recommended to use URPF loose mode.
  • ○

    When using IPsec multi-link redundancy backup, it is possible toURPF function, you can use URPF strict mode
  • ○

    When using IPsec multi-link redundancy backup, enable it on the tunnel interfaceURPF function, you can use URPF strict mode.
  • ○

    When using IPsec master and backup link redundancy backup, enable it on the physical interfaceURPF function, you can use URPF strict mode.
Question 9

Which of the following statements about the tail of ISIS protocol LSP packets is correct?

Select all that apply, then click Submit answer.

  • ○

    LSP fast diffusion feature, first diffuse LSPs less than the specified number to speed up the synchronization process of LSDB
  • ○

    by configurationAn intelligent timer generated by LSP, which can automatically adjust the delay time according to the changing frequency of routing information
  • ○

    When the link state information increases, the packet length of the LSP can be increased, so that each LSP can carry more information.
  • ○

    Decreasing the minimum time interval for sending LSPs by port can speed up the diffusion of LSPs.
