Question 126

Qing technology is a technology to expand VLAN space. It can achieve the function of expanding Vian space by adding a layer of 8D2.1Q Tag on the basis of 8Q2.12 tag message. Which of the following statements about qinq is false?

A.QinQMakeVLANincreased to4095*4095

B.basicQinQbased on the interface

C.flexibleQinQAccording to different inner layersTagwith different outer layersTag,correct to the userVLANThe division is more detailed

D.QinQtechnology enables private networksLANTransparent transmission on the public network

Question 127

IGP converges faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device can keep the OSPF and BGP linkage during the set linkage time.____The router makes the link metric value in the LSA advertised to be the maximum value, so as to inform other OSPF devices not to use this router to forward data, so as to avoid traffic loss. (Note: If English letters are involved, all uppercase)

Question 128

Senior engineers with rich experience can quickly solve faults only by experience, with high efficiency.

A.False

B.True

Question 129

What is the value of OSPF and BFD linkage?

A.The sending interval of BFD packets can reach the millisecond level, which is slower than the OSPF inductive link state

B.The hello sending interval of OSPF is at the second level, which is faster than BFD inductive link state

C.Through the BFD detected at the millisecond level, the OSPF status is associated to achieve the purpose of OSPF quickly inductive link state

D.Any change in the BFD status will not affect the OSPF neighbor status

Question 130

BGP/MPLS IP VPNs can only use LDP to construct public network tunnels.
