Question 6 of 520

As shown in the figure, a certain park has deployed IPv6 for service testing, and there are 4 routers in the network. Run OSPFv3 to realize network interconnection.

Regarding the LSA generated by the OSPFv3 network, which of the following statements is wrong?

R1 itself will generate Router-LSA to describe device interface information, and will receive Router-LSA generated by R2 and R3 at the same time

There is a Network LSA generated by R3 in the LSDB of R1, indicating that R3 may be the DR of this link

R1 will receive the two Link-LSAs generated by R2, describing the two links information connected to The safer, easier way to help you pass any IT exams. 4 / 86 R2 respectively

As an ABR, R2 will generate Inter-Area-Prefix-LSA describing the IPv6 address prefix of Area 1, and advertise it to R1 and R3

Question 7 of 520

A network engineer outputs the following information when troubleshooting OSPF. Based on this, determine which reason causes the adjacency relationship to fail to be established normally?

Authentication password is not-consistent

Regional type is not-consistent

The interval for sending Hello messages is not-consistent

The IP address mask of the interface is not-consistent

Question 8 of 520

A router is running OSPF, and the output information is as shown in the figure. Which of the following statements is correct?

The type of the LSA is AS-externa1-LSA

The destination network described by this LSA is 10.0.23.0/24

The LSA in the figure is generated by this router

This device is ABR Answer: B

Question 9 of 520

When there are multiple redundant links in the IS-S network, multiple equal-cost routes may appear. Regarding equal-cost routes in an IS-IS network, which of the following descriptions is wrong?

When the number of equal-cost routes in the networking is greater than the number configured through commands, and the priorities of these routes are the same, the route with the higher System ID of the next hop device is preferred for load sharing.

If negative arbitration sharing is configured, the traffic will be evenly distributed to each link.

After the equal-cost routing priority is configured, when the IS-IS device forwards the traffic that reaches the destination network segment, it will not adopt the load sharing method, but will forward the traffic to the next-hop with the highest priority.

For each route in the equal-cost route, the priority can be specified, and the route with the higher priority will be preferred. The rest are used as backup routes.

Question 10 of 520

As shown in the figure, all routers run OSPF.

Which of the following statements is correct?

R2 generates Router LSA in both area 1 and area 0

R2 forwards the Router LSA generated by R3 to R1

R2 forwards the Router LSA generated by R1 to R3

R2 only generates Router LSA in area 0
