Question 101

As shown in the figure, PC1 and PC2 are hosts that belong to the same network segment, below about between PC1 and PC2 What are the correct descriptions of IPv6 neighbor states?

A.There are five possible neighbor states between PC1 and PC2: Incomplete, Reachable, and Stale , Delay, Probe

B.If the MAC address information of PC2 can be queried on PC1, the neighbor relationship may be Stale

C.If the MAC address information of PC2 can be queried on PC1, the neighbor relationship must be Reachable

D.If pc2's MAC address information can be queried on PC1, the neighbor relationship may be Probe

Question 102

The duplicate address detection feature for NDP in the following description is incorrect?

A.IPv6 duplicate address detection technology is similar to free ARP in IPv4

B.Duplicate address detection is implemented via RS and RA messages

C.IPv6 unicast address is called a tentative address after it is assigned to an interface and before it is detected by duplicate addresses

D.The interface needs to perform duplicate address detection before enabling any of the unicast IPv6 addresses

Question 103

In 0SPFv3 , Router-LSA is generated by each router, which describes the interface address and cost of each link of the router, and also includes the RouterlD of the neighbor router

A.True

B.False

Question 104

The following description of the link state protocol is plausible?

A.Slow convergence and low CPU utilization

B.Fast convergence and low CPU utilization

C.Fast convergence and high CPU utilization

D.CPU utilization is high and loops are easy to generate

Question 105

RTA is the source DR router, RTB is the RP router, and the multicast source sends multicast data to the RTA, but the PIM is not visible on the RTB Register the multicast source to which the message is registered, then the possible causes are ?

A.The multicast network dynamically elects the RP instead RTA failed RPF check for BSR

B.Multicast network statically configures RP, while RTA router does not statically configure RP

C.RTB to RTA has no unicast routing, causing the RTB to fail RPF checks for the source

D.The RP elected by RTA is not an RTB
