Question 111

Regarding the description of the permanent multicast address, the error is ?

A.All routers running the OSPF protocol listen to 224005

B.All hosts and routers in the network segment listen on 224001

C.All routers running the PIM protocol listen on 22400100

D.All routers listen on 224002

Question 112

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

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

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

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 113

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

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

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

D.The RP elected by RTA is not an RTB

Question 114

If you have a Huawei switch running the STP protocol, and now connect the GO/O/17 interface and the GO/O/18 interface of the switch through a cable, then the scenario described below is correct ?( Single choice questions).

A.Both the Go/0/17 interface and the G0/0/18 interface enter the Disccarding state

B.The GO/0/18 interface will continuously change back and forth between the Listening state and the Learning state

C.The Go/0/17 interface enters the Blocking state

D.GO/0/18 interface will enter the Disking state

E.Both the G0/0/17 interface and the GO/0/18 interface enter the Forwarding state

Question 115

When you deploy LLQ, you need to configure bandwidth parameters, what is the significance of bandwidth parameters?( Single choice questions).

A.It represents a reference CIR to calculate the burst size D of the built-in tactician token bucket Changing parameters is an option because LLQ always takes precedence over other queues

B.The parameter should be as small as possible. It means that the bandwidth is always preserved, and even if the LLQ is set, changing the parameters will reduce the available bandwidth of the interface

C.Provides a built-in policer to limit the maximum available bandwidth of a low-latency queue during congestion
