NO.124 What is wrong about the description of RP in PIM-SM?

All members of the group and multicast sources sending multicast data to the group converge to a unique RP

The initial multicast stream of all groups in the shared tree is forwarded to the receiver through the RP

One RP can serve multiple multicast groups at the same time, and one multicast group can correspond to multiple RPs

RP can be responsible for the forwarding of several or all multicast groups, and there can be one RP in the network

NO.128 Cross-device link aggregation enables data stream transmission and mutual backup of stack member switches. However, because of the limited bandwidth of stack cables between stack devices, which of the following methods can improve forwarding efficiency?

Connect stack devices through stack cards

Enable stack multi-master check function

Configure stack system MAC address switching

Enable traffic local priority forwarding

NO.129 You need to configure policy routing on the router to specify that specific traffic is forwarded through an interface.
When using policy-based routing, which two types of most typical information can be used to forward traffic along a particular path?

TTL and source IP address of the packet

Source IP address and Layer 2 source address

Source IP address and specific protocols (such as FTP, HTTP, etc.)

Service type header and message length

NO.130 The OSPFv3 protocol is a separately developed protocol. It differs from OSPFv2 in that OSPFv3 is based on links rather than network segments. Which of the following statement is incorrect?

The two routers connected to the link can establish neighbor relationships even if their IPv6 address prefixes are different.

The two routers connected to the link can establish neighbor relationships even if no unicast IPv6 address is configured.

The routing information obtained by the OSPFv3 router from the neighbor uses the link-local address of the neighbor as the next hop of the forwarded packet.

All OSPFv3 interfaces use the Link-local address as the destination address of the packet except the virtual link.

NO.131 As shown in the figure, SWA and SWB run the RSTP protocol, and Cost of Path has not been modified to keep the default. Which of the following statements is correct?

GE 0/0/1 on SWB is an Alternative port

GE 0/0/2 on SWB is an Alternative port

GE 0/0/1 on SWA is the backup port

SWB will become the root bridge

NO.132 As shown in the figure, which of the following statement is correct? (Multiple Choice)

If the R2 Ethernet 0/0/1 interface is down, the R1 BFD session can quickly detect the fault and notify R1 to make the OSPF neighbor relationship down.

The OSPF status changes to FULL, which triggers the BFD session.

If the R2 Ethernet0/0/0 interface is down, the next hop of the route that R1 reaches 10.0.0.2 is changed to 10.0.21.2.

If the BFD function is disabled on R2, the BFD session on R1 will be down. This will result in the ospf neighbor relationship down.

If the R2 Ethernet 0/0/1 interface is down, the next hop of the route that R1 reaches 10.0.0.2 is changed to 10.0.12.2.

NO.133 When the ABR is NSSA region of the 5/7 type LSA when changing dedicated router, then the ABR can 7 classes LSA converted from 5 classes LSA polymerization.

True

False

NO.134 The IS-IS neighbor between R3 and R1 is not established. According to the information in this figure, what is the possible cause?

The System ID of R3 and R1 are duplicated

IS-Levels of R3 and R1 do not match

The circuit-type of the interconnection interface between R3 and R1 does not match

IH certification of R3 and R1 failed

NO.135 Which of the following statement about IPSG technology is correct?

The IPSG can perform binding table matching check on P packets that enter the interface and leave the interface.

On the Huawei router, you can configure the IPSG function on the Vlanif.

If an interface is configured as a DHCP snooping Trust HCP ACK, DHCP NAKHCP, and Offerf packets, other untrusted ports cannot receive these packets.

ip source check user-bind check-item command to configure based VLAN or interface IP packet checking items, the command have effect on the dynamic and static entries.

NO.136 What are the three ways to send IPv4 packets? (Multiple choice)

Broadcast

Unicast

Multicast

Anycast

NO.137 In an MPLS VPN network, when a data packet enters the public and is forwarded, it will be encapsulated with two layers of MPLS labels. Which of the following options describes the processing procedure of the data packet correctly? (Multiple Choice)

The outer label of the packet received by the penultimate hop device is 3

The Egress PE device receives untagged IP packets

The Egress PE device correctly sends the data packet to the corresponding VPN according to the inner label

The packet is forwarded to the Egress PE device after the outer label pops up on the penultimate hop device

NO.138 Regarding the description of the extended features of ISIS, which of the following is correct? (Multiple Choice)

If there are devices from other manufacturers on the network that do not support the LSP fragmentation function, the fragment extension mode must be configured to Mode-1, otherwise the devices of other manufacturers cannot recognize the packet.

When the amount of information in the link state protocol data message PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP fragments to carry more ISIS information.

After the router’s LSP fragment extension function is enabled, you can use this function without restarting the ISIS process.

ISIS can choose whether to perform authentication verification on the received SNP and LSP packets.

NO.139 HW users are transmitting a lot of files through TFTP.
What protocol does TFTP rely on for transmission?

IcmP and UDP

iP and TCP

UDP

NFS

FTP

NO.140 A router have received a community attribute of a No-Export of BGP routing, how does the router deal with the BGP routing?

Discard the route directly.

No longer communicate to other BGP routers.

Only advertise to IBGP neighbors.

properly advertise the route, but do not use the routing to forward data.

NO.141 The network administrator is going to use the 6to4 automatic tunnel to carry IPv6 data on the IPv4 network. The IPv4 address of the router interface is 138.14.85.210. So the corresponding tunnel address is 2001:8a0e:55d2:1:230:65ff:fe2:9a6

True

False

NO.142 You expect to deploy multicast video applications on your private, internal network. In order to achieve this goal, you need to use private multicast IP addresses in your network. So which range of IP addresses can be used?

239.0.0.0-239.255.255.255

241.0.0.0-241.255.255.255

224.0.0.0-224.255.255.255

240.0.0.0-240.255.255.255

226.0.0.0-226.255.255.255

NO.143 In the command aggregate ipv4-address {mask | mask-length} [ as-set | attribute-policy route-policy-name1 | detail-suppressed | origin-policy route-policy-name2 | suppress-policy route-policy-name3], multiple parameters can be used to influence the summary route and its results.
What is the correct description about this command? (Multiple Choice)

If the Suppress policy is configured, the aggregated route is generated. The if-match clause of the route-policy is used to select the detailed route to be suppressed. The detailed route matching the route-policy is still advertised to other BGP neighbors.

If the Origin-policy is configured, only the detailed routes matching the Route-policy can participate in the aggregation.

If Attribute-policy is configured, you can change the attributes of the aggregated route.

If As-set is configured, AS_ATH of the summary route contains AS path information of all specific routes to prevent routing loops.

NO.144 Which of the following description about multi-instance CE features is wrong?

Since the MCE device is already bound to the VPN, there is no need to bind the VPN on the PE connected to the MCE device.

The interface of the MCE device root media receiving the routing information base can determine the technical source of the routing information base and maintain it in the routing and forwarding table of the corresponding VP

The implementation principle of MCE is to create respective routing and forwarding tables for different VPNs on the MCE equipment and bind them to the corresponding interfaces.

Configure MCE to enable one CE to connect to multiple VPNs at the same time, which can achieve complete isolation of services between different VPN users and reduce the investment cost of network equipment.

NO.145 What is the main reason why RSTP converges faster than STP?

RSTP increases the type of port status

RSTP has less overhead

RSTP is not based on timer convergence

RSTP has a smaller timer
