NO.13 The following is the correct description of the aggregation of BGP (radio).

After you configure the Aggregate ipv4-address mask, only aggregate routes are published, not detail routes.

For IPv6 routing, BGP supports manual aggregation and automatic aggregation.

BGP enables automatic aggregation by default.

Routes in the BGP local route table can be manually aggregated.

NO.14 When the load is an ICMPv6 message, what is the numeric value of the Next Header field in the IPv6 header if the presence of an extended header is not taken into account?

NO.15 The correct description of the scene shown in the following figure is:

LSDB

R1, which exists in both Level-1 and Leve-2, can ping the interface address of R2 loopback0

R there is a route to R2 loopback0 100

No neighbor relationship can be established between R1 and R2

NO.16 What is the following correct for the process of registering the source-side DR with RP in PIM-SM?

Encapsulated in the registered message is multicast service data

RP sends a registration stop message as soon as it receives the registration message.

Registered messages are used to build the RPT tree between source DR and RP

Registered packets are multicast packets.

NO.17 Why is BGP an enhanced distance vector routing protocol?

According to the routing rules of BGP routing, the route with lower MED is preferred

BGP uses the ASPATH attribute to record all autonomous system numbers that a route passes through into an AS list, and based on that attribute, routes with shorter AS-PATH are preferred

NEXT_HOP is a recognized mandatory attribute

BGP cannot accept routes that carry a local AS number in the AS_PATH

NO.18 There is no routing protocol running on the router HW and only one default route reaches the remote network.
On the router job with the extension Ping remote file server address 105401. The result of Ping on the router job is presented as “Request time.” out”? Based on the above description, the error in the following analysis is
?

Router HW’s next hop router does not have a path to the destination address

Ping is successful, but congestion occurs on the path to the destination address

ICMP packets can reach the destination address But the destination device failed to reply

Router HW does not have a legitimate route to the destination address

There is a firewall in the remote destination network, and no ICMP traffic is allowed

NO.19 The following statement about isis a route leak of ISIS is correct?

Route leaks for ISIS must be deployed on Level-1 routers

Route disclosure for ISIS is turned on by default.

Route disclosure for ISIS avoids suboptimal paths.

Route leaks for ISIS can only be applied to IPv4 environments.

NO.22 The message types of ISIS mainly include SNP, IIH, and LSP

True

False

NO.23 In a shared network, what mechanism does PIM-SM use to prevent duplicate traffic?( Single choice questions).

BSR/RP mechanism

Assert mechanism

Join/Prune mechanism

NO.24 Which IPV6 address would you ping to confirm that OSPFv3 is capable of pastoring unicast messages over the link?

Site local Multicast

Anycast Address

Global Address of the link

Unique Local Add

Link Local Address

NO.25 MACsec provides users with secure MAC layer data sending and receiving services. Which of the following is not a service available by ACsec?

User data encryption

Data source authenticity verification

Integrity check

Controllability check

NO.26 In order to configure M4, you first need to define a RADIUS server, which is defined as follows:
Huawei]radius-server template EXAM

False

NO.27 QinQ technology is a technology that extends the VLAN space by adding a layer of 8021Q tag messages to the extended VLAN. The function of space, the following statement about QInQ is mispronounced?

basic QinQ is implemented based on the interface orientation

QinQ increases the number of VLANs to 4095*4095

Flexible QinQ can be based on different inner layerS Tag and different outer layers of Tag, for user VL The division of AN is more granular

QinQ technology enables private VLANs to pass through the public Network
