Q48. ISIS does not send CSNP packets under the P2P network type during the neighbor establishment process.

True

False

Q49. The following description of the characteristics of multi-instance CE is ?

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 MCE device can determine the source of the routing information according to the interface that receives the routing information, and maintain it in the route forwarding table of the corresponding VP.

MCE is implemented by creating their own routing forwarding tables for different VPNs on the MCE device and binding to the corresponding interface o

Configuring MCE enables a CE to connect to multiple VPNs at the same time, which can not only completely isolate the service between different VPN users, but also reduce the input cost of network equipment.

Q50. The following description of CBWFQ is correct?

CBwFQ can be configured with MQC and service-policy is applied to the exit direction

CBwFQ can be used for both egress and inbound interfaces

CBwFQ is delayed, jittered and bandwidth guaranteed for traffic catch

CBWFQ can only be configured in hierarchical policies-maps. The parent policy-map performs supervision and the child policy-map performs

Q51. A router Router LSA is shown in the figure below, and the following statement is incorrect?

This router is a DR

This router has established an adjacency relationship

This router supports external route ingestion

The Router ID of this router is 1001

Q52. Regarding MP-BGP, the following description is wrong?

Radio MP-BGP needs to assign a private label to the VPNv4 route

PE and CE are routed through BGP interaction, you need to create a BGP process on ce for each VPN instance

The message type and VPNv4 routing publishing policy for MP-BGP are the same as for BGP-4

MP-BGP advertises VPNv4 through two attributes, MP_REACH_NLRI and MP_UNREACH_NLRI Route

Q53. Man-in-the-middle attacks or IP/MAC spoofing attacks can lead to information leakage and other hazards, and are more common in the intranet, in order to prevent man-in-the-middle attacks or IP/MAC spoofing attacks, you can take the configuration method

Enable DHCP snooping to check the chaddr field in a DHCP request message

Configure the trusted/untrusted interface

Configure DHCP snooping on the switch to interbolde with DAI or IPSG

Limit the maximum number of MAC addresses allowed to be learned on the switch interface

Q54. Regarding the WRR (Weight Round Robin) description of the error is ?( Multiple select).

WRR avoids congestion in the network

WRR guarantees that various queues are allocated to a certain amount of bandwidth

WRR is a congestion management technique

WRR can no longer use

WRR on GE interfaces to ensure that critical services are prioritized for

Q55. There is a new HW office that needs to use their router as a DHCP server. When configuring the DHCP server to provide DHCP services to the current office, what of the following items need to be configured?

Exclude unused IP addresses from the DHCP server

Configure the timeout period for ping packets

Configure the startup file for the DHCP server

Configure manual binding

Configure dhcp address pool

Q56. What are the characteristics of Syslog information?

The transmission of Syslog messages is not secure

The transmission of Sysiog messages is reliable

The transmission of Syslog messages is confirmable

The transmission of Syslog messages is secure

The transmission of Syslog messages is not acknowledgable

The transmission of Syslog messages is unreliable

Q57. What are the types of link types included in OSPF’s route LSA?

Stubnet

P-2-P

VLINK

Fransnet

Q58. Unlike STP, RSTP has only one BPDU type, its value is 2, and there is no TCN BPDU.

TRUE

FALSE

Q59. In a network, the same gigabit running S and OSPF anti-tampering and fluttering as shown in the figure, on the two border routers RTB and RTC are introduced into the wine route, the device question is to use gigabit one port strobe, , 222 The network is introduced into the OSE via impotrote direct on the RTD, assuming that all other configurations are dead default configurations, then the description of this network is wrong ?

Adjusting the ISIS priority to 160 on the RTB avoids suboptimal routing problems in the network.

On the RTC, the following configuration is adopted, only the routes of the 2222/32 cinder segment can be filtered out when routing is introduced, IRTClip ip-prefix 10 index 1 deny2000 8 less-equal 32

RTB learns that the routing next hop for the 2/32 network segment is RTA

The following configuration can filter out the routes of the 2/32 CIDR block of the white RTD when RTC introduces OSPF routes.

Q60. As shown in the following topology, EBGP is running between ASI0O0, AS.203, AS.30, AS8400, and the neighbor relationship has been established as RECEIVed by AS4O0 When AS1OO issues a 1..11/2 CIDR segment BGP route, the path order recorded in the ASPath attribute is correct

10,200,3

400,300,200,100

100,200,300,400

300,200,100

Q61. After configuring the VLAN-based MAC address drift detection function, if the MAC address drifts, you can configure the actions of the interface according to your needs. Which of the following is not a configurable action?

Send an alert

The MAC address blocks

Interface blocking

Traffic filtering

Q62. Dual-bucket, two-speed is used in traffic governance, where the number of tokens in a C bucket is TC and the number of tokens in a P bucket is TP. When a message of length B enters, which of the following sentences is correctly described? (Multiple choice questions).

If TP-B~O and TC-B < 0, the message is marked green

If TP-B<0 and TC-B-0, the message is marked in red

If TP-B>0 and TC-B < 0, the message is marked yellow

If TP-B >O and TC-B > 0, the message is marked as a green

Q63. The command to adjust the LINK cost value for the IS-IS interface is ?( Radio)

ISIS cost

ISIS timer hello

lSIS circuit type

ISIS circuit level

Q64. After BGP introduces routes for other protocols, the next hop in the BGP routing table is consistent with the next hop of the introduced routing protocol

True

False

Q65. The duplicate address detection feature for NDP in the following description is incorrect?

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

Duplicate address detection is implemented via RS and RA messages

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

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

Q66. Configure the ipv6 preference under the IS-IS protocol view, the role of this command is to configure the priority of the Ipv6 protocol generated by the IS-IS protocol

TRUE

FALSE
