field defense

Cutover target

Root description of the current network

risk assessment

NO.132 Regarding BGP/MPLS IPVPN data forwarding, which of the following description is wrong?

When data is transmitted on the BCP/MPLS IP VPN backbone network, it always carries two layers of labels

The inner label during data forwarding is assigned by MP-BGP

The outer label during data forwarding can be allocated by LDP

NO.133 Regarding multi-instance CE (Mlulti-VPN-Instance CE, MCE), which of the following descriptions is wrong?

existMCEdevice needs to be differentVPNCreate their own routing table and bind to the correct interface

connected to the sameMCEbut not oneVPNInstance users cannot access each other

haveMCEfunctional devices can be found inBGPIMPLS IP VPNAccess to multiple applicationsVPNExample, reduce the investment of user network equipment

MCEandPEThere must be multiple physical links betweenVPINIsolation between instances

NO.134 Which description is correct about the MPLS forwarding mechanism? (Multiple choice)

The system automatically assigns an ID to the upper-layer application that uses the tunnel, also known as Tunnel ID

When an IP packet enters the MRLS domain, the FIB table is the first to be checked

If the Tunnel ID value is not 0x0, enter the normal IP forwarding process

If the Tunnel ID value is 0x0, enter the MPLS forwarding process

_[200 300]_

NO.137 Which of the following statements about MUX VLAN are correct? (Multiple choice)

Separate VLAN can communicate with all VLANs in MUX VLAN

Each Separate VLAN must be bound to a Principal VLAN

Principal VLAN can communicate with all VLANs in MUX VLAI

NO.138 Network administrator A wants to use ACL to match specific routing entries. Which of the following routing entries will be matched by the ACL rules in the figure? (Multiple choice) acl number 2000 rule 10 permit source 10.0.0.0 0.0.6.0

10.0.1.0/24 :

10.0.0.0/24

10.0.0.1/32

10.0.2.0/24

NO.139 As shown in the figure, OSPF is deployed in a campus, and Area 1 is deployed as an NSSA area. By default, R2 will automatically generate a Type 7 LSA default route and flood it in the NSSA area.

TRUE

FALSE

NO.140 When OSPFv2 evolves to OSPFv3, the format and function of LSA are exactly the same, except that the network layer address in LSA changes from IPv4 to IPv6.

TRUE

FALSE

NO.142 Ethernet is a network that supports broadcasting, and once there is a loop in the network, this simple broadcasting mechanism can cause catastrophic consequences. Which of the following phenomena may be caused by loops

The device cannot log in remotely

pass throughPINGSerious packet loss during network test with command

CPUOccupancy exceeds70%

use on the deviceDISPLAY INTERFA, CEcommand to view interface statistics, it is found that the interface receives a large number of

NO.143 As shown in the figure, network administrator A on the R1 router, after modifying the Local Preference value of the routing entry sent to R2 through the routing policy, can control the path of traffic leaving AS100.

TRUE

FALSE

Outgoing interface

VLANID

IP address

NO.145 Which of the following tools cannot be used to match BGP routing entries?

Community Filter

Advanced ACL

Basic ACL

IP Prefix List

NO.146 OSPF is deployed in a campus to achieve network interworking, and OSPF is also enabled on the GEO/0/2 interface of R3. Area1 is deployed as an NSSA area, and the device addresses are shown in the figure. An engineer configures a static route on R3 to access the loopback interface address of R4, and imports the static route in the 0SPF process. At this point, in the Type5 LSA received by R1, the forwarding address (FA) is____. (Note: Please fill in the IP address without mask)

NO.147 After executing reset isis all, the IS-Is protocol process needs to be restarted and neighbors need to be re-established, and various IS-IS statistics will not be cleared.

TRUE

FALSE

NO.148 What check items can be set by IPSG?

MA, Caddress

Outgoing interface

VLANID

IPaddress

NO.149 Regarding the difference between NSR and NSF, which one is correct?

NSF does not need neighbor routers to complete

NSR must rely on neighboring routers to complete

NSF must rely on neighbor routers to complete

Both NSR and NSF need neighbor routers to complete

NO.150 After the cutover is completeD. it is generally necessary to check the following items?

Software version

physical topology

data flow

control plane entry

NO.151 According to this picture, what can we judge? (Multiple choice)

If the routing policy on AS_Path is not configured, then 3002:-4/128 must not originate from AS 65001

R1 does not have routes of 3002:.3/128 and 3002.-4/128

R1 has routes of 3002.-3/128 and 3002:.4/128

If the routing policy on AS_Pash is not configured, then 3002:4/28 must originate from AS 65001

NO.152 IGP converges faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device remains as a () router within the set linkage time, so that the link metric value in the advertised LSA is the maximum value, thereby telling other OSPF devices not to use this router to forward data, so as to avoid the loss of traffic. (Note: If English letters are involved, all capitals are required)
