NO.133 In order to prevent hackers from attacking user equipment or network through MAC address, the MAC address of untrusted users can be configured as black hole MAC address to filter out illegal MAC

NO.134 Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors.
The routing policy deployed between IBGP neighbors is invalid.

NO.135 Does the role of Link-LSA in OSPFv3 not include?

NO.136 From this picture, we can judge

NO.137 As shown in the figure, all routers run OSPF, because R3 is in the backbone area, so there is no type 3 LSA in the LSDB of R3.

NO.138 The deployment of port isolation technology in Ethernet can realize Layer 2 intercommunication and Layer 3 isolation, making the network more flexible.

NO.139 (Connection question) Please match the command with the realized function.

NO.140 The RR rules for advertising routes violate the IBGP split horizon rules, which may cause loops in the AS. Which routing attributes does RR use to prevent loops?

NO.141 Which of the following statements about IPSG is false?

NO.142 There is the concept of forwarding equivalence class FEC in MPLS, which of the following description is wrong? (Multiple choice)

NO.143 In the multi-level RR scenario, a large number of secondary RRs will be connected to the primary RR, which may lead to BGP of the primary RR. The routing table overflows, what method can be used to reduce the risk of overflowing the routing table of the advanced RR BGP?

NO.144 Which of the following information can the DHCP binding table contain? (Multiple choice)

NO.145 To ensure security, authentication can be configured in the OSPFV3 process area view.

NO.146 Configuring DHCP Snooping can be used to prevent imitators from attacking. Which of the following steps should be included in the configuration process? (Multiple choice)

NO.147 During the test phase of the cutover, the criteria to indicate that the test has been completed are:

NO.148 As shown in the figure, R1, R2, R3, and R4 are in the same MPLS domain, and LDP is used to allocate MPLS labels between devices. R4 is the FEC Egress LSR of 4.4.4.0/24. If you want to realize that when R1 accesses 4.4.4.0/24, R4 does not need to query the label table but can understand the forwarding priority of the data, then R3’s outgoing label for the FEC should be (). (Please fill in the Arabic numerals directly, without symbols)

NO.149 In the VLAN aggregation technology, multiple Sub-VLANs are used to isolate the wide recruitment area, and these Sub-VLANs are aggregated into a logical Super-VLAN. A company divides different departments into different Sub-VLANs because of the Sub-VLAN. VLAN not only includes physical connections, but also can establish a three-layer VLANIF interface, which can directly communicate with the external network on the three-layer.

NO.150 By default, LDP adjacencies will trigger the establishment of LSP based on the IP routing of the 32bit address.

NO.151 Which of the following operations may affect the normal operation of the customer network? (Multiple choice)

NO.152 Part of the configuration of R1 is as follows. Which of the following statement about IS-IS on R1 is correct? (Multiple choice)

NO.153 In the intra-domain MPLS VPN network, when a data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels. Which of the following description is wrong about the two layers of labels? (Multiple choice)
