Which of the following actions may affect the normal operation of the customer's network?

Regarding the BGPI MPLS IPVPN network architecture, which of the following descriptions is wrong?

As shown below:

In what ways can log information be viewed:

Please pair the following DHCP attack types with corresponding explanations.

In OSPFv3, an LSA whose propagation range is one area has_____kind. (Fill in Arabic numerals only)

BGP routing policies can control the advertisement and reception of routes.

The link status information between different S.4S processes of the routers around the Taiwan and Taiwan is considered to be sound insulation.

Configuring DHCP Snooping can be used to prevent imitator attacks, so the configuration process needs to include the following

What are the steps?

The correct description for the configuration on this switch is: 

[Huawei]dhcp enable

[Huawei]interface Vlanif 100 [Huawei-Vlanif 100]dhcp select relay

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)

As shown in the figure, on the R1 router, network administrator A sends the routing entry to R2 through the routing policy

After modifying the Local Preference value, you can control the path of traffic leaving the AS100

As shown in the figure, on the R1 router, network administrator A sends the routing entry to R2 through the routing policy

After modifying the MED value, you can control the path of traffic entering the AS100

From this figure, we can conclude that

The router ID of OSPF V3 needs to be configured in dotted decimal with a length of 128 bits.

In BGP/MPLS IP VPN, the 0SPF multi-instance process uses the DN bit to prevent Type5 LSA loops.

As shown below:

When configuring the DHCP Relay function on the device, the VLAN ANIF interface of the relay connection client must be bound with a DHCP server group, and the IP address of the proxy DHCP server must be configured in the bound DHCP server group.

The partial configuration of R1 is as follows. Which statement about OSPF on R1 is correct?

network 10.1.12.1 0.0.0.0

network 10.1.13.1 OQO.O

What is the LSA whose flooding range is the entire autonomous system in SPFV3?

As shown in the figure, in a medium-sized network, BGP generally deploys dual RRs to improve R reliability. When deploying dual RRs, the Cluster IDs of the two RRs are generally set to be the same. The reason for this is

After the cutover acceptance is complete

A campus has deployed IPv6 for service testing. There are 4 routers (R1, 22, R3 and R4) in this network, running 0SPFV3 to realize the interconnection of IPv6 network. A new router R5 needs to be connected to the network for testing. An engineer introduces a direct route in the OSPFVV3 process of R4 so that devices in the campus network can access the GE0/0/1 port address of R5. Which of the following statements about the scene is true of?

In OSPF, the A, BR will convert all type 7 L SAs in the NSSA area to type 5 L SAs.
