IGMP SSM Mapping statically binds the multicast source to the multicast group, so that the group members of IGMPv1 and IGMPv2 can also access the SSM multicast network. Which of the following statements about IGMP SSM Mapping is false?

• If the IGMP SSM Mapping. function is not enabled, neither IGMPv1 nor IGMPv2 supports the deployment of multicast in SSM mode
• IGMP SSM Mapping does not process IGMPv3 report packets. In order to ensure that hosts running any version of IGMP on the same network segment can obtain SSM services, it is necessary to run IGMPV3 on the interface of the multicast router connected to the network segment where the member hosts are located.
• Statically configure the mapping rules of SSM addresses on the IGMP querier, and map the group join information in the IGMPv1 or IGMPv2 member report to the group leave information
• The address of the multicast group of SSM is 232.0.0.0~232.255.255.255

When DLDP detects the existence of a unidirectional link in the fiber, the default actions of Huawei equipment include:The DLDP state machine transitions to the Disable state; outputs Trap information; automatically sets the interface to the blocked state. ( confirmed)

• True
• false

The association between LDP and IGP means that IGP suppresses the advertisement of reachable routes to ensure that LDP and IGP cooperate to complete network convergence, so that IGP and LDP maintain the same path, minimize traffic loss, and improve the reliability of the entire network.

• True
• false

A bookstore provides a wired network for customers to study online, but one day it is found that some users cannot access the network. After inspection, it is found that the IP resource of the DHCP address pool isRunning out, which of the following is the best way to solve the problem at hand?

Which of the following descriptions is correct about the FTP protocol?

• existFTP In Passive mode, the client completes the control and dataInitialization of a TCP session
• existFTP In Active mode, the server side passes the command'PORT' to tell the client which port it expects to send data on
• FTP always uses one TCP session to transfer control information and data information
• FTP always uses TCP port 20 for data sessions and ICP port 21 for control sessions
• FTP always uses TCP port 21 for data sessions and TCP port 20 for control sessions

Which of the following descriptions is correct about the MPLS processing mode for TTL?

• in Pipe mode. When an IP packet passes through an MPLS network, at the ingress node, IP TTL minus 1 maps to MPLS TTL field.
• in the MPLS labelTTL, which has the same meaning as the TL field in the IP header. TTL can prevent routing loops in MPLS networks.
• In Unifor mode, when IP packets pass through the MPLS network, the TTL minus 1. MPLS The TTL field is a fixed value.
• in MPLS In VPI, if you want to hide the structure of the MPLS backbone network, you can use the IngUni on ress form mode.
