Huawei HCIP-Routing&Switching-IERS(Huawei Certified ICT Professional-Implementing Enterprise Routing and Switching Network) Sample Questions:
1. In the PIM-SM protocol, the DR connected to the multicast receiver is charge of sending a unicast Register message to the RP.
A) False
B) True
2. Using default routes between routers is a low-cost solution but requires more system resources than a complete routing table.
A) TRUE
B) FALSE
3. The following is the output information of the router RTA. Which of the following description of the output information is correctangle?
[RTA]multicast routing enable
[RTA]pim
[RTA-pim]static-rp 172.16.1.1
[RTA]interface Ethernet0/1
[RIA-Etheernet0/1]pim sm
A) PIM-DIM mode runs on the router
B) Statically specified RP is 172.16.1.1
C) The router runs multicast, you do not need to enable multicast routing-enable
D) Router RTA interface Ethernet0/1 runs PIM-DM
4. Regarding the two working modes of PIM-DM and PIM-SM, the correct description is: (Multiple Choice)
A) PIM-SM must require RP
B) PIM-SM is suitable for member-intensive multicast network structures.
C) PIM-SM works in a "push" mode of operation.
D) PIM-DM works in a "pull" mode of operation.
5. In multicast network environment, if IGMPv2 hosts and IGMPv1 routers (hereinafter referred to as version 2 host and version 1 router) are co-located on the same LAN, how do they work together?
A) When version 2 host leaves, it still sends an IGMP leave message, and the message can't be suppressed.
B) version 1 router treats the IGMPv2 report as an invalid IGMP message type and ignores it.
C) When Version 2 host detects that the IGMP Querier is Version 1 router, it must always respond with the IGMPv1 report.
D) When version 1 router is a valid IGMP querier, the version 2 host must send an IGMPv1 report.
