H3C Constructing H3C High-Performance Campus Networks Sample Questions:
1. The following statements about the role of BSR and RP in PIMSM are correct:
A) RP is a relay station for multicast sources to forward multicast traffic
B) BSR controls the collection and dissemination of RP information and is the management core of the PIM-SM domain
C) If there is no BSR in the PIM-SM domain, RP information cannot be diffused, multicast receivers cannot join normally, and multicast traffic cannot be forwarded normally
D) RP is the rendezvous point where multicast receivers join a multicast group
2. The following technologies belong to the link backup technology in the redundant backup technology.
A) RRPP
B) Link aggregation
C) Smart-Link
D) Dynamic routing
E) STP
3. The switch SWA and SWB are connected together by two optical fiber Gigabit Ethernet links. The switch SWA has the following interface configuration:
[SWA]interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1]gvrp
[SWA-GigabitEthernet1/0/1]port link-type trunk
[SWA-GigabitEthernet1/0/1]port trunk permit vlan 1 10
[SWA]interface GigabitEthernet 1/0/2
[SWA-GigabitEthernet1/0/2]port link-type trunk
[SWA-GigabitEthernet1/0/2]port trunk permit vlan 1 10
It can be seen from the above
A) Only by changing the configuration of GigabitEthe1/0/2 to be consistent with GigabitEthe1/0/1, can they join the same aggregation group
B) If SWA4 is switched to enable MSTP, one of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 will be blocked
C) If MSTP is enabled on the SWA switch, GigabitEthe1/0/1 and GigabitEthe1/0/2 can participate in forwarding
D) GigabitEthernet1/0/1 and GigabitEthe1/0/2 cannot join the same aggregation group
4. Routers running PIM-DM will periodically send Hello messages to discover neighbors, establish and maintain neighbor relationships. The following descriptions of Hello messages are correct. __
A) All PIM routers are members of the 224.0.0.13 multicast group
B) When the DR is elected, the router with the higher priority of the Hello message will become the DR
C) When the router runs IGMPV2, the DR is elected for the shared network segment through the PIMHello message, and the DR serves as the Querier of IGMP
D) The router sends PIM Hello in multicast mode, the destination address is 224.0.0.13
E) If Hello messages have the same priority, the router with the larger interface IP address will become the DR
5. GARP messages used in information exchange between GARP application entities are:
A) Empty
B) LeaveAll
C) JoinEmpty
D) Leave
E) LeaveEmpty
F) JoinIn
G) JoinAll
