H3CSE-RS-SW - GB0-372-ENU Exam Practice Test

A. Between the client and the device, the EAP message adopts the EAPOL encapsulation format

B. CHAP authentication is used between the server and the device

C. Only the device can actively trigger the authentication method

D. The server and the device use PEAP authentication

A. SB sets the IGMP protocol version

B. Enable multicast globally using the multicast routing-enable command

C. Configure the PIM protocol

D. Enter IGMP view

A. If the GigabitEthernet1/0/2 port is in the Down state, the GigabitEthernet 2/0/1 port will also be in the Down state.

B. If the GigabitEthernet1/0/1 port is in the Up state, the GigabitEthernet 2/0/1 port will also be in the Up state.

C. If the GigabitEthernet1/0/1 port is in the Down state, the GigabitEthernet 2/0/1 port will also be in the Down state.

D. If the GigabitEthernet1/0/2 port is in the Down state, the GigabitEthernet 2/0/1 port will also be in the Down state.

A. If there is still a receiver in the shared network segment under the interface where the upstream router receives the prune message, the receiver will send a group join message

B. As long as the DR has a receiver of multicast group G locally, the DR will periodically send a join message to the upstream.

C. Both PIMSM and PIM DM have pruning veto processes

D. When there are no receivers of multicast group G locally in the DR, the DR will send a prune message to the upstream router.

A. To prevent the registration suppression timer from timing out, the DR will send a Register message encapsulated with multicast data to the RP before the timer times out.

B. The DR router of the multicast source maintains a registration suppression timer. If the timer expires, the DR will unicast the multicast source registration message to the RP.

C. After receiving the registration stop message, DR will update the registration suppression timer and continue to send data in multicast mode.

D. After receiving the registration message from the DR, the RP sends a registration stop message and updates the local (S, G) and (*, G) entries.

A. SWB can communicate with SWA

B. SWB can communicate with PCB

C. None of the above answers are correct

D. SWB can communicate with PCC

E. SWB can communicate with PCA

A. In ARP proxy mode, ARP will be flooded after ARP Miss

B. In Layer 3 forwarding, there is no difference in packet encapsulation and forwarding between ARP proxy mode and ARP proxy mode.

C. In ARP proxy mode, the destination MAC of the message sent by the virtual machine is the gateway MAC

D. LEAF establishes ARP flood suppression table entries based on ARP packets and BGPEVPN routes.
In ARP proxy mode, ARP flood suppression table entries are used first to reply ARP packets.

A. Since SWA does not enable STP, service recovery needs to wait for the MAC address of SWC to age, which takes 300 seconds by default.

B. SWB's port EO/1 needs to wait for the default 30 seconds to enter the forwarding state, so the service recovery from PCB to PCA takes a total of 30 seconds by default.

C. SWA port EO/1 will not send TCN BPDU to SWC after link is interrupted

D. SWB's port EO/1 enters the Forwarding state, triggering a topology change process, which shortens the MAC address aging time. Therefore, the service recovery from PCB to PCA takes a total of 45 seconds by default.

A. Router RTB enables VRRPV3 protocol

B. Router RTB is the owner of the VRRP IP address

C. Router RTB enables VRRPV2 protocol

D. VRRP simple character authentication is enabled on router RTB
