H3CSE-RS-SW 認定 GB0-372-ENU 試験問題:

1. Concerning the comparison of BPDU processing methods between RSTP and STP, which of the following statements is correct? (Multiple choice)

A) In RSTP, a port in a blocked state can respond immediately when it receives a BPDU with priority.
B) After receiving the configuration BPDU, the RSTP switch calculates and compares the priority vector in the same way as STP.
C) The aging time of RSTBPDU is reduced from Max age to 3 consecutive Hello Time durations.
D) RSTP follows the STP configuration BPDU sending method. Configuration BPDU is only sent periodically by the root bridge.

2. The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1. The switch SWB has the following configuration information:
[SWB] rrpp domain 1
[SWB-rrpp-domain1] ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0 If switch SWA is the master node of primary ring 1, and if switch SWB port GigabitEthem2/0/1 fails, what can we learn from the above information? (Multiple choice)

A) If switch SWB finds that port GigabitEthernet 2/0/1 is Up again, it will immediately unblock the port.
B) The switch SWA immediately switches to the Failed state and releases the secondary port
C) The switch SWA will send a Common-Flush message to notify all transmission nodes
D) SWA will send a Link-Down message to notify all nodes

3. In the switching network shown in the figure, VLAN10 is set as lsolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as the secondary VLAN of VLAN 10; VLAN2 and VLAN20 are created on switch SWB, and VLAN20 is set as lsolate-user-vlan, and VLAN4 is set as the secondary VLAN of VLAN20. After setting the IP addresses of each device, check the MAC address table on SWA, and it will be displayed that PCB belongs to? (Multiple choice)

A) VLAN 10
B) VLAN 1
C) VLAN 4
D) VLAN 3
E) VLAN 20
F) VLAN 2

4. Contrast the calculation convergence of RSTP and STP. Which of the following statements is correct? (Multiple choice)

A) Compared with STP, STP defines a fast switch mechanism for designated ports, which allows the designated port to quickly enter the forwarding state without waiting for twice the Forward Delay time.
B) Compared with STP, STP defines a fast root port switching mechanism, which allows the Alternate to quickly become the new root port.
C) If STP wants to shorten the convergence time, it can only configure a smaller ForwardDelay time, but this may affect the stability of the network.
D) Compared with STP, RSTP defines edge ports, which can make the ports connected to the i machine quickly enter the forwarding state

5. In a certain network, it is planned to use an S5560 switch as a RADIUS client and two iMC servers as RADIUS servers to complete the user's secure authentication access. Which of the following statements is correct? (Multiple choice)

A) Two iMC servers cannot work in master-slave mode
B) When configuring the S5560, ensure that the device can communicate with the iMC server.
C) By default, the IP address of the RADIUS server on the S5560 is 192.168.1.1
D) If the two iMC servers can adopt the master-slave mode, then the two RADIUS server IP addresses configured on the S5560 must be the same
