H3CSE-RS-SW Sample Questions:

1. The customer LAN switches SWA, SWB, SWC, and SWD form the RRPP ring main ring 1. Switch SWD is connected to switches SWB and SWC, but not to switch SWA.
The switch SWD has the following configuration information:
[SWD] rrpp domain 1
[SWD-rrpp-domain 1] 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 SWD port GigabitEtherent2/0/1 fails, what can we learn from the above information?

A) If the switch SWD finds that the port GigabitEthernet2/0/1 is Up again, it will immediately unblock the port.
B) SWA will send a Link-Down message to notify all nodes
C) The switch SWA immediately switches to the Failed state and releases the secondary port
D) The switch SWC immediately switches to the Failed state and releases the secondary port.

2. Regarding the description of Private VLAN technology and Super VLAN technology, which of the following is correct?

A) Super VLAN technology is also called VLAN aggregation. Its main purpose is to solve the problem of IP address waste or insufficient VLAN interface quantity.
B) Private VLAN is a Layer 2 VLAN technology, so switches that support Private VLAN technology are all Layer 2 switches.
C) Super VLAN is a three-layer VLAN technology, so the switches that support Super VLAN technology are all three-layer switches.

3. After executing the display interface Ethernet 1/0/2 command on the switch SWA, the output information is as follows:
[SWA] display interface Ethernet 1/0/2
Ethernet1/0/2 current state: UP
PVID: 10
Mdi type: auto
Link delay is 0 (sec)
Port link-type: trunk
VLAN passing: 1 (default vlan), 10
VLAN permitted: 1 (default vlan), 2-4094
Trunk port encapsulation: IEEE 802.1q
Port priority: 0
what can we learn from the above information? (Multiple choice)

A) The data frame with VLAN1 tag will not be stripped when it leaves port Ethernet1/0/2
B) The current switch has only VLAN1 and VLAN10.
C) Data frames with VLAN 20 tags will be discarded when they enter port Ethernet 1/0/2
D) Port Ethernet1/0/2 only allows data from VLAN 1 and VLAN 10 to pass through.

4. SSH uses a complete user authentication mechanism to ensure the legitimacy of the logged-in user. Which of the following descriptions of the SSH authentication method is incorrect? (Multiple choice)

A) If no authentication is used, the server will return verification success in any case
B) Password verification is an authentication method that must be supported
C) No authentication is an optional authentication method
D) During the password verification process, the server will check the legitimacy of the user's private key and password. If they are legitimate, the request will be accepted.

5. Which of the following multicast group management protocols can support the SSM model?
(Multiple choice)

A) IGMPV2
B) MLDvl
C) IGMPV3
D) MLDV2
E) IGMPvl
