H3CSE-WLAN Sample Questions:
1. Regarding the local forwarding function of FIT APs, the following statements are correct:
A) After enabling the local forwarding function, the AP directly forwards the data of the client, and the AC does not participate in the data forwarding, which greatly reduces the burden of the AC
B) To realize the local forwarding function, a configuration file needs to be delivered to the AP. The function of this file is to configure the Ethernet interface type of the wired side of the AP as trunk type, and allow the management vlan and service vlan data to pass through.
C) The administrator can configure the local forwarding of the user data accessed from the specified SSID, but cannot configure the local forwarding of the user data accessed from the specified vlan
D) Currently all Fit APs support the local forwarding function
E) After the local forwarding function is enabled, the control flow and data flow are handled in different ways. The control flow of the management AP and users is handled by the AC, while the user data forwarding is directly handled by the AP.
2. The following models of wireless service boards that do not need to configure switch port aggregation are ( )
A) LSQM1WCMB0 (S7500E)
B) LSBM1WCM2A0 (S9500)
C) LS8M1WCM128A0 (S7500)
3. Which of the following operations is the easiest and most effective way to avoid interference in the AP working environment?
A) Replace AP Antenna
B) Adjust AP working channel
C) Restart the AP device
D) Adjust the VLAN attribute of the SSID
4. Which of the following methods can reduce signal interference?
A) Troubleshoot and eliminate sources of interference in the field environment, such as microwave ovens, Bluetooth, and cordless phones
B) Mixed deployment of 11a and 11g
C) Adjust the transmit power of some APs
D) Network optimization with non-overlapping channels
5. The description about hidden nodes is correct
A) cts-to-self is to solve the hidden node problem
B) In order to reduce the impact of hidden nodes in the indoor environment, the RTS/CTS function can be enabled on the AP side
C) The formation of hidden nodes between APs may result in collision and loss of packets sent by APs to STAs
D) In the outdoor AP+CPE environment, to reduce the impact of hidden nodes, the RTS/CTS function can be enabled on the AP side
