質問 3：
Which statements about reliability measurement are TRUE? (Multiple Choice)
A. The formula for calculating the MTTR is as follows: MTTR= Fault detection time + Hardware replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time A smaller MTTR indicates a higher reliability.
B. Generally, system reliability is determined by mean time between failure (MTBF) and mean time to repair (MTTR).
C. MTTR refers to the average time from the fault occurrence time to the fault recovery time.
D. MTBF refers to the average time (usually expressed in hours) from the fault occurrence time to the fault recovery time. A larger MTBF indicates a higher reliability.
正解：A,B,C

質問 5：
Which of the following statements are TRUE about communication between the active/standby ACs with servers in load balancing mode? (Multiple Choice)
A. The IP address of an AC does not need to be configured on the RADIUS/Portal server. The RADIUS/Portal server does not send COA/DM or Portal Logoff packets to the AC.
B. The IP address of an AC needs to be configured on the RADIUS/Portal server. The RADIUS/Portal server sends COA/DM or Portal Logoff packets to the AC.
C. The DHCP server adaptively associates with the relay agent of an AC, but does not automatically send DHCP request packets to the AC.
D. The DHCP server does not adaptively associate with the relay agent of an AC. It automatically sends DHCP request packets to the AC.
正解：B,C

質問 6：
Which of the following statements about the active CAPWAP link setup procedure are TRUE? (Multiple Choice)
A. In Discovery phase, after dual-link backup is enabled, an AP broadcasts a Discovery Request packet.
B. As long as the active and standby ACs work properly, they will return Discovery Response packets to the AP. The Discovery Response packets contain the dual-link backup flags, priorities, loads, and IP addresses of the ACs.
C. If the AC priorities are the same, the AP compares the loads of the ACs, that is, the number of APs. The AP selects the AC connecting to fewer APs as the active AC.
D. After receiving the Discovery Response packets, the AP selects an active AC based on AC priorities, loads, and IP addresses and sets up an active CAPWAP link with the active AC.
正解：B,D

質問 7：

What are the advantages of a WLAN Mesh network compared with the traditional WLAN? (Multiple Choice)
A. Reduce dependence on wired networks.
B. Increase signal coverage range.
C. Enhance signal strength.
D. The APs and ACs supporting Mesh have more functions.
正解：A,B

質問 9：
Which command is unnecessary for Mesh whitelist configuration?
A. mesh-whitelist-profile
B. radio radio-id
C. ap-system-profile
D. peer-ap mac
正解：C
