質問 1：
Which of the following statements about N+1 backup is TRUE?
A. N+1 backup is a cold backup mode, which backs up AP and STA information.
B. The active and standby ACs can be of different models but must use the same software version.
C. The models and software versions of the active and standby ACs must be the same.
D. A standby AC can provide backup services for multiple active ACs. This mode reduces device purchase costs and has higher reliability than VRRP HSB.
正解：B

質問 2：

A. Up to 100 Mbps
B. Up to 150 Mbps
C. Up to 50 Mbps
D. Up to 200 Mbps
正解：A

質問 3：
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. 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.
C. 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.
D. 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.
正解：C,D

質問 4：
The following is a description of the wrong description of the chain network in the Mesh network?
A. The link formed between the MPs can convert the 802.3 message into an 802.11s message and then transmit it on the wireless link.
B. In a chained network environment, there may be a single point of failure.
C. In a chained network environment, users cannot pre-assign neighbors connected to them.
D. In a chained network environment, users can pre-designate neighbors connected to them.
正解：C

A. [AC-wlan-view] rrm-profile name wlan-net
B. [AC-wlan-view] ap-system-profile name mesh-sys
C. [AC-wlan-view] wired-port-profile name wired-port
D. [AC-wlan-view] regulatory-domain-profile name domain1
正解：A

質問 8：
Which of the following statements is TRUE about communication between the active/standby ACs with the RADIUS/Portal server in load balancing mode?
A. If the original active AC is DOWN or the uplink of the original active AC is disconnected, the active AC needs to process received COA/DM packets and synchronize these packets to the standby AC, and delivers authorization information to APs.
B. The active AC fills the NAS IP address and accounting session ID into accounting and authentication packets.
C. If the original active AC is not DOWN or the uplink of the original active AC is not disconnected, a loopback interface that uses the same IP address as the active AC needs to be configured on the standby AC. Routes to the loopback interface are not advertised but imported to IGP.
D. The source IP address carried in RADIUS packets sent by the active and standby ACs must be the same, but the IP addresses of the two ACs configured on the RADIUS server carried in COA/DM packets can be different.
正解：B
