質問 1:On the N+1 backup network, a total of 300 APs from AP1 to AP300 are deployed on AC1, and 400 APs from AP301 to AP700 are deployed on AC2. The AC can be configured as a standby AP. When the AP goes online, without changing the configuration, the following statement is wrong?
A. After the AC1 or AC2 fails to recover, the APs that go online in AC1 and AC2 are undefined.
B. If AC1 and AC2 are faulty at the same time, only the 500 APs from AP1 to AP500 can perform active/standby switchover in AC3, and the remaining 200 APs cannot go online in AC3. The services of these APs will be interrupted.
C. If the AC2 is faulty, the APs of the AP301 to the AP700 will perform the active/standby switchover in the AC3.
D. If the AC1 is faulty, the APs in the AP1 to AP300 will perform the active/standby switchover in the AC3.

質問 7:When configuring the connection between the Agile Controller and WLAN, we need to configure a port number if we want to enable Portal, as shown in the following configuration. The default port number is 2000.
What is the function of this port number? [AC] web-auth-server listening-port 2000
A. Number of the port that the WLAN device uses to receive Portal protocol packets
B. Source port number in the packets that the WLAN device sends to the Portal server
C. Number of the port that WLAN device uses to process Portal protocol packets
D. Destination port number in the packets that the WLAN device sends to the Portal server
正解:C
質問 8:Which of the following processing methods are TRUE, to solve the packet congestion on the tunnel?
(Multiple Choice)
A. The HAC discards broadcast or multicast ARP, ND, DHCP, and mDNS packets to prevent loops.
B. After broadcast/multicast packets are transparently transmitted to the FAC, the FAC converts the packets to unicast packets and forwards the packets over a specific tunnel based on the home AP connected to it.
C. The HAC at the tunnel ingress discards unknown unicast packets.
D. The FAP discards unknown unicast packets and forwards other packets to roaming STAs.
正解:B,C
質問 9:An enterprise needs to upgrade the AC. Which of the following methods is relatively secure to upload upgrade files to the AC?
