To improve reliability of the CAPWAP link between the AP and AC on a large WLAN, users can set a higher DSCP priority for CAPWAP management packets.
- A. FALSE
- B. TRUE
Correct Answer: B 🗳️
After setting up tunnels with the active and standby ACs, the AP sends Echo messages to monitor tunnel status. The Echo messages contain the active/standby status of the tunnels. When the AP detects that the primary tunnel fails, it sends an Echo Request message with the active flag to the standby AC. After receiving the Echo Request message, the standby AC becomes the active AC, and the AP sends STA data to this AC.
- A. FALSE
- B. TRUE
Correct Answer: B 🗳️
If three APs are deployed in a small conference room which can accommodate a maximum of 90 people, CAC can be configured on each AP to limit the number of associated STAs within 30 and hide its SSID when the number of associated STAs exceeds 30.
In this way, load balancing can be achieved among APs.
- A. FALSE
- B. TRUE
Correct Answer: B 🗳️
