On a WLAN, the HSB service sets up an HSB channel between two devices that back up each other, maintains the channel status, and backs up data. Which of the following can HSB back up in real time?
Comprehensive and Detailed Step-by-Step Explanation:
HSB (Hot Standby Backup) Service:
HSB is used on WLAN controllers to back up critical information in real time to a backup device, ensuring service continuity in case of failures.
Backed-Up Information:
CAPWAP Tunnel Information (A):Essential for maintaining connections between APs and controllers.
AP Entries (C):Information about connected APs is backed up.
User Data Information (D):Includes client authentication and session details.
Incorrect Option:
DHCP Address Information (B):Not part of HSB's responsibilities, as DHCP is handled separately.
