Which system provides database synchronization to the passive node of an HA pair Grid Member?

Comprehensive and Detailed In-Depth Explanation:In an Infoblox High Availability (HA) pair, the active node maintains the live database and services (DNS, DHCP, etc.), while the passive node remains on standby, ready to take over if needed. Database synchronization between the active and passive nodes is handled directly by the active node using thebloxSyncmechanism over a secure connection (typically SSL). The Grid Master oversees Grid-wide synchronization, but within an HA pair, the active node is responsible for keeping the passive node’s database up-to-date. The Grid Master Candidate (GMC) and DNS Primary are unrelated to this specific HA pair sync process. This is a key troubleshooting point in the INE course.References:Infoblox NIOS Documentation – HA Configuration; INE Course Content: NIOS DDI Grid Troubleshooting.
