How does the passive member of a High Availability (HA) pair receive its database updates?
Options
Answer CExplanation
Comprehensive and Detailed In-Depth
In an HA pair, the passive node stays synchronized with the active node to ensure seamless failover. This synchronization uses bloxSync, a proprietary Infoblox protocol that securely transfers database updates (e.g., DNS records, DHCP leases) between the HA pair members over an SSL-encrypted connection. The active node, being the operational member, directly provides these updates to the passive node. The Grid Master handles Grid-wide sync, but within an HA pair, the active node is the source. Options A and B misrepresent the mechanism (it's not a traditional VPN), and Option D incorrectly attributes the sync to the Grid Master. This is a critical HA troubleshooting topic in the INE course.
