What is the Sync network on Appliances used for?

Question

Options

• AMay be used for any purpose, but synchronization always have priority
• BTo synchronize configurations and connections in between connection tables of different
• CTo transfer configuration files from Orchestrators to Appliances
• DTo transfer data in case of full utilization of the downlink interfaces

• A
  4% (1)
• B
  93% (25)
• C
  4% (1)

Explanation

Option B is correct because the Sync network on Appliances is specifically designed to synchronize state information - such as active connection tables and session data - between appliances operating in a high-availability or clustered setup, ensuring consistent network state across nodes.

Why the distractors are wrong:

• A is wrong because the Sync network is dedicated to synchronization; it is not a general-purpose interface that accepts other traffic, even with prioritization.
• C is wrong because configuration distribution from Orchestrators to Appliances occurs over the management or WAN fabric interfaces, not the Sync network.
• D is wrong because failover or overflow of data traffic uses WAN or LAN interfaces; the Sync network is not a data-plane fallback for saturated downlinks.

Memory tip: Think of the Sync network as a private "heartbeat and mirror" link - it only speaks the internal language of connection tables between peers, nothing else crosses it.
