When running ifconfig command on an Appliance, there are interfaces shown in the list: eth1- Sync and eth2-Sync. What is the purpose of these interfaces?

Question

Options

• AThese interfaces are bond members (slaves) of Sync Bond
• BThese interfaces can be used as backup for Sync interface
• CThese interfaces are not in use, Security GW module use Sync interface for synchronization
• DThese interfaces represent physical Sync interface at the front panel of appliance

• A
  2% (1)
• B
  2% (1)
• C
  3% (2)
• D
  93% (55)

Explanation

On Check Point appliances, the -Sync suffix in the interface name (e.g., eth1-Sync, eth2-Sync) is how the operating system surfaces the physical sync ports located on the front panel of the hardware appliance - they are not logical constructs, but direct representations of dedicated hardware ports.

Why the distractors are wrong:

• A is incorrect because bond member/slave interfaces appear with bond notation (e.g., bond0, bond1) - sync interfaces are dedicated ports, not members of a bonded link.
• B is incorrect because these are not backup or failover paths for a primary sync interface; they are the sync interfaces themselves at the hardware level.
• C is incorrect and contradicts reality - these interfaces are in use; ClusterXL relies on the sync interface for state table synchronization between cluster members.

Memory tip: Think of the -Sync label as a name tag on a physical port - the appliance's OS is simply telling you "this ethernet port on the front panel is the sync port." If you can see it on the chassis, it shows up labeled -Sync in ifconfig.
