QuestionQ56

Stateful Firewall and Screen Options

When a new session is established on the primary ScreenOS device, which two outcomes occur on the backup device?

Choose two
  • A Session information is sent in real time from the master to the backup over the HA link.
  • B Session update messages are bundled together and sent over every 10 seconds to the backup over the HA link.
  • C A session is created on the backup device with a timeout value of 8 times the default.
  • D A session is created on the backup device and is completely identical to that of the master's session.
Explanation

ScreenOS HA synchronizes a newly created session to the backup in real time over the HA link. The backup maintains the synchronized session with a timeout that is eight times the initial/default timeout on the primary, allowing session state to persist for failover; therefore, it is not completely identical to the primary session.
