   A company has a pair of BIG-IP devices in an active/standby configuration. The virtual server is configured with a floating self-IP address. The active device experiences a hardware failure and the standby device takes over. Which statement best describes what happens to the floating IP address during this failover?

   • AThe standby device assumes ownership of the floating IP address and begins answering ARP requests for it.
   • BThe floating IP address remains with the failed device and is no longer reachable.
   • CThe floating IP address is automatically changed to a new address on the standby device.
   • DThe floating IP address is released and clients must use the standby device's management IP address.

   A company has a BIG-IP active/standby pair. The active device is experiencing intermittent hardware issues that cause it to reboot unexpectedly. The administrator wants to ensure that the standby device takes over quickly when the active device fails, but also wants to avoid unnecessary failovers during brief network blips. Which configuration approach best meets these requirements?

   • ADisable all failover triggers except for manual failover.
   • BEnable connection mirroring to ensure sessions are preserved during failover.
   • CSet the failover delay to 60 seconds to ensure no unnecessary failovers.
   • DConfigure a failover trigger for hardware failure and set the failover delay to a few seconds.

   A BIG-IP active/standby pair is configured with failover triggers based on hardware and network loss. The administrator wants to add a new trigger so that if the primary web server pool becomes completely unreachable from the active device, the standby device will take over. Which configuration change should the administrator make?

   • AConfigure a cron job on the active device to reboot the standby device every hour.
   • BSet the failover mode to 'forced' in the HA configuration.
   • CAssociate a health monitor with the virtual server and configure the monitor to mark the virtual server down, which initiates failover.
   • DEnable connection mirroring on the virtual server so the standby can take over the sessions.

   How do health monitors contribute to high availability?

   • AThey provide a virtual IP address for client access
   • BThey detect failures and trigger failover to the standby device
   • CThey balance traffic load between devices
   • DThey synchronize configuration between HA peers

   A company runs a mission-critical web application on a pair of BIG-IP devices in an active/standby configuration. The network team wants to ensure that when a failover occurs, clients can continue reaching the application without needing to update their browser bookmarks or DNS records. The application's virtual server is currently associated with a specific self-IP address on the active device. What should the administrator configure to meet this requirement?

   • AUse the active device's management IP address as the virtual server destination and rely on NAT for client traffic.
   • BAssign a floating self-IP address to the virtual server and enable it on both devices in the HA pair.
   • CCreate a new virtual server on the standby device with a different IP address and update DNS TTL to 30 seconds.
   • DConfigure a static route on the client's default gateway pointing to the standby device's management IP address.
