   A company has a BIG-IP active/standby pair. The virtual server is configured with a floating self-IP address. The administrator notices that after a failover, clients are unable to reach the virtual server, even though the standby device has taken over the floating IP. What is the most likely cause of this issue?

   • AThe health monitor on the pool is not configured.
   • BThe floating IP address is not configured on the virtual server.
   • CThe standby device's management IP address is not reachable.
   • DThe upstream router or switch has not updated its ARP cache to point to the standby device's MAC address.

   An organization deploys two BIG-IP devices in an active/active configuration to handle a high volume of inbound traffic. Both devices are actively load-balancing connections to the same pool of backend servers. The administrator notices that when a client establishes a connection through Device A and then a failover occurs, the session is lost even though Device B is still up. What is the most likely reason for this session loss?

   • AConnection and state mirroring is not enabled between the two devices.
   • BThe backend servers are not configured for persistence.
   • CThe floating IP address is only configured on Device A.
   • DConfiguration synchronization is set to manual mode.

   An administrator has just made several changes to the virtual server configuration on the active BIG-IP device in an HA pair. The administrator wants to ensure the standby device has the exact same configuration so that a failover will not result in a loss of service due to missing settings. What should the administrator do?

   • ACopy the configuration files from the active device to a USB drive and insert it into the standby device.
   • BReboot the standby device to force it to reload the configuration from the active device.
   • CRun a manual configuration synchronization from the active device to the standby device.
   • DWait for the automatic sync that occurs every 5 minutes by default.
