   How does load balancing improve application scalability?

   • ABy reducing the number of application servers needed
   • BBy increasing the processing power of each individual server
   • CBy allowing multiple servers to handle traffic as a single logical unit
   • DBy storing all application data in a central database

   An organization runs a mission-critical application on a pair of BIG-IP devices in an active/standby configuration. The active device fails during a maintenance window. The standby device takes over, but the application becomes unreachable for several minutes. What is the most likely cause of the delay?

   • AThe standby device had to reboot to load the configuration before it could accept traffic.
   • BThe failover occurred, but the new active device had to relearn connection and persistence information, delaying traffic processing.
   • CThe standby device was not configured with a health monitor, so it did not know the servers were healthy.
   • DThe network team had to manually update the default gateway on the application servers to point to the new active device.

   What is the purpose of health monitoring in an ADC?

   • ATo periodically check the availability and performance of backend servers
   • BTo block malicious IP addresses
   • CTo encrypt traffic between clients and servers
   • DTo track user login credentials

   A company runs a stateful application on two servers behind a BIG-IP. They need to ensure high availability and performance. They have enabled persistence based on source IP. During a server failure, users who were connected to the failed server lose their session and must log in again. The company wants to minimize this disruption. Which action would be most effective?

   • AUse a load-balancing algorithm that distributes traffic evenly to avoid overloading a single server.
   • BEnable connection mirroring to replicate TCP connections to the standby device.
   • CConfigure a health monitor to detect the failed server and mark it down.
   • DEnable persistence mirroring on the BIG-IP so session state is replicated to the peer device.

   What is a key advantage of centralized management in an ADC?

   • AIt automatically fixes application bugs
   • BIt requires each application to have its own separate ADC
   • CIt eliminates the need for network monitoring
   • DIt allows administrators to apply consistent policies across multiple applications from a single point
