   What is the main purpose of link aggregation (bonding)?

   • ATo encrypt data across a single network link
   • BTo replace the need for a network switch
   • CTo combine multiple physical links into a single logical link for increased bandwidth and redundancy

   What is the main benefit of NIC teaming?

   • AIt encrypts all network traffic from the host
   • BIt reduces the number of IP addresses needed on the host
   • CIt provides failover and load balancing by combining multiple network adapters
   • DIt allows the host to connect to multiple networks simultaneously

   How does load balancing contribute to fault tolerance in a network?

   • ABy encrypting traffic to prevent interception
   • BBy distributing traffic across multiple servers or paths so no single device is overwhelmed
   • CBy blocking all traffic from untrusted sources
   • DBy compressing data to reduce bandwidth usage

   A web application is hosted on three servers behind a load balancer. The load balancer distributes incoming HTTP requests across the servers. If one server fails, the load balancer should stop sending traffic to it and continue serving requests from the remaining servers. What feature of the load balancer provides this behavior?

   • ASession persistence (sticky sessions)
   • BLink aggregation on the load balancer
   • CHealth checks and automatic server removal
   • DFloating IP on the backend servers
