Load balancing is a technique used to distribute incoming network traffic across a group of servers in order to optimize resource utilization, maximize throughput, and minimize response time.

DNS round-robin is a technique used to distribute traffic across multiple DNS servers, not load balancers.

Hardware load balancers are typically faster than software load balancers because they are dedicated devices that are designed specifically for load balancing.

Load balancing does not directly improve security. However, it can help to improve security by providing redundancy and by making it more difficult for attackers to target a single server.

First-come, first-served is not a common load balancing algorithm because it does not take into account the load on each server. This can lead to uneven distribution of traffic and poor performance.

Load balancing is the process of distributing traffic across multiple servers in order to optimize resource utilization, maximize throughput, and minimize response time.

Network load balancer is not a common type of load balancer. The other three options are all common types of load balancers.

Capacity is the term for the maximum number of concurrent connections that a load balancer can handle.

Availability is not a common metric for measuring the performance of a load balancer. The other three options are all common metrics for measuring the performance of a load balancer.

Server selection is the process of selecting a server to handle a particular request.

Random is not a common load balancing algorithm because it does not take into account the load on each server. This can lead to uneven distribution of traffic and poor performance.

Global load balancing is the process of distributing traffic across multiple data centers.

SDN load balancer is not a common type of global load balancer. The other three options are all common types of global load balancers.

Inter-region load balancing is the process of distributing traffic across multiple cloud regions.

SDN load balancer is not a common type of inter-region load balancer. The other three options are all common types of inter-region load balancers.
