Your answer is incorrect.
Question 45 Not answered Answer – B Elastic Load Balancing automatically distributes incoming application traffic across multiple Amazon EC2 instances. It enables you to achieve fault tolerance in your applications, seamlessly providing the required amount of load balancing capacity needed to route application traffic. And the ELB is used to distribute traffic between instances in Multiple AZ’s. For more information on Elastic Load Balancer, please refer to the following link Some more key points about ELB: Elastic Load Balancer (ELB) is used for roting traffic to various EC2 instances located across the multiple Availability Zones(AZs). ELB can detect the healthy and unhealth EC2 instances. It will not route traffic to the unhealthy EC2 instances. If all the instances in the same AZ is not healthy, it will route the traffic to other AZ EC2 instances. Achieve higher levels of fault tolerance for your applications by using Elastic Load Balancing to automatically route traffic across multiple instances and multiple Availability Zones. Elastic Load Balancing ensures that only healthy Amazon EC2 instances receive traffic by detecting unhealthy instances and rerouting traffic across the remaining healthy instances. If all of your EC2 instances in one Availability Zone are unhealthy, and you have set up EC2 instances in multiple Availability Zones, Elastic Load Balancing will route traffic to your healthy EC2 instances in those other zones. The correct answer is: To evenly distribute traffic among multiple EC2 instances located in single or different Availability Zones.
