Q48 & 49

  1. Question 48. What Is A Placement Group In Ec2 ?

    Answer :

    AWS provides an option of creating a Placement Group in EC2 to logically group the instances within as single Availability Zone.

    We get the benefits of low network latency and high network throughput by using a Placement Group.

    Placement Group is a free option as of now. When we stop an instance, it will run in same Placement Group in restart at a later point of time.

    The biggest limitation of Placement Group is that we cannot add Instances from multiple availability zones to one Placement Group.

Question 46. What Are The Main Features Of Classic Load Balancer In Ec2 ? Answer : Some of the main features of Classic Load Balancer (CLB) in Amazon EC2 are as follows: Health Check:  Based on the result of Health Check, Classic Load Balancer can decide to route the traffic. If any instance has unhealthy results, CLB will not route the traffic to that instance. Security:  We can create security groups for CLB in Virtual Private Cloud (VPC). With these features, it is easy to implement secure load balancing within a network. High Availability:  With CLB, we can distribute traffic among EC2 instances in single or multiple Availability Zones. This helps in providing very high scale of availability for the incoming traffic. Sticky Sessions:  CLB also supports sticky session by using cookies. The sticky sessions make sure that the traffic from a user is always routed to the same instance so that user gets seamless experience. IPv6:  CLB also support Internet Protocol version 6.

Question 41. Explain What Happens When I Reboot An Ec2 Instance ? Answer : Rebooting an instance is like rebooting a PC. The hard disk isn’t affected. You don’t return to the image’s original state, but the contents of the hard disks are those before the reboot. Rebooting isn’t associated with billing. Billing starts when you instantiate an image and stops when you terminate it. Rebooting in between hasn’t any effect.
