A user is accessing an EC2 instance on the SSH port for IP 10.20.30.40. Which one is a secure way to
configure that the instance can be accessed only from this IP?
Correct Answer:B
In AWS EC2, while configuring a security group, the user needs to specify the IP address in CIDR notation. The CIDR IP range 10.20.30.40/32 says it is for a single IP 10.20.30.40. If the user specifies the IP as 10.20.30.40 only, the security group will not accept and ask it in a CIRD format.

You have been given a scope to deploy some AWS infrastructure for a large orgAMsation. The requirements are that you will have a lot of EC2 instances but may need to add more when the average utilization of your Amazon EC2 fileet is high and conversely remove them when CPU utilization is low. Which AWS services would be best to use to accomplish this?
Correct Answer:C
Auto Scaling enables you to follow the demand curve for your applications closely, reducing the need to manually provision Amazon EC2 capacity in advance. For example, you can set a condition to add new Amazon EC2 instances in increments to the Auto Scaling group when the average utilization of your Amazon EC2 fileet is high; and similarly, you can set a condition to remove instances in the same increments when CPU utilization is low. If you have predictable load changes, you can set a schedule through Auto Scaling to plan your scaling actMties. You can use Amazon CIoudWatch to send alarms to trigger scaling actMties and Elastic Load Balancing to help distribute traffic to your instances within Auto Scaling groups. Auto Scaling enables you to run your Amazon EC2 fileet at optimal utilization. Reference: http://aws.amazon.com/autoscaIing/
