Q2: How do you safeguard your EC2 instances running in a VPC? Ans: Security Groups can be used to protect your EC2 instances in a VPC. We can configure both INBOUND and OUTBOUND traffic in a Security Group which enables secured access to your EC2 instances. Security Group automatically denies any unauthorized access to your EC2 instances. Q3: In a VPC how many EC2 instances can you use? Ans: Initially you are limited to launch 20 EC2 Instances at one time. Maximum VPC size is 65,536 instances. Q4: Can you establish a peering connection to a VPC in a different REGION? Ans: Not possible. Peering Connection are available only between VPC in the same region. Q5: Can you connect your VPC with a VPC owned by another AWS account? Ans: Yes, Possible. Provided the owner of other VPCs accepts your connection. Q6: What are all the different connectivity options available for your VPC? Ans: Internet Gateway, Virtual Private Gateway, NAT, EndPoints, Peering Connections. Q7: Can a EC2 instance inside your VPC connect with the EC2 instance belonging to other VPCs? Ans: Yes, Possible.

Ans: It is possible using Amazon VPC Flow-Logs feature. Q9: Difference between Security Groups and ACLs in a VPC? Ans: A Security Group defines which traffic is allowed TO or FROM EC2 instance. Whereas ACL, controls at the SUBNET level, scrutinize the traffic TO or FROM a Subnet. Q10: Hon an EC2 instance in a VPC establish the connection with the internet? Ans: Using either a Public IP or an Elastic IP. Q11: Different types of Cloud Computing as per services? Ans: PAAS (Platform As A Service), IAAS (Infrastructure As A Service), SAAS (Software As A Service) Q12: What is Auto Scaling? Ans: Creating duplicate instances during heavy business hours. Scale-IN and Scale-OUT are two different statues of Scaling. Scale-IN: Reducing the instances. Scale-OUT: Increasing the instances by duplicating. Q13: What is AMI? Ans: AMI is defined as Amazon Machine Image. Basically it’s a template comprising software configuration part. For example, Operating System, DB Server, Application Server, etc.,
