Q1: List the components required to build Amazon VPC?
Ans: Subnet, Internet Gateway, NAT Gateway, HW VPN Connection, Virtual Private Gateway, Customer
Gateway, Router, Peering Connection, VPC Endpoint for S3, Egress-only Internet Gateway.
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. Provided an Internet Gateway is configured in such a way that traffic bounded for EC2
instances running in other VPCs.
Q8: How can you monitor network traffic in your VPC?
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.,
