A user has created a subnet in VPC and launched an EC2 instance within it. The user has not selected the option to assign the IP address while launching the instance. Which of the below mentioned statements is true with respect to this scenario?
A.
The instance will always have a public DNS attached to the instance by default
B.
The user can directly attach an elastic IP to the instance
C.
The instance will never launch if the public IP is not assigned
D.
The user would need to create an Internet gateway and then attach an elastic IP to the instance to connect from internet
Suggested Answer:D🗳️
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. A user can create a subnet with VPC and launch instances inside that subnet. When the user is launching an instance he needs to select an option which attaches a public IP to the instance. If the user has not selected the option to attach the public IP, then it will only have a private IP when launched. The user cannot connect to the instance from the internet. If the user wants an elastic IP to connect to the instance from the Internet, he should create an internet gateway and assign an elastic IP to instance.
Correct Answer: D
Please notice that option D shows that is necessary both EIP and IGW to connect FROM internet. That makes all the difference, since the connection source is external.
"If the user has not selected the option to attach the public IP, then it will only have a private IP when launched. The user cannot connect to the instance from the internet. If the user wants an elastic IP to connect to the instance from the Internet, he should create an internet gateway and assign an elastic IP to instance."
