Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 697 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 697
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A solutions architect creates a VPC that includes two public subnets and two private subnets. A corporate security mandate requires the solutions architect to launch all Amazon EC2 instances in a private subnet. However, when the solutions architect launches an EC2 instance that runs a web server on ports 80 and 443 in a private subnet, no external internet traffic can connect to the server.

What should the solutions architect do to resolve this issue?

  • A. Attach the EC2 instance to an Auto Scaling group in a private subnet. Ensure that the DNS record for the website resolves to the Auto Scaling group identifier.
  • B. Provision an internet-facing Application Load Balancer (ALB) in a public subnet. Add the EC2 instance to the target group that is associated with the ALEnsure that the DNS record for the website resolves to the ALB.
  • C. Launch a NAT gateway in a private subnet. Update the route table for the private subnets to add a default route to the NAT gateway. Attach a public Elastic IP address to the NAT gateway.
  • D. Ensure that the security group that is attached to the EC2 instance allows HTTP traffic on port 80 and HTTPS traffic on port 443. Ensure that the DNS record for the website resolves to the public IP address of the EC2 instance.

Selected Answer: B
Not A - Autoscaling Irrelevant B - ALB, route tales for the public subnet with a route to Priv subnet C - "NAT gateway" is "to allow [outbound] internet traffic", but this is about inbound traffic D - Instances are in the private subnet, therefore it wont work from the public.

Selected Answer: D
nsure that the security group attached to the EC2 instance allows inbound traffic on ports 80 and 443 from the desired sources (e.g., any IP or specific IP ranges). This allows external internet traffic to reach the web server running on the EC2 instance

NAT Gateway stays in public subnet, not in private subnet. So, C can't be.
