(An administrator deploys an EC2 instance with the public IP address 54.18.127.233 into a newly created VPC in us-west-2. The EC2 instance must be accessible via ec2-public-54.18.127.233.us-west-2.compute.amazonaws.com from the internet. Which solution should be used?)

Show Suggested Answer Hide Answer
Suggested Answer: B

Comprehensive and Detailed Explanation From Exact Extract:

To make the EC2 instance accessible via a public DNS hostname like ec2-public-54.18.127.233.us-west-2.compute.amazonaws.com, the administrator must set the VPC attribute enableDnsHostnames to true. This enables the automatic assignment of public DNS hostnames to instances with public IP addresses in the VPC. The WGU Cloud Deployment and Operations Study Guide (Section 3.2, VPC Configuration) states, 'Setting enableDnsHostnames to true in the VPC configuration ensures that EC2 instances with public IPs receive a public DNS hostname (e.g., ec2-public-<ip>.<region>.compute.amazonaws.com), facilitating internet accessibility.' Resource tags, disabling DNS support, and resource-based names do not enable this functionality.</region></ip>

Why would anyone set enableDnsSupport to false? That seems odd.

Wait, can you really access it without DNS support?

I think A is important too, but not the main issue here.

B is the right choice, you need DNS hostnames enabled.

I’m a bit confused about the difference between DNS hostnames and DNS support. I think both might be relevant, but I’m leaning towards option B.

This question reminds me of a practice exam where we had to configure VPC settings for public access. I feel like option B is the right choice here.

I'm not entirely sure, but I remember something about DNS support needing to be enabled for public IPs to resolve correctly.

I think we need to enable DNS hostnames for the EC2 instance to be accessible via the public DNS name.
