Answers
D.
Allocate an Elastic IP address and assign it to the instance
Suggested answer: D

Explanation:

The next step the administrator must take to access the Linux EC2 instance from the internet is:

D) Allocate an Elastic IP address and assign it to the instance.

Elastic IP (EIP) Requirement: By default, when an EC2 instance is launched in AWS, it receives a public IP address from Amazon's pool, which is not static. This IP address can change, for example, if the instance is stopped and started again. To have a static IP address, you need to allocate an Elastic IP (EIP), which is a persistent public IP address, and then associate it with the instance.

Public Accessibility: Without an Elastic IP, the instance may not be accessible over the internet after a reboot or stop/start sequence. Assigning an Elastic IP ensures the instance can be accessed consistently using the same IP address.
