AWS Certified Cloud Practitioner (CLF-C02) — Question 575

A company wants to log in securely to Linux Amazon EC2 instances.

How can the company accomplish this goal?

Answer options

• A. Use SSH keys.
• B. Use a VPN.
• C. Use end-to-end encryption.
• D. Use Amazon Route 53.

Correct answer: A

Explanation

Amazon EC2 utilizes SSH key pairs to securely authenticate and log into Linux instances, eliminating the need for password-based logins. While a VPN secures network pathways and end-to-end encryption protects data transmission, they do not serve as the direct login credential mechanism for instances. Amazon Route 53 is a DNS service and is not used to log into servers.
