CompTIA Cloud+ (CV0-002) — Question 96

An administrator is creating new severs in a public cloud. The workflow creates and application group with three VMs: one web server, one application server and one database server. The three VMs are all accessible via SSH, but the websites shows a 503-error referring to a database issue.
Which of the following is the MOST likely cause of the error?

Answer options

• A. Misconfigured VLAN
• B. Misconfigured proxy
• C. Misconfigured firewall rule
• D. Misconfigure routing

Correct answer: D

Explanation

The 503 error suggests that the web server is unable to communicate with the database server, which is often due to routing issues that prevent proper data flow. While misconfigured VLANs, proxies, or firewall rules can also cause connectivity problems, they would typically lead to different types of errors, not specifically a database-related 503 error.
