{"question_number": 10, "question": "A distributed application is under development... URL and port: devasc468262987.com port 443 The requests... could not execute because the application was blocked by the firewall...", "correct_answer": "C", "explanation": "Port 443 is the well-known port assigned to HTTPS (HTTP Secure), which is HTTP traffic encrypted using TLS/SSL. The firewall must allow HTTPS traffic on port 443 for the application to communicate with the API server. SSH (A) uses port 22. HTTP (B) uses port 80, not 443. FTP (D) uses ports 20 and 21. Since the URL uses a standard domain name and port 443, HTTPS is the protocol in use, and it must be explicitly permitted by the firewall rule.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
