CV0-004 Question #76: Real Exam Question with Answer & Explanation

Question

A cloud engineer is troubleshooting a connectivity issue. The application server with IP 192.168.1.10 in one subnet is not connecting to the MySQL database server with IP 192.168.2.20 in a different subnet. The cloud engineer reviews the following information: Which of the following should the cloud engineer address to fix the communication issue?

Options

• AThe Application Server Stateful Firewall
• BThe Application Server Subnet Routing Table
• CThe MySQL Server Stateful Firewall
• DThe MySQL Server Subnet Routing Table

Explanation

{"question_number": 2, "explanation": "The application server (192.168.1.10) is initiating a connection to the MySQL server (192.168.2.20) on port 3306. Stateful firewalls track connection state and allow return traffic automatically for outbound-initiated sessions. The issue is that the MySQL server's stateful firewall is likely blocking inbound connection requests from the application subnet on port 3306. The routing tables would cause a 'no route to host' error, not a connection failure. The application server's firewall would block outbound traffic from itself, not inbound to MySQL. Fixing the MySQL server's stateful firewall to permit inbound traffic on port 3306 from 192.168.1.10 resolves the connectivity issue.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
