NEW QUESTION # 130
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:
Application Server Stateful Firewall
Which of the following should the cloud engineer address lo fix the communication issue?
- A. The MySQL Server Stateful Firewall
- B. The Application Server Subnet Routing Table
- C. The MySQL Server Subnet Routing Table
- D. The Application Server Stateful Firewall
Answer: A
Explanation:
The connectivity issue between the application server and the MySQL database server in different subnets is likely due to the MySQL Server Stateful Firewall's inbound rules. The application server has an IP of
192.168.1.10, but the MySQL server's inbound rules only permit IP 192.168.1.10/32 on port 3306. This rule allows only a single IP address (192.168.1.10) to communicate on port 3306, which is typical for MySQL.
However, if the application server's IP is not 192.168.1.10 or the application is trying to communicate on a different port, it would be blocked. To fix the communication issue, the cloud engineer should address the inbound rules on the MySQL Server Stateful Firewall to ensure that the application server's IP address and the required port are allowed. References: Based on the information provided in the question and general networking principles.
