An application server cannot communicate with a newly installed database server. The database server, which has static IP information, is reading the following output from ipconfig:
IP: 10.0.10.240 -
Mask: 255.255.255.128 -
Gateway: 10.0.10.1 -
The application server is reading the following output from ipconfig:
IP: 10.0.10.25 -
Mask: 255.255.255.128 -
Gateway: 10.0.10.1 -
Which of the following MOST likely contains an error?
Both the database server and the application server are configured with IP addresses in what appears to be the same range, and they have the same subnet mask (255.255.255.128) and gateway (10.0.10.1). However, with a subnet mask of 255.255.255.128, the valid IP address range for the subnet is 10.0.10.0 to 10.0.10.127. The IP address of the database server, 10.0.10.240, is outside this valid range, which means it will not be able to communicate properly within the subnet. This indicates that an error was made in configuring the IP address of the database server. To resolve the issue, the IP address of the database server should be changed to a valid address within the subnet range, such as 10.0.10.2 to 10.0.10.126, considering the subnet mask of 255.255.255.128.
Another very poorly thought out question, it can be either the IP or the subnet mask. If you change the mask to /24 that also resolves the access issue. Answer is A because presumably they carved out this subnet for a reason but that should be explained in the question IMO.
A. IP address both the database server and the application server are configured with IP addresses in the same subnet (10.0.10.0/25) and the same subnet mask (255.255.255.128), and they have the same default gateway (10.0.10.1), which indicates they are on the same network segment. The issue is most likely related to the IP address configuration, as the database server has the IP address 10.0.10.240, while the application server has the IP address 10.0.10.25. Since the subnet mask is 255.255.255.128 (which corresponds to a subnet with addresses ranging from 10.0.10.0 to 10.0.10.127), the database server's IP address (10.0.10.240) is outside the valid range for the subnet. This suggests that there may have been a mistake in configuring the IP address of the database server. To resolve the issue, the database server's IP address should be corrected to a valid address within the subnet range, such as 10.0.10.2 to 10.0.10.126, considering the subnet mask of 255.255.255.128.
The database has IP: 10.0.10.240 - Mask: 255.255.255.128 - Gateway: 10.0.10.1 - This mask gives two subnets 10.0.10.0/25 and 10.0.10.128/25 so the ip address and the gateway are on different subnets. The Application Server is on IP: 10.0.10.25 - Mask: 255.255.255.128 - Gateway: 10.0.10.1 - The IP address and gateway are on the same subnet. So the answer is an incorrect IP address on the database server
