QUESTION: 203 The right answer is A To resolve the connectivity issue, let's analyze the configuration: The ISP provided a subnet of 98.174.235.142/28, which gives the following details: Network address: 98.174.235.128 Usable IP range: 98.174.235.129 to 98.174.235.142 Broadcast address: 98.174.235.143 The router is configured with a subnet mask of 255.255.255.224, which corresponds to a CIDR of /27. This subnet mask divides the provided range incorrectly. The /27 subnet would use addresses from 98.174.235.128 to 98.174.235.159, which is outside the range given to the company. The default gateway configured as 98.174.235.129 is actually a valid IP address within the provided /28 range but not valid with the /27 subnet mask. Evaluating the Options: Change the subnet mask to .240. This would imply a subnet mask of 255.255.255.240, or /28, which matches the ISP's provided range. This would be a valid option as it would align with the ISP's configuration. Change the Ethernet cable
