What configuration options can an administrator use to resolve connectivity issues for a newly added PC in a FortiGate network?

Setting the end IP address in the IP pool configuration to a specific value, like 192.2.0.12, is a common way to ensure that an IP address is available for assignment to the newly added PC. This action effectively reserves the specified address within the IP pool range, which can resolve connectivity issues by ensuring that the specific IP address is allocated to the PC when it attempts to connect to the network.

Using an appropriate IP address can mitigate conflicts and ensure that the device gets a valid address that allows for proper routing and connectivity to the rest of the network. Proper configuration of the IP pool is essential in dynamic environments where devices may frequently connect and disconnect. Assigning a specific end IP that aligns with the network’s subnet and excluding any used addresses can greatly enhance connectivity reliability for new devices.

In contrast, options that focus on modifying the PC's default gateway or making changes to the existing IP pool entries may not directly address underlying connectivity or availability issues. Additionally, changing the type of the IP pool or removing entries could lead to broader complications in IP management, so focusing on the specific assignment of an IP address can be a more effective immediate resolution.
