Refer to the exhibit. The image server and client A are running an application that transfers an extremely high volume of data between the two. An engineer is configuring a dedicated circuit between R

To ensure that *only* traffic for the Image Server (10.10.13.10) uses the new dedicated circuit, a host route with a `255.255.255.255` subnet mask is required. This specific route explicitly directs traffic for `10.10.13.10` towards the next-hop `10.10.10.6`, which is designated as the entry point to the new circuit from R1's perspective. A similar host route would also be needed for Client A to complete the setup.

Using a `/25` mask (`255.255.255.128`) creates a network route that covers a range of IP addresses, not just the specific host. This would force more traffic than just the Image Server's to use the new circuit, violating the 'only traffic between' requirement.

Using a `/30` mask (`255.255.255.252`) creates a network route that covers a range of IP addresses, not just the specific host. This would force more traffic than just the Image Server's to use the new circuit, violating the 'only traffic between' requirement.

While a host route (`255.255.255.255`) is correct for specificity, the specified next-hop `10.10.10.2` contradicts the implied correct next-hop `10.10.10.6` for the dedicated circuit, as indicated by the correct answer.
