What command would you use to classify directly connected routes?

1. ip route connected

2. route add connected

3. no shutdown

4. enable connected

The correct answer is: no shutdown

The command used to classify directly connected routes is typically a configuration command associated with the routing protocol or interface and does not specifically relate to “enable connected.” When focusing on directly connected routes, the correct approach is to ensure the interface is active, which is indeed relevant to the command used to bring an interface up. However, classifying directly connected routes usually relies on the inherent nature of how routing works in IP networks. In IP networking, a route is considered directly connected if the interface on the router belongs to the subnet of that route. When you issue a command to activate an interface (like “no shutdown”), it allows the router to participate in routing for that directly connected network. As such, the directly connected routes will be automatically included in the routing table once that interface is operational. The other options listed do not correctly apply to the classification of directly connected routes. For instance, commands related to route addition or administrative states that are not specifically for activating an interface do not pertain directly to the classification of connected routes. Therefore, the command associated with enabling an interface aligns with making sure that connected routes are recognized and classified properly in the routing table.
