Which is the administrative distance for a static route?

1. 0

2. 1

3. 90

4. 110

The correct answer is: 1

The administrative distance for a static route is 1. Administrative distance is a value that rates the trustworthiness of a routing information source. Static routes are considered highly reliable since they are manually configured by a network administrator, rather than learned through a dynamic routing protocol. As such, they are assigned a low administrative distance of 1, making them more preferred than routes learned from dynamic protocols, which have higher administrative distances. The priority given to static routes helps ensure that they will be used for routing decisions before other routes that have higher administrative distances. For example, routes learned through protocols like EIGRP or OSPF have higher administrative distances (generally 90 and 110, respectively), meaning static routes will take precedence when the routing table is constructed.
