| Option C | the cost to reach a network that is administratively set
|
| Option D | . a measure of the trustworthiness of a routing information source

| Correct Answer | d |
Explanation Reference: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094195.shtml Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative distance defines the reliability of a routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the help of an administrative distance value. Administrative distance is the first criterion that a router uses to determine which routing protocol to use if two protocols provide route information for the same destination. Administrative distance is a measure of the trustworthiness of the source of the routing information. The smaller the administrative distance value, the more reliable the protocol.
