What are two considerations when selecting the "best route" for a network device to reach its destination? (Choose two.)
The correct answer is B. metrics C. administrative distance. When a router selects the best route to a destination, it uses two primary criteria: (1) Administrative Distance (AD) - a value that ranks the trustworthiness of the routing source (e.g., static routes have AD 1, OSPF has AD 110, RIP has AD 120); the lower the AD, the more…

Explanation
When a router selects the best route to a destination, it uses two primary criteria: (1) Administrative Distance (AD) - a value that ranks the trustworthiness of the routing source (e.g., static routes have AD 1, OSPF has AD 110, RIP has AD 120); the lower the AD, the more preferred the route. (2) Metrics - values specific to each routing protocol that measure path cost (e.g., hop count for RIP, bandwidth/delay for EIGRP, cost for OSPF); the lower the metric, the better the path. MAC addresses (A) operate at Layer 2 and are not used in Layer 3 routing decisions. IP addresses (D) identify destinations but are not selection criteria. Subnet masks (E) help match routes but are not 'best route' selection factors.
