Administrative Distance — Cisco CCNA (200-301) Practice Questions
Administrative distance is the trustworthiness value assigned to a routing information source, used by Cisco IOS to choose between routes learned from different protocols when multiple protocols advertise a path to the same destination. Lower administrative distance values indicate more trusted sources, so a directly connected route (AD 0) always wins over an OSPF route (AD 110) or a RIP route (AD 120). The CCNA 200-301 exam tests candidates on the default AD values for common sources and how floating static routes use a higher AD as a backup path.
