200-301 Question #1627: Real Exam Question with Answer & Explanation

The correct answer is B: 101. OSPF routes are shown as [110/101] 110 = Administrative Distance (AD) for OSPF (not the metric) 101 = OSPF metric (also called cost) For 172.20.0.222, the best match is 172.20.0.0/22 [110/101] via ... There is also a 172.20.0.0/24 [110/100] ..., but no /24 exists in your table. R

Explanation

OSPF routes are shown as [110/101] 110 = Administrative Distance (AD) for OSPF (not the metric) 101 = OSPF metric (also called cost) For 172.20.0.222, the best match is 172.20.0.0/22 [110/101] via ... There is also a 172.20.0.0/24 [110/100] ..., but no /24 exists in your table. Routers can only use what's in their routing table. OSPF metrics are based on the sum of interface costs along the path. If a route shows [110/101], that means the calculated cost from this router to that network is 101. If another route to a similar network shows [110/100], that means the cost for that network is 100.
