Explanation

IP Routing Failover & Next-Hop Selection

Option A (192.168.101.18) is correct because when the primary next hop (192.168.101.2) fails, the routing table selects the next available path based on administrative distance and metric, and 192.168.101.18 represents the next-best path (typically the second entry in a floating static route or ECMP configuration with the next lowest metric/distance).

• Option B (192.168.101.6) is incorrect because it has a higher metric or administrative distance than .18, placing it lower in preference order.
• Option C (192.168.101.10) is incorrect for the same reason - it ranks lower in the routing table hierarchy than .18.
• Option D (192.168.101.14) is incorrect as it represents an even lower-priority path, typically the last resort before .18.

Memory Tip: Think of next-hop failover like a numbered queue - when the first person (primary next hop) leaves, the next person in line with the lowest ticket number steps up. In routing, that means the path with the lowest metric or administrative distance among remaining entries becomes active next.
