問題文

An operator wants the next hop of an existing flow to stay put when the group of next hops changes. Which statement is correct?

選択肢

1. A hash that stays consistent keeps the change in the flow to next hop latency small when a next hop joins or leaves the group, that function pairs naturally with weighted spreading, where the impact of a change stays proportional to the cost of the given next hop, and the same fabric can spread traffic across a group of balancers when the prefix is advertised as anycast.
2. A hash that stays consistent keeps the change in the flow to next hop affinity small when a next hop joins or leaves the group, that function pairs naturally with weighted spreading, where the impact of a change stays proportional to the cost of the given next hop, and the same fabric can spread traffic across a group of balancers when the prefix is advertised as conditional.
