問題文
A research university is deploying addressing for a new instrument network that will never be reachable from the public internet but must interconnect with three partner campuses. The architect wants prefixes that are highly unlikely to collide with partner ranges. Which choice fits, and what property makes it fit?
選択肢
- The private ranges of the older address family, since the three defined blocks are large enough for the four campuses to plan subnets that never overlap between sites.
- The local unicast range for the newer address family, because the prefixes are generated to be globally unique with high probability while remaining outside global reachability.
- The shared address space reserved for carrier translation, because it is not globally routable and therefore cannot leak outward.
- The link-local range, because it requires no configuration.
