ルーター R1 で設定した場合、これらの要件を満たすコマンドはどれですか?(2 つ選択してください。)ネットワーク 2001:db8:2::/64 全体宛てのパケットは、ルーター R2 を経由して転送する必要があります。
ホスト2001:db8:23::14宛てのパケットは、できればR3を経由して転送する必要があります。
正解:D,E
Use D and E for this item. The route for the broader IPv6 network points traffic through R2, while a more specific or preferred host route can influence traffic for the individual host. Routers use longest-prefix match first, and administrative distance can make a route backup or less preferred when prefix length is equal. In Cisco CCNA 200-301 v1.1, IP Connectivity questions frequently test the practical boundary between similar features: what the feature does, where it is configured, and what problem it is meant to solve. The correct commands satisfy the network-wide path and the preferred host-specific path described in the exhibit. A clean way to validate the answer is to map the wording of the scenario to the actual device function. If the feature supplies addressing, forwarding, authentication, trunking, route selection, or controller communication, the answer must match that function exactly rather than a nearby protocol name.
