問題文
A team finds that clients using the newer address family cannot reach an internal service, while clients using the older family reach it. The service has records for both families. What is the most likely cause?
選択肢
- The clients' resolvers are misconfigured, since they should prefer the older family and a resolver that reverses that order breaks the reach.
- The service is not listening on the newer family, which means the records for that family should be removed so that clients fall back to the older family immediately instead of resolving an address the service cannot answer on.
- The newer family's path or filtering is incomplete, because the clients resolve the newer record and then have nowhere to go.
- The service certificate does not cover the newer family's address, and clients on that family abandon the session while they are still validating it.
