AD DS domain controllers are reachable by IP from a peered session-host VNet, but new hosts cannot resolve the domain during join. The host VNet still uses DNS that cannot resolve AD records. Which change addresses the stated defect?

Choose the single best answer.

A.Add a public IP to each host
B.Open the managed Shortpath listener
C.Increase the storage-account quota
D.Configure reachable DNS servers or forwarding that resolves the AD domain

Show the answer and explanation

✓ Correct answer

Configure reachable DNS servers or forwarding that resolves the AD domain

Peering supplies connectivity, not automatic AD DNS configuration. Set a supported resolver path and verify domain records from the host network. Option explanations: A. Add a public IP to each host: A public IP does not make AD DNS records resolvable. B. Open the managed Shortpath listener: The UDP display-transport listener does not supply directory DNS. C. Increase the storage-account quota: Profile capacity does not affect AD DNS resolution. D. Configure reachable DNS servers or forwarding that resolves the AD domain: Domain join requires domain-name resolution as well as IP reachability.
