Question 470An Azure Arc server appears offline in management after a proxy change, but Windows services and local networking remain healthy. Why does the proposed solution address the underlying problem? Servicing stack, component store and package applicability problems can persist even when downloaded update content is replaced. Boot configuration errors occur before normal guest network policy processing, so inbound firewall edits cannot address the failure. Arc heartbeat and extension management depend on agent-to-service reachability separate from ordinary workload network activity. AD DS client discovery uses SRV records for specific services; resolving a bare domain A record is insufficient evidence of DC location. ExplanationCorrect Answer C:Arc heartbeat and extension management depend on agent-to-service reachability separate from ordinary workload network activity. The mechanism explains the corrective action: Inspect Azure Arc Connected Machine agent and required endpoint or proxy connectivity, then repair its supported connection configuration. The associated validation is: Check Azure Connected Machine Agent status and perform a supported connectivity test before confirming the resource is online.

Question 477An administrator accidentally deletes a departmental user, and its object remains recoverable through the enabled AD Recycle Bin. Which remediation specifically resolves the problem rather than a related symptom? Restore the deleted object from Active Directory Recycle Bin while retaining supported original attributes and group membership state. Run repadmin and domain controller diagnostics to locate the failing naming context, partner and directory replication error. Diagnose domain controller service health using dcdiag, DNS registration checks and replication status before editing unrelated client policy. Enter Directory Services Restore Mode and follow a supported AD DS backup or system-state recovery procedure for the required restore scope. ExplanationCorrect Answer A:Restore the deleted object from Active Directory Recycle Bin while retaining supported original attributes and group membership state. This resolves the observed failure because aD Recycle Bin preserves eligible deleted objects for restoration without a full directory database rollback within the configured retention window. A suitable acceptance check is: Recover the test user and verify object SID, group memberships and authentication while inspecting required restore rights. Other Answers B:Active Directory replication has topology and directory service dependencies beyond basic network ping connectivity. This failure calls for a decision to restore the deleted object from Active Directory Recycle Bin while retaining supported original attributes and group membership state.
