Review a compact Microsoft AZ-802 Windows Server Hybrid Administrator cheat sheet for hybrid identity, Azure Arc, migration, networking, storage, security, recovery, monitoring, and IT Mastery practice.
Use this AZ-802 cheat sheet before the free diagnostic or between timed sets. The goal is to keep Windows Server hybrid-administration decisions clear: preserve identity boundaries, onboard servers deliberately, validate network and storage dependencies, secure management paths, test recovery, and use Azure operations tooling without losing sight of on-premises reality.
Use this with practice. Review the hybrid checkpoints, then return to the AZ-802 page for the free 50-question diagnostic, public samples, timed mocks, topic drills, and the full IT Mastery bank.

| Area | What to know | Common trap |
|---|---|---|
| AD DS in hybrid environments | domain controllers, sites, replication, DNS, FSMO roles, trusts, authentication, and Microsoft Entra integration boundaries | replacing a domain or forest when the scenario requires preserving names, SIDs, and joins |
| Windows Server and hybrid workloads | Azure Arc, Windows Admin Center, server inventory, update management, policy, remote administration, and delegated access | assuming Azure management works before onboarding, agents, permissions, and connectivity are valid |
| VMs and containers | Hyper-V, Azure VMs, containers, image lifecycle, host placement, and workload isolation | treating containers, VMs, and physical servers as interchangeable deployment targets |
| Hybrid networking | DNS, routing, VPN/ExpressRoute concepts, name resolution, firewall paths, subnet design, and connectivity tests | troubleshooting the app before proving name resolution, ports, routes, and authentication paths |
| Storage and file services | SMB, DFS, Storage Spaces Direct, Azure File Sync, quotas, permissions, and storage migration | moving files without preserving ACLs, namespaces, sync scope, and cutover requirements |
| Security | privileged access, JEA/JIT concepts, administrative boundaries, patching, endpoint protection, certificates, and audit trails | using broad admin accounts because the environment is hybrid |
| High availability and recovery | clustering, load distribution, backup, site recovery, failover, restore testing, RPO/RTO, and runbooks | confusing data backup with service recovery |
| Migration | assessment, dependency mapping, replication, validation, cutover, rollback, and post-migration monitoring | starting migration before discovering identity, storage, DNS, and application dependencies |
| Monitoring and troubleshooting | Event Viewer, performance counters, Azure Monitor, logs, alerts, baselines, and health checks | reading one alert as root cause without correlating evidence |
| Distinction | How to decide in questions |
|---|---|
| Hybrid management vs cloud migration | Hybrid management keeps mixed environments visible and governed; migration moves workloads or data to a new platform. |
| Azure Arc vs Azure VM | Azure Arc manages non-Azure or on-premises servers through Azure control-plane features; Azure VMs run as Azure compute resources. |
| DNS issue vs authentication issue | DNS failures prevent reaching the right endpoint; authentication failures happen after the endpoint is found but identity, trust, or policy blocks access. |
| Backup vs disaster recovery | Backup restores data; disaster recovery restores a service within a time and data-loss objective. |
| High availability vs disaster recovery | High availability handles local component failure; disaster recovery handles broader outage or site-level disruption. |
| Migration assessment vs cutover | Assessment discovers readiness and dependencies; cutover changes production traffic or ownership. |
| Monitoring vs troubleshooting | Monitoring detects and alerts; troubleshooting isolates evidence, tests hypotheses, and confirms remediation. |
| Identity sync vs authorization | Sync makes identities available; authorization decides what those identities can do. |
AZ-802 questions often include small operational clues. Use the clue to decide whether the next action is identity, connectivity, storage, migration, recovery, or monitoring.
Get-ADReplicationFailure -Scope Site -Target "Toronto"
dcdiag /test:dns /v
Replication and DNS checks point to domain-controller health, site design, and name-resolution dependencies. Do not jump to workload migration until identity and DNS are stable.
Test-NetConnection fileserver01.contoso.com -Port 445
Resolve-DnsName fileserver01.contoso.com
For file-service or SMB symptoms, prove name resolution and port reachability before changing permissions or storage design.
Migration assessment findings:
- application uses hard-coded server name
- service account is local admin on old host
- file share ACLs include nested domain groups
- rollback window is four hours
This is a dependency and cutover problem, not just a copy operation. A strong answer preserves identity, ACLs, names, rollback, and validation steps.
For AZ-802 misses, label the failure type before reattempting: AD DS, hybrid management, compute, networking, storage, security, high availability, recovery, migration, or monitoring. If you miss because two answers seem technically possible, prefer the one that validates dependencies first, preserves existing identity and access requirements, creates a reversible path, and records evidence for operations.
Use the older AZ-800 and AZ-801 pages only for predecessor context. For new preparation, practice from AZ-802 first, then use older material to clarify terminology where a training provider or employer still names the split route.
When several unseen timed attempts are above roughly 75% and you can explain the identity boundary, connectivity path, rollback option, and monitoring evidence behind each answer, stop repeating familiar questions. Use remaining time for weak-domain drills and one final diagnostic.
