This cheat sheet is a fast, exam-focused review of everything on AZ-104 (Microsoft Azure Administrator). AZ-104 is an associate-level exam with hands-on configuration questions, so treat this as a consolidation aid for your final days — pair it with an Azure free-tier subscription and real lab practice, not instead of it.

1. Manage Azure Identities & Governance

ConceptWhat it means
Management groups → subscriptions → resource groups → resourcesThe scope hierarchy for RBAC and policy; settings inherit downward.
Azure RBACAssign built-in or custom roles (Owner, Contributor, Reader) at a scope.
Azure PolicyEnforce rules (audit, deny, append) across resources; group into initiatives.
Resource locksCanNotDelete or ReadOnly — prevents accidental changes regardless of RBAC.
TagsKey-value metadata for cost tracking, automation, and organization.
Azure AD/Entra users & groupsAssigned vs dynamic groups; guest users for external collaboration.
Cost Management + BudgetsTrack spend, set budgets and alerts, analyze cost by resource or tag.

Most-tested distinction: a resource lock blocks an action (delete/modify) regardless of a user's RBAC permissions. RBAC controls whether a user can attempt the action at all. Use both together for critical resources.

2. Implement & Manage Storage

Redundancy options

LRSLocally redundant — 3 copies in one datacenter.
ZRSZone redundant — copies across availability zones in one region.
GRS / GZRSGeo-redundant — async-replicated to a secondary region (GZRS adds zone redundancy in the primary).
RA-GRS / RA-GZRSAdds read access to the secondary region's replica.

Blob access tiers & lifecycle

HotFrequent access, highest storage cost, lowest access cost.
Cool / ColdInfrequent access (30+ / 90+ days), lower storage cost, higher access cost.
ArchiveRarely accessed; lowest cost but requires rehydration (hours) before reading.
Lifecycle management policyAutomatically tier or delete blobs based on age rules.

Access & data movement

SASShared access signature — scoped, time-limited access without sharing account keys.
Azure Files vs BlobFiles = SMB/NFS file shares (mountable as a drive); Blob = object storage for unstructured data.
AzCopy / Storage ExplorerCommand-line and GUI tools for bulk upload, download, and migration.
Soft delete / versioningRecover accidentally deleted or overwritten blobs within a retention window.

Most-tested distinction: LRS/ZRS protect against hardware/datacenter failure within a region; GRS/GZRS protect against a full regional outage. Read access (RA-) only matters if the app needs to read from the secondary during an outage.

3. Deploy & Manage Compute

Virtual machines & resiliency

Availability SetFault domains + update domains within one datacenter — protects against local hardware/maintenance failure.
Availability ZonePhysically separate datacenters in one region — protects against a full datacenter outage.
VM scale setsAuto-scale identical VM instances based on load or schedule.
VM extensionsPost-deployment configuration (Custom Script Extension, Desired State Configuration).
Managed disksStandard HDD/SSD, Premium SSD, Ultra Disk — pick by IOPS/throughput needs.

Deployment & containers

ARM templates / BicepDeclarative infrastructure-as-code; Bicep compiles down to ARM JSON.
Azure Container Instances (ACI)Run a single container without managing VMs or orchestration.
Azure App ServiceManaged PaaS hosting for web apps; deployment slots for staged rollouts.
Azure Kubernetes Service (AKS) — basicsManaged Kubernetes control plane; node pools scale the workload nodes.

Most-tested distinction: an Availability Set only protects against failures inside one datacenter; an Availability Zone protects against losing an entire datacenter. Zones are not available in every region — check before designing for them.

4. Implement & Manage Virtual Networking

ComponentPurpose
VNet & subnetsPrivate network address space; subnets segment it and host resources.
NSGFree, stateful 5-tuple packet filter applied to a subnet or NIC.
VNet peeringConnect two VNets privately over the Azure backbone; non-transitive by default.
Azure Load BalancerLayer 4 (TCP/UDP) traffic distribution — public or internal.
Application GatewayLayer 7 web traffic load balancer with URL-based routing and optional WAF.
VPN GatewayEncrypted site-to-site or point-to-site connectivity to on-prem.
Azure BastionRDP/SSH to VMs over TLS via the portal — no public IP needed on the VM.
Azure DNS / Private DNSHost public zones or private zones resolved only within linked VNets.

Load Balancer vs Application Gateway: Load Balancer works at the transport layer (any TCP/UDP traffic); Application Gateway understands HTTP(S) and can route by URL path or host header, and add a Web Application Firewall.

5. Monitor & Maintain Resources

ToolPurpose
Azure MonitorCentral platform for metrics, logs, and alerts across resources.
Log Analytics workspaceQuery collected log data with Kusto Query Language (KQL).
Alerts & action groupsTrigger notifications or automated actions when a metric/log condition is met.
Network WatcherDiagnose connectivity (IP flow verify, connection troubleshoot, packet capture).
Azure BackupScheduled, policy-based backup for VMs, files, and databases via a Recovery Services vault.
Azure Site RecoveryDisaster recovery — replicate VMs to another region for failover.
Update ManagerSchedule and track OS patching across VMs.

Most-tested distinction: Azure Backup restores data after loss or corruption; Azure Site Recovery fails over an entire workload to another region during an outage. They are complementary, not interchangeable.

Common Questions

Is a cheat sheet enough to pass AZ-104?

No. AZ-104 is an associate-level exam with scenario, configuration, and drag-and-drop questions that assume real hands-on Azure administration experience. A cheat sheet is a fast final-review aid to consolidate service names and when-to-use decisions — use it alongside labs, Microsoft Learn, and practice questions, not instead of them.

What is the difference between a Network Security Group and Azure Firewall?

A Network Security Group (NSG) is a free, stateful packet filter applied to subnets or NICs using 5-tuple allow/deny rules. Azure Firewall is a managed, stateful network firewall service with FQDN filtering and centralized policy for an entire virtual network or hub, not just a single subnet.

What is the difference between an Availability Set and an Availability Zone?

An Availability Set groups VMs across fault domains and update domains within a single datacenter to protect against local hardware failure and planned maintenance. An Availability Zone spans physically separate datacenters within an Azure region, protecting against an entire datacenter outage — a stronger guarantee, but not available in every region.

What is the passing score and cost for AZ-104?

700 out of 1000 (roughly 70%). The exam costs $165 USD, has around 40–60 questions, and a time limit of about 120 minutes.
