How to study for AZ-104

Treat each AZ-104 item as an admin workflow: identify the scope, resource type, access boundary, deployment method, monitoring signal, or recovery requirement.

Core concepts

Concept 1

Azure Files, Blob Storage and Lifecycle Features questions reward operational Azure administration judgment rather than simple service-name recall.

Exam cue: Identify the Azure scope: tenant, management group, subscription, resource group, resource, subnet, or identity.

Concept 2

The best answer identifies the scope, resource type, access path, deployment method, monitoring signal, and recovery requirement.

Exam cue: Match the tool to the administrative task: manage access, deploy, secure, monitor, back up, or troubleshoot.

Concept 3

Eliminate answers that confuse RBAC with policy, public access with private access, monitoring with backup, or templates with manual changes.

Exam cue: Prefer least privilege, repeatable deployment, protected storage, private networking, and validated recovery.

Risk pitfalls and guardrails

Using Azure Policy when the question asks who is allowed to perform an action.

Guardrail: Avoid answers that confuse RBAC with Policy, tags with network controls, dashboards with backup, or public exposure with secure private access.

Opening public access when private endpoints, service endpoints, or NSGs meet the requirement.

Guardrail: Avoid answers that confuse RBAC with Policy, tags with network controls, dashboards with backup, or public exposure with secure private access.

Assuming backup exists before checking vault, policy, retention, and restore validation.

Guardrail: Avoid answers that confuse RBAC with Policy, tags with network controls, dashboards with backup, or public exposure with secure private access.

Memory anchors

Azure File Share

An Azure file share provides managed file storage accessible through standard file protocols.

Blob Container

A blob container organizes blobs inside a storage account.

Hot Tier

The hot tier fits frequently accessed blob data.

Cool Tier

The cool tier fits infrequently accessed data with lower storage cost and higher access cost.

Archive Tier

The archive tier fits rarely accessed data with offline retrieval.

Blob Soft Delete

Blob soft delete helps recover blobs after accidental deletion.

Container Soft Delete

Container soft delete helps recover deleted containers within retention.

File Snapshot

An Azure Files snapshot captures a point-in-time view of a file share.

Lifecycle Rule

Lifecycle management transitions or deletes blobs based on rules.

Blob Versioning

Blob versioning keeps previous versions of blobs for recovery or audit.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Knowledge Check (after reading)

Short check-up to confirm understanding of this module.

Check-up Questions

1-2 question checkpoint

A department needs a managed SMB file share that Windows and Linux clients can mount concurrently. Which Azure Storage resource should be created?

An Azure Files share rejects new writes because its configured quota has been reached. Existing files must remain available. What should the administrator do?

Answer all questions to submit.
