Versioning provides history, while lifecycle cleanup bounds retained versions under policy. A versioning switch alone can grow storage indefinitely. This matters here because a blob has previous versions but a restore script downloads only the current revision. How can older data be retrieved.

Lifecycle policies can remove eligible past versions. Recovery expectations must align with the configured cleanup window.

Hierarchical namespace supports directories and ACLs for data-lake workloads, with Blob API integration. Design must check feature compatibility.

SMB traffic depends on TCP 445 reachability unless supported alternate network connectivity is used. Share permission changes cannot correct a network port block. This matters here because an auditor wants accidental deletion of an entire blob container to be recoverable for 14 days. Which feature must….

Container deletion removes the container namespace; enable container soft delete for the required recovery interval rather than relying only on deleted-blob retention.

Blob soft delete protects individual blob objects and versions, not an accidental deletion of the entire container. A 14-day container-level recovery objective requires container soft delete with the appropriate retention period.

A deleted container must be discovered through the appropriate deleted-container listing/restore operation while its retention window remains open.

Directory traversal can be required to reach child objects. File read permission alone does not bypass missing parent execute rights.

Archived blobs are not directly readable. Rehydration moves the object to an accessible tier and may take hours depending on priority.

The site needs the compatible hosting-plan resource ID; an identity ID is a different resource type and cannot repair that missing dependency.

A repeat invocation can't supply a missing App Service plan reference. Correct the application's plan ID and its inferred or explicit dependency first.

Previewing a deployment cannot manufacture a missing plan or repair the web app's invalid hostingPlan reference. Check the planned resource ID and dependency graph.

Deployment scope affects available resource types and evaluation context. A resource-group template cannot simply be run as a subscription-scoped deployment.

The create command applies the deployment; it is not the requested dry-run review. Use the group-scoped what-if operation to inspect predicted changes without applying them.

A service principal identifier describes the caller, not the resource diff. The group-scoped what-if operation is the nonmutating deployment preview.

Complete mode can remove resources omitted from supported deployment scopes, while incremental mode usually retains them. Destructive changes require explicit approval.

The caller identity does not determine which resources a deployment may delete. Review the proposed changes, mode, and template before any apply operation.

Module outputs are explicit values made available to callers. A variable inside a module is not automatically visible in the parent. This matters here because a what-if report includes a deletion and the team expected only additions.

What-if only predicts creates and modifications without applying them. An authorized group-scoped create operation is needed to provision the Bicep resources.

Bicep targetScope selects the deployment level. Resource groups and policy assignments can use subscription context under appropriate templates.

Conditional resources can be omitted, so unguarded references can fail. The dependency graph and expressions must handle the disabled case.

Azure Resource Manager enforces resource type availability at scopes. Changing a command flag alone cannot make a resource valid at the wrong scope.

A preview does not resolve the mismatch between the template's declared target scope and the deployment command. Execute the correct resource-group-scoped command after validation.

Bicep targetScope selects the deployment level. Resource groups and policy assignments can use subscription context under appropriate templates. This matters here because the operator used az deployment sub create but the file expects a resource-group target.

VM custom data makes bootstrap content available, but whether scripts execute depends on the guest image and cloud-init or other handlers. This matters here because a custom script extension fails and the VM Agent status reads Not Ready.

Passing user data to a VM is not identical to executing it. A compatible image and initialization configuration are required.

SSH public-key login avoids password reuse and supports controlled key management. The VM stores only the public key for verification. This matters here because a custom script extension fails and the VM Agent status reads Not Ready.

Zones provide distinct facility-level fault isolation in supported regions. An availability set alone does not span separate zones.

Managed disk retention is conditional on delete settings and separate cleanup. VM deletion does not guarantee every disk is preserved.

Concentrating instances in one fault and update domain defeats distribution across failure and planned-maintenance boundaries. An availability set uses multiple fault/update domains for supported VMs.

Passing user data to a VM is not identical to executing it. A compatible image and initialization configuration are required. This matters here because a planned host maintenance event reboots all VMs placed outside any availability design.

Availability sets reduce host-level correlated failures but do not create independent zonal or regional facilities.

Managed disks provide durable Azure storage tied to the VM, whereas temporary disks can lose data on deallocation or host events. This matters here because a planned host maintenance event reboots all VMs placed outside any availability design.
