Azure Cost Management, Pricing and Tags
Cost questions test cost factors, pricing calculator, total cost of ownership, budgets, Cost Management capabilities, and tags for ownership and reporting.
How to study for AZ-900
Treat each AZ-900 item as a cloud fit decision: identify the cloud model, Azure service category, responsibility boundary, governance need, or management tool.
Core concepts
Concept 1
Azure Cost Management, Pricing and Tags questions reward Azure service selection and responsibility reasoning rather than memorizing portal labels.
Exam cue: Identify whether the item is about cloud concepts, Azure services, or management and governance.
Concept 2
The best answer identifies the cloud model, Azure resource, management boundary, security control, or governance tool that matches the scenario.
Exam cue: Separate Microsoft responsibility from customer configuration and data responsibility.
Concept 3
Eliminate answers that confuse IaaS, PaaS, and SaaS responsibilities or use a monitoring, cost, or governance tool for the wrong job.
Exam cue: Match the Azure tool to the requested outcome: deploy, secure, govern, monitor, or optimize cost.
Risk pitfalls and guardrails
Assuming cloud always removes customer responsibility.
Guardrail: Avoid answers that remove all customer responsibility, use monitoring for pricing estimates, use tags for network security, or confuse Azure Policy with RBAC.
Choosing a named Azure service without checking whether the scenario asks for compute, networking, storage, identity, governance, or monitoring.
Guardrail: Avoid answers that remove all customer responsibility, use monitoring for pricing estimates, use tags for network security, or confuse Azure Policy with RBAC.
Confusing reactive monitoring dashboards with proactive cost alerts or policy enforcement.
Guardrail: Avoid answers that remove all customer responsibility, use monitoring for pricing estimates, use tags for network security, or confuse Azure Policy with RBAC.
Memory anchors
Cost Factor
Azure cost can be affected by resource type, size, region, usage, storage, bandwidth, and licensing.
Pricing Calculator
The pricing calculator estimates costs for planned Azure resources.
TCO Calculator
The total cost of ownership calculator compares estimated on-premises and Azure costs.
Cost Management
Microsoft Cost Management helps analyze, monitor, and optimize Azure spending.
Budget
A budget tracks spending against a threshold and can trigger alerts.
Tag
A tag labels resources with name-value pairs for ownership, cost, automation, or organization.
Reserved Capacity
Reserved capacity can reduce cost for predictable usage commitments.
Consumption
Consumption-based billing charges for measured resource use.
Cost Alert
A cost alert notifies stakeholders when spending reaches configured thresholds.
Resource Cleanup
Deleting unused resources helps reduce ongoing cost.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
