AZ-900 Reliability, Predictability &
Manageability Practice Test 2026–2027
| Azure Resilience, Monitoring &
Management Questions
1. An organization wants an Azure-hosted application to remain operational if
one datacenter within an Azure region becomes unavailable. Which Azure
capability is most directly relevant?
A. Availability zones
B. Azure Policy
C. Resource locks
D. Azure Advisor
Answer: Availability zones
Rationale: Availability zones are physically separate datacenter locations within
an Azure region, each with independent power, cooling, and networking.
Deploying application components across zones can protect against a failure
affecting one datacenter.
,2. A company requires predictable application performance during planned
maintenance of Azure infrastructure. Which design provides the strongest
resilience?
A. Deploy all resources in one availability zone
B. Deploy redundant instances across availability zones
C. Use Azure Cost Management
D. Apply a resource lock
Answer: Deploy redundant instances across availability zones
Rationale: Distributing redundant application instances across availability zones
reduces the impact of infrastructure maintenance or localized failures. A single-
zone deployment creates a larger availability dependency.
3. Which Azure concept primarily describes the ability of a service to continue
operating despite component failures?
A. Reliability
B. Governance
C. Elasticity
D. Consumption
Answer: Reliability
Rationale: Reliability concerns a system's ability to consistently perform its
intended functions and recover from failures. Azure provides redundancy,
availability zones, monitoring, and other capabilities that support reliable
architectures.
4. An application experiences unpredictable traffic spikes. The organization
wants resources to automatically increase when demand rises and decrease
afterward. Which capability best addresses this requirement?
,A. Scalability
B. Resource locking
C. Compliance
D. Data residency
Answer: Scalability
Rationale: Scalability allows a workload to handle changes in demand. Azure
services can scale resources vertically or horizontally, and many services support
automatic scaling based on workload conditions.
5. Which characteristic is most closely associated with predictability in Azure?
A. Ability to forecast performance and costs
B. Ability to prevent all outages
C. Ability to eliminate administrative roles
D. Ability to remove resource dependencies
Answer: Ability to forecast performance and costs
Rationale: Predictability means organizations can better anticipate system
behavior, performance, and spending. Azure provides monitoring, pricing tools,
SLAs, autoscaling, and management capabilities that improve predictability.
6. A company wants centralized visibility into Azure resource performance and
operational conditions. Which service should it primarily use?
A. Azure Monitor
B. Azure Policy
C. Azure Resource Manager locks
D. Azure Cost Management only
Answer: Azure Monitor
, Rationale: Azure Monitor collects and analyzes metrics, logs, traces, and other
telemetry. It provides a central platform for observing Azure resources and
applications.
7. Which Azure service can automatically identify potential performance,
security, reliability, and cost improvements?
A. Azure Advisor
B. Azure DNS
C. Azure Storage
D. Azure Resource Graph
Answer: Azure Advisor
Rationale: Azure Advisor analyzes Azure deployments and provides personalized
recommendations across areas such as reliability, security, performance,
operational excellence, and cost optimization.
8. An administrator wants to prevent accidental deletion of a production
resource. Which Azure feature should be used?
A. Resource lock
B. Availability set
C. Azure Monitor
D. Autoscale
Answer: Resource lock
Rationale: Resource locks can prevent resources from being deleted or modified
unintentionally. Delete locks are particularly useful for protecting critical
production resources.
