A few real questions from this free bank, with full explanations. Use the practice tool above for the whole set.
- 1. Cloud Concepts
A company wants compute capacity to automatically increase during busy periods and decrease when demand falls, without manual intervention. Which cloud characteristic is this?
- a.High availability
- b.Elasticity
- c.Disaster recovery
- d.Data residency
Answer: b
Explanation: Elasticity is the automatic adding and removing of resources to match demand in real time. High availability keeps services running despite failures, disaster recovery restores service after an outage, and data residency concerns where data is stored geographically.
- 2. Cloud Concepts
Under the shared responsibility model, which task is always the customer's responsibility regardless of the service model?
- a.Managing its own data and user access
- b.Securing the physical datacenter
- c.Maintaining the host hypervisor
- d.Replacing failed disks
Answer: a
Explanation: The customer is always responsible for its data, identities, and access management no matter the model. Physical security, the hypervisor, and hardware maintenance are always Microsoft's responsibility.
- 3. Cloud Concepts
An organization keeps sensitive records in its own datacenter but bursts to Azure for extra capacity at peak times, connecting the two. Which deployment model is this?
- a.Public cloud
- b.Hybrid cloud
- c.Private cloud
- d.Community cloud
Answer: b
Explanation: A hybrid cloud connects a private environment with the public cloud so workloads and data can move between them. A pure public or private cloud uses only one environment, and community cloud is shared among organizations with common concerns.
- 4. Core Azure Services
A developer wants to run small pieces of code in response to events and be billed only when the code executes. Which Azure service is designed for this?
- a.Azure Virtual Machines
- b.Azure App Service
- c.Azure Functions
- d.Azure Kubernetes Service
Answer: c
Explanation: Azure Functions is a serverless, event-driven compute service billed per execution. Virtual Machines and App Service run continuously, and AKS orchestrates containers rather than billing per individual function execution.
- 5. Core Azure Services
Which Azure storage service is best suited to store large amounts of unstructured data such as images, video, and backups?
- a.Azure Table storage
- b.Azure Queue storage
- c.Azure Files
- d.Azure Blob storage
Answer: d
Explanation: Azure Blob storage is optimized for unstructured object data like media and backups. Table storage holds NoSQL key-value data, Queue storage passes messages, and Files provides SMB file shares.
- 6. Core Azure Services
Which compute service lets you fully control and manage the guest operating system, giving the most configuration flexibility?
- a.Azure Virtual Machines
- b.Azure Functions
- c.Azure App Service
- d.Azure Container Instances
Answer: a
Explanation: Azure Virtual Machines are IaaS, giving you full control over the guest OS and installed software. Functions, App Service, and Container Instances are more managed and abstract away OS management.
- 7. Security and Compliance
A security team wants to require a second verification factor and enforce sign-in rules based on user location and device state. Which capabilities provide this?
- a.Resource locks and tags
- b.Blob storage tiers
- c.VNet peering
- d.Multifactor authentication and Conditional Access
Answer: d
Explanation: Multifactor authentication adds a second factor, and Conditional Access enforces policies based on signals such as location and device. Resource locks, storage tiers, and VNet peering are unrelated to sign-in security.
- 8. Management and Governance
An administrator must ensure resources can only be deployed to approved Azure regions across the organization. Which tool enforces this rule?
- a.Azure Monitor
- b.Resource locks
- c.Azure Policy
- d.Azure Advisor
Answer: c
Explanation: Azure Policy enforces organizational rules such as allowed regions and reports on compliance. Azure Monitor observes telemetry, resource locks prevent deletion or modification, and Advisor gives recommendations but does not enforce policy.
- 9. Management and Governance
To prevent a critical resource from being accidentally deleted, which feature should an administrator apply?
- a.A tag
- b.A resource lock (CanNotDelete)
- c.A network security group
- d.An availability zone
Answer: b
Explanation: A resource lock set to CanNotDelete prevents accidental deletion while still allowing use. Tags label resources, network security groups filter traffic, and availability zones concern resiliency, not deletion protection.
- 10. Pricing and Support
A company wants to estimate the monthly cost of a proposed set of Azure services before deploying them. Which tool should it use?
- a.The Total Cost of Ownership (TCO) Calculator
- b.The Azure Pricing Calculator
- c.Azure Advisor
- d.Microsoft Cost Management
Answer: b
Explanation: The Pricing Calculator estimates the cost of a proposed configuration of Azure services before deployment. The TCO Calculator compares on-premises versus Azure, Advisor recommends optimizations, and Cost Management analyzes actual spend after deployment.
