AZ-900 Practice Test 5 — 25 Questions

Question 1

A company uses Azure to run a virtual machine for development. They want to ensure that if the physical server hosting the VM fails, the VM is automatically restarted on another server within the same Azure datacenter. Which Azure SLA does this scenario relate to?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

99.9% VM SLA for a single instance. The scenario describes a single VM that automatically restarts on another physical host within the same datacenter after a hardware failure. This is covered by the Azure VM SLA for a single instance, which guarantees 99.9% uptime when you use premium SSD or ultra disks and have the VM deployed in a single availability zone or just within a datacenter. The SLA specifically addresses connectivity to the VM and its automatic recovery from host failures, not multi-instance redundancy.

Answer

99.95% VM SLA for multiple instances

Answer

99.99% SQL Database SLA

Answer

No SLA applied

Question 2

A company has a policy that all Azure resources deployed to production subscriptions must be tagged with a 'CostCenter' tag. They want to automatically prevent the creation of any resource that does not include this tag. Which Azure Policy effect should they use in their policy definition?

Accepted Answer

Deny. The Deny effect is correct because it actively prevents the creation or deployment of any Azure resource that does not comply with the policy rule, such as missing the required 'CostCenter' tag. Unlike Audit, which only logs compliance violations without blocking the operation, Deny enforces the policy at the time of the resource creation request, ensuring non-compliant resources are never provisioned.

Answer

Audit

Answer

DeployIfNotExists

Answer

Modify

Question 3

A company uses multiple Azure subscriptions for different departments. The finance team wants to monitor spending across all subscriptions and receive automated email alerts when a subscription's actual spending reaches 80% of its monthly budget. The team does not want to write custom scripts or use external tools. Which Azure feature should they use?

Accepted Answer

Azure Cost Management + Budgets. Azure Cost Management + Budgets is the correct feature because it allows you to create budgets at the subscription or resource group level, set alert thresholds (e.g., 80% of actual spend), and configure automated email notifications when the threshold is met—all without custom scripts or external tools. This directly addresses the finance team's requirement to monitor spending across multiple subscriptions and receive alerts.

Question 5

A company needs to deploy a consistent set of Azure resources (a virtual network, two subnets, and a network security group) into multiple environments: dev, test, and prod. The IT operations team wants to define these resources in a declarative file that can be deployed repeatedly and reliably to different resource groups. The team also wants to version control the file and have the ability to update all environments by redeploying the same file. Which Azure feature should the team use?

Accepted Answer

Azure Resource Manager (ARM) templates. Azure Resource Manager (ARM) templates are the correct choice because they provide a declarative JSON-based file that defines the infrastructure and configuration of Azure resources. This allows the team to deploy a consistent set of resources (virtual network, subnets, network security group) repeatedly and reliably across different resource groups and environments (dev, test, prod). ARM templates support version control, idempotent deployments, and can be used to update all environments by simply redeploying the same template file.

Question 10

A company deploys a web application on Azure App Service. During a marketing campaign, they expect traffic to double. The app uses a Standard tier App Service plan. They want to ensure that the additional load is handled without performance degradation while keeping costs minimal. Which action should they take?

Accepted Answer

Scale out the App Service plan by increasing the instance count.. Scaling out (increasing instance count) for the Standard tier App Service plan allows the application to handle the doubled traffic by distributing requests across multiple instances, ensuring no performance degradation. This approach is cost-minimal because the Standard tier supports manual scale-out without requiring a tier upgrade, and you only pay for the additional instances while they are needed.

Answer

Scale up the App Service plan to a Premium tier for more resources.

Answer

Enable autoscale on the existing plan to let Azure handle scaling automatically.

Answer

Deploy Azure CDN to cache static content.

Question 11

A company is evaluating cloud providers and needs to ensure that their data remains within a specific geographic boundary due to data sovereignty laws. Which cloud concept is most directly related to this requirement?

Accepted Answer

Region. Azure regions are discrete geographic locations containing one or more datacenters that provide the physical boundary for data residency. By deploying resources within a specific region (e.g., 'West Europe'), an organization ensures that data is stored and processed within that geographic boundary, directly addressing data sovereignty laws. Other concepts like Availability Zones or Latency do not enforce geographic data residency.

Answer
