Microsoft Azure Fundamentals Practice Test (AZ-900)

Azure Cost Management budgets enable organizations to set spending thresholds and receive notifications as expenses approach those limits. This helps in proactively managing costs and preventing budget overruns.

Azure Advisor provides recommendations to optimize resources but does not offer spending alerts.

Azure Pricing Calculator estimates costs before deployment.

Azure Resource Tags help organize resources but do not monitor spending.

Manageability is a key benefit of cloud computing that allows organizations to efficiently oversee and control their IT resources using centralized management tools and automation provided by cloud platforms. This reduces administrative overhead and simplifies operations.

Reliability refers to the ability of a system to operate continuously without failure. Scalability is about adjusting resources to meet demand. Elasticity involves automatic scaling of resources up or down. While these are important benefits, they do not specifically focus on simplifying resource management.

Platform as a Service (PaaS) is the most appropriate choice in this scenario. PaaS provides a complete development and deployment environment in the cloud, allowing developers to build, test, and deploy applications without worrying about managing the underlying infrastructure, operating systems, or middleware. It offers the necessary tools and services to support the entire application lifecycle. Infrastructure as a Service (IaaS) would require the company to manage operating systems and middleware themselves, while Software as a Service (SaaS) delivers fully functional applications over the internet, which doesn't suit the need for custom application development.

When creating an Azure virtual machine, specifying a virtual network is mandatory because the VM needs to be connected to a network to function properly. The virtual network allows the VM to communicate with other resources and services.

While a public IP address, a network security group, and joining an Azure Active Directory domain are optional configurations, the virtual network is essential for the VM's connectivity.

This statement is false. Azure Advisor provides personalized recommendations to help you optimize your Azure resources in areas such as cost, performance, security, and high availability. It does not detect or block security threats in real-time; that functionality is provided by services like Microsoft Defender for Cloud.

Cloud service providers that comply with international security standards offer assurance that they are following best practices and legal requirements to protect data. This compliance helps to provide a safer environment for the organization's data and applications, reduces the risk of breaches, and assists in meeting regulatory requirements. It simplifies the legal and regulatory compliance challenges that an organization might face, especially when operating globally. Incorrect answers highlight benefits that are either too specific to general cloud advantages or do not directly relate to the governance aspect brought by adherence to security standards.

Cloud computing is the model that provides on-demand network access to a shared pool of configurable resources such as networks, servers, storage, applications, and services. This model requires minimal management effort or service provider interaction, this allows for rapid provisioning and scalability.

Virtualization is a technology that creates virtual versions of physical components but does not inherently offer on-demand network access to shared resources.

Edge computing refers to processing data at the edge of the network, close to the source of data generation, which doesn't necessarily involve shared pools of resources.

Distributed computing involves multiple systems working on a shared task but lacks the on-demand self-service and broad network access features of cloud computing.

Serverless computing allows developers to run code without provisioning or managing servers. The cloud provider automatically handles the infrastructure, scaling, and provisioning, enabling developers to focus on writing code. Billing is based on the execution time of the code, which aligns with the company's requirements. Infrastructure as a Service (IaaS) requires managing virtual machines and infrastructure. Platform as a Service (PaaS) reduces some management overhead but doesn't offer billing based solely on code execution time. Software as a Service (SaaS) provides fully managed applications but doesn't allow for custom application development.

Scalability is the cloud benefit that allows a system to handle increasing workloads by adding resources as needed, ensuring performance during high demand. High availability focuses on maximizing uptime and ensuring the system is operational, but does not directly address adding resources to handle increased demand. Reliability pertains to the consistency of system performance, and disaster recovery involves restoring services after a failure, neither of which specifically address the need to handle increased traffic.

Microsoft Purview provides a unified data governance service that helps organizations manage and govern their on-premises, multi-cloud, and software-as-a-service (SaaS) data. It offers a comprehensive set of capabilities to map, catalog, understand, classify, and protect data across different data sources. This helps organizations maintain compliance with regulations and keep data secure.

This statement is false. In PaaS, the cloud provider manages the underlying infrastructure, including the operating system and server hardware. Developers can focus on deploying and managing their applications without worrying about the underlying infrastructure components.

The company is experiencing the benefit of manageability. Cloud computing offers centralized management tools that simplify administration tasks like monitoring, updating, and policy enforcement across all resources. While scalability refers to the ability to adjust resources based on demand, high availability ensures systems are operational with minimal downtime, and cost efficiency relates to reduced expenses. These are benefits of cloud computing but do not specifically address the centralized administration of resources.

Microsoft Defender for Cloud is a comprehensive security management solution that provides continuous assessment of your Azure resources, identifies vulnerabilities, and offers recommendations to enhance your security posture. It also includes advanced threat protection to detect and respond to active threats.

Azure Monitor focuses on collecting, analyzing, and acting on telemetry data from your applications and infrastructure but is not specifically designed for security monitoring.

Azure Advisor provides personalized recommendations to optimize your Azure deployments for cost, performance, and reliability but does not focus on security vulnerabilities or threat detection.

Azure Firewall is a managed network security service that protects your Azure Virtual Network resources but does not provide the comprehensive security management and threat detection capabilities of Microsoft Defender for Cloud.

Azure does not only offer fixed monthly fees, it provides a consumption-based model that allows customers to pay only for the resources they use. This model is more flexible and can be cost-effective for many users who prefer to pay for actual usage rather than a flat rate.

The consumption-based model is a billing approach where users pay only for the resources they consume, such as storage, processing time, or bandwidth, rather than paying for hardware or software licenses upfront. This model offers flexibility and cost savings since users are not required to invest in their own computing infrastructure and can scale their usage up or down according to their needs. Fixed cost models, while they can exist in some cloud scenarios, typically involve a predetermined fee regardless of the actual usage, which is not the essence of the consumption-based model. Sliding scale and free trial are not billing models associated with regular cloud service consumption.
