Which Azure Storage service is optimized for storing large amounts of unstructured data, such as text or binary data, that can be accessed from anywhere in the world over HTTP or HTTPS?
Azure Table Storage
Azure Blob Storage
Azure Queue Storage
Azure Disk Storage
Azure Blob Storage is optimized for storing massive amounts of unstructured data, such as text and binary data. It provides highly scalable and available storage accessible from anywhere in the world with an internet connection via HTTP or HTTPS. Azure Disk Storage is intended for block storage for Azure VMs. Azure Queue Storage is for storing and retrieving messages, not unstructured data. Azure Table Storage provides storage for semi-structured NoSQL data.
Your company is deploying multiple resources in Azure for various projects. Your manager has asked you to implement a system to organize and attribute costs accurately for billing purposes. How can you accomplish this?
Use Azure Advisor to generate cost management recommendations for each department.
Implement tags to assign relevant metadata such as project name or department to each resource for detailed cost tracking.
Create a separate Azure subscription for each project to track costs independently.
Adopt infrastructure as code practices across the organization to manage costs and resources.
Using tags in Azure allows you to assign custom key-value pairs to resources, enabling you to categorize and track costs based on project, department, environment, or any other relevant classification for your organization. The correct answer results in granular tracking of costs, which aids in precise cost attribution per project or department. The incorrect answers either represent tools that are not primarily used for cost attribution (like Azure Advisor primarily for recommendations on practices), do not offer the level of detail required for this specific task (like a single Azure subscription without further classification), or exceed the scope of the question (like implementing full IaC practices, which might help with resource deployment but not directly with cost attribution).
Which cloud service model would be most suitable for a company that wishes to deploy an application without managing the underlying servers or operating systems?
Platform as a Service (PaaS)
In-house data center
Infrastructure as a Service (IaaS)
Software as a Service (SaaS)
Platform as a Service (PaaS) is the correct choice because it provides a complete development and deployment environment in the cloud, without the need for the client to manage the underlying infrastructure such as servers, storage, or operating systems. This allows the company to focus on the deployment and management of their applications only.
Infrastructure as a Service (IaaS) would be incorrect because it provides virtualized computing resources over the internet and the customer is still responsible for managing the servers and operating systems. Software as a Service (SaaS) would also be incorrect because it refers to cloud-based software that is provided on a subscription basis and is managed entirely by the service provider, which does not fit the scenario where a company wants to deploy its own application. An in-house data center would not qualify as a cloud service model and would involve managing the entire IT infrastructure on-premises.
A company wants to enhance the security of their Azure environment and ensure that users have more than one verification method before accessing Azure resources. Which Azure feature should they implement?
Multi-factor authentication (MFA)
Single sign-on (SSO)
Business-to-business (B2B) collaboration
Business-to-customer (B2C) services
The correct answer is Multi-factor authentication (MFA), which requires users to provide two or more verification methods – something they know (like a password), something they have (like a phone or hardware token), or something they are (like a fingerprint). MFA adds a critical second layer of security to user sign-ins and transactions. Single sign-on (SSO) provides a seamless user experience by enabling users to remember only one ID and password to access multiple applications, but it does not by itself ensure that multiple verification methods are used. Passwordless authentication allows users to sign in without a password by using other methods like a PIN or biometric verification, which supports the concept of MFA, but just offering passwordless options does not imply MFA is enabled. Business-to-business (B2B) and business-to-customer (B2C) refer to identity and access management solutions tailored for managing external user access, not specifically for enforcing multiple verification methods.
Your company has a multi-tier application deployed in Azure, and you are responsible for setting up monitoring to quickly identify any performance issues that may arise. You need to configure an alert that triggers when the CPU utilization of your virtual machines goes over 80% for a period of 15 minutes. Which Azure service should you use to create this performance alert?
Azure Service Health
Azure Monitor alerts
Azure Monitor alerts are used to create, manage, and route alerts based on the metrics from Azure services. In this case, to monitor the CPU utilization metric and trigger an alert when it exceeds a certain threshold for a specified time period, Azure Monitor alerts service is the appropriate choice. Azure Service Health is concerned with the status of Azure services, Azure Advisor provides recommendations, and Application Insights is more focused on application performance tracking, not infrastructure-level metrics such as CPU utilization.
