Question 1easymultiple choice
Full question →A company wants to enforce a set of security policies across all their Azure subscriptions. They have created several individual policy definitions. Which Azure construct should they use to group these policies together and assign them as a single package?
Question 2easymultiple choice
Full question →A bank needs to keep some sensitive customer data on-premises due to regulatory requirements, but wants to use cloud services for less sensitive workloads. Which cloud deployment model should they adopt?
Question 3easymultiple choice
Full question →A cloud provider offers resources on-demand and measures usage. Customers pay only for what they consume. Which characteristic of cloud computing is this?
Question 4mediummultiple choice
Full question →A cloud provider purchases hardware in bulk and shares physical infrastructure among many customers, which allows them to offer lower prices per customer. This benefit is known as:
Question 5mediummultiple choice
Full question →A cloud provider uses virtualization technology to host multiple customers on the same physical server. Each customer's data, applications, and operating systems are logically isolated and secured from one another. Which characteristic of cloud computing does this scenario best describe?
Question 6easymultiple choice
Full question →A company can provision virtual machines in Azure without submitting a request or waiting for hardware procurement. Which cloud characteristic does this describe?
Question 7easymultiple choice
Full question →A company currently budgets for maximum capacity to handle peak loads, resulting in underutilized resources during off-peak times. They want a model where they can quickly adjust resources up or down based on demand. Which cloud characteristic directly addresses this concern?
Question 8mediummultiple choice
Full question →A company currently runs its application on-premises in a data center. The IT manager calculates that the cost per server per month is approximately $200 when considering hardware depreciation, electricity, cooling, and staff. The company is considering moving to Azure and discovers that Azure can provision the same server capacity for $150 per month, but only if the company commits to a three-year reservation. Which cloud concept best explains why Azure can offer a lower price even with the reservation commitment?
Question 9mediummultiple choice
Full question →A company currently runs its IT operations entirely on-premises. The finance team is evaluating moving to Azure and wants to understand the financial impact. They currently purchase new servers every five years as a large upfront capital expenditure (CapEx). In Azure, they would pay a fixed monthly subscription for virtual machines instead. This shift from a large upfront payment to a smaller monthly operational expense (OpEx) is a direct illustration of which cloud computing benefit?
Question 10hardmultiple choice
Full question →A company deploys a critical application across two Azure regions for disaster recovery. They want to automatically failover traffic to the secondary region if the primary becomes unavailable. They also want to improve performance by routing users to the closest region. Which Azure service should they use?
Question 11mediummultiple choice
Full question →A company deploys a critical application on Azure virtual machines across three different availability zones in the East US region. The application is designed to handle the failure of one zone by automatically failing over to the remaining healthy zones. Which type of failure does this architecture primarily protect against?
Question 12hardmultiple choice
Full question →A company deploys a critical application on Azure virtual machines. They want to ensure that the VMs are distributed across physically separate datacenters within a single Azure region to protect against a single datacenter failure. Which Azure feature should they use?
Question 13mediummultiple choice
Full question →A company deploys a line-of-business application on an Azure virtual machine. The IT team wants to ensure the application remains secure. According to the shared responsibility model, which of the following security tasks is the sole responsibility of the customer (the company)?
Question 14mediummultiple choice
Full question →A company deploys a mission-critical application across three Azure availability zones. The application is designed to continue operating without any interruption if an entire availability zone becomes unavailable. Which cloud computing characteristic does this scenario best illustrate?
Question 15mediummultiple choice
Full question →A company deploys a multi-tier application using Azure virtual machines. The web tier VMs must be evenly distributed across two distinct data centers within an Azure region to avoid a single point of failure from an infrastructure outage. Which Azure construct should they use to meet this requirement?
Question 16mediummultiple choice
Full question →A company deploys a multi-tier web application on Azure. The web tier and database tier must be in the same region for low latency, but the database tier must be in a different subnet and have restricted network access from the web tier only. Which Azure network solution should they use?
Question 17hardmultiple choice
Full question →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?
Question 18easymultiple choice
Full question →A company deploys a web application on Azure Virtual Machines across multiple availability zones within a single region. They need to distribute incoming network traffic across these VM instances to ensure high availability. Which Azure service should they use?
Question 19mediummultiple choice
Full question →A company deploys a web application on Azure VMs across two different physical locations within the same Azure region. These locations are isolated from each other in terms of power, cooling, and networking. If one location fails, the application remains available from the other location. Which feature achieves this?
Question 20mediummultiple choice
Full question →A company deploys an Azure SQL Database. The company is billed based on the amount of data stored and the number of transactions per second (DTUs). At the end of each month, the company receives an invoice that itemizes the exact usage and the corresponding charges. Which of the five essential characteristics of cloud computing does this billing model primarily demonstrate?
Question 21easymultiple choice
Full question →A company deploys their application across multiple availability zones in an Azure region. This is done to improve which aspect of the application?
Question 22mediummultiple choice
Full question →A company deploys three Azure virtual machines (VMs) that host a critical line-of-business application. All three VMs are located in the same Azure region. The company notices that during planned maintenance events triggered by the Azure platform, such as host OS updates, all three VMs are updated simultaneously, causing the application to become unavailable. The company requires that during such maintenance, at least two VMs remain running to preserve application uptime. Which Azure feature should the company implement to logically group the VMs and ensure they are updated in separate batches?
Question 23mediummultiple choice
Full question →A company deploys two Azure virtual machines in an availability set. The application requires that at least one VM remains running during Azure platform-initiated maintenance, such as operating system updates to the underlying host. Which component of the availability set directly ensures that the VMs are not updated at the same time?
