Q1

A financial services company is developing a new loan processing application on Azure. The application must support user sign-ups using social identity providers like Google and Facebook, as well as traditional email-based accounts. The solution must provide a fully managed service for user registration, sign-in, profile management, and password reset, with the ability to customize the user interface. Which Azure service is specifically designed to meet these requirements for a consumer-facing application?

Q2

A development team is building a solution that ingests high-volume telemetry data from IoT devices. The data must be stored durably and cost-effectively for long-term archival and occasional batch analysis. Individual data points are small (less than 1KB), and the primary write pattern involves appending new data to existing logs. Which type of Azure Storage blob is optimized for this append-only workload?

Q3

You are designing the storage for a new application that will run on multiple Azure VMs. The application requires a shared file system that can be mounted simultaneously by these VMs using the Server Message Block (SMB) protocol. The solution should not require you to set up and manage a separate file server VM. Which Azure Storage service provides this capability?

Q4

A developer needs to create a lightweight, event-driven background task that runs in response to a new message being added to an Azure Storage Queue. The task involves minimal processing and should be implemented with the least amount of boilerplate code and infrastructure management. Which Azure PaaS compute service is the most suitable choice for this scenario?

Q5

You are configuring an Azure App Service Web App that hosts a critical e-commerce site. To ensure high availability and resilience against single-rack hardware failures within a datacenter, you deploy multiple instances of the Web App. Which Azure concept automatically distributes these instances across different hardware units to achieve this?

Q6

A developer is creating a custom retry policy for an application that interacts with Azure Table Storage. The policy must retry an operation only if a 'Conflict' (HTTP status code 409) is returned and the maximum number of retries has not been exceeded. All other HTTP status codes or exception types should cause the operation to fail immediately. Which condition correctly implements the logic to stop retrying if the status code is NOT a conflict?

Q7

You are architecting a solution that requires a messaging service for decoupling a front-end web application from a set of back-end processing services. Multiple, independent back-end services need to receive copies of the same message published by the front end. For example, when a new order is placed, one service should handle invoicing, another should update inventory, and a third should notify shipping. Each service must process the message independently. Which Azure messaging service provides this publish/subscribe functionality?

Q8

You are tasked with securing an Azure VM that hosts a web server. The VM must be accessible from the internet on TCP port 443 (HTTPS), but all other inbound traffic from the internet should be denied. However, the VM must be able to communicate with other VMs in the same virtual network on all ports. Which Network Security Group (NSG) rule configuration is required to meet these requirements?

Q9

A developer needs to provide temporary, read-only access to a specific blob in an Azure Storage account for an external client application. The access should expire in 24 hours. The main storage account keys must not be shared with the client. Which security mechanism should be generated and provided to the client?

Q10

You are deploying a multi-tier application to Azure. The web tier consists of four VMs, and the business logic tier consists of two VMs. You need to ensure that a planned maintenance event by Microsoft does not cause an entire tier to become unavailable. How should you configure the VMs to achieve this goal?
