AZ-305 Practice Questions

You are designing a data solution for a company that needs to ingest millions of events per second from IoT devices. The solution must be able to capture this streaming data and make it available for multiple downstream consumers, including a real-time analytics engine and a long-term archival system. The ingestion service must be highly scalable and support event partitioning.

Which Azure service is the most appropriate for this data ingestion requirement?

A company has a set of on-premises virtual machines that they plan to migrate to Azure. Before the migration, they need to perform a comprehensive assessment to understand dependencies between VMs, determine the appropriate VM sizing in Azure, and estimate the monthly costs. The assessment process should be as automated as possible.

Which Azure tool should you recommend for this purpose?

A company is concerned about the security of its Azure Active Directory (Azure AD) tenant. They want to proactively detect and respond to potential identity-based risks, such as leaked credentials, sign-ins from anonymous IP addresses, and impossible travel to atypical locations. The solution should automatically force users to perform multi-factor authentication or reset their password when a high-risk event is detected.

Which Azure AD feature should be implemented?

You are designing the storage for a new application that requires extremely low latency and high throughput for read and write operations on its data files. The data will be accessed from a cluster of Linux virtual machines running a high-performance computing (HPC) workload. The storage solution must provide a fully managed file share that supports the NFSv3 protocol.

Which Azure storage service is the best fit for this requirement?

A media company is designing a solution to ingest and process a high-throughput stream of real-time analytics data from its global video platform. The solution must meet the following criteria:

• Ingest millions of events per second with low latency.
• Provide a durable, ordered buffer for events for at least 7 days.
• Allow multiple independent consumer applications to process the same stream of events concurrently, each at its own pace.
• Partition the data stream by user ID to enable parallel processing.

Which combination of Azure services provides the most appropriate architecture for the ingestion and buffering part of this solution?

A financial services company is designing a new three-tier application on Azure. The company has a strict security policy that requires all network traffic between the web, application, and data tiers to be inspected by a Network Virtual Appliance (NVA). The company also wants to centralize the management of this NVA and other shared services like DNS and Active Directory domain controllers. You need to design a network topology that meets these requirements.

Which network design should you recommend?

A retail company is migrating its e-commerce platform to Azure. The platform experiences massive, unpredictable traffic spikes during flash sales. The product catalog is stored in an Azure SQL Database. During sales, the database becomes a bottleneck due to an extremely high volume of read operations. The company needs a solution that can handle the read traffic without requiring a permanent, expensive scale-up of the primary database. The solution must minimize changes to the application's data access layer.

What is the most suitable solution to recommend?

An organization has deployed a critical application on a set of Azure Virtual Machines. The security team wants to ensure that administrative access (RDP and SSH) to these VMs is only possible from a secure, managed jump box and not directly from the internet. They also want to audit all administrative sessions. The solution should avoid exposing any public IP addresses on the VMs themselves.

Which Azure service should be recommended to meet these requirements?

A company has a hybrid cloud environment with resources both on-premises and in Azure. The governance team needs to enforce a consistent set of policies, such as requiring specific tags on resources and restricting deployments to certain regions, across both Azure and their on-premises servers. They want a single control plane to manage and audit compliance for all resources, regardless of their location.

What Azure service should be the cornerstone of this governance design?

You are designing a disaster recovery strategy for a stateful application running in Azure Kubernetes Service (AKS). The application uses Azure Disks for persistent storage via Persistent Volumes (PVs). The business requires a Recovery Point Objective (RPO) of 4 hours and a Recovery Time Objective (RTO) of 8 hours. The disaster recovery site will be in a paired Azure region.

You need to recommend a solution for backing up and restoring the application's state, including its Kubernetes objects and persistent data.
