FREE Designing Microsoft Azure Infrastructure Solutions (AZ-305) Questions and Answers

Question 1

A solution for the Azure IoT Hub that will contain 50,000 IoT devices is what you are designing. Temperature, device ID, and time data will all be streamed by each device.

Every second, 50,000 records will be written on average. Near real-time visualization of the data will be used. You must suggest a service that can store and search the data.

Which two services would you suggest?

Accepted Answer

Azure Time Series Insights

Answer

For streaming IoT data from 50,000 devices with high write volume and near real-time visualization, Azure Time Series Insights is ideal for storing, visualizing, and analyzing time-series data at scale. Azure Cosmos DB SQL API is also a strong choice due to its ability to handle high-volume, low-latency writes and reads, support for SQL queries, and global distribution capabilities, making it suitable for storing and searching the raw or processed IoT data.

Question 2

To satisfy the security and compliance requirements after migrating App1 to Azure, you must enforce the data modification restrictions. What should you do?

Accepted Answer

Implement Azure resource locks

Answer

To enforce data modification restrictions and prevent accidental or unauthorized changes to resources, Azure resource locks are the most appropriate solution. These locks can be applied to subscriptions, resource groups, or individual resources, preventing users from deleting or modifying critical resources, even if they have appropriate Azure RBAC permissions. RBAC assignments control who can do what, but locks prevent specific actions regardless of permissions.

Question 3

You must suggest a remedy that satisfies App1's data specifications. Which deployment strategy should you advise for each availability zone that houses an instance of App1?

Accepted Answer

An Azure Cosmos DB that uses multi-region writes

Answer

For an application requiring high availability across multiple availability zones and low-latency data access, especially with data modification restrictions and the need for a robust database, Azure Cosmos DB with multi-region writes is the optimal choice. It provides global distribution, automatic failover, and guarantees low-latency reads and writes across multiple regions/zones, ensuring data consistency and resilience. This capability is superior for distributed write scenarios compared to other options.

Question 4

You are creating a program that will provide users with content aggregation. For the application, you must suggest a database solution. The answer must adhere to the following criteria:

- Support SQL commands
- Support multi-master writes
- Guarantee low latency read operations
What should you include in the recommendation?

Accepted Answer

Azure Cosmos DB SQL API

Answer

Azure Cosmos DB SQL API is the ideal solution for these requirements. It is a globally distributed, multi-model database service that natively supports SQL queries (SQL API). Crucially, it offers multi-master writes, allowing data to be written to multiple regions simultaneously for high availability and low-latency writes, and its design also guarantees low-latency read operations, making it perfect for content aggregation applications needing fast data access.

Question 5

You intend to set up an HPC cluster in Azure that will make use of a third-party scheduler. You must suggest a method for setting up and controlling the HPC cluster node. What should the recommendation contain?

Accepted Answer

Azure Cyclecloud

Answer

Azure CycleCloud is specifically designed for creating, managing, operating, and optimizing HPC clusters in Azure. It provides a simple way to provision HPC environments, integrate with third-party schedulers (like Slurm, PBS Pro, LSF, Grid Engine), and manage cluster nodes. This makes it the perfect tool for setting up and controlling an HPC cluster node with a third-party scheduler.
