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

Question 1

You have an Azure SQL database called SQL l and a multi-tier app called Appl. Users read data from SQL 1 using the Appl client once the backend service of the application has written data to them.

During periods of high utilization the users experience delays retrieving the data

You need to minimize how long it takes for data requests

What should you include in the solution?

Accepted Answer

Azure Cache for Redis

Answer

Azure Cache for Redis is an in-memory data store that significantly improves application performance by caching frequently accessed data. When users experience delays retrieving data from an Azure SQL database during high utilization, implementing a cache like Redis can store copies of this data closer to the application. This reduces the number of direct requests to the database, minimizes latency, and speeds up data retrieval for users, thereby alleviating performance bottlenecks.

Question 2

You are creating a state application that will manage many transactional components and include several Azure cloud services. Customer orders, billing, payment processing, inventory management, and delivery are handled by various cloud services.

You need to recommend a solution to enable the cloud services to asynchronously communicate transaction information by using XML messages.

What should you include in the recommendation?

Accepted Answer

Azure Queue Storage

Answer

Azure Queue Storage provides a simple and cost-effective solution for storing large numbers of messages that can be processed asynchronously by different cloud services. It's ideal for decoupling application components, allowing services like order processing, billing, and inventory to exchange transactional data, such as XML messages, without direct dependencies. This ensures reliable communication and processing, even if one service is temporarily unavailable, by holding messages until they can be consumed.

Question 3

You have an Azure SQL database with the name SQL l and a multi-tier app with the name Appl. Users utilize the Appl client to read data from SQL 1 that is written by the backend service of the App.

During periods of high utilization the users experience delays retrieving the data

You need to minimize how long it takes for data requests

What should you include in the solution?

Accepted Answer

Azure Cache for Redis

Answer

Azure Cache for Redis is an in-memory data store designed to significantly improve application performance by caching frequently accessed data. When users experience delays retrieving data from an Azure SQL database during high utilization, implementing Redis cache can store copies of this data closer to the application. This reduces the load on the primary database, minimizes latency, and speeds up data retrieval for users, effectively addressing performance bottlenecks.

Question 4

Several virtual machines are deployed by your business both on-premises and on Azure. ExpressRoute is installed and set up for connectivity from on-premises to Azure.

There are problems with network connectivity on certain virtual computers.

To determine whether packets from Azure to the virtual machines are being accepted or prohibited, you must study the network traffic.

Solution: Install and configure the Azure Monitoring agent and the Dependency Agent on all the virtual machines. Use VM insights in Azure Monitor to analyze the network traffic.

Does this meet the goal?

Accepted Answer

No

Answer

The proposed solution using Azure Monitoring agent and Dependency Agent with VM insights primarily focuses on VM performance, health, and dependency mapping, not detailed network packet flow analysis. To determine if packets are being accepted or prohibited and to study network traffic for connectivity issues, Azure Network Watcher is the appropriate service. Network Watcher's NSG flow logs and IP flow verify features are specifically designed to analyze network security group rules and packet flow, providing the necessary insights into network traffic acceptance or denial.

Question 5

You intend to distribute several Azure web app instances across various Azure regions.

* Support rate limiting.

* Balance requests between all instances.

* Ensure that users can access the app in the event of a regional outage.
Solution: You use Azure Front Door to provide access to the app.

Does this meet the goal?

Accepted Answer

Yes

Answer

Azure Front Door is a global, scalable entry-point that effectively meets all the specified requirements. It provides Layer 7 load balancing across multiple Azure web app instances deployed in different regions, ensuring optimal traffic distribution. Furthermore, Azure Front Door supports rate limiting through its Web Application Firewall (WAF) capabilities, and its global failover mechanism ensures that users can access the application even in the event of a regional outage, providing high availability and resilience.
