Top 20 AWS Cloud Engineer Interview Questions

Our testing process has uncovered critical vulnerabilities in the website, such as SQL Injection and Cross-Site Scripting (XSS). Our performance testing also showed that the website can handle up to 10,000 concurrent users, which is 200% more than the expected traffic. Our efforts have helped the development team to prioritize and fix issues, resulting in a stable and secure website launch. As an experienced cloud tester, I have worked on various projects with different cloud technologies, such as AWS, Azure, and Google Cloud. In my previous role, I led a team in testing an e-commerce website that was migrated to AWS.

You’ve been tasked with setting up a disaster recovery plan for a critical workload in AWS. Describe the architecture and steps you would take to ensure data integrity and rapid recovery. Classic Load Balancer, the oldest type, balances both HTTP/HTTPS and TCP traffic but lacks some features available in ALB and NLB. CLB is generally used for legacy applications or when migrating existing applications to AWS without modifying their architecture. During my previous role as a Cloud Operations Engineer at XYZ Corp, we faced a major issue where our cloud-based application was experiencing severe latency issues.

What is meant by a packaged hybrid cloud, and what are some types of this service offering?

These resources will also perform the same tasks as the original ones from which the snapshots were made. On the other hand, Terraform is an open-source IaC tool developed by HashiCorp, which supports multiple cloud providers, including AWS, Azure, Google Cloud Platform, and others. aws cloud engineer Terraform uses its own language called HCL (HashiCorp Configuration Language), which is human-readable and easy to learn. Additionally, Terraform maintains state files that track the current state of your infrastructure, enabling better management of changes and rollbacks.

Demonstrating your ability to create efficient architectures and monitor resources usage to optimize costs will show that you are a valuable asset to the company’s cloud infrastructure team. Hiring managers want to ensure that you have a solid understanding of the core concepts in AWS architecture, as well as the ability to apply them in real-world situations. Knowing the difference between horizontal and vertical scaling is essential for designing and maintaining efficient and cost-effective cloud infrastructure. Demonstrating your knowledge in this area shows that you’re capable of making informed decisions when it comes to optimizing resources and performance. IAM roles play a critical part in ensuring security and proper access management within an AWS environment.

#1: What are the key benefits of Azure versus other cloud service providers?

6- Session policies- They are advanced policies that are passed as a parameter when a temporary session is programmatically created for a role or federated user. When an EC2 instance is launched, a private IP address is assigned to that instance at boot time. This private IP address is attached to the instance for its entire lifetime and can never be changed. EBS volume consists of virtual drives that can be easily backed up and duplicated by snapshots. An advanced answer will likely get more granular about the detail and concrete steps required to migrate web applications from on-premise to Azure. Primary and intermediate answers to this question could discuss broad patterns and best practices for migrations, such as rehosting, refactoring, rearchitecting, and rebuilding.
