Technical Interview Questions
Review the top developer interview questions for Cloud Training asked by IT hiring managers in Pune. We practice these live during mock interview sessions.
Q1: Explain the difference between a Public Subnet and a Private Subnet in AWS VPC.
Answer: A Public Subnet has a route to an Internet Gateway, allowing resources inside (like web servers) to receive public traffic. A Private Subnet does not have a direct route to the Internet Gateway. To access the internet (e.g. for updates), resources in a private subnet must route traffic through a NAT Gateway located in a public subnet.
Q2: What is AWS IAM and how do you implement the principle of least privilege?
Answer: IAM (Identity and Access Management) manages access to AWS resources. To implement least privilege, you avoid using root credentials, create specific IAM users, group them by role, and attach policies that grant only the minimum permissions required to perform their specific tasks.
Q3: Explain the difference between Horizontal Scaling and Vertical Scaling.
Answer: Vertical Scaling (scaling up) means adding more power (CPU, RAM) to an existing server. Horizontal Scaling (scaling out) means adding more servers to your infrastructure resource pool, distributing load using a load balancer (more resilient).
Q4: What is AWS S3 and what are its storage classes?
Answer: S3 (Simple Storage Service) is an object storage service. Storage classes include S3 Standard (frequent access), S3 Standard-IA (infrequent access), S3 One Zone-IA (low-cost infrequent access), and S3 Glacier (archival storage with varying retrieval times).
Q5: What is an Elastic Load Balancer (ELB)?
Answer: ELB automatically distributes incoming application traffic across multiple targets, such as EC2 instances, containers, and IP addresses, ensuring high availability and fault tolerance.
1-to-1 Corporate Mock Interview Loops
During the final modules of the course, we schedule dedicated screensharing mock interviews. You write code live on shared editors, explaining your runtime complexity and database designs to prepare for real technical rounds.

Student Success Stories
Real feedback from students who completed our 1-to-1 virtual Cloud Training training.
"Mastering AWS was essential for my career growth. The 1-to-1 screen-sharing sessions with an active cloud engineer made configuring VPCs, subnets, and IAM policies very easy to learn. Great sandbox lab support."
Rajesh B.
Cloud Architect (Formerly SysAdmin), Wakad, Pune"The AWS infrastructure course was very practical. We deployed web applications on EC2, configured load balancers, and set up RDS database instances. Having a mentor to explain scaling policies was excellent."
Pooja L.
Cloud Engineer, Hinjewadi, Pune"The cloud security and monitoring modules are highly detailed. Learned standard network security group setups and CloudWatch alerts. The live staging deployment during the internship was a great experience."
