I was interviewed in May 2023.
Yes, it is possible to install Docker inside Docker using a feature called Docker-in-Docker (DinD).
Docker-in-Docker (DinD) allows you to run a Docker container inside another Docker container.
It is commonly used for testing and development environments where nested containers are required.
To enable DinD, you need to mount the Docker socket inside the container and run the container with the necessary privileges.

Terraform state file is used to store the state of your infrastructure managed by Terraform.
Terraform state file keeps track of the resources created by Terraform.
It helps Terraform understand the current state of the infrastructure.
State file is stored locally by default, but can also be stored remotely for collaboration.
It should be stored securely to prevent unauthorized access or modifications.
Use Python to read a txt file and convert its contents into structured data.
Open the txt file using the 'open' function in Python.

Parse the data into structured format such as dictionaries or lists.
I applied via LinkedIn and was interviewed in Mar 2023. There was 1 interview round.
List is mutable and ordered while tuple is immutable and ordered.
Lists can be modified while tuples cannot.
Lists are defined using square brackets [] while tuples use parentheses ().
Lists are used for collections of data that need to be changed while tuples are used for fixed collections of data.
Example of a list: my_list = [1, 2, 3]
Example of a tuple: my_tuple = (1, 2, 3)

I applied via Referral and was interviewed in Jul 2023. There were 3 interview rounds.
I implemented fault tolerance in AWS by using multiple Availability Zones, auto-scaling groups, and load balancers.
Utilized multiple Availability Zones to ensure redundancy and minimize downtime in case of failures in one zone
Implemented auto-scaling groups to automatically adjust capacity based on traffic patterns and maintain performance
Configured load balancers to distribute traffic evenly across instances and preve
RDS and EC2 need snapshots for data backup, disaster recovery, and creating new instances.
Snapshots provide a point-in-time backup of data stored in RDS and EC2 instances.
Snapshots are essential for disaster recovery in case of data loss or system failure.
Snapshots can be used to create new instances or restore existing ones to a previous state.
Snapshots help in scaling resources by creating copies of existing instance...
VPC Peering can be complex due to network configurations and security considerations.
VPC Peering involves connecting two separate VPCs to communicate with each other using private IP addresses.
It requires careful planning of IP address ranges to avoid conflicts.
Security groups and route tables need to be properly configured to allow traffic between peered VPCs.
Transitive peering is not supported, meaning VPC A cannot c...
