10+ AWS Administrator Interview Questions and Answers

Autoscaling groups can be implemented with load balancer by configuring the autoscaling group to use the load balancer as its target group.

• Create a load balancer and target group

• Create an autoscaling group and configure it to use the load balancer target group

• Set up scaling policies and thresholds for the autoscaling group

• Test the autoscaling group by simulating traffic to trigger scaling events

Network Load Balancer operates at the transport layer and Application Load Balancer operates at the application layer.

• Network Load Balancer is used for handling high traffic and provides low latency.

• Application Load Balancer is used for routing HTTP/HTTPS traffic and provides advanced routing features.

• Network Load Balancer supports TCP, UDP, and TLS protocols while Application Load Balancer supports HTTP/HTTPS protocols.

• Network Load Balancer is ideal for handling millions of ...read more

S3 is a scalable object storage service that allows users to store and retrieve data from anywhere on the web.

• S3 stands for Simple Storage Service

• It is highly scalable and can store virtually unlimited amounts of data

• It offers different storage classes such as Standard, Infrequent Access, and Glacier

• Standard storage class is for frequently accessed data, Infrequent Access is for data that is accessed less frequently, and Glacier is for long-term archival storage

• S3 can be used...read more

NACL and Security Hub are both AWS services, but they serve different purposes.

• NACL (Network Access Control List) is a firewall that controls inbound and outbound traffic at the subnet level.

• Security Hub is a security service that provides a comprehensive view of security alerts and compliance status across AWS accounts.

• NACL operates at the network layer (Layer 3) of the OSI model, while Security Hub operates at the application layer (Layer 7).

• NACL rules are stateless, meanin...read more

AWS is a cloud computing platform that provides a wide range of services. EC2 is a service that provides scalable computing capacity.

• AWS is a cloud computing platform that offers services such as storage, databases, analytics, and more

• EC2 is a service that provides resizable compute capacity in the cloud

• EC2 instances are virtual machines that can be launched in the cloud and can be configured to meet specific needs

• EC2 instances can be used for a variety of purposes such as ho...read more

I have experience using a variety of AWS services including EC2, S3, RDS, IAM, CloudWatch, and Lambda.

• EC2 (Elastic Compute Cloud) for scalable virtual servers

• S3 (Simple Storage Service) for object storage

• RDS (Relational Database Service) for managed databases

• IAM (Identity and Access Management) for user permissions

• CloudWatch for monitoring and logging

• Lambda for serverless computing

Our CI/CD pipeline is automated using Jenkins and AWS CodePipeline.

• We use Jenkins to build and test our code.

• We use AWS CodePipeline to deploy our code to different environments.

• We have automated testing and quality checks in place to ensure code quality.

• We use Git for version control and pull requests for code reviews.

• We have a separate staging environment for testing before deploying to production.

Lambda is a serverless computing service while load balancers distribute traffic across multiple servers.

• Lambda allows running code without provisioning or managing servers

• Load balancers improve application availability and scalability

• Lambda can be triggered by events such as changes to data in an S3 bucket

• Load balancers can be used to distribute traffic across EC2 instances or containers

T2 instance is a type of Amazon EC2 instance that provides a baseline level of CPU performance with the ability to burst above the baseline.

• T2 instances are designed to provide cost-effective computing for applications that don't require sustained high CPU performance.

• They are ideal for workloads that experience short periods of high CPU usage, such as web servers, development environments, and small databases.

• T2 instances earn CPU credits when they operate below baseline per...read more

AWS (Amazon Web Services) is a cloud computing platform that offers a wide range of services for businesses and individuals.

• Provides on-demand computing resources like servers, storage, databases, networking, etc.

• Offers services such as EC2 (Elastic Compute Cloud), S3 (Simple Storage Service), RDS (Relational Database Service), etc.

• Allows users to scale resources up or down based on demand, pay only for what they use, and access services globally.

• Used by companies of all size...read more

CI/CD is a software development practice that involves continuous integration and continuous delivery/deployment.

• Continuous Integration (CI) involves automatically building and testing code changes frequently.

• Continuous Delivery (CD) involves automatically deploying code changes to production.

• CI/CD helps in reducing manual errors, improving code quality, and increasing deployment frequency.

• Popular tools for CI/CD include Jenkins, GitLab CI/CD, and AWS CodePipeline.

D/W SG (Security Groups) and NACL (Network Access Control Lists) are AWS security features for controlling traffic.

• Security Groups (SG) are stateful, meaning they remember the state of connections. For example, if you allow inbound traffic on port 80, the response traffic is automatically allowed.

• Network Access Control Lists (NACL) are stateless, meaning you must explicitly allow both inbound and outbound traffic. For example, if you allow inbound traffic on port 80, you must...read more
