Two Interview questions you can always expect !!
Question 1: Tell me about yourself! or Introduce yourself
Suggestion:
Pretty common, but you want to be prepared for this to differentiate yourself from the crowd.
Most people start rambling about all their experiences, their schooling, and the certifications they have.
That doesn’t help the company at all.
They’re not actually hiring for that.
They’re hiring because they have a problem, and they need to find someone who can help them solve it
So, when companies ask me about myself, for example, I give a brief short (few lines like “Connect your experience to the job: Tailor your response to align with the job description and the company’s needs. Emphasize how your skills and experience make you an ideal candidate for the Azure Cloud position you’re interviewing for. For example, “I noticed that this role requires expertise in [mention a specific skill or area], which I’ve honed over the years. I’m excited about the opportunity to contribute to [Company Name] by leveraging my Azure Cloud experience.””)
and then flip the question on them and answer something like this, “You know, I have a lot of experience that I could talk about, but I don’t want to bore you with that. Could you let me know the specific problem you’re hiring for, and I can tell you about my experience in that area?”
Boom!
Now you are addressing their specific problem and identifying how my skill set will add value to their company.
Question 2: Any questions that you would like to ask?
Suggestion:
Any question that you would like to ask;
Make sure you stand out by asking
“Based on everything that we discussed today about my background and my experience, is there any reason why you wouldn’t offer me this job?”
Yes, it feels uncomfortable.
But the reason why you want to ask this question is it gives you the opportunity to overcome any objections they may have. You have to remember that you’re selling your services and a good salesperson is good at handling objections.
They might say, “Hey, you know what? We’re not sure you have the right experience that we’re looking for right now.”
This gives you a chance to offer a rebuttal and clear up any misconceptions they may have about you.
As uncomfortable as this question may be, it saves you heartache in the long run.
This question will clarify exactly what their needs are and why you might not be the right fit… instead of feeling like you killed an interview and finding out you still didn’t get the job.
Follow Up –
Finally, you must send an email to the person who interviewed you to thank them for their time. Remember, they’re giving you something that they can never get back: their time.
And it’s only right to thank them for spending their valuable time with you.
Let’s look at the technical questions now!

2). What are Connection Draining and Deregistration Delay in AWS Load Balancers?
Connection draining ensures that the connections established are allowed to finish before an instance is decommissioned or replaced within a load balancer. Connection draining is referred to as such for Classic Load Balancer (CLB). However, Application Load Balancer (ALB) and Network Load Balancer (NLB) have a similar feature referred to as Deregistration Delay.
3). What is a Stateful and Stateless Firewall?
- Stateful Firewall maintains the state of defined rules. Based on the defined inbound rules, it lets the outbound rules flow. Stateful firewalls can monitor and detect the states of all traffic on a network in order to track and defend against traffic patterns and flows.
- A stateless Firewall needs explicitly defined rules for inbound and outbound traffic. Stateless firewalls are intended to protect networks using static information such as source and destination addresses.
4). What is Power User Access in AWS?
The Power User Access role lets users create, configure, and manage AWS resources. Users having PowerUserAccess permissions do not have any control over IAM users, IAM groups, IAM roles, and permissions. The policy grants users access to AWS services and restricts identity and access management.
5). What are an Instance Store Volume and an EBS Volume?
- Instance Store Volume is temporary storage to store temporary data by an instance to a function.
- EBS Volume is a persistent storage disk that is available even when the instances are turned off.
6). What are the Recovery Time Objective and Recovery Point Objective?
- The Recovery Time Objective is the maximum delay that is acceptable between the interruption and restoration of service.
- Recovery Point Objective is the maximum delay that is acceptable since the last data restore point.
7). What is the way to upload a file that is greater than 100 MB in Amazon S3?
To upload a file greater than 100 MB on Amazon S3, use Multipart Upload Utility from AWS. It helps in uploading large files independently in multiple parts, and the upload time can be decreased by uploading parallelly.
8). What are DDoS attacks, and What Services can minimize them?
DDoS or Distributed Denial of Service is a cyber attack that disrupts the normal traffic to a web property. It attacks online services and websites by giving them more traffic than they can handle. The AWS Shield is a managed service for DDoS protection.
9). How does AWS ensure data security and compliance?
AWS provides multiple security features and compliance programs to ensure the security of customer data. These include security controls, compliance certifications, attestations, and a shared security responsibility model.
10). How does AWS handle scalability and elasticity for its customers?
AWS provides automatic scalability and elasticity to its customers through the use of services such as Auto Scaling and Elastic Load Balancing. These services allow customers to automatically increase or decrease the number of resources they are using based on demand.
11). Can you explain the concept of “hybrid cloud” and how it relates to AWS?
“Hybrid cloud” refers to the use of a combination of on-premises, private cloud, and public cloud services to meet the specific needs of an organization. AWS offers services such as AWS Direct Connect and AWS VPN to facilitate hybrid cloud deployments.
12). What are some Security Best Practices for Amazon EC2?
Security best practices for Amazon EC2 are:
- Only allowing the trusted hosts or networks to access ports on an instance.
- Using Identity and Access Management (Identity and Access Management) to control access to AWS resources.
- Only enabling those permissions you require and disabling password-based logins for instances launched from your AMI.
13). Differentiate between Stopping and Terminating an EC2 Instance.
In case of stopping an EC2 instance, there will be a proper shutdown of the instance. In case of terminating an EC2 instance, the instance will be permanently deleted and cannot be used again. The EBS volumes that were attached to the instance will be deleted according to the DeleteOnTermination parameter set for the volume.
14). What are the factors to consider while Migrating to AWS?
Considered factors while migrating to AWS are:
- Operational Costs
- Workforce Productivity
- Cost avoidance
- Operational resilience
- Business agility
15). How does AWS handle disaster recovery and business continuity?
AWS provides various disaster recovery and business continuity solutions such as AWS Backup, AWS Snowball, and AWS Snow Family, that allow customers to create copies of their data in multiple locations for disaster recovery and business continuity.
16). What is the difference between an IAM role and an IAM user?
Q17). What are the different uses of the various load balancers in AWS Elastic Load Balancing?
- Application Load Balancer – Used if you need flexible application management and TLS termination.
- Network Load Balancer – Used if you require extreme performance and static IPs for your applications.
- Gateway Load Balancer – Gateway Load Balancer helps you easily deploy, scale, and manage your third-party virtual appliances.
Q18). What distinguishes AWS CloudFormation from AWS Elastic Beanstalk?
Here are some differences between AWS CloudFormation and AWS Elastic Beanstalk:
- AWS CloudFormation assists you in provisioning and describing all infrastructure resources in your cloud environment. AWS Elastic Beanstalk, on the other hand, provides an environment that makes it simple to deploy and run cloud applications.
- AWS CloudFormation meets the infrastructure requirements of a wide range of applications, including legacy applications and existing enterprise applications. AWS Elastic Beanstalk, on the other hand, is integrated with developer tools to assist you in managing the lifespan of your applications.
Q19). How does Amazon Route 53 provide high availability and low latency?
Here’s how Amazon Route 53 provides the resources in question:
- Globally distributed servers – Amazon is a global service and consequently has DNS services globally. Any customer creating a query from any part of the world gets to reach a DNS server local to them that provides low latency.
- Dependency – Route 53 provides a high level of dependability required by important applications
- Optimal locations – Route 53 uses a global anycast network to automatically answer queries from the optimal location.
Q20). You’re working on a project that necessitates high availability and fault tolerance. How would you construct the AWS infrastructure to fulfill these objectives?
I would leverage AWS services such as Auto Scaling, Elastic Load Balancing, and Amazon RDS Multi-AZ deployments to ensure high availability and fault tolerance. To provide redundancy and reduce downtime, I would deploy the application across many Availability Zones (AZs). I would also utilize Amazon CloudWatch to monitor the application’s health and initiate automated scaling events based on predetermined thresholds.
Q21). Your web application must handle abrupt spikes in traffic during specified events. How would you design the AWS application architecture to deal with scalability and assure peak performance during these events?
I would construct the application to leverage Amazon Elastic Compute Cloud (EC2) instances in an Auto Scaling group to handle abrupt traffic spikes. I’d set up the Auto Scaling group to scale out based on measures like CPU consumption or network traffic. In addition, I would use Amazon CloudFront, a content delivery network (CDN), to cache and provide static content, which would reduce the burden on the application servers. As a result, the application can scale horizontally and efficiently manage additional traffic.
Q22). A customer wants to build a disaster recovery plan for its AWS-hosted critical systems. What business continuity strategies and services would you recommend?
To ensure business continuity and implement a disaster recovery plan, I would recommend using services like AWS CloudFormation for infrastructure provisioning and AWS CloudWatch for monitoring. I would utilize Amazon S3 for data backup and versioning, and leverage AWS Elastic Beanstalk or AWS Lambda to deploy and run the application in multiple AWS regions for redundancy. Additionally, I would enable cross-region replication for critical databases using services like Amazon RDS Multi-AZ or Amazon Aurora Global Database.
Q23). You’ve been tasked with lowering the cost of an AWS infrastructure. What steps would you take to find cost-cutting opportunities and cut costs?
To reduce expenses in an AWS environment, I would first analyze resource utilization using AWS Cost Explorer reports and AWS Trusted Advisor recommendations. To match resource requirements with actual usage, I would discover underutilized instances and rightsizing opportunities. I would also use AWS Lambda and Amazon S3 for serverless computation and storage, removing the requirement to manage and maintain dedicated resources. Costs can be reduced further by implementing scheduled instance shutdowns or employing AWS Spot Instances for non-critical applications.
Q24). A corporation wants to store sensitive data in AWS in a secure manner. How would you construct a system that maintains data confidentiality and integrity?
To manage encryption keys for data at rest and in transit, I prefer AWS Key Management Service (KMS). I would encrypt sensitive data via AWS Encryption SDK or the native encryption capabilities of AWS services such as Amazon S3, Amazon RDS, or Amazon EBS. In addition, I would use AWS Identity and Access Management (IAM) to enforce rigorous access restrictions and network security mechanisms such as VPCs, Security Groups, and Network ACLs to limit who may access the data and secure data in transit.
