AWS Sysops Interview Questions for Freshers

1. Define AWS?

Amazon Web Services, or AWS, is a platform that offers secure cloud services, database storage, computing capacity, content distribution, and other services to support the growth and level of businesses.

2. How does buffer function within Amazon Web Services?

The distribution of incoming traffic among different Amazon instances is optimized thanks to an elastic load balancer. The setup will be elastic to a spike in traffic or load by synchronizing many components and using a buffer. The components tend to process and respond to queries inconsistently. To supply services rapidly, the buffer teaches various apparatus to function at the same pace and creates an equilibrium between them.

3. Describe the roles.

It grants permissions to entities in your AWS account that you may trust. It resembles users in many ways. Roles eliminate the need to create a username and password to access the resources.

4. What is the best way to protect data on the cloud?

Monitoring data as it travels from one location to another is the most effective method of data security. Security key leaks within the amount of the cloud storerooms need to be cautiously watched. separating the data and encrypting it using a recognized method is one of the best ways to prevent data theft. Data management in the cloud is incredibly secure thanks to Amazon Web Services.

5. What are the various cloud computing layers?

The list of cloud computing layers is as follows:

  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)
  • Software as a Service (SaaS)

6. What elements makeup Amazon Web Services?

As listed below, Amazon Web Services is made up of numerous Components:

  • Route 53: It is a basic DNS-based web service.
  • Amazon S3: With this component, crucial data that is required to build structural designs and other types of data is stored as a result of the key supplied.
  • Amazon EC2: This part functions effectively on a Hadoop Cluster’s huge distributed system. Parallelization operates automatically, and work schedules can be efficiently accomplished with this component. Moreover, it serves as a cushion as needed.
  • Amazon Simple DB: Saves the errors and transitional position records made by its users.
  • Cloudwatch: keeps an eye on Amazon Web Services assets and lets managers examine and gather keys.

7. Describe Edge locations.

Edge Location is the location where the contents will be cached. In this way, if a user tries to access any resource, the content will immediately be searched in the edge location.

8. How do you define VPC?

Virtual Private Cloud is a VPC. You can customize your networking configuration thanks to it. Another network in the cloud is segregated from this one. Your IP address range, internet gateways, subnet, and security groups are all possible with it.

9. What does SimpleDB mean?

The key value data store is another name for a simple database. Developers can request and store data using this highly accessible and versatile non-relational database with very little database maintenance and administrative work.

10. What kinds of virtualization does AWS support?

AWS supports three different types of virtualization: hardware virtual machines, paravirtualization, and paravirtualization in hardware virtual machines.

11. In CloudFront, what is geo-targeting?

For instance, if you want your company to create and present tailored information to the audience depending on their geographic location without altering the URL, then use geo-targeting. By prioritizing individual demands, geo-targeting helps one create tailored content for a group of viewers in a particular geographic location.

12. What is a snowball, exactly?

A data transfer option is snowball. A lot of data is moved into and out of AWS using source appliances. It makes it possible to send enormous amounts of data back and forth. It reduces the cost of networking.

13. What distinguishes flexibility from scalability?

Scalability is the ability to improve performance to finish the tasks at hand with the resources available, whereas flexibility is the ability of the system to operate at its full potential. In addition to being adaptable, Amazon Web Services may extend its services as needed by enhancing its auxiliary hardware properties.

14. List all of the layers in a cloud architecture.

  1. Cluster Controller (CC)
  2. Storage Controller
  3. Cloud Controller (CLC)
  4. Walrus
  5. Node Controller in NIC


15. What do you understand by auto-scaling?

One of Amazon Web Services’ most impressive capabilities is its ability to automatically arrange, define, and generate new problem-solving techniques without your assistance. Setting the metrics and bounds on a watch will enable this.

16. Which automatic gears assist us in providing spinup services?

Services are spun up using API tools that are typically used to write scripts. They can be programmed in Perl, Bash, or any other preferred language. Together with controlled tools like RightScale, other tools like Scalr are also used.

17. How may a vertical scale be applied to an Amazon instance?

It is among Amazon Web Services’ most reliable qualities. The final line of defense needs to be a spinup. The root EBS volume should be divided, expanded, and taken off of this server. The system should be restarted after recording the distinctive device ID and adding it to the new server. In Amazon Web Services, this is the most effective way to scale up vertically.

18. How can you use the Amazon EC2 service?

You can launch as many virtual services as you need using the Amazon Elastic Compute Cloud (EC2) service, which offers scalable computing services on the cloud.

19. What characteristics do Amazon EC2 Services have?

It has these characteristics:

  • Environments for Virtual Computing
  • Templates that are already set up for instances
  • AMI-formatted complete packages are required for the server.
  • Using key pairs, secure login information for instances
  • When instances are terminated, storage volumes containing temporary data are removed.
  • Persistent storage volumes are offered.
  • a firewall that allows you to choose the protocol
  • Elastic IPs, a static IP address for dynamic cloud computing

20. What connection exists between instances and AMI?

There are several ways to access Amazon EC2 through Amazon Web Services, including a web-based interface, a command-line interface, and Amazon tools for Windows Powershell. To access this, one must create an Amazon Web Services account.

21. How does storage work with Amazon EC2 instances?

There are four alternatives for data storage offered by Amazon EC2 based on its performance and durability.

  • The running life of the instance is unrelated to the Amazon EBS data storage volume. Accessing an external hard drive in the cloud is analogous to doing so.
  • The storage volume that is connected to the host computer is called an Amazon EC2 Instance store. If you terminate the instance, the data on the instance store is permanently deleted and is only accessible for the duration of the instance.
  • Amazon S3 is the most dependable and affordable choice for accessing and changing data at any time, anywhere.
  • Adding storage – A root storage device is established for each instance when it is launched.

22. Describe how to use the Amazon Web Services Model to simulate perimeter security.

When we first recognized the necessity for security systems, firewalls have been utilized as the first line of protection in traditional perimeter security, as we are all aware. Previous techniques are no longer supported by Amazon Web Services or Amazon EC2 and have become dated. Security groups are preferred and supported by Amazon. For a jump box with ssh access, a security group can be made. A webserver and database group can then be built from there. The webserver group can then be expanded to include the specified number of servers, and they will all take care of the database.

23. How do I use Amazon SQS?

The Amazon Simple Queue service is a message-passing system used to communicate between several connections that are connected. Also, it facilitates communication between every element of the Amazon web services, keeping every functional element together.

AWS Sysops Administrator Interview Questions with 3 years of experience

1. What function does buffer play in Amazon Web Services?

The distribution of incoming traffic among different Amazon instances is optimized thanks to an elastic load balancer. Several components will be synchronized via a buffer, making the arrangement adaptable to a spike in traffic or load. The components tend to process and respond to queries inconsistently. To supply services more rapidly, the buffer teaches various apparatus to function at the same pace and creates an equilibrium between them.

2. Why are subnets created?

Subnets can be used to split up a big network into smaller ones. These subnets should be constructed for a variety of reasons. The construction and use of subnets, for instance, can help to lessen congestion by ensuring that traffic meant for a subnet stays in that subnet. Successfully directing traffic entering the network, helps to lighten the load on the network.

3. Is it possible to upload a file to Amazon S3 that is bigger than 100 megabytes?

Sure, you may do it by utilizing AWS’s multipart upload tool. The multipart upload tool can be used to upload larger files in multiple, independent pieces. You can expedite the upload process by uploading these parts all at once. Once the pieces have been uploaded and assembled into a single object or file, the original file from whence they were made will be created.

4. How many S3 buckets can you create at one time?

There can be a maximum of 100 S3 buckets generated.

5. On an EBS-backed machine, how can the data on the root disc be saved?

By overriding the terminate option, we can store the data.

6. When should you utilize the classic load balancer and the application load balancer?

For easy traffic load balancing across numerous EC2 instances, the traditional load balancer is utilized. While the usage of application load balancing, depending on the multi-tier architecture or container-based architecture of the application, allows for more intelligent load balancing. The majority of the time, application load balancing is utilized to send traffic to several services.

7. How many subnets per VPC and total VPCs per account/region are allowed?

For every account/region, we are permitted a maximum of five VPCs and 200 subnets.

8. Your company has decided to move all of its workloads to a public cloud. Yet, your company decides to divide some of the burdens on private servers due to some security concerns. You are required to recommend a cloud architecture for your company. What will you recommend?

A hybrid cloud. In a hybrid cloud architecture, a company can use the private cloud for its secret workloads while using the public cloud for shared resources.

9. Which Amazon storage option would you choose if you required extremely low price and data archiving?

Data preservation and backup are accomplished using AWS Glacier, a remarkably inexpensive storage solution provided by Amazon. The cost of storing data in Glacier decreases over time.


10. The information on an instance’s root volumes is automatically deleted when the instance with store-backed or EBS-backed storage is terminated. How would you stop that from happening, and in which instance?

Instances with EBS backing. The root volume for EBS-backed instances is an EBS volume. Snapshots are an efficient way to quickly back up and copy the virtual drives that make up an EBS volume. The ability to configure the data to be maintained for later retrieval even if the virtual machine or instances are terminated is the main advantage of EBS-backed volumes.

11. How should an Amazon S3 bucket be set up to provide static files for your open-source web application?

By setting the bucket policy so that all objects have public read access.

12. Will your standby RDS be launched in the same availability zone as your primary if you do so?

No, standby infrastructures are launched automatically in a distinct availability zone from the primary, allowing for physical independence. This is true because the main purpose of backup instances is to prevent infrastructure failure. So, the standby instance will aid in data recovery if the primary instance fails.

13. Your business wishes to use its email address and domain to communicate with its clients about compliance. What service do you recommend using to accomplish the same goal quickly and affordably?

Amazon Simple Email Service (Amazon SES), a cloud-based email-sending service, can be used to achieve this.

14. Which Amazon service will you employ if you want to speed up the transfer of petabytes of data between AWS and storage devices while maintaining data security?

Amazon Snowball. For massive amounts of data that need to be transported into and out of Amazon utilizing physical storage devices, AWS Snowball is the solution.

15. Can you use standby DB instances in addition to your primary DB instance if you are running your DB instance as a Multi-AZ deployment?

The standby DB instance cannot be used concurrently with the primary DB instances since they are intended to be utilized if the primary instance fails.

16. With AWS, your company is creating a brand-new multi-tier web application. There is a small, new organization with few employees. Nonetheless, the company needs high availability. Table joins and sophisticated queries are features of this new application. Which Amazon service will be the ideal answer for your company’s needs?

Since DynamoDB is intended to be highly scalable, more so than RDS or any other relational database server, it will be the best option in this situation.

17. Accidentally, you terminated an EC2 instance in a VPC that had an Elastic IP assigned to it. What will happen if the instance is restarted?

Only if the instance is terminated will the elastic IP be cut off from it. No changes to the instance will result from stopping and starting it, and no data will be lost.

18. There are about 50 IAM users in your business. Now, it wants to introduce a new policy that will have an impact on an IAM user’s access rights. How can it accomplish this without having to apply the rule to every user individually?

By using Amazon IAM groups, including users in the groups according to their roles, and merely applying the policy to the groups, it is achievable.

19. I used autoscaling when I made a web application. I noticed that my application has the most traffic between the hours of 9 AM and 7 PM on Wednesdays and Fridays. What is the best way for me to deal with the scaling?

Set up an autoscaling policy to scale following predictable traffic patterns.

20. Given that the replica RDS instance is not promoted as the master instance, how would you respond if the relational database engine frequently crashed whenever your RDS instances increase in traffic?

For handling high volumes of traffic and producing manual or automatic snapshots to restore data if the RDS instance fails, a larger RDS instance type must be used.

21. Your Amazon EC2 instance is executing an application. As soon as your instance’s CPU use exceeds 100%, you should lessen the strain on it. How will you carry that out?

It can be done by building an autoscaling group to deploy extra instances when the CPU utilization surpasses 100% and by creating a load balancer and registering the Amazon EC2 instances with it to distribute traffic among instances.

22. How would I go about accessing Amazon Simple Storage buckets so that I could use the data for access audits?

As AWS CloudTrail is intended for logging and tracking API calls and is also available for storage solutions, it can be used in this situation.

23. To encrypt my data in the Oregon region, I produced a key in the North Virginia region. I also created an extra AWS account and three additional users to the key. Then, when I attempted to use the same key to encrypt an object in S3, it was not present. Where did I make a mistake?

The key and the data ought to be in the same location. In other words, the data that has to be encrypted should be at the same location as the key’s creation. The data in this instance is from the Oregon region, although the key was made in North Virginia.

24. Consider hosting an application on AWS that allows users to display graphics and perform other typical computing tasks. Which of the services listed below can you utilize to direct incoming user traffic?
Network Load balancer

Application Load Balancer
Classic Load Balancer

Application Load Balancer: It allows for path-based traffic routing, which improves the performance of applications divided into smaller services. Traffic can be routed using an application load balancer according to the requests made. In this instance, traffic where requests for rendering images can be routed to servers only set up for rendering images, and traffic where requests for computing can be directed to servers only set up for general computing.

25. Let’s say I set up a subnet and started an EC2 instance in it using the default configuration. Which of the above choices will be available for use on the EC2 instant it is launched?
Public IP

Elastic IP
Private IP
Internet Gateway

Private IP. The instance is launched with a private IP automatically assigned. Since Public IP requires an Internet Gateway, which must also be built since it is a new VPC, Elastic IP must be explicitly configured.

AWS Sysops Administrator Interview Questions with 5 years of experience

1. Which Amazon service will you pick if you wish to gather and prepare e-commerce data for analysis in close to real-time? (Choose any two)

DynamoDB. Every kind of unstructured data can be fed into DynamoDB, a fully managed NoSQL database service. DynamoDB is the best option for gathering data from e-commerce websites. We can use Amazon Redshift for analysis that happens in real-time.

2. What will happen when a request is made for content that isn’t available at an edge location in CloudFront?

The content will be delivered via CloudFront straight from the origin server. Moreover, the content will be kept in the edge location’s cache since it was absent.

3. Is it possible to modify an EC2 instance’s private IP address when it is active or stopped?

No, you cannot modify it. A private IP address is given to each newly started EC2 instance at the moment of the boot. This private IP address is permanently assigned to the instance and cannot be modified.

4.If you need to transfer data from instances dispersed across international borders to your Amazon S3 bucket across a long distance utilizing the Internet, which of the following options will you choose?
M. Glacier

Kindle Snowball
Amazon Transfer Acceleration
Amazon CloudFront

Amazon Transfer Acceleration. Using Amazon Content Delivery Network and optimal network pathways reduces data transfer by up to 300 percent. Snowball cannot be utilized in this situation since it does not permit data transfer between regions.

5. Which of the following services employs secure HMAC-SHA1 authentication keys and includes a REST API interface for data storage?
Amazon S3

Amazon Snapshot
Elastic Block Shop on Amazon

An Amazon S3. It must decide which demands from various applications should be approved and which ones should be rejected. For request authentication, the Amazon S3 REST API employs a unique HTTP mechanism based on a keyed HMAC.

6. Is it possible to scale vertically in an Amazon instance?

Yeah, you can estimate one Amazon instance vertically.

7. How do lifecycle hooks in autoscaling work?

To add an extra wait time to a scale-in or scale-out event, autoscaling uses lifecycle hooks.

8. How are the different Cloud Architecture levels described in Amazon training?

The following are various cloud architecture layers:

  • Cluster controller
  • Cloud controller
  • Node Controller
  • Storage Controller


9. The information on an instance’s root volumes is automatically deleted when the instance with store-backed or EBS-backed storage is terminated. Which instance would you use to prevent that from happening? Ensure that the data or settings won’t be lost if the EC2 instance is restarted.

Examples of EBS EBS-backed volume or instances. The root volume for EBS-backed instances is an EBS volume. These volumes hold data, operating systems, and applications. We can create snapshots or an AMI using these volumes.

The ability to configure the data to be maintained for later retrieval even if the virtual machine or instances are terminated is the main advantage of an EBS-backed volume.

10. An EC2 instance hosting your application is active. Once the CPU usage on your instance hits 80%, you must lessen the load on it. How will you perform the job?

This can be done by setting up an autoscaling group to deploy new instances when an EC2 instance’s CPU usage exceeds 80%. Moreover, traffic can be distributed among instances by creating an application load balancer and designating EC2 instances as target instances.

11. A startup business has a web application running behind many Amazon EC2 instances behind an Application Load Balancer across multiple Availability Zones in the us-east-1 Region. The company needs a solution with reduced latency and enhanced high availability as its user base expands in the us-west-1 region. How can a solutions architect accomplish it?

You should take note of the fact that the web application is now located in the US-east-1 region, where the user base is expanding. The initial step is to set up an Application Load Balancer in us-west-1 and several EC2 instances (web application servers). Create a Global Accelerator using an endpoint group that contains the load balancer endpoints from both Regions in AWS Global Accelerator.

12. A business already runs a web application that is supported by an Amazon RDS MySQL database. It has daily automated backups that are not encrypted. Future backups must be encrypted, and unencrypted backups must be deleted to pass a security audit. Before eradicating the previous backups, the business will create at least one encrypted backup. How can encryption be enabled for upcoming backups?

  • Take a snapshot of the database.
  • Transfer it to a protected snapshot.
  • Use the encrypted snapshot to restore the database.

13. A company’s online application uses numerous Linux Amazon EC2 instances and Amazon EBS volumes to store data. The company is trying to find a solution to offer storage that satisfies the requirements for atomicity, consistency, isolation, and durability while enhancing the application’s resilience in the case of a malfunction (ACID). How should a solutions architect proceed to satisfy these requirements?

An application load balancer that spans many availability zones can be built using Amazon Auto Scaling groups. Each instance should mount a target and save data to Amazon EFS.

14. According to a client, they requested to view an audit log of any modifications made to the Amazon resources in their account. What steps may the client take to fulfill this?

Enabling the delivery of AWS CloudTrail logs to an Amazon S3 bucket.
