Top AWS Interview Questions for Freshers Flashcards
This section covers some of the most common AWS interview questions and answers for freshers who intend to start their career in Amazon Web Services. These are the basic AWS interview questions that may be asked in an AWS interview whether the candidate be a fresher or an experienced.
Define Amazon Web Services or AWS.
This is one of the most basic AWS interview questions and can be answered in both simple and complex structures, depending on the interviewer.
According to the terminology, AWS or Amazon Web Services is defined as a platform which is designed to provide secure cloud services, computing power to clients, database storage options, content delivery and many other services which are all intended towards business development and growth.
List out the main components of AWS.
Similar to other Cloud Services in the industry, AWS too has been designed in a structured manner and has several key components. Mentioned below is the list of the same:
Amazon Route 53: This is a DNS (Domain Name Service) web service.
Easy Email Service: This service allows customers and clients to address email utilization through normal SMTP or RESTFUL API.
Access Management and Identity: This has been designed in order to provide heightened identity control and protection for a client’s AWS account.
S3 or Simple Storage Device: It is a very well-known utility among all the AWS Services and is mainly used in warehouse equipment.
EC2 or Elastic Compute Cloud: This is a utility designed to manage variable workloads and gives clients the ability to afford on-demand computing sources for hosting.
EBS or Elastic Block Store: This particular utility is used to expand beyond EC2 and is designed to connect EC2 to enable the lifespan of data beyond the capacities of EC2.
Cloud Watch: This is mainly a crisis management utility and is designed to help managers inspect and obtain additional resources in the light of a crisis.
What do you know about Buffer in AWS?
A buffer is necessary in any cloud computing technology in order to maintain seamless integration across a huge flow of traffic and loads. The Elastic Load Balancer in Amazon Web Services has been designed in a way to ensure that all the incoming traffic is optimally distributed across all channels of AWS instances.
The presence of a buffer enables the components to work in an unstable situation and receive and process requests as it gets them. Essentially the presence of a buffer is needed to create an equilibrium between all the apparatus and provide them with an identical ability to supply more rapid services.
How can you secure your data in the cloud?
One of the most important aspects of cloud computing is its security. It must be ensured at all times that no individual or organization is able to seize the data of a client while in a transition from one point to another and also there shouldn’t be any leakage of information from any of the several storerooms in the cloud. Thus one of the most effective ways of securing information is by segregating it and then encrypting the same by one of the mutually agreed options.
List out the different services offered by cloud computing.
There have been a number of public and private cloud platforms developed these days. All of these are composed of several services/layers of cloud computing. Mentioned below is a list of the same:
PaaS: It is the acronym for Platform as a Service.
IaaS: It is the acronym for Infrastructure as a Service.
SaaS: It is the acronym for Software as a Service.

Can Amazon Instance be vertically scaled? If yes, how?
Yes, it is very much possible to vertically scale an Amazon Instance. Here’s how:
- Form and twist a fresh massive instance on top of the currently governing instance.
- Make an attempt to delay the current instance and separate the source web mass of dispatch and server.
- The next step is to quit your existing instance and separate the same from source quantity.
- Take note of the new machine ID and connect the same source mass to your fresh server.

Name the basic components of Amazon Web Services.
Amazon Web Services or AWS consists of 4 main components that are as listed below:
Amazon S3: This component has been designed to enable one to retrieve information which has been occupied in creating the cloud structural design and also retrieve the produced information as a consequence of the specified key.
Amazon EC2 instance: This component has been designed in order to run automatic parallelization and also achieve job scheduling. This instance is immensely helpful in running a large distributed system on the Hadoop Cluster.
Amazon SimpleDB: This component helps in the storage of the transitional positional log and also run the errands when they are executed by the client or the consumer.
Amazon SQS: This component has been mainly designed to act as a mediator between different controllers. This is an additional cushioning for the managers at Amazon.
