Certified Exam Cards: AWS Certified
Solutions Architect- Latest Question and
Answers [100% Correct] 2025
What are the main benefits of using Amazon Web Services (AWS) over traditional on-premises
infrastructure?

AWS offers scalability, flexibility, cost-efficiency, and a broad set of services compared to
traditional infrastructure. It allows businesses to pay only for what they use and scale resources up or
down based on demand.



How does AWS ensure high availability for applications deployed in the cloud?

AWS provides high availability through multiple Availability Zones (AZs) within regions, offering
redundancy and fault tolerance. Services like Elastic Load Balancer (ELB) and Auto Scaling also help
distribute traffic and scale resources to ensure application uptime.



What is the difference between Amazon EC2 and AWS Lambda?

Amazon EC2 is a virtual machine that provides full control over the computing environment, while
AWS Lambda is a serverless compute service that automatically runs code in response to events without
the need to manage servers.



How can you secure access to AWS resources?

AWS resources can be secured using IAM (Identity and Access Management) to control user
access with permissions, MFA (Multi-Factor Authentication) for extra security, and encryption for data
protection both in transit and at rest.



What is Amazon VPC, and how is it used in AWS?

Amazon Virtual Private Cloud (VPC) is a private network within AWS that allows you to isolate
resources, control traffic flow, and define security parameters for your cloud resources, enabling a secure
and customizable network architecture.



What is the difference between S3 and EBS in AWS?



1

, Amazon S3 (Simple Storage Service) is an object storage service designed for scalable and durable
data storage, while Amazon EBS (Elastic Block Store) provides persistent block-level storage for use with
EC2 instances.



Explain the concept of Auto Scaling in AWS.

Auto Scaling automatically adjusts the number of EC2 instances in response to traffic demands. It
ensures that an application has the right amount of compute capacity based on predefined scaling
policies and metrics such as CPU utilization.



What is AWS CloudFormation and how does it help with infrastructure management?

AWS CloudFormation allows you to define infrastructure as code, enabling automated and
consistent provisioning of resources. It helps in creating, updating, and managing AWS resources using
templates that describe the desired infrastructure.



What are the advantages of using Amazon RDS over self-managed databases?

Amazon RDS (Relational Database Service) simplifies database management by automating tasks
like backups, patching, scaling, and high availability, reducing operational overhead compared to self-
managed databases.



How does AWS handle data backup and recovery?

AWS offers various backup solutions such as Amazon S3 for object storage, Amazon EBS snapshots
for block-level data, and AWS Backup for centralized backup management, ensuring data recovery in the
event of failure.



What is AWS Elastic Beanstalk, and how is it used?

AWS Elastic Beanstalk is a platform-as-a-service (PaaS) that simplifies the deployment,
management, and scaling of applications by automatically handling infrastructure provisioning, load
balancing, and scaling.



How can you monitor AWS resources and applications?

AWS provides monitoring tools like Amazon CloudWatch for tracking metrics, logs, and
performance data of resources, AWS X-Ray for tracing applications, and AWS CloudTrail for logging API
calls made across the AWS infrastructure.


2

, What is Amazon CloudFront and how is it used for content delivery?

Amazon CloudFront is a Content Delivery Network (CDN) that distributes content globally, caching
data at edge locations to reduce latency and improve performance for users accessing websites,
applications, and media content.



What is AWS Direct Connect, and how does it enhance network connectivity?

AWS Direct Connect allows you to establish a dedicated, private connection from your on-
premises infrastructure to AWS, reducing bandwidth costs and increasing network performance by
bypassing the public internet.



What is the purpose of AWS IAM roles?

IAM roles are used to delegate access to AWS resources for users, applications, or services. They
define a set of permissions that can be assumed by entities to access specific AWS resources securely.



How does AWS manage serverless computing with Lambda?

AWS Lambda is a serverless computing service that automatically executes code in response to
events. Users don't need to provision or manage servers, making it highly scalable and cost-efficient for
event-driven applications.



What are the primary types of storage available in AWS?

AWS offers several storage options, including Amazon S3 for object storage, Amazon EBS for block
storage, Amazon Glacier for archival storage, and Amazon FSx for file storage, catering to various use
cases and performance requirements.



What is Amazon Route 53, and how is it used in AWS?

Amazon Route 53 is a scalable DNS (Domain Name System) service that provides domain
registration, routing internet traffic to resources, and managing DNS records to ensure high availability
and reliability for web applications.



How does AWS handle data encryption and security?
