A company is implementing a new business application. The application runs on two Amazon EC2 instances and uses an Amazon S3 bucket for document storage. A solutions architect needs to ensure that the EC2 instances can access the S3 bucket.What should the solutions architect do to meet this requirement?
Answer(s): A
A) A is correct because attaching an IAM role to EC2 instances provides temporary credentials via instance metadata, enabling Secure S3 access without embedded keys. Roles are the recommended method for EC2 access to AWS services.B) Attaching an IAM policy directly to EC2 is invalid; policies grant permissions to principals (users, roles, groups), not to compute resources. You must attach a role (or user) with the policy.C) IAM groups are for users, not for EC2 instances; there is no mechanism to attach a group to an EC2 instance.D) IAM users are long-term credentials unsuitable for EC2 without rotating access keys; embedding user credentials is insecure. Roles are preferred.
An application development team is designing a microservice that will convert large images to smaller, compressed images. When a user uploads an image through the web interface, the microservice should store the image in an Amazon S3 bucket, process and compress the image with an AWS Lambda function, and store the image in its compressed form in a different S3 bucket.A solutions architect needs to design a solution that uses durable, stateless components to process the images automatically.Which combination of actions will meet these requirements? (Choose two.)
Answer(s): A,B
The correct options A and B implement a durable, stateless, event-driven flow using S3 to trigger SQS and Lambda to process and store results without servers.A) S3 event to SQS decouples uploader from processing and provides durable, retriable messaging for Lambda. B) Lambda consuming from SQS ensures automatic scaling, stateless processing, and proper message deletion after success.C) Not stateless or durable (in-memory tracking) and misses event-driven reliability. D) EC2 introduces stateful management and server provisioning, breaking durability and scalability. E) SNS alerting is not a processing trigger or durable workflow for image transformation.
A company has a three-tier web application that is deployed on AWS. The web servers are deployed in a public subnet in a VPC. The application servers and database servers are deployed in private subnets in the same VPC. The company has deployed a third-party virtual firewall appliance from AWS Marketplace in an inspection VPC. The appliance is configured with an IP interface that can accept IP packets.A solutions architect needs to integrate the web application with the appliance to inspect all traffic to the application before the traffic reaches the web server.Which solution will meet these requirements with the LEAST operational overhead?
Answer(s): D
Gateway Load Balancer (GWLB) with a GWLB endpoint provides transparent, scalable traffic steering to the inline inspection appliance in an inspection VPC, allowing all traffic to be inspected before reaching the web tier with minimal operational overhead. It supports autoscaling and preserves source IP, and integrates with third-party appliances via standard inline networking.A) NLB would route at layer 4 but not provide built-in integration with a centralized inline appliance in a separate inspection VPC.B) ALB is application-layer and not suitable for transparent inline inspection of all traffic to the web tier.C) Transit Gateway adds complexity and does not inherently provide inline inspection with a dedicated appliance endpoint.
A company wants to improve its ability to clone large amounts of production data into a test environment in the same AWS Region. The data is stored in Amazon EC2 instances on Amazon Elastic Block Store (Amazon EBS) volumes. Modifications to the cloned data must not affect the production environment. The software that accesses this data requires consistently high I/O performance.A solutions architect needs to minimize the time that is required to clone the production data into the test environment.Which solution will meet these requirements?
The correct answer D is right because EBS Fast Snapshot Restore pre-wills data to SSD storage, allowing immediate high IOPS-attached volumes in the test environment after restoring from snapshots, meeting the isolation and performance requirements and minimizing clone time.A is incorrect because restoring to instance store volumes loses EBS durability and requires rebuilding; not suitable for high I/O or consistent production data cloning.B is incorrect because Multi-Attach is for attaching a single volume to multiple instances for shared access, not for isolating test data; it risks data corruption when the production volume is modified.C is incorrect because restoring from snapshots to new volumes is valid but slower without Fast Snapshot Restore; it increases clone time.
An ecommerce company wants to launch a one-deal-a-day website on AWS. Each day will feature exactly one product on sale for a period of 24 hours. The company wants to be able to handle millions of requests each hour with millisecond latency during peak hours.Which solution will meet these requirements with the LEAST operational overhead?
A concise justification:D) Uses S3 for static content with CloudFront, plus API Gateway and Lambda for backend, and DynamoDB for scalable, low-latency data storage. This serverless approach minimizes operational overhead, scales to millions of requests per hour with millisecond latency, and avoids provisioning/manage servers or clusters.A) S3 with CloudFront alone handles static content and low-latency delivery but lacks a scalable, serverless backend and suitable data store for dynamic order data.B) EC2 Auto Scaling with ALB incurs more operational effort and management; scaling the backend and database is heavier.C) EKS with Cluster Autoscaler adds Kubernetes management complexity; still requires relational DB and more maintenance.
A solutions architect is using Amazon S3 to design the storage architecture of a new digital media application. The media files must be resilient to the loss of an Availability Zone. Some files are accessed frequently while other files are rarely accessed in an unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files.Which storage option meets these requirements?
Answer(s): B
S3 Intelligent-Tiering automatically moves objects between frequent and infrequent access tiers based on usage, minimizing cost while providing the same-namespace resilience and durability as S3, including across AZs. A) S3 Standard is durable and highly available but not cost-optimized for unpredictable access patterns. C) S3 Standard-IA lowers storage cost but incurs retrieval fees and does not optimize for unpredictable access automatically. D) S3 One Zone-IA stores data in a single AZ, reducing durability resilience to AZ loss, which contradicts the requirement. B) correctly balances cost across access patterns and preserves data across AZs without manual tiering.
A company is storing backup files by using Amazon S3 Standard storage. The files are accessed frequently for 1 month. However, the files are not accessed after 1 month. The company must keep the files indefinitely.Which storage solution will meet these requirements MOST cost-effectively?
S3 Glacier Deep Archive is the lowest-cost storage for long-term data that is rarely accessed, making B cost-optimal for keeping backups indefinitely after an initial month of frequent access.A) S3 Intelligent-Tiering adds monitoring costs and may still tier to frequent access tiers; not as cost-effective for long-term retention with no access. B) Correct: transitions after 1 month to Glacier Deep Archive minimizes storage cost while preserving access if needed in future. C) S3 Standard-IA incurs retrieval costs and higher per-GB price than Glacier Deep Archive for long-term, infrequently accessed data. D) One Zone-IA stores data in a single AZ and has higher risk of data loss and higher retrieval costs relative to Glacier Deep Archive for immutable backups.
A company observes an increase in Amazon EC2 costs in its most recent bill. The billing team notices unwanted vertical scaling of instance types for a couple of EC2 instances. A solutions architect needs to create a graph comparing the last 2 months of EC2 costs and perform an in-depth analysis to identify the root cause of the vertical scaling.How should the solutions architect generate the information with the LEAST operational overhead?
The correct answer is B. Cost Explorer’s granular filtering allows you to drill down EC2 costs by instance type, over a two-month window, enabling fast, insight-driven root-cause analysis with minimal setup and operational overhead.A) AWS Budgets focuses on cost thresholds and alerts, not in-depth per-instance-type cost analysis.C) Billing dashboard graphs offer basic visuals but lack the granular, customizable filters needed for root-cause analysis by instance type and time range.D) Cost and Usage Reports with QuickSight provides full analytics but involves additional data processing and setup, increasing overhead.

easy questions
q.189 - answers are incorrect.
question 8 - can cloudtrail be used for storing jobs? based on aws - aws cloudtrail is used for governance, compliance and investigating api usage across all of our aws accounts. every action that is taken by a user or script is an api call so this is logged to [aws] cloudtrail. something seems incorrect here.
thanks for the questions
this is very helpfull for me
this is a good experience
q. 289 - the correct answer should be b not d, since the question asks for the most secure way to provide access to a s3 bucket (a single one), and by principle of the least privilege you should not be giving access to all buckets.
i took the aws saa-c03 test and scored 935/1000. it has all the exam dumps and important info.
is it possible to clear the exam if we focus on only these 156 questions instead of 623 questions? kindly help!
great job. hope this helps out.
