A company uses NFS to store large video files in on-premises network attached storage. Each video file ranges in size from 1 MB to 500 GB. The total storage is 70 TB and is no longer growing. The company decides to migrate the video files to Amazon S3. The company must migrate the video files as soon as possible while using the least possible network bandwidth.Which solution will meet these requirements?
Answer(s): B
Using Snowball Edge (B) minimizes network bandwidth and provides the fastest offline transfer for 70 TB of on-prem data, with AWS handling import to S3 after physical shipment. It is cost- and time-efficient for large-scale migration and avoids saturating production networks.A) Over the network via AWS CLI would consume significant bandwidth and time for 70 TB. C) S3 File Gateway introduces extra latency and uses network transfer over NFS to S3, not optimized for bulk offline shipment. D) Requires a Direct Connect link and still uses network transfer; adds unnecessary complexity for a one-time large data transfer.
A company has an application that ingests incoming messages. Dozens of other applications and microservices then quickly consume these messages. The number of messages varies drastically and sometimes increases suddenly to 100,000 each second. The company wants to decouple the solution and increase scalability.Which solution meets these requirements?
Answer(s): D
D) Using SNS with multiple SQS subscriptions decouples producers from consumers, providing fan-out, scalable, event-driven messaging that handles burst traffic and ensures durable, decoupled processing. SNS distributes messages to multiple SQS queues, enabling independent scaling of each consumer, buffering, and retry handling.A) Kinesis Data Analytics is for real-time analytics on streams, not decoupling or fan-out to multiple independent consumers as required.B) EC2 Auto Scaling loses the managed, event-driven decoupling and requires handling of scaling logic and backpressure externally.C) Kinesis Data Streams with a single shard limits throughput; DynamoDB introduces additional complexity and lacks built-in fan-out-to-multiple consumers with decoupled processing.
A company is migrating a distributed application to AWS. The application serves variable workloads. The legacy platform consists of a primary server that coordinates jobs across multiple compute nodes. The company wants to modernize the application with a solution that maximizes resiliency and scalability.How should a solutions architect design the architecture to meet these requirements?
A) Incorrect. SQS with EC2 ASG and scheduled scaling does not dynamically balance workload based on queue depth, reducing resiliency for variable workloads.B) Correct. SQS decouples jobs from workers; EC2 instances in an ASG scale based on queue length, providing elastic, fault-tolerant processing and automatic recovery.C) Incorrect. CloudTrail is an audit log service, not a destination for jobs; scaling based on primary server load lacks decoupling and can create bottlenecks.D) Incorrect. EventBridge/CloudWatch Events is for event routing, not a direct job destination; scaling on compute node load misses the queue-backed elasticity.
A company is running an SMB file server in its data center. The file server stores large files that are accessed frequently for the first few days after the files are created. After 7 days the files are rarely accessed.The total data size is increasing and is close to the company's total storage capacity. A solutions architect must increase the company's available storage space without losing low-latency access to the most recently accessed files. The solutions architect must also provide file lifecycle management to avoid future storage issues.Which solution will meet these requirements?
A short summary: Using a File Gateway with S3 storage and lifecycle policies best preserves low-latency access for recent files while expanding capacity and managing data aging.A) Incorrect. DataSync moves data, but does not provide continuous access to recent files on-premises and lacks integrated lifecycle management for ongoing growth.B) Correct. S3 File Gateway extends on-premises storage with S3, preserving low-latency access for recent files via local cache, while S3 Lifecycle moves older data to Glacier Deep Archive to free space.C) Incorrect. FSx for Windows provides additional Windows file storage but does not inherently integrate with on-prem SMB access or lifecycle tiers to archive data.D) Incorrect. Client-side S3 access with lifecycle to Glacier Flexible Retrieval reduces performance and does not maintain local low-latency access for active files.
A company is building an ecommerce web application on AWS. The application sends information about new orders to an Amazon API Gateway REST API to process. The company wants to ensure that orders are processed in the order that they are received.Which solution will meet these requirements?
Using an API Gateway integration to place each new order into an SQS FIFO queue ensures strict message ordering and at-least-once processing with exactly-once in-order semantics, which is appropriate for processing ecommerce orders in arrival order. The FIFO queue guarantees ordering via message group IDs and provides deduplication.A) SNS does not preserve per-message processing order across multiple subscribers; ordering is not guaranteed. C) API Gateway authorizers control access, not processing order. D) SQS standard queue does not guarantee strict ordering; messages can be delivered out of order.
