Amazon AWS Certified Solutions Architect - Associate SAA-C03 Bundle

The option Bundle or optimize static assets and use HTTP compression where appropriate addresses a separate condition: a site contains many tiny font assets requiring separate requests. Fewer smaller requests reduce network overhead. The actual requirement is cloudFront cache misses are high because query parameters vary without affecting image content. Recommended corrective action: Normalize cache-key settings to only meaningful parameters. Smaller cache-key variation improves reusable hit ratio.

For the alternative failure dynamic per-user API calls cannot be shared safely among different users, the control Restrict caching to safe routes and authentication-aware cache keys is relevant: personalized responses require private cache behavior. Here the evidence instead is cloudFront cache misses are high because query parameters vary without affecting image content. The selected technical mechanism is Normalize cache-key settings to only meaningful parameters: smaller cache-key variation improves reusable hit ratio.

Configure CloudFront edge caching for versioned images solves a different operational problem where users fetch identical large images from S3 multiple times per session. Cache hits reduce object GET and transfer from origin. It does not directly address cloudFront cache misses are high because query parameters vary without affecting image content. The case calls for Normalize cache-key settings to only meaningful parameters, since smaller cache-key variation improves reusable hit ratio.

Use a CDN with suitable caching and origin selection would help if users around the world retrieve the same download from one Region. Edge distribution reduces repeated long-haul delivery. That is not the symptom described here: a public large-file downloader serves data through EC2 even though no application logic is needed. The matching response is Serve signed S3/CloudFront URLs directly to authorized clients, because direct object delivery avoids compute proxy traffic.

For the alternative failure a tenant downloads hundreds of terabytes but the organization cannot attribute cost, the control Apply cost allocation, logging and relevant Requester Pays only where supported and contractual is relevant: metering/attribution informs sustainable data distribution pricing. Here the evidence instead is a public large-file downloader serves data through EC2 even though no application logic is needed. The selected technical mechanism is Serve signed S3/CloudFront URLs directly to authorized clients: direct object delivery avoids compute proxy traffic.

Cache eligible exports or stage them once rather than regenerating for every request solves a different operational problem where a high-volume product exports multi-gigabyte files repeatedly to the same consumer. Reuse reduces compute and network transmission. It does not directly address a public large-file downloader serves data through EC2 even though no application logic is needed. The case calls for Serve signed S3/CloudFront URLs directly to authorized clients, since direct object delivery avoids compute proxy traffic.

The option Cache eligible exports or stage them once rather than regenerating for every request addresses a separate condition: a high-volume product exports multi-gigabyte files repeatedly to the same consumer. Reuse reduces compute and network transmission. The actual requirement is private app calls to AWS APIs still pay NAT charges for regional S3. Recommended corrective action: Add S3 gateway endpoints and validate route selection. Gateway endpoint traffic avoids NAT data processing.

Evaluate interface endpoint hourly/data charges against NAT usage would help if a service requires private access to an AWS API with no gateway endpoint type. PrivateLink cost tradeoffs vary with volume and AZ count. That is not the symptom described here: a production service relies on one unpatched NAT instance that requires manual failover. The matching response is Prefer managed NAT gateways with appropriate AZ placement when operational cost matters, because managed NAT removes instance patching and custom failover workload.

For the alternative failure private subnets use a NAT gateway solely to access S3, the control Deploy S3 gateway endpoints instead of NAT for S3 calls is relevant: gateway endpoints eliminate S3-specific NAT data fees. Here the evidence instead is a production service relies on one unpatched NAT instance that requires manual failover. The selected technical mechanism is Prefer managed NAT gateways with appropriate AZ placement when operational cost matters: managed NAT removes instance patching and custom failover workload.

The competing option Add appropriate AZ-local gateways and route tables if reliability and transfer cost warrant would be useful when two private AZs send all internet traffic through a NAT gateway located in only one AZ. Local gateways reduce cross-zone egress paths.
