Amazon AWS Certified Solutions Architect - Associate SAA-C03 Bundle

The option Deploy S3 gateway endpoints instead of NAT for S3 calls addresses a separate condition: private subnets use a NAT gateway solely to access S3. Gateway endpoints eliminate S3-specific NAT data fees. The actual requirement is two private AZs send all internet traffic through a NAT gateway located in only one AZ. Recommended corrective action: Add appropriate AZ-local gateways and route tables if reliability and transfer cost warrant. Local gateways reduce cross-zone egress paths.

Evaluate NAT instance or gateway-free endpoint architecture after assessing risk would help if a tiny development VPC has high NAT gateway fixed-hour costs. Low-volume cost tradeoffs include operations and availability. That is not the symptom described here: two private AZs send all internet traffic through a NAT gateway located in only one AZ. The matching response is Add appropriate AZ-local gateways and route tables if reliability and transfer cost warrant, because local gateways reduce cross-zone egress paths.

Evaluate interface endpoint hourly/data charges against NAT usage solves a different operational problem where a service requires private access to an AWS API with no gateway endpoint type. PrivateLink cost tradeoffs vary with volume and AZ count. It does not directly address two private AZs send all internet traffic through a NAT gateway located in only one AZ. The case calls for Add appropriate AZ-local gateways and route tables if reliability and transfer cost warrant, since local gateways reduce cross-zone egress paths.

For the alternative failure a customer site uses internet VPN for sustained high-transfer workloads with unpredictable throughput, the control Assess Direct Connect economics and required reliability based on actual utilization is relevant: hybrid connectivity choice should reflect steady throughput and operations. Here the evidence instead is an east-coast analytics team downloads the same west-coast dataset every hour. The selected technical mechanism is Run the analytics near the dataset or replicate only necessary outputs: processing locality reduces inter-region movement.

Add CloudFront with resized/optimized assets solves a different operational problem where a public web tier sends full-resolution uncompressed media on every page load. Edge caching and smaller objects reduce transferred bytes. It does not directly address an east-coast analytics team downloads the same west-coast dataset every hour. The case calls for Run the analytics near the dataset or replicate only necessary outputs, since processing locality reduces inter-region movement.

The competing option Aggregate locally and export summary batches would be useful when an application sends events to a second AWS Region only to produce local reporting summaries. Regional aggregation reduces cross-region bytes. The present issue is an east-coast analytics team downloads the same west-coast dataset every hour; it is more directly addressed by Run the analytics near the dataset or replicate only necessary outputs. Processing locality reduces inter-region movement.

For the alternative failure a customer site uses internet VPN for sustained high-transfer workloads with unpredictable throughput, the control Assess Direct Connect economics and required reliability based on actual utilization is relevant: hybrid connectivity choice should reflect steady throughput and operations. Here the evidence instead is an on-prem backup transfers the full dataset nightly despite few changes. The selected technical mechanism is Use DataSync incremental copy to transfer only differences: incremental transfer reduces bandwidth.

Align replication destinations to approved DR policy would help if a data tier sends backups to three Regions when only one DR copy is required. Unnecessary geographic copies increase network/storage cost. That is not the symptom described here: network line items increase but ownership attribution is absent. The matching response is Enable detailed Cost and Usage Report dimensions and cost allocation tags, because cost allocation data helps identify accountable network spend.

For the alternative failure network interfaces send more bytes after a feature added uncompressed JSON events, the control Compress or batch eligible event payloads before transmission is relevant: batching and compression reduce transferred bytes. Here the evidence instead is network line items increase but ownership attribution is absent. The selected technical mechanism is Enable detailed Cost and Usage Report dimensions and cost allocation tags: cost allocation data helps identify accountable network spend.

The competing option Prefer appropriate private ALB, VPC endpoints or routing where supported would be useful when an internal microservice uses internet-facing endpoints for calls inside AWS. Private connectivity avoids unnecessary public-facing hops. The present issue is network line items increase but ownership attribution is absent; it is more directly addressed by Enable detailed Cost and Usage Report dimensions and cost allocation tags. Cost allocation data helps identify accountable network spend.

Compare savings with reliability impact before collocating critical components solves a different operational problem where a cost team treats every cross-AZ transfer as removable without considering availability requirements.
