An architect wants to calibrate CloudFront cache behavior so that dynamic API responses are never cached while static assets are cached for 24 hours. How should cache policies be configured?
Answer: Use separate cache behaviors with CachingDisabled policy for the API path and a custom TTL policy for static paths
CloudFront supports multiple cache behaviors per distribution; assigning CachingDisabled to the /api/* path and a custom TTL policy to /static/* provides precise per-path cache control.
A company runs a fleet of IoT-connected industrial sensors that send telemetry to AWS IoT Core. The team needs to calibrate alert thresholds centrally and push updated configuration to all devices. Which feature enables this?
Answer: AWS IoT Jobs
AWS IoT Jobs allows you to define and send remote operations — such as configuration updates or firmware pushes — to a set of devices, tracking execution status per device.
An operations team must ensure that AWS Lambda function concurrency is capped at 200 to prevent downstream database overload during traffic spikes. How should this be configured?
Answer: Configure a reserved concurrency limit of 200 on the specific Lambda function
Setting a reserved concurrency limit on a specific Lambda function ensures it never scales beyond that threshold, protecting downstream resources from overload.
A data engineering team needs to recalibrate Kinesis Data Streams throughput by adjusting the shard count in response to sustained backlog growth. What is the correct approach?
Answer: Use the UpdateShardCount API to rescale the stream
The UpdateShardCount API allows online resharding of a Kinesis Data Stream, increasing or decreasing shard count without data loss or stream recreation.
During a maintenance window, an architect needs to temporarily suspend an Auto Scaling group from launching or terminating instances while manual work is performed. Which action achieves this?
Answer: Suspend the Launch and Terminate scaling processes
Suspending the Launch and Terminate processes in an Auto Scaling group halts all scale-out and scale-in activities while preserving the existing running instances.
A team must verify that their multi-region active-active architecture fails over correctly before a production maintenance event. Which AWS service provides pre-built runbooks for testing and executing failover procedures?
Answer: Amazon Route 53 Application Recovery Controller
Amazon Route 53 Application Recovery Controller provides readiness checks, routing controls, and safety rules specifically designed to safely execute and validate multi-region failover.
An architect must ensure that Elastic Beanstalk environments receive platform updates (OS patches, runtime upgrades) during a defined maintenance window with minimal downtime. Which update type should be selected?
Answer: Managed platform updates with instance replacement
Elastic Beanstalk Managed Platform Updates apply patch-level and minor updates automatically during a configured maintenance window, replacing instances in a rolling fashion to minimize downtime.
