The service must ___ incoming requests efficiently even under heavy load.
To handle requests means to receive and process incoming API calls. Handle is the standard backend term, behind "request handler." Do, work, and manage out are vague or non-idiomatic. Engineers "handle thousands of requests per second," so handle requests is the correct collocation.

During peak hours, the cluster needs to ___ traffic without dropping connections.
To serve traffic means to respond to incoming requests/load. Serve is the precise term, behind "server" and "serving capacity." Give, feed, and deliver out are not idiomatic. Operators "serve traffic across replicas," so serve traffic is the correct collocation.

For long-running work, the API will ___ a job onto a background queue instead of blocking the request.
To queue a job means to enqueue work for asynchronous background processing. Queue is the precise term, behind "job queue" and "message queue." Line up, stack, and pile are informal. Engineers "queue the job for the worker to process," so queue a job is the correct collocation.
4 / 5
When a downstream call fails, the client should ___ with exponential backoff rather than hammering the service.
To retry with backoff means to re-attempt a failed operation after increasing delays. Retry is the standard resilience term, behind "retry policy" and "exponential backoff." Redo, repeat, and try over are informal. Engineers "retry with exponential backoff and jitter," so retry with backoff is the correct collocation.
5 / 5
If a dependency is unavailable, a resilient service should ___ gracefully rather than failing completely.
To degrade gracefully means to reduce functionality in a controlled way when a dependency fails, instead of crashing. Degrade is the precise reliability term, behind "graceful degradation." Fall, drop, and sink are not idiomatic here. Engineers "degrade gracefully when the cache is down," so degrade gracefully is the correct collocation.
