Q1Domain Verified
In the context of "The Complete Heroku Dyno Performance Tuning Course 2026," what is the primary trade-off when scaling dyno RAM usage upwards from a standard tier to a performance tier, assuming CPU remains constant?
Increased dyno startup time but reduced application latency.
Enhanced ability to handle concurrent requests but a potential increase in memory leaks.
Decreased dyno startup time but higher per-dyno operational cost.
Improved I/O operations but a negligible impact on CPU-bound tasks.
Q2Domain Verified
According to the principles taught in "The Complete Heroku Dyno Performance Tuning Course 2026," what is the most effective strategy to mitigate "dyno sleeping" issues for a web application that experiences irregular but critical traffic spikes?
Implement a background worker process that periodically sends "wake-up" requests to the web dyno.
Continuously increase the number of free-tier dynos to ensure at least one is always awake.
Upgrade to a paid dyno tier (e.g., Eco or Basic) which guarantees the dyno remains active.
Configure an external monitoring service to ping the application's health endpoint every minute.
Q3Domain Verified
In the context of optimizing dyno memory usage as detailed in "The Complete Heroku Dyno Performance Tuning Course 2026," what is the most significant implication of a constant stream of Out-Of-Memory (OOM) errors in your application logs?
Your application is likely experiencing a memory leak, and the dyno may need to be restarted frequently.
The dyno's allocated RAM is insufficient for the current workload, necessitating a tier upgrade.
Heroku's garbage collection mechanism is not performing optimally, requiring application code adjustments.
The database connection pool is too large, consuming excessive memory on the dyno.
