問題文
An Enterprise customer plans to use the smallest, sleep-capable dyno tier for internal tools to save cost, and to mix that tier with larger dynos inside the same app. Which statements should the architect give as feedback? (Select two.)
選択肢
- The smallest tiers can be scaled horizontally to absorb bursts, and a second dyno of the same size can be added for the length of a peak.
- Sleeping dynos still receive external HTTP traffic while asleep, and the first request after a quiet period is served without any delay.
- Dyno types cannot be mixed across runtime tiers within one application; only types scoped to the same runtime can be combined.
- The smallest sleep-capable tier is not available to Heroku Enterprise customers.
- Mixing tiers is allowed as long as every process type declares the same number of dynos, because the platform only requires the formation to be symmetrical across the process types that an application declares and scales.
