An Event Hubs application has four useful partitions and forty consumers in one group, but throughput does not improve. What should the architect investigate?

Choose the single best answer.

A.Partition concurrency and uneven key distribution before adding more consumers
B.Whether Event Hubs automatically creates a new partition for every worker
C.Whether all groups share exactly one global checkpoint by definition
D.The number of APIM developer portal users

✓ Correct answer

Partition concurrency and uneven key distribution before adding more consumers

Partition ownership and hot keys constrain useful parallelism; extra consumers cannot automatically create partition capacity. Portal users are unrelated, independent groups do not share one global checkpoint by definition, and workers do not each cause an automatic partition. Source guide: PDF page(s) 51.
