Exam AZ-304 topic 5 question 13 discussion

CORRECT If we send many events & throughput is a concern: use AMQP https://vincentlauzon.com/2018/06/05/event-hubs-ingestion-performance-and-throughput/

The choice to use AMQP or HTTPS is specific to the usage scenario. AMQP requires the establishment of a persistent bidirectional socket in addition to transport level security (TLS) or SSL/TLS. AMQP has higher network costs when initializing the session, however HTTPS requires additional TLS overhead for every request. AMQP has significantly higher performance for frequent publishers and can achieve much lower latencies when used with asynchronous publishing code. https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-features#publishing-an-event

Correct...another question from my AZ-304 exam.

https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-amqp-protocol-guide Answer is A

Answer is correct (A)...AMQP protocol, nuff said.

Correct: B Event Hubs' limit on data retention based on time is to prevent large volumes of historic customer data getting trapped in a deep store that is only indexed by a timestamp and only allows for sequential access. AMQP has higher network cost ... no pint to add it.

This is correct, but only because it states that it will communicate with HTTP. if a https connection is required the overhead would be higher with amqp.

Definitely NOT B and D
