What is the function of partitions in Azure Event Hubs?
To organize data associated with the parallelism required by event consumers
How do consumer groups and partitions relate to event processing in Azure Event Hubs?
Consumer groups enable multiple consuming applications to have a separate view of the event stream, while partitions organize data for parallelism
How are events delivered to Event Hubs consumers?
Through a session as they become available via the AMQP 1.0 protocol
What is the recommended number of active consumers for a given partition and consumer group pairing in Azure Event Hubs?
One active consumer
What is the role of throughput units in Azure Event Hubs?
Prepurchased units of capacity that control the throughput capacity of Event Hubs
How does Azure Event Hubs provide message streaming to consumers?
Through a partitioned consumer pattern in which each consumer only reads a specific subset, or partition, of the message stream
What is the recommended approach to scale an event processing application in Azure?
Run multiple instances of the application and have it balance the load among themselves
In the newer versions (5.0 onwards) of Azure Event Hubs, which component allows you to balance the load between multiple instances of your program?
EventProcessorClient (.NET and Java)
When designing the consumer in a distributed environment, what functionality does the Azure Event Hubs SDKs provide?
Event processor or consumer client
What is the recommended client for reading and processing events in most production scenarios in Azure Event Hubs?
EventProcessorClient
How is partition ownership distributed among active event processor instances in Azure Event Hubs?
Evenly distributed
What is the purpose of checkpointing in Azure Event Hubs?
Mark or commit the position of the last successfully processed event within a partition
How does Azure Event Hubs provide resiliency when an event processor goes down?
By using checkpointing to specify the location at which to start reading
What is the default behavior for processing events from different partitions in Azure Event Hubs?
Sequentially
What is the responsibility of the consumer when processing events in Azure Event Hubs?
Handle each event
What is the purpose of using two consumer groups and event processors in Azure Event Hubs?
To handle different types of processing tasks
What is the role of event processor instances in Azure Event Hubs?
Own and process events from one or more partitions
How does Azure Event Hubs handle thread safety when processing events from different partitions?
Sequentially for a given partition and concurrently for different partitions
What is the purpose of synchronization when accessing shared state across partitions in Azure Event Hubs?
To avoid data conflicts
What is the responsibility of the event processor when an event pump is running in Azure Event Hubs?
Queue up subsequent events and process them sequentially
What is the recommended approach for handling poisoned messages in Azure Event Hubs?
Do things relatively fast and as little processing as possible
What type of access control do publishers enable in Azure Event Hubs?
Fine-grained access control
How are Event Hubs clients authenticated for sending messages to publishers?
Assigned unique tokens uploaded to the client
What authentication methods does Azure Event Hubs support?
Microsoft Entra ID and shared access signatures (SAS)
What prevents clients from manufacturing tokens in Azure Event Hubs?
Clients aren't aware of the key
How can a request to Event Hubs service from a managed identity be authorized?
By configuring Azure role-based access control settings for the managed identity
What type of access rights are required for back-end applications to consume data from Event Hubs producers?
Manage rights or listen privileges
What is a key advantage of using Microsoft Entra ID with Event Hubs?
Credentials no longer need to be stored in the code
What is the role of an event publisher in Azure Event Hubs?
Define a virtual endpoint for an Event Hub and send messages
