Recall & Review

beginner

What is the purpose of the RabbitMQ Shovel plugin in a multi-DC setup?

The Shovel plugin moves messages from one RabbitMQ broker to another, even across different data centers, ensuring reliable message transfer.

How does RabbitMQ Federation differ from Shovel in multi-DC environments?

Federation links exchanges or queues across brokers to share messages dynamically, while Shovel actively copies messages from source to destination.

What is a key advantage of using Federation over Shovel for multi-DC message sharing?

Federation allows decentralized message sharing with less configuration and automatic reconnection, making it more flexible for dynamic topologies.

beginner

What configuration element is essential to define in a Shovel setup?

You must define the source and destination URIs, queues or exchanges to shovel from and to, and connection parameters.

Why is multi-DC message replication important in RabbitMQ?

It ensures high availability, disaster recovery, and low latency by replicating messages across geographically separated data centers.

Which RabbitMQ feature actively copies messages from one broker to another?

A Shovel

B Federation

C Clustering

D Mirroring

Shovel actively copies messages from a source broker to a destination broker.

What does Federation in RabbitMQ primarily connect?

A Brokers to databases

B Exchanges or queues across brokers

C Clients to brokers

D Only queues within the same broker

Federation links exchanges or queues across different brokers to share messages.

In a multi-DC setup, why might you choose Federation over Shovel?

A Because it requires manual message copying

B It only works within a single data center

C For automatic reconnection and decentralized sharing

D It disables message replication

Federation supports automatic reconnection and decentralized message sharing.

Which configuration is NOT required for a Shovel setup?

A Client IP address

B Destination URI

C Source URI

D Queues or exchanges to shovel

Client IP address is not required; source and destination URIs and queues/exchanges are essential.

What is a main benefit of replicating messages across multiple data centers?

A Increased single point of failure

B Slower message delivery

C Reduced message durability

D Improved availability and disaster recovery

Replicating messages improves availability and disaster recovery.
