What is the role of replication in a Redis Cluster?
To optimize read operations by caching frequently accessed data on multiple nodes.
To provide fault tolerance and ensure data availability in case of node failures.
To enhance data security by encrypting data across multiple nodes.
To improve write performance by distributing write operations.
What is a key advantage of using Redis Streams for data ingestion compared to directly pushing data to a message queue like Kafka?
Redis Streams eliminate the need for message acknowledgments, simplifying the architecture.
Redis Streams allow for data persistence without relying on external systems.
Redis Streams inherently support complex data transformations within the stream.
Redis Streams offer more advanced message filtering capabilities.
How do subscribers express interest in receiving messages from specific channels?
By setting a special key in Redis with the channel name.
By establishing a direct connection to the publisher.
By writing a Lua script that listens for messages on the channel.
By executing the SUBSCRIBE command with the channel name.
SUBSCRIBE

What units can be used to specify the radius in the GEORADIUS command?
Only degrees
Only kilometers
Meters, kilometers, miles, feet
Only meters
What type of data structure is used internally by Redis Geospatial Indexes?

Which of the following is a crucial aspect of CI/CD pipelines for Redis?
Storing Redis data directly within the CI/CD pipeline.
Avoiding the use of version control for Redis configurations.
Manually configuring Redis instances in production.
Running performance and load tests on Redis deployments.
How are distances between geospatial points calculated in Redis?
Using Manhattan distance.
Distances are not calculated; only relative positions are stored.
Using the Haversine formula, accounting for Earth's curvature.
Using simple Euclidean distance.
