What is a key consideration when designing a system using Redis Pub/Sub for high message volume?
Configuring Redis to prioritize Pub/Sub messages over other commands.
Ensuring that all messages are acknowledged by subscribers to prevent data loss.
Using persistent storage for all messages to facilitate auditing and replay.
Implementing a mechanism to handle slow subscribers to prevent message backlog.
What is the primary purpose of using a Redis Cluster?
To distribute data and handle larger datasets than a single Redis instance can manage.
To enable efficient message queuing and pub/sub functionality.
To enhance data security with built-in encryption.
To improve the performance of complex sorted set operations.

What is a 'hash slot' in the context of Redis Cluster?
A type of data structure that stores key-value pairs using a hash function.
A security feature that encrypts data before storing it in the cluster.
A virtual slot used to determine data distribution across the cluster.
A physical slot on the Redis server where data is stored.
When a transaction is executed with EXEC, and a watched key has been modified, what is the expected return value?
EXEC

Which of the following is a crucial aspect of CI/CD pipelines for Redis?
Storing Redis data directly within the CI/CD pipeline.
Running performance and load tests on Redis deployments.
Avoiding the use of version control for Redis configurations.
Manually configuring Redis instances in production.
What is the purpose of using a tool like 'Redis-benchmark' in a CI/CD pipeline?
To configure and manage Redis clusters across multiple regions.
To visualize the real-time performance metrics of a Redis instance.
To automatically back up and restore Redis data at scheduled intervals.
To simulate realistic workloads and assess Redis performance.
What is the role of a 'Dockerfile' in a Redis containerization workflow?
It defines the network configuration for the Redis container.
It provides a command-line interface for interacting with the container.
It automates the process of deploying the container to production.
It specifies the instructions to build a Docker image for Redis.
