By using unique message IDs
By reducing the message expiration time
Correct!
Wrong!
16.What does "at-least-once" delivery guarantee in a Pub/Sub system mean?
Every message will be delivered exactly once
Every message will be delivered at least once, but duplicates may occur
Every message will be delivered only if the subscriber is active
Every message will be delivered within a certain time frame
Correct!
Wrong!
17.What is a common use case for Pub/Sub in the context of IoT (Internet of Things)?
To provide file storage for IoT devices
To manage user accounts on IoT devices
To stream data from IoT devices to processing systems
To provide a user interface for IoT devices
Correct!
Wrong!
18.What is a good practice when designing Pub/Sub message data?
Including sensitive information for ease of processing
Making messages as large as possible
Including only necessary information in the message
Using a proprietary format for message data
Correct!
Wrong!
19.In which scenario would you consider using a pull delivery method in Pub/Sub?
When the subscriber can't maintain a persistent connection
When you want to push messages as soon as they're published
When you want to reduce the processing load on the subscriber
When the subscriber's processing rate is unpredictable
Correct!
Wrong!
20.What is the main advantage of the push delivery method in a Pub/Sub system?
It allows the subscriber to control the rate of message delivery
It ensures that messages are delivered in the order they were published
It delivers messages to the subscriber as soon as they're published
It allows the publisher to control the rate of message delivery
Correct!
Wrong!
21.What is IAM in the context of Pub/Sub security?
A messaging protocol
A type of encryption
A method of authentication and authorization
A type of firewall
Correct!
Wrong!
22.Which of the following is a security best practice for Pub/Sub?
Giving all users full permissions
Using the default service account for all operations
Restricting access using IAM policies
Storing sensitive data in message payloads
Correct!
Wrong!
23.How can you monitor the number of undelivered messages in a Pub/Sub subscription?
By counting the number of messages in the topic
By using a metric provided by Google Cloud Monitoring
By asking subscribers to report undelivered messages
It's not possible to monitor undelivered messages
Correct!
Wrong!
24.In a high-volume Pub/Sub system, how can you ensure that a message isn't lost if a subscriber crashes during processing?
