Question 22

+3 marksOne or more correct options

In a web application using webhooks and Redis for real-time data synchronization:
Scenario: An order management system where:

• Redis stores the current order cache
• Multiple concurrent requests update the cache
Which statements about this architecture are true?

Select all that apply.

  1. A

    Webhooks guarantee that the notification service will process events in the exact order they were triggered

  3. C

    The webhook will automatically retry if the notification service is temporarily unavailable

  4. D

    Webhooks use HTTP POST requests to communicate events asynchronously
