hard📝 Application Q8 of 15

Kafka - Kubernetes and Cloud Deployment

Aif (cpu > 85) { add_broker() } else if (cpu < 25) { remove_broker() }

Bif (cpu < 25) { add_broker() } else if (cpu > 85) { remove_broker() }

Cif (cpu >= 85) { remove_broker() } else if (cpu <= 25) { add_broker() }

Dif (cpu > 25 && cpu < 85) { add_broker() } else { remove_broker() }

Step-by-Step Solution

Solution:

Step 1: Understand conditions
Add broker if CPU > 85%, remove if < 25%.
Step 2: Evaluate options
if (cpu > 85) { add_broker() } else if (cpu < 25) { remove_broker() } matches logic exactly.
Final Answer:
Option A -> Option A
