Kafka - Kubernetes and Cloud Deployment

Given this pseudo-code for auto-scaling Kafka brokers:

if (cpu_usage > 80%) {
  add_broker()
} else if (cpu_usage < 30%) {
  remove_broker()
} else {
  do_nothing()
}

What happens if CPU usage is 85%?

AA broker is added

BNo change in brokers

CA broker is removed

DError occurs due to syntax

Step-by-Step Solution

Solution:

Step 1: Check CPU usage condition
CPU usage is 85%, which is greater than 80%.
Step 2: Determine action based on condition
Since cpu_usage > 80%, the code calls add_broker() to add a broker.
Final Answer:
A broker is added -> Option A
Quick Check:
CPU > 80% triggers add_broker() [OK]

Quick Trick: CPU > 80% means add broker, CPU < 30% means remove [OK]
