Step 1: Understand auto scaling and load balancing roles
Auto scaling adjusts server count based on demand; load balancing spreads traffic evenly.
Step 2: Identify correct combined behavior
Auto scaling adds or removes servers based on demand; load balancing distributes traffic to these servers correctly describes how these two work together to improve availability.
Final Answer:
Auto scaling adds or removes servers based on demand; load balancing distributes traffic to these servers -> Option B
Quick Check:
Auto scaling + load balancing = Better availability [OK]
