Docker - Resource Management

ADo not set any limits and rely on Docker to manage resources automatically

BAssign each container a CPU limit of 1 core and memory limit of 2GB

CSet CPU limit to 4 cores and memory to 8GB for each container

DGive each container unlimited CPU and memory to maximize performance

Step-by-Step Solution

Solution:

Step 1: Calculate fair resource distribution
With 4 cores and 8GB RAM, dividing resources evenly means 1 core and 2GB per container if running 4 containers.
Step 2: Understand why limits matter for stability
Setting limits prevents any container from using all resources, keeping the system responsive and stable.
Final Answer:
Assign each container a CPU limit of 1 core and memory limit of 2GB -> Option B
Quick Check:
Even resource limits = system stability [OK]

Quick Trick: Divide total resources fairly among containers [OK]
