How can combining health checks with restart policies improve production container reliability?

AHealth checks expose ports; restart policies manage network traffic

BHealth checks reduce image size; restart policies speed up container start

CHealth checks disable logging; restart policies limit CPU usage

DHealth checks detect failures; restart policies recover containers automatically

Step-by-Step Solution

Solution:

Step 1: Understand role of health checks
They monitor container health and detect when the app is not working properly.
Step 2: Understand role of restart policies
They restart containers automatically when failures are detected to maintain uptime.
Step 3: Combine both for reliability
Health checks trigger failure detection; restart policies act on that to recover containers.
Final Answer:
Health checks detect failures; restart policies recover containers automatically -> Option D
Quick Check:
Health checks + restart policies = auto detect and recover [OK]

Quick Trick: Use health checks to detect, restart policies to recover [OK]
