Microservices - Testing Microservices

ASystem availability remains stable if redundancy exists

BSystem availability drops to zero immediately

CSystem crashes permanently after first kill

DSystem automatically scales down instances

Step-by-Step Solution

Solution:

Step 1: Analyze the chaos experiment impact
Killing one instance every 5 minutes tests resilience but does not remove all instances.
Step 2: Consider system redundancy
If the system has redundant instances, killing one does not reduce availability immediately.
Final Answer:
System availability remains stable if redundancy exists -> Option A
Quick Check:
Redundancy keeps availability stable during chaos [OK]

Quick Trick: Redundancy keeps system available despite instance failures [OK]

Common Mistakes:

Assuming system crashes immediately after one instance killed
Thinking availability drops to zero instantly
Believing system scales down automatically
