AKeep traffic at 5% for 5 days, then jump to 50%

BSwitch from 5% to 50% traffic immediately on day 2

CSend 50% traffic on day 1 and reduce to 5% on day 5

DIncrease traffic by 9% daily and monitor errors before next increase

Step-by-Step Solution

Solution:

Step 1: Understand gradual traffic increase
Gradual increase means small increments with monitoring to catch issues early.
Step 2: Evaluate options for safe rollout
Increase traffic by 9% daily and monitor errors before next increase increases traffic daily by about 9% (from 5% to 50% in 5 days) with monitoring, which is best practice.
Final Answer:
Increase traffic by 9% daily and monitor errors before next increase -> Option D
Quick Check:
Gradual increase + monitoring = safe rollout [OK]

Quick Trick: Increase traffic slowly and watch for errors daily [OK]
