hard📝 Best Practice Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Understand combined routing needs
You want to split traffic by weight, then route users to lowest latency server within each group.Step 2: Identify correct routing policy combination
Weighted routing controls traffic percentage, latency routing directs users to fastest server inside each weighted group.Step 3: Eliminate incorrect options
Simple routing cannot split traffic; latency routing alone can't assign weights; weighted routing alone ignores latency.Final Answer:
Use weighted routing with latency routing inside each weight group -> Option CQuick Check:
Combine weighted + latency for split and speed [OK]
Quick Trick: Combine weighted and latency routing for split and speed [OK]
Common Mistakes:
- Trying to use simple routing for traffic split
- Ignoring latency inside weighted groups
- Assuming latency routing can split traffic by weight
