AUse a single origin and disable edge caching
BUse multiple origins with CloudFront and enable edge caching
CUse CloudFront without edge locations
DUse multiple origins but disable caching

  1. Step 1: Understand multi-origin and caching benefits

    Multiple origins allow flexibility; edge caching reduces latency by storing content near users.
  2. Step 2: Evaluate other options

    Disabling caching or edge locations reduces performance; single origin limits flexibility.
  3. Final Answer:

    Use multiple origins with CloudFront and enable edge caching -> Option B
  4. Quick Check:

    Multi-origin + edge caching = best performance [OK]
Quick Trick: Multiple origins plus caching boosts delivery [OK]
Common Mistakes:
  • Disabling caching reduces speed
  • Ignoring edge locations impact
  • Using single origin limits scalability
