You want to optimize a CloudFront distribution to serve a global audience with dynamic content that changes frequently. Which combination of settings best achieves low latency and fresh content delivery?

AUse multiple edge locations with short TTL cache settings and origin failover

BUse a single origin with long TTL cache and disable edge caching

CUse edge locations only in one continent and long TTL cache

DDisable caching and serve all requests directly from origin

Step-by-Step Solution

Solution:

Step 1: Consider global audience needs
Multiple edge locations reduce latency by serving users nearby worldwide.
Step 2: Handle dynamic content freshness
Short TTL cache ensures content updates quickly; origin failover improves reliability.
Step 3: Evaluate other options
Long TTL delays updates; single continent edges increase latency; disabling cache increases load and latency.
Final Answer:
Use multiple edge locations with short TTL cache settings and origin failover -> Option A
Quick Check:
Global edges + short cache + failover = best freshness & speed [OK]

Quick Trick: Combine global edges with short cache for fresh, fast content [OK]

Common Mistakes:

MISTAKES

Using long TTL caches for dynamic content
Limiting edge locations to one region
Disabling caching causing high latency
