Q1Domain Verified
In the context of a global CDN, what is the primary advantage of employing edge locations that are geographically closer to end-users when serving dynamic content, as opposed to relying solely on origin servers?
Enhanced security through distributed DDoS mitigation capabilities at every edge node.
Greater control over origin server load balancing by offloading all request processing to the CDN.
Improved cache hit ratios for static assets by consolidating requests at the edge.
Reduced latency due to fewer network hops and faster DNS resolution at the edge.
Q2Domain Verified
A large e-commerce platform experiences a sudden surge in traffic during a flash sale, leading to origin server overload and high error rates. Which CDN feature, when properly configured, is most crucial for mitigating this specific issue and maintaining service availability?
Content optimization techniques like image compression and minification.
Advanced caching strategies, including stale-while-revalidate and cache bursting.
Load balancing across multiple origin servers and intelligent health checks.
Geo-blocking and access control lists (ACLs) to restrict traffic from specific regions.
Q3Domain Verified
When designing a global CDN strategy for an application that serves both high-definition video streams and real-time interactive gaming data, what is the most critical consideration for ensuring optimal performance for both use cases?
Implementing separate delivery networks or specialized routing for streaming and gaming traffi
C) Prioritizing low latency above all else, even if it means slightly reduced cache efficiency.
Utilizing a single, high-capacity edge network capable of handling all traffic types uniformly.
Maximizing cache TTL (Time To Live) for all content to reduce origin fetches.
