What topics does the CDN practice test PDF cover?

The PDF covers CDN architecture (origin servers, edge nodes, PoPs), cache-control headers and invalidation strategies, CDN use cases (static assets, video streaming, DDoS mitigation), SSL/TLS edge termination, HTTP/2 and HTTP/3 performance, WAF integration, origin pull vs. push, and key CDN metrics like cache hit ratio and TTFB.

Which certifications test CDN knowledge?

CDN concepts appear in AWS Certified Solutions Architect (CloudFront), Microsoft Azure Administrator (Azure CDN), Google Cloud Professional Cloud Architect, and vendor-specific Cloudflare certifications. Understanding CDN architecture is also tested in CompTIA Cloud+ and general cloud practitioner exams.

What is the difference between cache hit ratio and TTFB?

Cache hit ratio measures the percentage of requests served directly from the CDN edge cache without going back to the origin server — a higher ratio means lower origin load and faster response. TTFB (Time to First Byte) measures the time from the client sending a request to receiving the first byte of the response, and CDNs improve it by serving from nearby edge nodes rather than distant origin servers.

What is origin pull vs. origin push in CDN?

In origin pull (the most common model), the CDN fetches content from the origin server on the first request and caches it at the edge for subsequent requests. In origin push, you proactively upload content to CDN edge nodes before any request is made. Origin push is best for content you know will be in high demand immediately, such as a software release or a scheduled live event.

Free CDN Practice Test PDF Download

Content Delivery Networks are a core topic in cloud certification exams including AWS Solutions Architect, Azure Administrator, and Google Cloud Professional. This free CDN practice test PDF gives you printable multiple-choice questions covering CDN architecture, caching strategies, edge computing, and performance optimization — so you can study wherever you are, even without internet access.

The PDF covers everything from how origin servers hand off content to edge nodes, to cache-control headers, TTL expiration, and real-world CDN use cases like video streaming, static asset delivery, and DDoS mitigation. Download it once and review it on any device or print it out for desk study.

Pro Tip: Focus your CDN study time on areas where you score lowest. Most exam questions test application of knowledge, not memorization.

What the CDN Practice Test PDF Covers

CDN Architecture and Edge Infrastructure

Questions test your knowledge of origin servers, edge nodes, and Points of Presence (PoPs). You need to understand cache hierarchies — how content flows from origin to regional edge caches to end users — and how CDNs reduce latency by serving assets from the closest geographic location.

Caching Policies and Invalidation

The exam tests cache-control header values (max-age, s-maxage, no-cache, no-store), TTL-based expiration, manual purge APIs, and versioned URL strategies. You need to know when to use each invalidation approach and the trade-offs involved in aggressive vs. conservative caching.

CDN Use Cases and Performance

Scenarios cover static asset delivery, video streaming (adaptive bitrate), API acceleration, and DDoS mitigation. HTTP/2 multiplexing and HTTP/3 QUIC improvements are tested, along with origin pull vs. origin push models and when each applies.

Security and Configuration

Questions cover SSL/TLS termination at the edge, Web Application Firewall (WAF) integration, custom domain configuration with CNAME records, CDN failover and origin health checks, and how cache hit ratio affects both performance and cost.

✓Understand CDN architecture: origin servers, edge nodes, and PoPs

✓Review SSL/TLS termination at the edge and security implications
✓Compare HTTP/2 multiplexing vs. HTTP/3 QUIC performance improvements
✓Understand origin pull vs. origin push and when to use each
✓Study WAF integration with CDN and edge security policies
✓Know how to configure custom domains and CNAME records with CDN providers
✓Review CDN metrics: cache hit ratio, TTFB, throughput, and origin offload percentage
