Networking & OS Fundamentals Deep Dive

Question

Akamai pushes on systems fundamentals: TCP/UDP, HTTP vs HTTPS, CPU/process behavior, and why a system fails in production.

What this round covers

• TCP vs UDP; the TLS handshake; HTTP/2 vs HTTP/1.1
• DNS resolution and caching
• Process/thread scheduling, context switches
• Diagnosing a CDN outage (cache rules vs origin failure)

Tips

Even coding questions pivot to 'how would this behave in a real environment'. Bring systems intuition.
