In India, the business operates through Cloudflare India Private Limited, a private subsidiary of the US parent incorporated on December 2, 2021.

Cloudflare Interview Questions & Answers

Q: Walk me through the TLS handshake process step-by-step.

A: The client and server agree on a cipher, exchange keys and verify identity: the client sends a hello with supported ciphers, the server replies with its certificate, they derive a shared session key, then switch to encrypted traffic.

Answer by AI
  • The client sends a ClientHello listing TLS versions, cipher suites and a random value; the server replies with its choice and its certificate chain.
  • Both sides derive a shared symmetric key. In TLS 1.3 this uses an ephemeral Diffie-Hellman exchange, and the client validates the certificate against a trusted CA.
  • They confirm with Finished messages, then all further application data is encrypted with the negotiated session key. TLS 1.3 cuts this to a single round trip.

Q: Implement a function to check if an IP address belongs to a specific CIDR block.

A: Convert both the IP and the CIDR base to integers, build a mask from the prefix length, then compare the masked values: the IP is in the block when (ip & mask) equals (base & mask).

Answer by AI
  • Parse the address and the CIDR base into 32-bit integers (or 128-bit for IPv6).
  • Build the mask as (0xFFFFFFFF left-shifted by 32 minus prefix), which sets the top prefix bits.
  • The IP is inside the block when (ip AND mask) equals (base AND mask). Guard against prefix 0 to avoid an undefined shift.

Q: Write a thread-safe cache with an expiration policy (TTL).

A: Store each value with an expiry timestamp behind a concurrent map or a lock, treat entries past their expiry as absent on read, and evict them lazily on access plus a background sweep.

Answer by AI
  • Wrap each value in an entry that records its expiry time, and guard the map with a read/write lock or use a concurrent map.
  • On get, return the value only if now is before its expiry; otherwise remove it and report a miss (lazy expiration).
  • Add a periodic background sweep to purge stale entries so memory doesn't grow, and bound size with an LRU eviction if needed.

Q: Design a system to mitigate DDoS attacks.

A: Absorb and filter traffic at the edge: spread load across an anycast network, drop known-bad traffic early, rate-limit per client, and use behavioral scoring so real users pass while attack traffic is challenged or blocked.

Answer by AI
  • Use an anycast network so attack traffic is spread across many points of presence instead of hitting one origin.
  • Filter in layers: drop malformed packets and known-bad sources at L3/L4, then apply rate limits and a WAF for L7 floods.
  • Score requests by behavior and reputation, challenge suspicious clients, and keep the origin hidden behind the edge so it never takes direct load.
