Geo-Distribution Vocabulary

5 questions · Multi-Region Deployment Language

1. A network architect says: "We use anycast for our DNS and DDoS mitigation layer." What is anycast?

A protocol that multicasts packets to all servers simultaneously for redundancy A routing technique where the same IP address is announced from multiple locations — traffic is routed to the topologically nearest node A load balancing algorithm that distributes traffic based on geographic region assignments

2. A legal team informs engineering: "We must keep all EU user data in EU regions — we cannot store or process it elsewhere." What term describes this legal and regulatory requirement?

Data locality Data residency Data partitioning

3. A CDN engineer mentions "PoPs" repeatedly. What does PoP stand for and what is its function?

Point of Performance — a server optimised for low-latency computation at the network edge Point of Presence — a physical location where CDN servers cache content and serve it to nearby users Protocol of Proximity — the routing rule that sends users to the nearest data centre

4. An architect proposes: "We use geolocation routing so that users from Germany always go to our Frankfurt region." What is the key limitation of this approach compared to latency-based routing?

Geolocation routing cannot handle failover — the system will not redirect traffic if the Frankfurt region goes down Geolocation routing routes by geographic location, not actual network performance — a user in Germany might actually have better latency to Amsterdam if Frankfurt is congested Geolocation routing only works with IPv4 addresses and cannot support modern IPv6 networks

5. An engineer says: "We have data sovereignty requirements that affect where we can run compute." What does data sovereignty mean in cloud architecture context?

The ability for users to download and delete their own data at any time The principle that data is subject to the laws and governance of the country in which it is stored or processed A database permission model where each tenant owns and controls their own data partition
