Question

Which of the following is a technique for creating Internet maps? Each correct answer represents a complete solution. Choose two.

Options

AActive Probing
BAS PATH Inference
CObject Relational Mapping
DNetwork Quota

Explanation

Internet mapping uses Active Probing to discover network topology via probe packets and AS PATH Inference to map autonomous system relationships using BGP routing data.

Common mistakes.

C. Object Relational Mapping (ORM) is a software development technique for mapping relational database tables to programming language objects and has no relation to network topology discovery.
D. Network Quota refers to bandwidth or data usage limits enforced on users or interfaces and is not a methodology for discovering or mapping Internet topology.
