Cloud Fundamentals

In a network design that uses the traditional tiered architecture, which two tiers connect to untrusted domains?

Choose two
  • A access
  • B WAN edge
  • C core
  • D aggregation
Explanation

The WAN edge forms the boundary to external WAN or service-provider networks, and the aggregation tier provides the interdomain aggregation and policy boundary before traffic enters the internal core. The core is intended for high-speed internal transport rather than direct connections to untrusted domains.
