Customer Network Design Requirements

You are asked to review the infrastructure requirements for provisioning a new network build that supports a customer seeking to use their service provider’s MPLS/VPN offering.

Which three considerations are relevant to this work?

Choose three
  • A supplicant roles in the current network layout
  • B server hypervisor and host OS selection
  • C backdoor connectivity requirements
  • D IGP protocols deployed in the customer environment
  • E site-to-site versus site-to-hub communications
Explanation

MPLS Layer 3 VPN design depends on the routing protocol used between customer-edge and provider-edge devices, any existing backdoor connectivity that can alter routing behavior or introduce loops, and the intended VPN topology, such as full site-to-site connectivity or hub-and-spoke communication. These factors determine route exchange, route filtering, and forwarding policy.
