Implementing Cisco Service Provider VPN Services (SPVI) — Question 7
The CTO of a company requires the support of a network consultant to deliver an MPLS solution without resigning to a certain degree of redundancy and scalability. Which solution effectively scales to hundreds or thousands of sites?
Answer options
- A. L2VPN with the broadcast traffic processed at the ingress PE.
- B. L3VPN with direct LSP connectivity between all PEs.
- C. L2VPN by encapsulating multiple frame formats with interworking.
- D. L3VPN using a hierarchical topology of N-PEs and U-PEs.
Correct answer: D
Explanation
The correct answer, D, describes a scalable L3VPN architecture that allows for effective management of large networks through a hierarchical design. Options A and C focus on L2VPN solutions that do not provide the same level of scalability and redundancy needed for hundreds or thousands of sites. Option B, while offering direct connections, lacks the hierarchical approach that enhances scalability.
