Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 423

In an MPLS network, which of the following describes the role of the Provider (P) router?

Answer options

• A. To connect to customer edge (CE) devices
• B. To connect to PE routers and act as transit routers
• C. To impose MPLS labels
• D. To filter VPN routes in the core

Correct answer: B

Explanation

The correct answer is B because Provider (P) routers are designed to connect to Provider Edge (PE) routers and act as transit points for traffic within the MPLS network. Options A and C are incorrect as those functions are typically associated with CE or PE routers, and option D is not a primary role of P routers, which do not filter VPN routes.
