200-301 Question #1164: Real Exam Question with Answer & Explanation

Question

What are two behaviors of a point-to-point WAN topology? (Choose two.)

Options

• AIt leverages a dedicated connection.
• BIt provides direct connections betwaen each router in the topology.
• CIt delivers redundancy between the central office and branch offices.
• DIt uses a single router to route traffic between sites.
• EIt connects remote networks through a single line.

Explanation

A point-to-point WAN topology establishes a dedicated communication link between two specific endpoints, connecting remote networks via this single, direct line.

Common mistakes.

• B. "Direct connections between each router in the topology" describes a full-mesh topology, not a point-to-point topology, which connects only two endpoints directly.
• C. While point-to-point connections can be part of a redundant design, a single point-to-point link itself does not inherently 'deliver redundancy'; it's a single path.
• D. A point-to-point link connects two sites or routers, but it does not dictate that a single router is used to route traffic between sites; each site will have its own router (or routers) at the endpoint.
