Why each option

To configure a control policy that routes traffic between Barcelona and Paris through London in a full-mesh SD-WAN network, the engineer must create a centralized control policy. This is done by navigating to the Centralized Policy section and selecting 'Custom Options' to define a new policy.

AConfiguration > Policies tab. Centralized Policy selected on the left. On the right, 'Custom Options' dropdown is open with 'Centralized Policy' selected, showing a list of policy types: CLI Policy, Lists, Topology, Forwarding Class/QoS, Access Control Lists, Route Policy.Correct

Centralized policies are used to influence routing and traffic flow across the entire SD-WAN fabric, making them appropriate for orchestrating inter-site communication like forcing traffic through a specific hub (London). The 'Custom Options' dropdown allows for the creation of new policy types, including topology policies, which are used to define how sites communicate.

BConfiguration > Policies tab. Centralized Policy selected on the left. The 'Localised Policy' button is not visible. On the right, the 'Custom Options' dropdown is not open, but 'Centralized Policy' is shown as the active view, listing policy types.

This option shows 'Centralized Policy' as the active view but implies the 'Custom Options' dropdown is not open, which is needed to create a new custom policy.

CConfiguration > Policies tab. Centralized Policy selected on the left. On the right, 'Custom Options' dropdown is open, showing 'Custom Options' as the selected view, listing policy types.

While 'Custom Options' is open, it shows 'Custom Options' as the selected view, not specifically 'Centralized Policy' for creating a new policy, which is the direct path for defining central policies.

DConfiguration > Policies tab. Centralized Policy selected on the left. On the right, 'Custom Options' dropdown is open with 'Localised Policy' selected as the active view, listing policy types.

Localized policies apply only to the specific WAN Edge router where they are configured, making them unsuitable for controlling inter-site traffic flow across the entire SD-WAN.
