Which of the following best describes the difference between VPWS and VPLS?

Options:

Unlike VPLS. VPWS appears as a multi-hop network to the customers.

Unlike VPWS, VPLS allows customers to view the network as a routed network.

Unlike VPWS, VPLS is a service where customer MAC addresses are learned.
