Which two of these are examples of an off-net address class in a route plan? (Choose two.)

International is an off-net address class because calls to international destinations must traverse a PSTN gateway to reach public telephone infrastructure outside the organization's private network.

Emergency (911/E911) is an off-net address class because emergency calls must be delivered to the public safety answering point (PSAP) via the PSTN, requiring an off-net route through a gateway.

Intrasite is an on-net address class because it describes calls between IP phones within the same physical site, which remain entirely on the corporate IP network without touching the PSTN.

Intersite is an on-net address class because it represents calls between company locations that travel across the corporate WAN, not the public telephone network.

Voicemail is an on-net address class because voicemail calls route internally to a messaging system such as Cisco Unity Connection, which resides within the corporate network.
