In a ROAS configuration, why is it important to configure the switch port connected to the router as a trunk port?

• To increase the bandwidth of the port

• To enable port security features

• To assign a static IP address to the port

In a ROAS configuration you notice that devices in different VLANs cannot communicate. What could be a potential reason for this issue?

• The router's subinterfaces are not configured with the correct IP addresses.

• The switch ports are configured as access ports instead of trunk ports.

• The router is using the wrong encapsulation type.

• All of the above

What is a strategic consideration you must keep in mind when configuring ROAS regarding the router's physical interface?

• The interface must support high-speed data transfer.

• The interface must be capable of handling multiple subinterfaces.

• The interface must be configured with a static IP address.

• The interface must be connected to a Layer 3 switch.

In a ROAS setup, what is the impact of not configuring the correct encapsulation type on a router subinterface?

• The router will not be able to route traffic between VLANs.

• The router will drop all incoming traffic.

• The router will only route traffic to the default VLAN.

• The router will automatically correct the encapsulation type.
