10. Refer to the exhibit. The router has been properly configured for the trunking interface. Which statement is true about the routing table on the router?

• Because the switch is not configured properly to trunk VLAN 1 and VLAN 2, the routing table of the router will not show routes to either VLAN .
• It will show one trunking route to 10.0.0.0/8.
• Because the switch port fa0/1 is in access mode, the routing table of the router will not show any routes.
• It should contain routes to the 10.10.10.0/24 and the 10.10.11.0/24 networks.
• It will show a next hop address of the switch for both VLANs.

11. Refer to the exhibit and the partial configuration taken on router RTA. Users on VLAN 5 cannot communicate with the users on VLAN 10. What should be done to fix the problem?

• Two static routes should be configured on the router, each pointing to each subnet.
• A dynamic routing protocol should be configured on the router.
• The Fa0/0 interface should be configured with a primary IP address of 10.10.5.1/24 and a secondary IP address of 10.10.10.1/24.
• The subinterfaces of the router should be configured with 802.1Q encapsulation.

12. Which two statements are true about routed ports on a multilayer switch? (Choose two.)

• A routed port is a physical switch port with Layer 2 capability.
• The interface vlan global configuration command is used to create a routed port.
• A routed port behaves like a regular router interface and supports VLAN subinterfaces.
• A routed port is not associated with a particular VLAN.

15. Which two statements are true about switched virtual interfaces (SVI) on a multilayer switch?

• An SVI is a physical switch port with Layer 3 capability.
• An SVI behaves like a regular router interface but does not support VLAN subinterfaces.
• To create an SVI requires removal of Layer 2 port functionality with the no switchport interface configuration command.
• Only one SVI can be associated with a VLAN.
• By default, an SVI is created for the default VLAN (VLAN1).

16. Refer to the exhibit. Which configuration should be applied on router R1 in order for host 1 to receive its IP configuration from the DHCP server?

• RTA interface Fa0/1 and RTB Fa0/1 should be configured with three subinterfaces, each with 802.1Q encapsulation.
• RTA interface Fa0/1 and RTB Fa0/1 should be configured with three subinterfaces, each with ISL encapsulation.
• A dynamic routing protocol or static routes should be configured on the routers.
