router will drop the packet.
- The router will forward the packet out interface FastEthernet 0/1.2 and
interface FastEthernet 0/1.3.

8. What
condition is required to enable Layer 3 switching?
- All
participating switches must have unique VLAN numbers.

routing enabled.*
- All routed subnets must be on the same VLAN.
9. Which
type of inter-VLAN communication design requires the configuration of multiple
subinterfaces?
- legacy
inter-VLAN routing
- routing for the management VLAN
- router on a stick*
- routing via a multilayer switch
10.
Refer
to the exhibit. A network administrator is configuring RT1 for inter-VLAN
routing. The switch is configured correctly and is functional. Host1, Host2,
and Host3 cannot communicate with each other. Based on the router
configuration, what is causing the problem?
- Routers do not support 802.1Q encapsulation on subinterfaces.
- IP
addresses on the subinterfaces are incorrectly matched to the VLANs.*
- Each subinterface of Fa0/0 needs separate no shutdown commands.
- Interface Fa0/0 is missing IP address configuration information.
11. How
is traffic routed between multiple VLANs on a multilayer switch?
- Traffic is routed via
internal VLAN interfaces.*
- Traffic is routed via physical interfaces.
- Traffic is broadcast out all physical interfaces.
- Traffic is routed via subinterfaces.
12.
Refer
to the exhibit. Communication between the VLANs is not occurring. What could be
the issue
- The wrong port on the router has been used.
- The
Gi1/1 switch port is not in trunking mode.*
- Default gateways have not been configured for each VLAN.
- A duplex issue exists between the switch and the router.
13. What
is a disadvantage of using router-on-a-stick inter-VLAN routing?
- does not support VLAN-tagged packets
- does
not scale well beyond 50 VLANs*
- requires the use of multiple router interfaces configured to operate as access
links
- requires the use of more physical interfaces than legacy inter-VLAN routing
14. Which
statement describes a disadvantage of using router subinterfaces for inter-VLAN
routing?
- Routed traffic must
contend for bandwidth on a single router interface.*
- All untagged traffic is dropped.
- It is more expensive than using individual router interfaces.
- Trunking cannot be used to connect the router to the switch.
