S 172.16.1.0 [1/0] via 172.16.2.2
When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?
native VLAN ID
What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch?
The port becomes inactive.
Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router?
To be used as a backup route
When configuring a router as part of a router-on-a-stick inter-VLAN routing topology, where should the IP address be assigned?
To the subinterface
Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?
native
Refer to the graphic. Which command would be used on router A to configure a static route to direct traffic from LAN A that is destined for LAN C?
A(config)# ip route 192.168.4.0 255.255.255.0 192.168.3.2
Refer to the exhibit. Which is the best way for PC A and PC B to successfully communicate with sites on the Internet?
Configure a default route from R1 to ISP and a static route from ISP to R1.
Refer to the exhibit. What routing solution will allow both PC A and PC B to access the Internet with the minimum amount of router CPU and network bandwidth utilization?
Configure a static default route from R1 to Edge, a default route from Edge to the Internet, and a static route from Edge to R1.
What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
Default route
Which type of static route that is configured on a router uses only the exit interface?
Directly connected static route
What is a disadvantage of using router-on-a-stick inter-VLAN routing?
Does not scale well beyond 50 VLANs
What must the network administrator do to remove Fast Ethernet port fa0/1 from VLAN 2 and assign it to VLAN 3?
Enter the switchport access vlan 3 command in interface configuration mode.
A Cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on Fa0/5?
It allows only VLAN 30 on Fa0/5.
Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 How would an administrator test this configuration?
Manually shut down the router interface used as a primary route.
Port Fa0/11 on a switch is assigned to VLAN 30. If the command no switchport access vlan 30 is entered on the Fa0/11 interface, what will happen?
Port Fa0/11 will be returned to VLAN 1.
Refer to the exhibit. The small company shown uses static routing. Users on the R2 LAN have reported a problem with connectivity. What is the issue?
R1 needs a static route to the R2 LAN.
