The interface ID exit interface The IP address of the next-hop neighbor

trunk

Refer to the exhibit. The network administrator needs to configure a default route on the Border router. Which command would the administrator use to configure a default route that will require the least amount of router processing when forwarding packets?

Border(config)# ip route 0.0.0.0 0.0.0.0 s0/0/1

The network administrator configures the router with the ip route 172.16.1.0 255.255.255.0 172.16.2.2 command. How will this route appear in the routing table?

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.

Refer to the exhibit. Which default static route command would allow R1 to potentially reach all unknown networks on the Internet?

R1(config)# ipv6 route ::/0 G0/1 fe80::2

Refer to the exhibit. R1 receives a packet destined for the IP address 192.168.2.10. Out which interface will R1 forward the packet?

Serial0/0/1

switchport trunk native vlan 66

172.16.0.0/24

Which two statements describe classful IP addresses?

The number of bits used to identify the hosts is fixed by the class of the network. All subnets in a network are the same size.
