Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)
Administrative distance refers to the trustworthiness of a particular route. Routes with the smallest metric to a destination indicate the best path.
What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)
IP addresses Layer 1 statuses
What are two functions of a router? (Choose two.)
It determines the best path to send packets. It connects multiple IP networks.
Refer to the exhibit. What is the purpose of the highlighted field in the line that is displayed from the show ip route command?
It indicates that this route was learned via EIGRP
Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.)
R1 does not know a route to any remote networks. The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12.
A network administrator is implementing dynamic routing protocols for a company. Which command can the administrator issue on a router to display the supported routing protocols?
Router(config)# router ?
What is one feature that distinguishes routers from Layer 2 switches?
Routers support a variety of interface types. Switches typically support Ethernet interfaces.
Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227?
Send the packet out the Serial0/0/0 interface.
A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0. However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?
The interface fa0/0 has not been activated.
When a computer is pinging another computer for the first time, what type of message does it place on the network to determine the MAC address of the other device?
an ARP request
Which two items are used by a host device when performing an ANDing operation to determine if a destination address is on the same local network? (Choose two.)
destination IP address subnet mask
Refer to the exhibit. A network administrator issues the show ip route command on R2. What two types of routes are installed in the routing table? (Choose two.)
directly connected networks routes that are learned through the EIGRP routing protocol
Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. Which two types of routes are displayed in the routing table? (Choose two.)
local host route directly connected network
Fill in the blank. When a router receives a packet, it examines the destination address of the packet and looks in the_______________table to determine the best path to use to forward the packet.
routing table
What address changes as a packet travels across multiple Layer 3 Ethernet hops to its final destination?
source Layer 2 address
Refer to the exhibit. PC1 attempts to connect to File_server1 and sends an ARP request to obtain a destination MAC address. Which MAC address will PC1 receive in the ARP reply?
the MAC address of the G0/0 interface on R1
A network administrator configures a router by the command ip route 0.0.0.0 0.0.0.0 209.165.200.226. What is the purpose of this command?
to provide a route to forward packets for which there is no route in the routing table
