> 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.*

A configured default route.

A configured static route to the network 209.165.200.224.

Routes that are learned through the OSPF routing protocol.
Routes that are learned through the EIGRP routing protocol.

> 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 is a directly connected route.

It indicates that this is a default route.

It indicates that this route was learned via EIGRP.*

It indicates that the route has been deleted from the routing table.

> Refer to the exhibit. Match the description with the routing table entries. (Not all options are used.)

Route source protocol = D(which is EIGRP).

Destination network = 10.3.0.0.

Metric=21024000.

Administrative distance = 1.

Next hop = 172.16.2.2.

Route timestamp 00:22:15.

> Refer to the exhibit. A network administrator has configured R1 as shown. When the administrator checks the status of the serial interface, the interface is shown as being administratively down. What additional command must be entered on the serial interface of R1 to bring the interface up?.

IPv6 enabled.

No shutdown.*

End.

Clockrate 128000.

> In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host?. (Choose three.)

IP address.*

DNS server address.

Default gateway.*

DHCP server address.

Subnet mask.*

Hostname.

> 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 GigabitEthernet0/0 interface.

Drop the packet.

Send the packet out the GigabitEthernet0/1 interface.

Send the packet out the Serial0/0/0 interface.*

> What two pieces of information are displayed in the output of the show ip interface brief command?. (Choose two.)

IP addresses.*

MAC addresses.

Next-hop address.

Interface descriptions.

Speed and duplex settings.

Layer 1 statuses.*

> Which command is used to configure an IPv6 address on a router interface so that the router will combine a manually specified network prefix with an automatically generated interface identified?.

Ipv6 address ipv6-address/prefix-length.

Ipv6 address ipv6-address/prefix-length eui-64.*

Ipv6 enable.

Ipv6 address ipv6-address/prefix-length link-local.

> 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 configuration needs to be saved first.

No packets with a destination network of 172.16.1.0 have been sent to R1.

The interface fa0/0 has not been activated.*

The subnet mask is incorrect for the IPv4 address.

> Which two statements correctly describe the concepts of administrative distance and metric?.

The metric is always determined based on hop count.

A router first installs with higher administrative distances.

Administrative distance refers to the trustworthiness of a particular route.*

The value of the administrative distance can not be altered by the network administrator.*

The metric varies depending which Layer 3 protocol is being routed, such as IP.
Routes with the smallest metric to a destination indicate the best path.

> 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 on File_server1.

The MAC address of the G0/0 interface on R2.

The MAC address of the G0/0 interface on R1.*

> Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusion can be drawn from the routing table?. (Choose two.)

The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A:12.*

Packets that are destined for the network 2001:DB8:ACAD:2::54/128 will be forwarded through Fa0/0.

The network FF:00::/8 is installed through a static route command.

R1 does not show a route to any remote networks.

> What is one feature that distinguishes routers from Layer 2 switches?.

Switches use tables of information to determine how to process data traffic. Routers do not.

Routers support a variety of interface types. Switches typically support Ethernet interfaces.*

Switches move packets from one physical interface to another. Routers do not.

Routers can be configured with IP addresses. Switches cannot.

> What are the two functions of a router?. (Choose two.)

It controls the flow of data via the use of Layer 2 addresses.

It determines the best path to send packets.*

It increases the size of the broadcast domain.

It manages the VLAN database.

It connects multiple IP networks.*

> 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.*

Route that is learned through the EIGRP routing protocol.

Static route.

> 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 forward packets destined for the network 0.0.0.0 to the device with IP address 209.165.200.226.

To forward all packets to the device with IP address 209.165.200.226.

To provide a route to forward packets for which there is no route in the routing table.*

To add a dynamic route for the destination network 0.0.0.0 to the routing table.

> Which statement describes a route that has been learned dynamically?.

It has an administrative distance of 1.

It is identified by the prefix C in the routing table.

It is unaffected by changes in the topology of the network.

It is automatically updated and maintained by routing protocols.*

> Fill in the blank.

When a router receives a packet, it examines the destination address of the packet and looks in the #"routing"# table to determine the best path to use to forward the packet.

> 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.)

Source MAC address.

Subnet mask.*

Destination MAC address.

Network number.

Destination IP address.*

> A packet moves from a host on one network to a device on a remote network within the same company. If NAT is not performed on the packet, which two items remain unchanged during the transfer of the packet from source to destination?. (Choose two.)

Source MAC address.

Destination MAC address.

Source IP address.*

Destination IP address.*

Source ARP table.

Layer 2 header.

> What type of IPv6 address is required as a minimum on IPv6 enabled interfaces?.

Destination port.

Destination IP.

Source IP.
