Question $2$

A network administrator investigates a user problem. The user can reach hosts on the same network, but is unable to communicate to remote networks.The network administrator tries to ping the gateway address configured on the host device and is unsuccessful. What is the most likely cause of the problem?

radio$\_$button$\_$unchecked

The address of the remote device is incorrect.

radio$\_$button$\_$unchecked

The IP address of the user is incorrectly configured.

radio$\_$button$\_$unchecked

TCP$/$IP is not installed on the host device.

radio$\_$button$\_$unchecked

The default gateway address is incorrect.

Question $3$

Which type of address can be shared through NAT to enable home network devices to send and receive data over the internet?

radio$\_$button$\_$unchecked

private IPv$6$ address

radio$\_$button$\_$unchecked

broadcast MAC address

radio$\_$button$\_$unchecked

registered public IP address

radio$\_$button$\_$unchecked

registered MAC address

Question $4$

When a LAN is connected to the internet using a wireless router, how do devices on the LAN communicate on the internet using NAT?

radio$\_$button$\_$unchecked

Each device must wait to receive a token from the wireless router in order to communicate to the internet via NAT.

radio$\_$button$\_$unchecked

All devices must share the single public IPv$4$ address assigned to the wireless router in order to communicate to the internet via NAT.

radio$\_$button$\_$unchecked

Each LAN must select a single client device from the wireless router settings that can communicate to the internet via NAT.

radio$\_$button$\_$unchecked

Only a small group of high priority client devices can be chosen by the wireless router to communicate to the internet using NAT.

Question $5$

A home network is using NAT on the router connecting it to the internet. The PCs on the home network receive private IP addresses through DHCP$.$ When a PC sends a packet to a web server on the internet, what is the source IP address in the packet header when it arrives at the web server?

radio$\_$button$\_$unchecked

a registered public IP address statically configured on the PC

radio$\_$button$\_$unchecked

the broadcast IP address of the external network connecting to the ISP

radio$\_$button$\_$unchecked

a registered public IP address assigned to the external router interface

radio$\_$button$\_$unchecked

the private IP address assigned to the PC through DHCP

Question $6$

What will happen if the default gateway address is incorrectly configured on a host?

radio$\_$button$\_$unchecked

The host will have to use ARP to determine the correct address of the default gateway.

radio$\_$button$\_$unchecked

The host cannot communicate with hosts in other networks.

radio$\_$button$\_$unchecked

A ping from the host to $127\mathrm{.}0\mathrm{.}0\mathrm{.}1$ would not be successful.

radio$\_$button$\_$unchecked

The host cannot communicate with other hosts in the local network.

radio$\_$button$\_$unchecked

The switch will not forward packets initiated by the host.

Question $7$

Which destination address is used in an ARP request frame?

radio$\_$button$\_$unchecked

$0\mathrm{.}0\mathrm{.}0\mathrm{.}0$

radio$\_$button$\_$unchecked

AAAA.AAAA.AAAA

radio$\_$button$\_$unchecked

FFFF$.$FFFF$.$FFFF

radio$\_$button$\_$unchecked

$255\mathrm{.}255\mathrm{.}255\mathrm{.}255$

radio$\_$button$\_$unchecked

the physical address of the destination host

Question $8$

The ARP table in a switch maps which two types of address together?

radio$\_$button$\_$unchecked

Layer $2$ address to a Layer $4$ address

radio$\_$button$\_$unchecked

Layer $3$ address to a Layer $4$ address

radio$\_$button$\_$unchecked

Layer $4$ address to a Layer $2$ address

radio$\_$button$\_$unchecked

Layer $3$ address to a Layer $2$ address

Question $9$

A host needs to reach another host on a remote network, but the ARP cache has no mapping entries. To what destination address will the host send an ARP request?

radio$\_$button$\_$unchecked

the unicast MAC address of the remote host

radio$\_$button$\_$unchecked

the broadcast MAC address

radio$\_$button$\_$unchecked

the subnet broadcast IP address

radio$\_$button$\_$unchecked

the unicast IP address of the remote host

Question $10$

Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?

radio$\_$button$\_$unchecked

DHCP

radio$\_$button$\_$unchecked

UDP

radio$\_$button$\_$unchecked

ARP

radio$\_$button$\_$unchecked

TCP

Question $11$

PT Activity

Launch the PT activity. What is the MAC address of the default gateway for PC$0?$

radio$\_$button$\_$unchecked

$00$D$0.$FF$0$D$.$A$02$B

radio$\_$button$\_$unchecked

$0060\mathrm{.}5$C$55\mathrm{.}7401$

radio$\_$button$\_$unchecked

$0002\mathrm{.}4$A$83.$A$602$

radio$\_$button$\_$unchecked

$0060\mathrm{.}70$DE$\mathrm{.}3192$

Question $12$

Refer to the exhibit. The switches have a default configuration. Host A needs to communicate with host D$,$ but host A does not have the MAC address for the default gateway. Which network devices will receive the ARP request sent by host A$?$

radio$\_$button$\_$unchecked

only hosts A$,$ B$,$ C$,$ and D

radio$\_$button$\_$unchecked

only hosts B and C

radio$\_$button$\_$unchecked

only hosts B$,$ C$,$ and router R$1$
