A small accounting office is setting up a wireless network to connect end devices and to provide internet access. In which two scenarios does a wireless router perform Network Address Translation (NAT)? (Choose two.). when a host is sending packets to the ISP in order to request a speed increase for Internet services. when a host is sending packets to a local server in order to update the network media settings and music playlists. when a host is sending packets to a remote site owned by the manufacturer of the wireless router in order to request a digital copy of the device manual. when a host is sending a print job to a network printer on the LAN. when a host is sending HTTP packets to the wireless router in order to update the network addressing of the LAN.

Refer to the exhibit. A switch with a default configuration connects four hosts. The ARP table for host A is shown. What happens when host A wants to send an IP packet to host D?. Host A sends out the packet to the switch. The switch sends the packet only to the host D, which in turn responds. Host D sends an ARP request to host A. Host A sends an ARP request to the MAC address of host D. Host A sends out a broadcast of FF:FF:FF:FF:FF:FF. Every other host connected to the switch receives the broadcast and host D responds with its MAC address.

A network administrator has a multi-floor LAN to monitor and maintain. Through careful monitoring, the administrator has noticed a large amount of broadcast traffic slowing the network. Which device would you use to best solve this problem?. switch. router. host. server.

An employee is having connectivity issues. Why might a network technician try to ping the default gateway from the employee laptop?. to verify connectivity with the device that provides access to remote networks. to verify that an IP address was provided by the DHCP server. to determine if the laptop address is included in the DNS server. to verify that the SVI interface on the switch is configured correctly.

Refer to the exhibit. PC1 issues an ARP request because it needs to send a packet to PC3. In this scenario, what will happen next?. SW1 will send an ARP reply with its Fa0/1 MAC address. RT1 will send an ARP reply with its own Fa0/0 MAC address. RT1 will send an ARP reply with the PC3 MAC address. RT1 will forward the ARP request to PC3. RT1 will send an ARP reply with its own Fa0/1 MAC address.

Refer to the exhibit. Host H2 sends a unicast message to host H6. Which destination IP address is contained in the header of the packet when it reaches host H6?. the IP address assigned to the network adapter on host H2. the IP address assigned to the network adapter on host H6. the IP address of the FastEthernet0/1 interface on router R1. the IP address of the FastEthernet0/0 interface on router R1.

Which command would a technician use to display network connections on a host computer?. ipconfig. nslookup. tracert. netstat.

How are port numbers used in the TCP/IP encapsulation process?. Source port and destination port numbers are randomly generated. Source port numbers and destination port numbers are not necessary when UDP is the transport layer protocol being used for the communication. If multiple conversations occur that are using the same service, the source port number is used to track the separate conversations. Destination port numbers are assigned automatically and cannot be changed.

Two pings were issued from a host on a local network. The first ping was issued to the IP address of the default gateway of the host and it failed. The second ping was issued to the IP address of a host outside the local network and it was successful. What is a possible cause for the failed ping?. The default gateway is not operational. The TCP/IP stack on the default gateway is not working properly. Security rules are applied to the default gateway device, preventing it from processing ping requests. The default gateway device is configured with the wrong IP address.

A network technician attempts to ping www.example.net from a customer computer, but the ping fails. Access to mapped network drives and a shared printer are working correctly. What are two potential causes for this problem? (Choose two.). The Windows domain or workgroup name that is configured on the computer is incorrect. The computer has been assigned a static IP address. The target web server is down. DNS service is unavailable on the customer network. The HTTP protocol is not working properly on the target server.

For what purpose are IPv4 addresses utilized?. An IPv4 address is burned into the network card to uniquely identify a device. An IPv4 address is used to identify the number of IP networks available.​. An IPv4 address is used to uniquely identify a device on an IP network. An IPv4 address is used to uniquely identify the application that requested the information from a remote device.

A user is setting up a home wireless network. A global address is to be used in NAT translations for traffic flowing through the wireless router. How is this global address assigned?. The wireless router will act as a DHCP client in order to receive global addressing from the ISP. The default gateway IP address of the LAN device is used as the global address for NAT translations through the wireless router. The network administrator will choose an available IP address from the LAN and configure the global addressing of the wireless router. The host devices will select an unused IP address on the LAN for performing NAT through the wireless router.
