the combination of a source IP address and port number or a destination IP address and port number.

the combination of the source and destination IP address and source and destination Ethernet address.

7. How does a client computer determine what source port number to assign to a UDP header?

The port number is based on a well-known port number that is assigned to the application on the sending device.

The port number is based on the application that created the data.

The port number is random within the range of dynamic port numbers.

The port number is based on a well-known port number that is open on the destination device.

8. What layer of the TCP/IP suite makes sure that all the data packets of a message arrive safely at the destination?

application

network access

transport

internet

9. What is an advantage of UDP over TCP?

UDP communication is more reliable.

UDP acknowledges received data.

UDP communication requires less overhead.

UDP reorders segments that are received out of order.

10. What is the valid most compressed
format possible of the IPv6 address 2001:0DB8:0000:AB00:0000
:0000:0000:1234?

11. Which type of IPv6 address is not routable and used only for communication on a single subnet?

global unicast address

loopback address

link-local address

unspecified address

unique local address

12. What purpose does NAT64 serve in IPv6?

It converts the 48-bit MAC address into a 64-bit host address that can be used for automatic host addressing.

It converts regular IPv6 addresses into 64-bit addresses that can be used on the Internet.

It converts IPv6 packets into IPv4 packets.

It enables companies to use IPv6 unique local addresses in the network.

It translates private IPv6 addresses into public IPv6 addresses.

13. Which statement accurately describes dynamic NAT?

It provides a mapping of internal host names to IP addresses.

It dynamically provides IP addressing to internal hosts.

It provides an automated mapping of inside local to inside global IP addresses.

It always maps a private IP address to a public IP address.

14. What is the result if the default gateway address is misconfigured on a PC?

The PC can communicate with devices both in remote networks and in the same network.

The PC can communicate with devices in remote networks but not with those in the same network.

The PC can communicate with devices in the same network but not with those in remote networks.

The PC cannot communicate with any devices.

15. How is a DHCPDISCOVER transmitted on a network to reach a DHCP server?

A DHCPDISCOVER message is sent with the IP address of the default gateway as the destination address.

A DHCPDISCOVER message is sent with a multicast IP address that all DHCP servers listen to as the destination address.

A DHCPDISCOVER message is sent with the IP address of the DHCP server as the destination address.

The PC cannot communicate with any devices.

16. A host PC is attempting to lease an address through DHCP. What message is sent by the server to let the client know it is able to use the provided IP information?

DHCPDISCOVER

DHCPOFFER

DHCPACK

DHCPREQUEST

DHCPNACK

17. Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server?

DHCPDISCOVER

DHCPOFFER

DHCPACK

DHCPREQUEST

18. Refer to the exhibit. PC1 is configured to obtain a dynamic IP address from the DHCP server. PC1 has been shut down for two weeks. When PC1 boots and tries to request an available IP address, which destination IP address will PC1 place in the IP header?

192.168.1.255

192.168.1.8

192.168.1.1

255.255.255.255

19. Why is DHCP for IPv4 preferred for use on large networks?

Large networks send more requests for domain to IP address resolution than do smaller networks.

DHCP uses a reliable transport layer protocol.

It is a more efficient way to manage IPv4 addresses than static address assignment is.

Hosts on large networks require more IPv4 addressing configuration settings than do hosts on small networks.

It prevents sharing of files that are copyrighted.

20. Which three types of nodes should be assigned static IP addresses on a network? (Choose three.)

mobile laptops

tablets

desktop PCs

gateways

servers

printers

21. What type of server would use IMAP?

DNS

Telnet

DHCP

FTP

22. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What is the IP address of this server?

192.168.10.100

209.165.201.4

192.168.10.1

209.165.201.3

23. Which type of applications are best suited to use UDP as the transport layer protocol?

applications that require data to be reassembled in a specific order

applications that require minimal transmission delay

applications that require stateful sessions

applications that require flow control

24. Which three pieces of information are identified by a URL? (Choose three.)

the version of the browser

the IP address of the gateway

the MAC address of the web server

the protocol that is being used

the location of the resource

the domain name that is being accessed

25. How many bits make up the single IPv6 hextet :10CD:?

26. An employee is having connectivity issues. Why might a network technician try to ping the default gateway from the employee laptop?

to verify that an IP address was provided by the DHCP server

to verify connectivity with the device that provides access to remote networks

to verify that the SVI interface on the switch is configured correctly

to determine if the laptop address is included in the DNS server

27. A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 172.30.8.0/24. There are 7 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts?
