If you want to design an Application-layer protocol that provides fast, efficient
communication and doesn't work with large amounts of data, what Transport-layer
protocol would you design it to use? - ANS-UDP
Which of the following is the term for identifying packets used by TCP to establish a
connection? - ANS-Three-way handshake
What element of a DHCP server uses the client MAC address to ensure that the client is
leased the same address each time it requests an IP address? - ANS-Reservation
Which of the following is the first packet sent when a computer wants to lease an IP
address? - ANS-DHCPDiscover
Which of the following IPv6 features is an enhancement to IPv4? (Choose all that
apply.) - ANS-Larger address space
Built-in security
, When using TCP/IP, which of the following must computers on the same logical network
have in common? (Choose all that apply.) - ANS-Network ID
Subnet mask
How many bits must be reallocated from host ID to network ID to create 16 subnets? -
ANS-4
For the Class C network address 192.168.10.0, which of the following subnet masks
provides 32 subnets? - ANS-255.255.255.248
How many host bits are necessary to assign addresses to 62 hosts? - ANS-6
Which IP addressing process enables workstations to use private IP addresses to
access the Internet? - ANS-NAT
Which of the following represents a valid IPv6 address? - ANS-
2001:345:abcd::BEEF:44
Which of the following is a reason to subnet? (Choose all that apply.) - ANS-Networks
can be divided into logical groups.
Subnetting can decrease the size of broadcast domains.
Which of the following IP addresses has 12 bits in the host ID? - ANS-
12.156.109.252/20
You have a server with two NICs, each attached to a different IP network. You're having
problems communicating with devices on remote networks that send packets to one of
the interfaces. The server receives the packets fine, but the server's replies never reach
the intended destination network. Replies to packets that come in through the other
interface seem to reach their destination without any problems. What can you do that
will most likely solve the problem? - ANS-Use the route command to add routes to the
networks that aren't receiving replies.
You have just changed the IP address on a computer named computer5 in your domain
from 172.31.1.10/24 to 172.31.1.110/24. You were communicating with this computer
from your workstation fine right before you changed the address. Now when you try the
command ping computer5 from your workstation, you don't get a successful reply. Other
computers on the network aren't having a problem communicating with the computer.
Which command might help solve the problem? - ANS-arp -d
Which address can't be assigned to a host computer? - ANS-172.16.7.255/22
Which IPv6 transition technology can be used with NAT routers and has the address
prefix 2001::/32? - ANS-Teredo
How many bits are in the interface ID of an IPv6 address? - ANS-64
