ANSWERS GRADED A
The Open Systems Interconnection reference model (OSI/RM) Network Layer serves which
primary purpose? - It uses Layer 3 addresses to create multiple routed networks.
The address 68.56.189.17 belongs to which Internet protocol (IP) class? - Class A
What happens to a datagram sent by a higher level protocol to a 127.x.y.z address? - The
datagram loops back inside the host and never leaves the network interface card (NIC).
Which device evaluates and acts upon a packet's Internet protocol (IP) address? - Router.
The Network Layer must do what to a received frame first, in order to determine the route
over which it will forward the datagram to the next network? - Decapsulate the packet.
What network information can be determined from a logical Internet protocol (IP) address? - The
host portion and network portion.
The physical address of a device is processed by which layer of the Open Systems
Interconnection reference model (OSI/RM)? - The Physical Layer.
Which layer of the Open Systems Interconnection reference model (OSI/RM) would you suspect
as being the problem when packets are arriving at the server but no information is being returned
to the client? - The Data Link Layer.
All computers running on the transmission control protocol/Internet protocol (TCP/IP) suite have
which of the following in common? - Each computer is assigned its own Internet protocol (IP)
address.
A repeater operates at which layer of the Open Systems Interconnection reference model
(OSI/RM)? - The Transport Layer.
,Which Dynamic Host Configuration Protocol (DHCP) network address allocation mechanism
assigns a host a temporary IP address? - Dynamic
Which two choices are examples of trivial file transfer protocol (TFTP) use? (Choose two.) -
Download router upgrades. And
Software upgrades to IP telephones.
How does the Domain Name System (DNS) resolve fully qualified domain names (FQDN) to IP
addresses? - By looking up the names in an address mapping database.
Which TCP/IP application allows us to transfer files either within a browser or at the command
line? - File transfer protocol (FTP).
Which statement best describes Internet Message Access Protocol (IMAP)? - IMAP allows users
to scan email headers and choose email messages to download from the email server.
To resolve fully qualified domain names (FQDN) to binary IP addresses, resolvers contact which
type of TCP/IP application server? - Domain Name System (DNS).
Which protocol allows clients to locate and download IP addressing and configuration
information on an automatically renewable (lease) basis? - Dynamic Host Configuration Protocol
(DHCP).
Which TCP/IP application allows a network user to remotely log on and manipulate a network
device? - Telnet.
Which three of the following are Dynamic Host Configuration Protocol (DHCP) address
allocation mechanisms? (Choose three.) - Automatic, Dynamic, Manual
Internet email uses which two protocols? (Choose two.) - Simple Mail Transfer Protocol
(SMTP). And Post Office Protocol version 3 (POP3).
If a Dynamic Host Configuration Protocol (DHCP) client fails to renew its lease at the 50-
percent point, what happens next? - It attempts to obtain a lease at 87.5-percent lease time.
,Of the five trivial file transfer protocol (TFTP) packet types, which three choices below are
TFTP packet types? (Choose three.) - Read request, Write request, Acknowledgement
If you want to locate a previously saved Uniform Resource Locator (URL) so that you can
quickly return to it as needed, where on the browser toolbar would you look? - Favorites
, What happens when the browser application finishes downloading the files necessary to display a
web page? - The browser and server drop the connections, and the browser maintains the page
and its elements in memory.
Which best describes why an hypertext transfer protocol (HTTP) server can handle multiple
simultaneous connections? - HTTP is stateless, which means the server has no knowledge of
previous connections after they are dropped.
For what purpose would you choose to run the Telnet application? - To configure a router
Which three of the following are common Telnet application uses? (Choose three.) - Connect to
an online database, Connect remotely to run a specific application, Connect to a router for
network information
Which file transfer protocol (FTP) command allows you to change directories within a file
listing? - CD
For what application is file transfer protocol (FTP) an excellent choice? - To download large
files.
A file transfer protocol (FTP) server administrator can control server access in which three
ways? (Choose three.) - Make only portions of the drive visible, Control read and write
privileges, Limit file access
Which is the best reason to use the file transfer protocol (FTP) application? - When you need to
pass large files over a slow connection
The file transfer protocol (FTP) server process can run as which two of the following? (Choose
two.) - Daemon, Windows service
As a result of issuing the file transfer protocol (FTP) DIR command, each file listing entry
begins with a "-"; what does the "-" indicate? - The entries are files
Which two choices are TCP/IP email protocols? (Choose two.) - Simple Mail Transfer Protocol
(SMTP). , Internet Message Access Protocol (IMAP).
