Which of the following are application layer protocols (Choose 3) FTP TCP HTTP UDP SMTP
FTP, HTTP, SMTP
What is the responsibility of the presentation layer? Format, compress and encrypt data Access to the media using MAC addressing Establish maintain and terminate virtual circuits Choose the best path between destinations
Format, compress and encrypt data
What is a common protocol that is used with peer-to-peer applications such as WireShare, Bearshare, and Shareaza? Ethernet Gnutella POP SMTP
Gnutella
Hypertext Transfer Protocol - used to request and transfer hypertext data between clients and servers
HTTP
Match the protocol with its function: Used to transfer files for Web pages DHCP DNS FTP HTTP IMAP POP SMTP Telnet
HTTP
Which three protocols or standards are used at the application layer of the TCP/IP model? TCP HTTP MPEG GIF IP UDP
HTTP, MPEG, and GIF
Match the protocol with its function: Used for email retrieval. Messages KEPT on the server until manually deleted DHCP DNS FTP HTTP IMAP POP SMTP Telnet
IMAP
a protocol that is used in email retrieval It leaves copy of messages on the server.
IMAP
Why is DHCP 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 prevents sharing of files that are copyrighted. It is a more efficient way to manage IP addresses than static address assignment. Hosts on large networks require more IP addressing configuration settings than hosts on small networks.
It is a more efficient way to manage IP addresses than static address assignment.
Match the protocol with its function: Used for email retrieval. Messages are NOT stored on the server DHCP DNS FTP HTTP IMAP POP SMTP Telnet
POP
a protocol that is used to retrieve email from a server It deletes messages from the server by default.
POP
Which protocol can be used to transfer messages from an email server to an email client? SMTP POP3 SNMP HTTP
POP3
Match the OSI layers responsibility with the layer name Coding, conversion, compression of data to get it into the correct format Application Layer Presentation Layer Session Layer Transport Layer
Presentation Layer
What is the purpose of the nslookup command? Displays the default gateway of your host Resolves IP addressing issues with peer-to-peer clients Resolves host name to name servers Allows you to verify that DHCP is working correctly
Resolves host name to name servers
What is an advantage of SMB over FTP? Only with SMB can data transfers occur in both directions. Only SMB establishes two simultaneous connections with the client, making the data transfer faster. SMB is more reliable than FTP because SMB uses TCP and FTP uses UDP. SMB clients can establish a long-term connection to the server.
SMB clients can establish a long-term connection to the server.
Match the protocol with its function: Used for the transfer of mail messages and attachments DHCP DNS FTP HTTP IMAP POP SMTP Telnet
SMTP
the protocol responsible for sending email
SMTP
Match the OSI layers responsibility with the layer name Maintain dialog between source and destination applications Application Layer Presentation Layer Session Layer Transport Layer
Session Layer
Which layer handles the exchange of information, keeping dialog alive, and restarting dialogs that get disrupted? Session Layer Network Layer Presentation Layer Application Layer
Session Layer
Which three layers of the OSI model provide similar network services to those provided by the application layer of the TCP/IP model? physical layer session layer transport layer application layer presentation layer data link layer
Session layer, application layer, and presentation layer
Match the protocol with its function: Used to provide remote access DHCP DNS FTP HTTP IMAP POP SMTP Telnet
Telnet
What type of information is contained in a DNS MX record? the FQDN of the alias used to identify a service the IP address for an FQDN entry the domain name mapped to mail exchange servers the IP address of an authoritative name server
The domain name mapped to mail exchange servers
What is true about a client-server network? The network includes a dedicated server. Each device can function as a server and a client. Workstations access network resources using SAMBA or Gnutella. Each peer accesses an index server to get the location of a resource stored on another peer in what is considered a hybrid network system.
The network includes a dedicated server.
Match the OSI layers responsibility with the layer name Reliability, error correction, flow control Application Layer Presentation Layer Session Layer Transport Layer
Transport Layer
In FTP transactions, an FTP client uses the pull method to download files from an FTP server. True False
True
Uniform Resource Locator - the "friendly" address that is used in a web browser bar and that corresponds to the IP address of the site
URL
On a home network, which device is most likely to provide dynamic IP addressing to clients on the home network? a dedicated file server a home router an ISP DHCP server a DNS server
a home router
provides data exchange and the interface between the system and the network
application layer
an architecture that allows network clients to request services directly from network servers
client-server network
the name that is used to uniquely identify a website and is used instead of the IP address
domain name
Which command is used to manually query a DNS server to resolve a specific host name? nslookup ipconfig /displaydns tracert ping
nslookup
a tool used to query the DNS system to find the IP addresses for domain names, and vice versa
nslookup
