Cisco Chapter 10 test for final

Which protocol can be used to transfer messages from an email server to an email client? SMTP POP3 SNMP HTTP

POP3

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.​

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

session layer

used to arrange the communication between source and destination applications and responsible for the state of the conversation

Which TCP/IP model layer is closest to the end user? application internet network access transport

Application

domain name

the name that is used to uniquely identify a website and is used instead of the IP address

SMTP

the protocol responsible for sending email

A user is attempting to access http://www.cisco.com/ without success. Which two configuration values must be set on the host to allow this access? DNS server source port number HTTP server default gateway source MAC address

DNS server, and default gateway

What is a common protocol that is used with peer-to-peer applications such as WireShare, Bearshare, and Shareaza? Ethernet Gnutella POP SMTP

Gnutella

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

HTTP

Hypertext Transfer Protocol - used to request and transfer hypertext data between clients and servers

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.

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

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.

In FTP transactions, an FTP client uses the pull method to download files from an FTP server. True False

True

URL

Uniform Resource Locator - the "friendly" address that is used in a web browser bar and that corresponds to the IP address of the site

IMAP

a protocol that is used in email retrieval It leaves copy of messages on the server.

POP

a protocol that is used to retrieve email from a server It deletes messages from the server by default.

DHCP

a service that is used in networks to automatically configure IP addresses on devices

nslookup

a tool used to query the DNS system to find the IP addresses for domain names, and vice versa

client-server network

an architecture that allows network clients to request services directly from network servers

peer-to-peer network

consists of peer machines that exchange data with each other without a dedicated server

Which command is used to manually query a DNS server to resolve a specific host name? nslookup ipconfig /displaydns tracert ping

nslookup

A wired laser printer is attached to a home computer. That printer has been shared so that other computers on the home network can also use the printer. What networking model is in use? peer-to-peer (P2P) client-based master-slave point-to-point

peer-to-peer (P2P)

application layer

provides data exchange and the interface between the system and the network

presentation layer

the layer in the OSI model that is responsible for formatting, compressing, and encrypting data
