B. API

C. Port

D. Virtual Connection

E. Session

Explanation: Sockets are created when a unique IP address and a port number are used to identify a connection between two hosts. These sockets provide an application program interface between processes and the TCP/IP suite.

& Domain 2.5: Define the purpose, function and/or use of the following protocols within TCP/IP: IP, TCP, UDP, FTP, TFTP, SMTP, HTTP, HTTPS, POP3/IMAP4, Telnet, ICMP, ARP, NTP.

& Domain 2.6: Define the function of TCP/UDP ports. Identify well-known imports.

A. Requires password

B. Part of TCP/IP suite

C. Allows file transport

D. Operates on Transport layer of OSI model

E. Uses a TCP/IP port

64. Users are complaining that the network performance is sluggish. There are only 10 users on this LAN and NetBIOS is the only protocol in use. What service can be added to this network to increase performance?

A. WINS to resolve NetBIOS names without resorting to broadcasts

B. DNS or HOST files to resolve names without resorting to broadcasts

C. 100mbp/s Network cards and switches

D. Add TCP/IP since this protocol is more efficient.

Explanation: Since NetBIOS name resolution is low in the process list, installing a WINS server to process the name resolution will greatly increase performance across the network.

& Domain 2.7: Identify the purpose of the following network services (e.g. DHCP/bootp, DNS, NAT/ICS, WINS and SNMP)

& Domain 4.8: Given a scenario, predict the impact of modifying, adding, or removing Network Services (e.g., DHCP, DNS, WINS, etc.) on network resources and users.


 

65. The unique number stamped onto every NIC card ever produced is known as a/an ________.

A. SPX Address

B. IP Address

C. MAC Address

D. IPX Address

E. IEEE Address

Explanation: MAC addresses are what make it possible to uniquely identify each and every NIC. They usually come in a series of six hexadecimal pairs, i.e., 00-08-C7-A3-44-7A. Part of this number identifies the maker.

& Domain 2.1: Given an example identify a MAC address.

& Domain 2.2: Identify the 7 layers of the OSI model and their functions.
