Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Process of directing a datagram from its source through an internetwork to its destination using the most efficient path.






2. Layer 4






3. Physical layer. 10 giga bit throughput. baseband transmission. twisted pair. max length is 100 meters. cat 6 or 7.






4. Firewall packet inspection that examines the data contained in a packet as well as the state of the connection between internal and external computers.






5. Only two wire pairs are reversed






6. Every node on the network is connected through a central device like a switch - cannot be disabled by a single malfunction in a workstation - scalable - - popular - expensive - cable malfunction will only effect 2 workstations - more fault tolerant.






7. Pipeline used to contain and protect cabling; usually made from metal






8. Is used to enable IP address to be assigned automatically by a DHCP server on a network.






9. A connector that is used for thin coax cable and that has a boyonet-like shell.






10. A permanent telephone connection between 2 locations that provide a predetermined amount of bandwidth at all times






11. Firewalls perform two basic security functions






12. Can use WPA to improve the security of data in transit






13. Device with little - if any - of it's own processing or disk capacity; depends on a host to supply it with applications and data-processing services






14. 3rd layer; protocols translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver






15. Is a method for automatically assigning address and other configuration parameters to network hosts.






16. Ensures reliablity of packet transmissions from node to node - Ensures that data is sent and received in the same order - Provides acknowledgement when a packet is received - Monitors for packet transmission errors and resends bad packets - Breaks la






17. An error detection method that calculates a value for the total size of the information fields contained in a frame. The value is inserted near the end of a frame by the Data Link layer on the sending node - and checked by the Data Link layer on the






18. LDAP






19. Ethernet communications at speeds up to 100 Mbps as defined under the IEEE 802.3u standard.






20. The more resistant to cross talk (STP)






21. Manages network communication - available on a CD-ROM for example - that is used to manage communications and how frames or packets are sent using a protocol.






22. A combination of LAN's - MAN's - or WAN's that provides computer users with an array of computer and network resources to complete different tasks.






23. A type of cable used in network wiring and is usually shielded - which means that it is more immune to interference then unshielded cables






24. The placement of data from a higher-layer protocol behind the header (and in some cases - between a header and trailer) of the next-lower-layer protocol. For example - an IP packet could be encapsulated in an Ethernet header and trailer before being






25. Field in a frame responsible for ensuring that data carried by the frame arrives intact. Uses an algorithm - such as CRC - to accomplish verification






26. Used to log on to a UNIX host






27. Layer 2






28. Internet protocol security-defines encryption - authentication - and key management for TCP/IP transmission






29. The physical layout of the cable and wireless network devices and the logical path followed by network frames and packets sent on the cable or by wireless transmissions






30. Prevents two nodes transmitting at the same time






31. Unwanted signals from sources near network cabling - such as motors and power lines






32. An IDPS that resides on particular computer or server (the host) and monitors activity only on that system. Also known as system integrity verifiers.






33. Occurs when attacker attempts to gain entry or disrupt normal operations of information systems - almost always with intent to do harm






34. Manages end-to-end delivery of data






35. Process of retransmitting a digital signal; repeats the pure signal without the noise






36. Small network 192-223






37. A data-link protocol used for remote networking that can exchange IP addresses - carry data by multiple network layer protocols - and support different app. protocols.






38. Associates a MAC address with a given IP address - reverse ARP






39. Transport layer protocol that services a request without requiring a verified session and without guaranteeing delivery data






40. Device that connects network segments and directs data based on information in the data packet






41. Name Of Layer 6






42. Using part of a leased line






43. Type of interference caused by signals traveling on nearby wire pairs infringing on another pair's signal






44. A shell protocol that enables systems to use various authenticaion mechanisms.






45. Encrypts






46. Ppp tunneling protocol






47. Gigabit Interface Converter - Plugs in to an interface on a switch






48. CSU






49. A poplar alternative to FTP is NFS software offered by Sun Microsystems - which uses Sun's remotr procedure call specification via TCP port 111.






50. Knows which VLAN a stream of data belongs to by reading a tad added to each frames header
