CISSP Telecom And Network Security

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. Protocol that addresses vulnerabilities found in PAP. Uses challenge/response mechanism to authenticate the user instead of sending password.






2. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






3. Premium service offered by service providers in frame relay networks that guarantees a company a specified amount of bandwidth.






4. Standard that outlines wireless personal area network (WPAN) technologies.






5. SMTP server that is configured for sending email from any source to and destination.






6. Protocol that is best-effort - connectionless - and does not sent acknowledgements.






7. Problems: If one station experiences a problem - it can negatively affect surrounding computers on the same ring.






8. Type of firewall that Inspects incoming/outgoing messages for malicious information. If approved - transfers an isolated copy from one network to another. 2nd generation firewall.






9. Protocol stack used instead of TCP/IP on wireless devices. The "gap" in this protocol involves translating its secure traffic to SSL or TLS - which is typically done by a 3rd party.






10. This dedicated connection provides up to 1.544 Mbps bandwidth over 1 T1 and 24 time divided channels.






11. Wireless communication that splits total amount of bandwidth into smaller sub-channels. Send and receiver work in one of the channels for a period of time - and then move into a different channel. It uses a portion of the bandwidth - throughput of 1-






12. Type of wireless authentication where the device does not need to provide a key for authentication. Usually - only the SSID is required and plaintext transmission occurs.






13. Type of ethernet implementation that uses twisted-pair copper wiring and transmits at 100Mbps.






14. Type of cabling problem where data is corrupted going from end to end due to surrounding devices.






15. Type of network device that is the simplest type of connectivity because it only repeats and amplifies electric signals between cable segments. Works at the physical layer.






16. Malware attack that sends commands inside of an ICMP packet.






17. Combines voice and data over the same IP network media and protocol. Reduces the cost of implementing and maintaining two different networks.






18. Network segment name for a DMZ created by two physical firewalls.






19. Security wireless standard that enables data transfers to be encrypted. Static encryption keys among clients - short 40 bit keys - RC4 encryption - ineffective use of 24 bit IV's - and no packet integrity.






20. Protocol that translates a MAC address into an IP address.






21. Network where a virtual connection that acts like a dedicated link between two systems is set up. Traffic travels in a predictable and constant manner. Example - telephone.






22. Developed to replace the aging telephone and analog systems. BRI rate that uses two B channels (send/receive) - and one D channel (control information) - and PRI rate that uses up to 23 B channels. Supports voice - data - and video. Provides up to 1.






23. Older LAN implementation that uses a token-passing technology. Can send a beacon frame to indicate that a certain computer is failing and its neighbors should reconfigure and work around the detected fault.






24. Protocol that resolves host names into IP addresses and has distributed databases all over the Internet to provide name resolution.






25. Spam over IM






26. Type of authentication protocol that provides a framework to enable may types of authentication techniques to be used during PPP connections. It extends the possibilities to one-time passwords - token cards - biometrics - Kerberos - and digital certi






27. Problems: Requires more expense in cabling and extra effort to track down cable faults.






28. Type of cabling problem where loss of signal strength occurs as it travels due to cable exceeding its recommended length.






29. Type of cable that carries data as light waves - expensive - can transmit data at high speeds - difficult to tap into - and is resistant to EMI. Most secure cabling option - but vulnerable to dispersion.






30. Standard that addresses wireless MAN technologies.






31. Protocol that works at the network layer and informs hosts - routers - and devices of network or computer problems. It is the major component of the ping utility.






32. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






33. Type of wireless security standard that uses AES in CBC mode.






34. Faster because processing is done in the kernel. One network stack is created for each packet. 5th generation firewall - runs at the application layer.






35. This network technology determines which system will send data based on which one has the token.






36. Type of network device that links 2 or more network segments - where each segment can function as an independent network. Works at the network layer - works with IP addresses - and has more network knowledge than the other hardware.






37. VPN protocol that works at the data link layer - can only run in IP networks - and provides encryption and encapsulation. This is Microsoft's VPN solution.






38. As they travel down the OSI model on the source computer - each layer adds its own information so the corresponding layer on the destination machine knows how to process the data.






39. Type of firewall that is also know as a screening router and is accomplished by ACL's (Lines of text called rules). Traffic can be filtered by address - ports - and protocol types. 1st generation firewall - runs at the network layer.






40. Communication devices that determine synchronization scheme before data transmission.






41. Layer 3 - layer 4 - and other layer switches have more enhanced functionality than layer 2 switches. Combines switching and routing technologies - packet inspection - traffic prioritization - and quality of service (QoS).






42. New variant to traditional email spam on VoIP networks.






43. Type of LAN and MAN technology - usually used for backbones - that uses token-passing technology and has redundant rings in case the primary ring goes down.






44. Uses tunneling protocols and encryption to provide a secure network connection between two network hosts. Private and secure connections can be made across an unsecured network. Example protocols are PPTP - L2TP - and IPSec.






45. Set of rules that dictates how computer communicate over networks.






46. Protocol that translates IP address into a MAC address (physical Ethernet address)






47. Protocol based on the SDLC protocol - except it is an open protocol - supports full-duplex connections - and provides a higher throughput. It also provides polling - which enables secondary units to communicate with primary units.






48. Type of firewall that looks at header information to make decisions on whether a packet is deemed acceptable. This type does not look as deep within the packet as an application level proxy - runs at the session layer.






49. Type of ethernet implementation that uses a thicker coaxial cable - which allows a longer cable length to be used.






50. Type of switch that uses tags that are assigned to each destination network. The network compares the tag with its tag information base - appends the appropriate tag - and forwards to the next switch. This increases the transmission speed - allows la
