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






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






3. The process of simulating a 2600Hz frequency tone - which allowed attackers to gain free long distance phone service.






4. Wireless standard that will improve security of wireless communication






5. Type of topology that uses a bus that does not have a one linear cable - but instead uses branches of cables. Commonly used in Ethernet.






6. More complexity and drastically increases the difficultly of access control. Many different devices - services - and users make it difficult to know which entities to trust and to what degree.






7. OSI layer that prepares data for the network medium by framing it into LAN/WAN frames. Defines how the physical layer transmits the network packets. Protocols at this layer ARP (Address Resolution Protocol) - RARP (Reverse Address Resolution Protocol






8. 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-






9. Provides high-speed access - up to 50 Mbps - to the Internet through existing cable coaxial and fiber lines. Major security concern is the fact that neighbors use the same coaxial network and can monitor each others traffic.






10. VPN protocol that works at the network layer - handles multiple connections - provides secure authentication and encryption. Tunnel mode option (payload and header encrypted) - or transport mode (only payload is encrypted).






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






12. Encapsulation protocol for telecommunication connections. Replaced SLIP and is ideal for connection different types of devices over serial lines.






13. Works like a private line for a customer with an agreed upon bandwidth. Path is programmed into the WAN devices.






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






15. Device used within companies to provide multiple services to users throughout a building or facility. Example - dialing 9 to place outbound phone calls. Security concerns: default configurations and passwords - maintenance modems disabled - unused co






16. Most expensive type of WAN connection because the fee is based on distance between the two points rather than the amount of bandwidth used. Examples - T1 and T3.






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






18. 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.






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






20. In the OSI layer 5 - these are the types of what?






21. Type of network layout that is a large geographical region connecting more that one LAN.






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






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






24. 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.






25. Type of cable that is more expensive than UTP and STP - more resistant to EMI - can carry baseband and board band technologies.






26. Blue tooth vulnerability where an attacker sends messages to a receiver that is in discovery mode.






27. Firewall that does not require a proxy for each service; does not provide detailed access control; but does provide for a wider range of protocols.






28. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






29. Transmits high speed bandwidth over phone lines. Provides data rates up to 52 Mpbs using line of 1000 feet or less. Must be within 2.5 miles of a central office.






30. Type of network layout that separates and group computers logically.






31. Both directions - only one application can send information at a time






32. 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.






33. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






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






35. Spam over IM






36. Type of network device that allows different network segments and/or systems to communicate. When communication takes place - a dedicated connection is set up - so collision and broadcast data is not available to other devices. Combined repeater (hub






37. Wireless LAN standard that operates in a 5Ghz range - 54Mpbs - and uses OFDM spread spectrum.






38. OSI layer that formats data into a standardized format and deals with the syntax of data - not the meaning. Example formats are ASCII - GIF - JPG - MPEG.






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






40. 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






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






42. The original technique to digitized voice with 8 bits of sampling 8 -000 times per second - which yields 64 Kbps for one voice channel.






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






44. If the packet header information is used to determine destinations rather than the routes configured into the router. Packets with this information should be dropped.






45. Wireless LAN standard that operates in a 2.4Ghz range - 11Mbps - DSSS






46. 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.






47. Type of network device that divides networks into more controllable segments to ensure more efficient use of bandwidth. Works at the data link layer and understands MAC addresses - not IP addresses.






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






49. Type of backbone network that joins together LAN to other LANs and WANs to LANs - etc. Typically known as Synchronous Optical Networks (SONETS) or FDDI rings.






50. Type of firewall that lies between the perimeter router and and LAN.
