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. Standard that addresses wireless MAN technologies.






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






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






4. An older protocol that was used by ISP's to encapsulate data to be sent over dial up connections






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






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






7. 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.






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






9. OSI layer that has services and protocols required by the user's applications for network functionality. Example protocols include HTTP - SMTP - FTP - Telnet.






10. Type of host that is locked down - hardened - system. Systems installed in the DMZ (firewalls - servers) should be installed on this type of host.






11. Strengths of a type of Stateful Firewall: High security - better performance than an application firewall. Weaknesses include more complex - ___________ - if rebooted all information is lost.






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






13. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






15. Network where a dedicated virtual link is not set up - and packets can use many different dynamic paths to get to the same destination. This causes variable delays. Examples are frame relay and X.25






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






17. 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.






18. Used when companies do not want systems to know internal hosts IP addresses. Enables companies to use private - nonroutable IP addresses.






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






20. Protocol based on the first version - however this version allows for fixed bandwidth to be allocated for specific applications.






21. 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.






22. 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-






23. Type of network that allows large IP ranges to be divided into smaller - logical - and easier to maintain network segments.






24. This is a standard for fiber-optic cabling and uses self-healing network rings. This standard describes the interfaces that can be used over fiber lines and the signaling that can be employed. Works at the physical layer of the OSI model.






25. Protocol for allowing multi-cast (one to many) communication






26. 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.






27. 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).






28. Wireless LAN standard. Variations include 802.11a - b - f - g - and i. Commonly accepts are 802.11b and g.






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






30. Used when a LAN device needs to communicate with WAN devices over telephone lines. Ensures the necessary electrical signaling and format are used. Interfaces with Data Terminal Equipment (DTE) and Data Circuit-Terminal Equipment (DCE).






31. VPN protocol that can run in other networks (frame relay - X.25 - ATM). Does not provide encryption - lacks the security to be called a true "VPN" solution.






32. Spam over IM






33. 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.






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






35. The well known values range from 0-1023. FTP runs on 20 and 21 - SMTP runs on 25 - TFTP runs on 69 - DNS runs on 53 - HTTP runs on 80 - HTTPS runs on 443 - SNMP runs on 161.






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






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






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






39. 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.






40. 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.






41. Protocol that is reliable and connection-oriented - which means it ensures delivery through acknowledgements - sequencing - detection and correction.






42. Protocol that is used by remote users to authenticate over PPP lines. Sends passwords over clear text. Vulnerable to MITM attacks.






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






45. Type of topology where computers all are connected to each other - which provides redundancy.






46. OSI layer that provides end to end transmission between computer systems. Protocols that use this layer are TCP (Transmission Control Protocol) - UDP (User Datagram Protocol) - SPX (Sequenced Packet Exchange) - and SSL.






47. Standard for transmitting data across the Internet. One is reliable and connection oriented. The other is unreliable and connectionless.






48. Type of firewall that keeps track of each communication session. It must maintain a state table that contains data about each connection. 3rd generation firewall - runs at the network layer.






49. Wireless standard that will improve security of wireless communication






50. 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.
