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. 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.






2. Type of ethernet implementation that uses a standard coaxial cable with a maximum cable length of 185 meters. 10Mbps.






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






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






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






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






7. 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.






8. 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.






9. Wireless standard that will improve security of wireless communication






10. Protocol that increases address size from 32 bits to 128 bits






11. Network cabling that is placed in these types of areas must meet a specific fire rating. These cables typically have a jacked cover made of fluoropolymers.






12. 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






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






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






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






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. Both directions - both applications can send information at a time. Session Layer Communication Modes






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






19. A technique that allows multiple layers of nesting. Example - IPSec tunnel can originate or terminate at a different IPSec site along the way.






20. Dynamically builds ACL's to allow internal systems to communicate with external systems. Once the connection is finished - the ACL is removed from the list. 4th generation firewall.






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






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






23. Security wireless standard that rotates encryption keys - stronger IV values - MAC codes for packet integrity. Works in combination with WEP.






24. 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.






25. A simplified version of X.25 - without the error checking that was done on the network. It handles error checking at the end node - which helps improve speed dramatically.






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






27. 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.






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






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






30. Strengths of a type of firewall: application independence - high performance - and scalability. Weaknesses include low security - no protection above the network layer.






31. Type of topology that where all computers are connected to a central device (AKA hub) - which provides more resilience for the network.






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






34. Wireless communication that distributes individual signals across the allocated frequencies.






35. 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.






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






37. Type of wireless authentication where a shared WEP key is used to encrypt a nonce for authentication.






38. 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.






39. 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.






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






41. Spam over IM






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






43. In a token ring network - each computer is connected to this - which acts as a central hub.






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






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






46. 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.






47. Type of cabling problem signals from one wire crossing over to another wire.






48. OSI layer 2 Sub-layers. The first provides a standard interface for the network protocol being used. The second provides a standard interface for the physical layer protocol being used.






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






50. This dedicated connection provides 45Mbps of bandwidth over 28 T1 lines and 672 time divided channels.
