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 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.






2. Most commonly used LAN implementation today. Considered a "chatty" protocol because it allows all systems to hear each other's broadcasts. Has many collisions because all systems share the same medium. Can operate at 10 to 1000 Mbps.






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






4. 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.






5. Wireless standard that will improve security of wireless communication






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






7. 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.






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






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






10. Standard that addresses wireless MAN technologies.






11. 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.






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






13. Type of topology that Uses linear single cable for all computers attached. All traffic travels full cable and can be viewed by all other computers.






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






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






16. 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.






17. 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.






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






19. A Temporary circuit set up for a single connection. Set up and torn down as they are needed.






20. Strengths of a type of firewall: Better security than packet filtering. Looks at all info in the packet - up to the application layer. Breaks the connection between trusted and untrusted systems. Weaknesses include limited number of applications supp






21. 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.






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






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






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






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






26. 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.






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






28. 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.






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






30. Spam over IM






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






32. Problems: Central device is a single point of failure.






33. 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.






34. Wireless communication that applies sub-bits to a message (chips) and the receiver uses the chips to re-assemble the message based on the chipping code. It uses all available bandwidth - high throughput of 11Mbps.






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






36. 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.






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






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






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






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






41. 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.






42. 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.






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






44. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






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






47. 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






48. 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.






49. 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.






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