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






2. 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.






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






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






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






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






7. 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.






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






9. 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.






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






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






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






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






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






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






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






17. 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.






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






19. 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






20. 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.






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






22. OSI layer that provides routing - addressing - and fragmentation of packets. This layer can determine alternative routes to avoid network congestion. Protocols that use this layer are IP - ICMP - RIP - OSPF (Open Shortest Path First) - BGP (Border Ga






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






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






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






26. Server that can be configured to hang up and call back remote users - but this can be compromise by enabling call forwarding.






27. 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.






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






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






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






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






32. 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






33. Type of topology where all computers are connected by a unidirectional transmission link - and the cable is in a closed loop.






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






35. Type of firewall that is a proxy-based firewall solution. It is circuit-based and does not provide any application-based proxies.






36. 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.






37. OSI layer that provides physical connections for transmission and performs the electrical encoding of data. This layer transforms bits to electrical signals. Protocols at this level HSSI (High Speed Serial Interface) - X.21 - EIA/TIA 232 and 449.






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






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






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






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






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






43. Type of firewall that can be compromised if the OS does not have packet forwarding or routing turned off.






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






45. 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.






46. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






47. 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.






48. Protocol where all computers compete for the shard network cable - listen to learn when they can transmit data - susceptible to data collisions. Used by Ethernet.






49. 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.






50. 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.
