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






2. Wireless standard that will improve security of wireless communication






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






4. 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.






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. A packet switching technology that is used by telecommunication services for data-only traffic. It is a subscriber based service that operates within the network and data link layers.






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






8. OSI layer that sets up - maintains - and breaks down the dialog (session) between two applications. Controls dialog organization and synchronization. Protocols that work at this layer are NFS (Network File System) - SQL - NetBIOS - RPC.






9. 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.






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






11. A WAN protocol that works at the data link layer and performs packet switching. Economical choice because the fee is based on bandwidth usage rather than a dedicated pipeline.






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






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






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






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






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






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






18. 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.






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






20. 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.






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






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






23. 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






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






25. 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.






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






27. 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.






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






29. VPN protocol that works at the data link layer - can only run in IP networks - and provides encryption and encapsulation. This is Microsoft's VPN solution.






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






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






32. 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.






33. 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.






34. Altering an ARP table so an IP address is mapped to a different MAC address. Results in traffic being routed to an attacker's computer.






35. 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.






36. 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.






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






38. 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






39. 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.






40. 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.






41. 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).






42. 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.






43. These are used to connect multiple switches for traffic of the same classification. Example - two voice switches at a local phone company's central office.






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






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






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






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






49. 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-






50. Communication devices that are not synchronized - meaning all devices can send data at will - send a sequence of bits framed with a start and stop bit.
