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 outlines wireless personal area network (WPAN) technologies.






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






3. Wireless standard that will improve security of wireless communication






4. Protocol based on the SDLC protocol - except it is an open protocol - supports full-duplex connections - and provides a higher throughput. It also provides polling - which enables secondary units to communicate with primary units.






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






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






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






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






9. 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.






10. 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.






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






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






13. 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






14. Standard that addresses wireless MAN technologies.






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






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






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






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






19. 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.






20. 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.






21. 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.






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






23. 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.






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






25. 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.






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






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






28. 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.






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






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






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






32. Type of switch that uses tags that are assigned to each destination network. The network compares the tag with its tag information base - appends the appropriate tag - and forwards to the next switch. This increases the transmission speed - allows la






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






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






35. 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.






36. The original technique to digitized voice with 8 bits of sampling 8 -000 times per second - which yields 64 Kbps for one voice channel.






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






38. 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.






39. Proprietary protocol that enables secondary devices to communicate with primary stations or mainframes in an IBM architecture. Developed in the mid-70's for use in a systems network architecture (SNA) environment. First synchronous - link layer - bit






40. 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.






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






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






43. 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.






44. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






45. Wireless LAN standard that operates in a 5Ghz range - 54Mpbs - and uses OFDM spread spectrum.






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






47. 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.






48. 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.






49. 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.






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