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






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






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






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






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






7. 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.






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






9. 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.






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






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






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






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






14. 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.






15. 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.






16. Type of firewall that keeps track of each communication session. It must maintain a state table that contains data about each connection. 3rd generation firewall - runs at the network layer.






17. 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.






18. 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.






19. 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






20. 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.






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






22. 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.






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






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






25. 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.






26. 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






27. 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.






28. 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.






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






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






31. Developed to replace the aging telephone and analog systems. BRI rate that uses two B channels (send/receive) - and one D channel (control information) - and PRI rate that uses up to 23 B channels. Supports voice - data - and video. Provides up to 1.






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






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






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






35. 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.






36. 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.






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






38. Type of firewall that uses a proxy for each service and can understand and make decisions on the protocols used and the commands within those protocols - runs at the application layer.






39. 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.






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






41. 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






42. 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.






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






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






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






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






47. 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.






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






49. 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.






50. 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.
