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. 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






3. 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.






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






5. Type of ethernet implementation that uses a standard coaxial cable with a maximum cable length of 185 meters. 10Mbps.






6. Standard that addresses wireless MAN technologies.






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






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






9. In a token ring network - each computer is connected to this - which acts as a central hub.






10. 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.






11. 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.






12. 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.






13. 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.






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






15. 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






16. Uses tunneling protocols and encryption to provide a secure network connection between two network hosts. Private and secure connections can be made across an unsecured network. Example protocols are PPTP - L2TP - and IPSec.






17. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






18. 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.






19. 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.






20. 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.






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






23. 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.






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






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






26. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






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






28. 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.






29. Identifys a WLAN. Can be used to segment environments into different WLANS.






30. 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






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






32. 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.






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






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






35. 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.






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






37. 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.






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






39. Protocol that transfers data in fixed cells (53 bytes) - is a WAN technology - and transmits data at very high rates. Supports voice - data - and video applications.






40. 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.






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






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






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






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






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






46. Protocol that resolves host names into IP addresses and has distributed databases all over the Internet to provide name resolution.






47. 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.






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






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






50. Strengths of a type of firewall: application independence - high performance - and scalability. Weaknesses include low security - no protection above the network layer.
