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






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






3. 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.






4. 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






5. 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.






6. 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.






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






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






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






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






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






12. 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.






13. Type of topology where computers all are connected to each other - which provides redundancy.






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






15. 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.






16. Network cabling that is placed in these types of areas must meet a specific fire rating. These cables typically have a jacked cover made of fluoropolymers.






17. 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.






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






19. Spam over IM






20. Type of firewall that Inspects incoming/outgoing messages for malicious information. If approved - transfers an isolated copy from one network to another. 2nd generation firewall.






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






22. 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.






23. 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.






24. 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.






25. 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.






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






27. 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.






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






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






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






31. 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.






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






33. 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.






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






35. Layer 3 - layer 4 - and other layer switches have more enhanced functionality than layer 2 switches. Combines switching and routing technologies - packet inspection - traffic prioritization - and quality of service (QoS).






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






37. 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.






38. 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.






39. 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.






40. 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.






41. Type of network device that is the simplest type of connectivity because it only repeats and amplifies electric signals between cable segments. Works at the physical layer.






42. 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.






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






44. Type of cable where STP and UTP (shielded and unshielded) cables are the most popular - cheapest - and easiest to work with. However - easiest to tap into - have cross talk issues - and are vulnerable to electromagnetic interference (EMI).






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






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






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






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






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






50. OSI layer that has services and protocols required by the user's applications for network functionality. Example protocols include HTTP - SMTP - FTP - Telnet.
