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. 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.






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






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






4. 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






5. 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.






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






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






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






9. 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.






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






11. 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.






12. 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.






13. 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).






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






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






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. 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.






18. 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.






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






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






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






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






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






26. 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.






27. 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.






28. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






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






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. New variant to traditional email spam on VoIP networks.






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






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






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






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






38. Type of host that is locked down - hardened - system. Systems installed in the DMZ (firewalls - servers) should be installed on this type of host.






39. 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






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






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






42. OSI layer that prepares data for the network medium by framing it into LAN/WAN frames. Defines how the physical layer transmits the network packets. Protocols at this layer ARP (Address Resolution Protocol) - RARP (Reverse Address Resolution Protocol






43. 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.






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






45. Wireless LAN standard that operates in a 2.4Ghz range - 11Mbps - DSSS






46. More complexity and drastically increases the difficultly of access control. Many different devices - services - and users make it difficult to know which entities to trust and to what degree.






47. 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.






48. 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






49. Network segment name for a DMZ created by two physical firewalls.






50. 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.
