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






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






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






4. 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.






5. 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.






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






7. Type of cabling problem where loss of signal strength occurs as it travels due to cable exceeding its recommended length.






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






9. Encapsulation protocol for telecommunication connections. Replaced SLIP and is ideal for connection different types of devices over serial lines.






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






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






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






13. 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.






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






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






16. 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.






17. 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






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






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






20. Spam over IM






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






22. 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.






23. 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.






24. Wireless standard that will improve security of wireless communication






25. 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.






26. 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.






27. Application layer request/response protocol widely used for VoIP communication sessions. Transported by UDP - makes use of TCP - and is vulnerable to sniffing attacks.






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






29. 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.






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






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






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






34. 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.






35. 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.






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






37. 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.






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






39. SMTP server that is configured for sending email from any source to and destination.






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






41. 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.






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






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






44. 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.






45. 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.






46. 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






47. 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.






48. 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.






49. 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.






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