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. 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.






2. Wireless standard that will improve security of wireless communication






3. Protocol that is used by remote users to authenticate over PPP lines. Sends passwords over clear text. Vulnerable to MITM attacks.






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. Combines voice and data over the same IP network media and protocol. Reduces the cost of implementing and maintaining two different networks.






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






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






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






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






10. Spam over IM






11. 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






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






13. A technique that allows multiple layers of nesting. Example - IPSec tunnel can originate or terminate at a different IPSec site along the way.






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






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






16. 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.






17. Wireless LAN standard that operates in a 5Ghz range - 54Mpbs - and uses OFDM spread spectrum.






18. 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.






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






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






21. 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.






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






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






24. 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.






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






26. 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.






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






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






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






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






31. 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.






32. Faster because processing is done in the kernel. One network stack is created for each packet. 5th generation firewall - runs at the application layer.






33. 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






34. Protocol that translates a MAC address into an IP address.






35. Standard that outlines wireless personal area network (WPAN) technologies.






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






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






38. 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).






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






40. VPN protocol that works at the network layer - handles multiple connections - provides secure authentication and encryption. Tunnel mode option (payload and header encrypted) - or transport mode (only payload is encrypted).






41. Wireless communication that splits total amount of bandwidth into smaller sub-channels. Send and receiver work in one of the channels for a period of time - and then move into a different channel. It uses a portion of the bandwidth - throughput of 1-






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






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






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






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






47. 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.






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






49. 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.






50. 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.
