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. Developed to replace the aging telephone and analog systems. BRI rate that uses two B channels (send/receive) - and one D channel (control information) - and PRI rate that uses up to 23 B channels. Supports voice - data - and video. Provides up to 1.






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






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






4. 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.






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






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






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






8. 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.






9. The original technique to digitized voice with 8 bits of sampling 8 -000 times per second - which yields 64 Kbps for one voice channel.






10. 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.






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






12. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






15. Wireless standard that will improve security of wireless communication






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






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






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






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






20. 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.






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






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






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 topology that uses a bus that does not have a one linear cable - but instead uses branches of cables. Commonly used in Ethernet.






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






26. Type of firewall that is also know as a screening router and is accomplished by ACL's (Lines of text called rules). Traffic can be filtered by address - ports - and protocol types. 1st generation firewall - runs at the network layer.






27. 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.






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






29. 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.






30. Type of network that allows large IP ranges to be divided into smaller - logical - and easier to maintain network segments.






31. New variant to traditional email spam on VoIP networks.






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






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






34. 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-






35. OSI layer that provides routing - addressing - and fragmentation of packets. This layer can determine alternative routes to avoid network congestion. Protocols that use this layer are IP - ICMP - RIP - OSPF (Open Shortest Path First) - BGP (Border Ga






36. 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).






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






38. 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.






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






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






41. Created because it was clear that available IP addresses were running out. Provides flexibility to increase or decrease the IP classes sizes as necessary.






42. 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.






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






44. Network where a dedicated virtual link is not set up - and packets can use many different dynamic paths to get to the same destination. This causes variable delays. Examples are frame relay and X.25






45. 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.






46. 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.






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. 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.






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






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