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






2. 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






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






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






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






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






7. Dynamically builds ACL's to allow internal systems to communicate with external systems. Once the connection is finished - the ACL is removed from the list. 4th generation firewall.






8. 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.






9. Strengths of a type of firewall: Better security than packet filtering. Looks at all info in the packet - up to the application layer. Breaks the connection between trusted and untrusted systems. Weaknesses include limited number of applications supp






10. Wireless standard that will improve security of wireless communication






11. Security wireless standard that rotates encryption keys - stronger IV values - MAC codes for packet integrity. Works in combination with WEP.






12. 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.






13. Both directions - both applications can send information at a time. Session Layer Communication Modes






14. 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.






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






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






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






18. 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.






19. 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.






20. 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.






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






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






23. 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






24. OSI layer that provides physical connections for transmission and performs the electrical encoding of data. This layer transforms bits to electrical signals. Protocols at this level HSSI (High Speed Serial Interface) - X.21 - EIA/TIA 232 and 449.






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






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






28. 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.






29. 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).






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






31. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






33. 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.






34. 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.






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






36. 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.






37. 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.






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






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






40. 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.






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






42. The process of simulating a 2600Hz frequency tone - which allowed attackers to gain free long distance phone service.






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






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






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






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






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






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






49. 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.






50. Older LAN implementation that uses a token-passing technology. Can send a beacon frame to indicate that a certain computer is failing and its neighbors should reconfigure and work around the detected fault.
