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






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






3. 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.






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






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






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






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






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






9. 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.






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






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






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






13. Protocol where all computers compete for the shard network cable - listen to learn when they can transmit data - susceptible to data collisions. Used by Ethernet.






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






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






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






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






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






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






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. 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.






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






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






24. Most expensive type of WAN connection because the fee is based on distance between the two points rather than the amount of bandwidth used. Examples - T1 and T3.






25. 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.






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






27. 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-






28. Type of cable that is more expensive than UTP and STP - more resistant to EMI - can carry baseband and board band technologies.






29. 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






30. Wireless standard that will improve security of wireless communication






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






32. 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.






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






34. 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.






35. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






37. 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).






38. 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.






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






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






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






42. 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.






43. 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.






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






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






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






47. Standard that addresses wireless MAN technologies.






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






49. Wireless LAN standard. Variations include 802.11a - b - f - g - and i. Commonly accepts are 802.11b and g.






50. Provides high-speed access - up to 50 Mbps - to the Internet through existing cable coaxial and fiber lines. Major security concern is the fact that neighbors use the same coaxial network and can monitor each others traffic.
