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






2. Spam over IM






3. Problems: Requires more expense in cabling and extra effort to track down cable faults.






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






5. 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.






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






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






8. 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.






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






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






11. 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.






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






13. Standard that addresses wireless MAN technologies.






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






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






16. 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.






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






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






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






20. 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.






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






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






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






24. 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.






25. 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.






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






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






28. 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).






29. Uses tunneling protocols and encryption to provide a secure network connection between two network hosts. Private and secure connections can be made across an unsecured network. Example protocols are PPTP - L2TP - and IPSec.






30. 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.






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






32. 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.






33. 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.






34. 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.






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






36. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






37. 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.






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






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






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






41. 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.






42. 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.






43. 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).






44. The well known values range from 0-1023. FTP runs on 20 and 21 - SMTP runs on 25 - TFTP runs on 69 - DNS runs on 53 - HTTP runs on 80 - HTTPS runs on 443 - SNMP runs on 161.






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






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






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






48. Wireless standard that will improve security of wireless communication






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






50. 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.
