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. A simplified version of X.25 - without the error checking that was done on the network. It handles error checking at the end node - which helps improve speed dramatically.






2. Spam over IM






3. 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.






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






5. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






8. Type of wireless security standard that uses AES in CBC mode.






9. 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.






10. 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.






11. 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.






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






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






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






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






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






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






18. 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






19. VPN protocol that can run in other networks (frame relay - X.25 - ATM). Does not provide encryption - lacks the security to be called a true "VPN" solution.






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






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






22. 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.






23. 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.






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






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






26. 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






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






28. Strengths of a type of Stateful Firewall: High security - better performance than an application firewall. Weaknesses include more complex - ___________ - if rebooted all information is lost.






29. 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.






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






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






32. 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.






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






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






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






36. 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.






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






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






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






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






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






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






43. Protocol stack used instead of TCP/IP on wireless devices. The "gap" in this protocol involves translating its secure traffic to SSL or TLS - which is typically done by a 3rd party.






44. 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).






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






46. 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.






47. 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.






48. 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






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






50. 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
