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. 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.






3. 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.






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






5. 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.






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






7. 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.






8. Type of topology that Uses linear single cable for all computers attached. All traffic travels full cable and can be viewed by all other computers.






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






10. Network cabling that is placed in these types of areas must meet a specific fire rating. These cables typically have a jacked cover made of fluoropolymers.






11. 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.






12. Altering an ARP table so an IP address is mapped to a different MAC address. Results in traffic being routed to an attacker's computer.






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






14. 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.






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






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






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






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






19. 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.






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






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






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






23. Network where a virtual connection that acts like a dedicated link between two systems is set up. Traffic travels in a predictable and constant manner. Example - telephone.






24. Standard that addresses wireless MAN technologies.






25. 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.






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






27. Type of topology where computers all are connected to each other - which provides redundancy.






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






29. 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.






30. 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






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






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






33. 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.






34. 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).






35. Security wireless standard that enables data transfers to be encrypted. Static encryption keys among clients - short 40 bit keys - RC4 encryption - ineffective use of 24 bit IV's - and no packet integrity.






36. 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






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






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






39. 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.






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






41. 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






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






43. Proprietary protocol that enables secondary devices to communicate with primary stations or mainframes in an IBM architecture. Developed in the mid-70's for use in a systems network architecture (SNA) environment. First synchronous - link layer - bit






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






45. This dedicated connection provides 45Mbps of bandwidth over 28 T1 lines and 672 time divided channels.






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






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






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






49. Type of firewall that Inspects incoming/outgoing messages for malicious information. If approved - transfers an isolated copy from one network to another. 2nd generation firewall.






50. 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
