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. Wireless standard that will improve security of wireless communication






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






3. As they travel down the OSI model on the source computer - each layer adds its own information so the corresponding layer on the destination machine knows how to process the data.






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






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






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






7. 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.






8. 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.






9. 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.






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






11. SMTP server that is configured for sending email from any source to and destination.






12. OSI layer that prepares data for the network medium by framing it into LAN/WAN frames. Defines how the physical layer transmits the network packets. Protocols at this layer ARP (Address Resolution Protocol) - RARP (Reverse Address Resolution Protocol






13. 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.






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






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






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






17. 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.






18. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






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






20. 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






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






22. 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.






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






24. 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






25. 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.






26. 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.






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






28. 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






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






30. 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.






31. 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.






32. Type of topology that uses a bus that does not have a one linear cable - but instead uses branches of cables. Commonly used in Ethernet.






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






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






35. 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.






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






37. 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.






38. 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-






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






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






41. 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.






42. 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.






43. Protocol that is best-effort - connectionless - and does not sent acknowledgements.






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






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






46. 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.






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






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






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






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