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






2. 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.






3. 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.






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






5. 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.






6. 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.






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






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






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






10. 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.






11. Spam over IM






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






13. A packet switching technology that is used by telecommunication services for data-only traffic. It is a subscriber based service that operates within the network and data link layers.






14. Wireless standard that will improve security of wireless communication






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






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






17. 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.






18. 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.






19. 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.






20. 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.






21. 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.






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






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






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






25. 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.






26. 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.






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






28. OSI layer that sets up - maintains - and breaks down the dialog (session) between two applications. Controls dialog organization and synchronization. Protocols that work at this layer are NFS (Network File System) - SQL - NetBIOS - RPC.






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






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






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






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. 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.






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






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






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






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






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






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






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






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






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






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






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






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






47. 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






48. Firewall that does not require a proxy for each service; does not provide detailed access control; but does provide for a wider range of protocols.






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






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