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






2. 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.






3. 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.






4. 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.






5. 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-






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






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






8. 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.






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






10. 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.






11. 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.






12. 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.






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






14. The original technique to digitized voice with 8 bits of sampling 8 -000 times per second - which yields 64 Kbps for one voice channel.






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






16. 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.






17. 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.






18. 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.






19. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






20. Type of network layout that separates and group computers logically.






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






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






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






24. 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.






25. 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.






26. If the packet header information is used to determine destinations rather than the routes configured into the router. Packets with this information should be dropped.






27. 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.






28. 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.






29. Standard that addresses wireless MAN technologies.






30. 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.






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






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






33. 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.






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






35. 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.






36. Type of cabling problem where data is corrupted going from end to end due to surrounding devices.






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






38. 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).






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






40. 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).






41. Communication devices that determine synchronization scheme before data transmission.






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






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






44. 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.






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






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






47. 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.






48. 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.






49. A Temporary circuit set up for a single connection. Set up and torn down as they are needed.






50. 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.
