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






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






3. 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.






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






5. 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






6. 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.






7. Spam over IM






8. 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.






9. 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.






10. OSI layer that has services and protocols required by the user's applications for network functionality. Example protocols include HTTP - SMTP - FTP - Telnet.






11. 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.






12. Most commonly used LAN implementation today. Considered a "chatty" protocol because it allows all systems to hear each other's broadcasts. Has many collisions because all systems share the same medium. Can operate at 10 to 1000 Mbps.






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






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






15. 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.






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






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






18. 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.






19. Wireless standard that will improve security of wireless communication






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






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






22. 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.






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






24. 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.






25. 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.






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






27. Protocol that addresses vulnerabilities found in PAP. Uses challenge/response mechanism to authenticate the user instead of sending password.






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






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






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






31. In the OSI layer 5 - these are the types of what?






32. 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.






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






34. 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.






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






36. 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.






37. 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.






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






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






40. 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.






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






42. Protocol that transfers data in fixed cells (53 bytes) - is a WAN technology - and transmits data at very high rates. Supports voice - data - and video applications.






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






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






45. 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.






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






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






48. 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.






49. 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.






50. OSI layer that provides end to end transmission between computer systems. Protocols that use this layer are TCP (Transmission Control Protocol) - UDP (User Datagram Protocol) - SPX (Sequenced Packet Exchange) - and SSL.
