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. Standard that addresses wireless MAN technologies.






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






3. 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.






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






5. These are used to connect multiple switches for traffic of the same classification. Example - two voice switches at a local phone company's central office.






6. 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






7. 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.






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






9. 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.






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






11. 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.






12. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






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






15. Protocol that is reliable and connection-oriented - which means it ensures delivery through acknowledgements - sequencing - detection and correction.






16. 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-






17. Communication devices that are not synchronized - meaning all devices can send data at will - send a sequence of bits framed with a start and stop bit.






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






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






20. 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






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






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






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






24. 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.






25. 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.






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






27. 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.






28. 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.






29. 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.






30. Application layer request/response protocol widely used for VoIP communication sessions. Transported by UDP - makes use of TCP - and is vulnerable to sniffing attacks.






31. Type of switch that uses tags that are assigned to each destination network. The network compares the tag with its tag information base - appends the appropriate tag - and forwards to the next switch. This increases the transmission speed - allows la






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






33. 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






34. OSI layer that formats data into a standardized format and deals with the syntax of data - not the meaning. Example formats are ASCII - GIF - JPG - MPEG.






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






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






37. 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.






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






39. 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.






40. 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.






41. 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.






42. 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.






43. This network technology determines which system will send data based on which one has the token.






44. A WAN protocol that works at the data link layer and performs packet switching. Economical choice because the fee is based on bandwidth usage rather than a dedicated pipeline.






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






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






47. Wireless communication that applies sub-bits to a message (chips) and the receiver uses the chips to re-assemble the message based on the chipping code. It uses all available bandwidth - high throughput of 11Mbps.






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






49. 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.






50. 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.
