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 the device does not need to provide a key for authentication. Usually - only the SSID is required and plaintext transmission occurs.






2. 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.






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






4. VPN protocol that works at the network layer - handles multiple connections - provides secure authentication and encryption. Tunnel mode option (payload and header encrypted) - or transport mode (only payload is encrypted).






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






6. 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






7. 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.






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






9. 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.






10. 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.






11. 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.






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






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






14. 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.






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






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






17. 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.






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






19. 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.






20. 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.






21. Protocol based on the first version - however this version allows for fixed bandwidth to be allocated for specific applications.






22. 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.






23. 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.






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






25. Protocol that resolves host names into IP addresses and has distributed databases all over the Internet to provide name resolution.






26. 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






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






28. 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.






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






30. Type of authentication protocol that provides a framework to enable may types of authentication techniques to be used during PPP connections. It extends the possibilities to one-time passwords - token cards - biometrics - Kerberos - and digital certi






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






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






33. 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.






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






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






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






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






38. 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.






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






40. 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.






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






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






43. 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.






44. Type of LAN and MAN technology - usually used for backbones - that uses token-passing technology and has redundant rings in case the primary ring goes down.






45. 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.






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






47. 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.






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






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






50. 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.
