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. 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.






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






3. Device used within companies to provide multiple services to users throughout a building or facility. Example - dialing 9 to place outbound phone calls. Security concerns: default configurations and passwords - maintenance modems disabled - unused co






4. 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.






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






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






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






8. 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.






9. 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.






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






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






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






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






14. 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.






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






16. Type of firewall that keeps track of each communication session. It must maintain a state table that contains data about each connection. 3rd generation firewall - runs at the network layer.






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






18. 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.






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






20. 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.






21. 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






22. 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.






23. 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.






24. 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.






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






26. 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






27. Wireless standard that will improve security of wireless communication






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






29. Layer 3 - layer 4 - and other layer switches have more enhanced functionality than layer 2 switches. Combines switching and routing technologies - packet inspection - traffic prioritization - and quality of service (QoS).






30. 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.






31. 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.






32. 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






33. Premium service offered by service providers in frame relay networks that guarantees a company a specified amount of bandwidth.






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






35. 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.






36. Server that can be configured to hang up and call back remote users - but this can be compromise by enabling call forwarding.






37. 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.






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






39. 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.






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






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






42. Type of firewall that lies between the perimeter router and and LAN.






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






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






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






46. 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.






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






48. 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.






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






50. 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.
