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. 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.






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






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






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






5. 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.






6. An older protocol that was used by ISP's to encapsulate data to be sent over dial up connections






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






8. OSI layer that provides routing - addressing - and fragmentation of packets. This layer can determine alternative routes to avoid network congestion. Protocols that use this layer are IP - ICMP - RIP - OSPF (Open Shortest Path First) - BGP (Border Ga






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






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






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






12. 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.






13. 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






14. 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.






15. Spam over IM






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






17. 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.






18. Wireless LAN standard that operates in a 2.4Ghz range - 11Mbps - DSSS






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






20. 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.






21. 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.






22. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






24. Type of firewall that is also know as a screening router and is accomplished by ACL's (Lines of text called rules). Traffic can be filtered by address - ports - and protocol types. 1st generation firewall - runs at the network layer.






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






26. 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.






27. 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.






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






29. 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






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. 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.






32. 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).






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






34. Protocol that translates IP address into a MAC address (physical Ethernet address)






35. 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.






36. 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.






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






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






39. Both directions - both applications can send information at a time. Session Layer Communication Modes






40. 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.






41. 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).






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






43. 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.






44. 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






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






46. 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.






47. Type of firewall that is a proxy-based firewall solution. It is circuit-based and does not provide any application-based proxies.






48. 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






49. 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.






50. 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.
