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






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






3. 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.






4. 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.






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






6. 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.






7. 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.






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






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






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






11. 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.






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






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. 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.






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






17. 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.






18. Uses tunneling protocols and encryption to provide a secure network connection between two network hosts. Private and secure connections can be made across an unsecured network. Example protocols are PPTP - L2TP - and IPSec.






19. Standard that addresses wireless MAN technologies.






20. 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.






21. 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






22. 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.






23. Works like a private line for a customer with an agreed upon bandwidth. Path is programmed into the WAN devices.






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






25. 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.






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






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






28. 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.






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






30. Type of firewall that can be compromised if the OS does not have packet forwarding or routing turned off.






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






32. Protocol that is used by remote users to authenticate over PPP lines. Sends passwords over clear text. Vulnerable to MITM attacks.






33. VPN protocol that can run in other networks (frame relay - X.25 - ATM). Does not provide encryption - lacks the security to be called a true "VPN" solution.






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






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






36. 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.






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






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






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






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






41. 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.






42. Type of firewall that looks at header information to make decisions on whether a packet is deemed acceptable. This type does not look as deep within the packet as an application level proxy - runs at the session layer.






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






44. Dynamically builds ACL's to allow internal systems to communicate with external systems. Once the connection is finished - the ACL is removed from the list. 4th generation firewall.






45. Faster because processing is done in the kernel. One network stack is created for each packet. 5th generation firewall - runs at the application layer.






46. Type of ethernet implementation that uses a thicker coaxial cable - which allows a longer cable length to be used.






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






48. Wireless standard that will improve security of wireless communication






49. 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






50. Spam over IM
