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






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






3. 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.






4. 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.






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






6. 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.






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






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






9. 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.






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. 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.






12. Encapsulation protocol for telecommunication connections. Replaced SLIP and is ideal for connection different types of devices over serial lines.






13. 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).






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






15. Spam over IM






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






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






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






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






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






21. 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.






22. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






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






26. More complexity and drastically increases the difficultly of access control. Many different devices - services - and users make it difficult to know which entities to trust and to what degree.






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






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






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






30. 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






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






32. 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.






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






34. 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.






35. 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.






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






37. 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-






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






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






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






41. 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.






42. Wireless standard that will improve security of wireless communication






43. Type of network layout that separates and group computers logically.






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






45. Network where a dedicated virtual link is not set up - and packets can use many different dynamic paths to get to the same destination. This causes variable delays. Examples are frame relay and X.25






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






47. Type of network that allows large IP ranges to be divided into smaller - logical - and easier to maintain network segments.






48. 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.






49. 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.






50. 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.
