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






2. 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.






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






4. Type of firewall that Inspects incoming/outgoing messages for malicious information. If approved - transfers an isolated copy from one network to another. 2nd generation firewall.






5. 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.






6. OSI layer 2 Sub-layers. The first provides a standard interface for the network protocol being used. The second provides a standard interface for the physical layer protocol being used.






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






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






9. 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.






10. 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.






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






12. 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.






13. 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






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






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






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






17. Combines voice and data over the same IP network media and protocol. Reduces the cost of implementing and maintaining two different networks.






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






19. Spam over IM






20. 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.






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






22. Wireless communication that distributes individual signals across the allocated frequencies.






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






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






25. Type of network device that is the simplest type of connectivity because it only repeats and amplifies electric signals between cable segments. Works at the physical layer.






26. 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.






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






28. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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. 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.






31. 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.






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






33. 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).






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






35. 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.






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






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






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






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






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






41. Network where a virtual connection that acts like a dedicated link between two systems is set up. Traffic travels in a predictable and constant manner. Example - telephone.






42. Problems: Requires more expense in cabling and extra effort to track down cable faults.






43. 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.






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






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






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






47. Protocol that is reliable and connection-oriented - which means it ensures delivery through acknowledgements - sequencing - detection and correction.






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






50. 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.
