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






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






3. 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






4. 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.






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






6. A WAN protocol that works at the data link layer and performs packet switching. Economical choice because the fee is based on bandwidth usage rather than a dedicated pipeline.






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






8. Strengths of a type of firewall: application independence - high performance - and scalability. Weaknesses include low security - no protection above the network layer.






9. 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.






10. 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.






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






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






13. 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.






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






15. 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.






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






17. 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






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






19. 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.






20. 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.






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. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






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






24. 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.






25. 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).






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






27. 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.






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






29. 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.






30. Used when a LAN device needs to communicate with WAN devices over telephone lines. Ensures the necessary electrical signaling and format are used. Interfaces with Data Terminal Equipment (DTE) and Data Circuit-Terminal Equipment (DCE).






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






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






33. Spam over IM






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






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






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






37. 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.






38. Strengths of a type of Stateful Firewall: High security - better performance than an application firewall. Weaknesses include more complex - ___________ - if rebooted all information is lost.






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






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






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






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






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






44. 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.






45. 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.






46. 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.






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






48. 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.






49. 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.






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