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






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






3. 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.






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






5. 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.






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






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






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






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






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






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






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






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






14. 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.






15. 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.






16. VPN protocol that works at the network layer - handles multiple connections - provides secure authentication and encryption. Tunnel mode option (payload and header encrypted) - or transport mode (only payload is encrypted).






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






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






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






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






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






22. Spam over IM






23. OSI layer that provides end to end transmission between computer systems. Protocols that use this layer are TCP (Transmission Control Protocol) - UDP (User Datagram Protocol) - SPX (Sequenced Packet Exchange) - and SSL.






24. 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






25. 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






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






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






28. 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.






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






30. Proprietary protocol that enables secondary devices to communicate with primary stations or mainframes in an IBM architecture. Developed in the mid-70's for use in a systems network architecture (SNA) environment. First synchronous - link layer - bit






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






32. 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.






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






34. Communication devices that determine synchronization scheme before data transmission.






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






36. 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.






37. 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






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






40. 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.






41. 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.






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






43. 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.






44. 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.






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






46. 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.






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






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






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






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