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






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






3. Standard that addresses wireless MAN technologies.






4. 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






5. 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






6. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






7. Protocol stack used instead of TCP/IP on wireless devices. The "gap" in this protocol involves translating its secure traffic to SSL or TLS - which is typically done by a 3rd party.






8. 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.






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






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






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






12. 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.






13. 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






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






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






17. This network technology determines which system will send data based on which one has the token.






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






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






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






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






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






23. 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.






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






25. 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.






26. 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.






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






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






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






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






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






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






33. 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.






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






35. 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).






36. 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.






37. 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.






38. 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.






39. 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.






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






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






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






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






44. 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






45. Type of cable where STP and UTP (shielded and unshielded) cables are the most popular - cheapest - and easiest to work with. However - easiest to tap into - have cross talk issues - and are vulnerable to electromagnetic interference (EMI).






46. Provides high-speed access - up to 50 Mbps - to the Internet through existing cable coaxial and fiber lines. Major security concern is the fact that neighbors use the same coaxial network and can monitor each others traffic.






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






48. 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.






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






50. 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.
