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 twisted-pair copper wiring and transmits at 100Mbps.






2. Dynamically builds ACL's to allow internal systems to communicate with external systems. Once the connection is finished - the ACL is removed from the list. 4th generation firewall.






3. 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.






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






5. Standard that addresses wireless MAN technologies.






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






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






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






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






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






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






13. 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.






14. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






16. 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.






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






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






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






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






21. 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.






22. Protocol that is used by remote users to authenticate over PPP lines. Sends passwords over clear text. Vulnerable to MITM attacks.






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






24. Type of topology that uses a bus that does not have a one linear cable - but instead uses branches of cables. Commonly used in Ethernet.






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






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






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






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






29. 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.






30. 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






31. 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-






32. 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.






33. Network cabling that is placed in these types of areas must meet a specific fire rating. These cables typically have a jacked cover made of fluoropolymers.






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






35. Type of wireless security standard that uses AES in CBC mode.






36. 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.






37. 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.






38. Type of network device that allows different network segments and/or systems to communicate. When communication takes place - a dedicated connection is set up - so collision and broadcast data is not available to other devices. Combined repeater (hub






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






40. 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.






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






42. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






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






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






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






47. 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.






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






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






50. 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.
