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






2. 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).






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






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






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






6. 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.






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






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






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






10. 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-






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






12. Type of LAN and MAN technology - usually used for backbones - that uses token-passing technology and has redundant rings in case the primary ring goes down.






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






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






15. 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.






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






17. Device used within companies to provide multiple services to users throughout a building or facility. Example - dialing 9 to place outbound phone calls. Security concerns: default configurations and passwords - maintenance modems disabled - unused co






18. 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.






19. 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.






20. 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.






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






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






23. 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.






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






25. Both directions - both applications can send information at a time. Session Layer Communication Modes






26. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






29. Malware attack that sends commands inside of an ICMP packet.






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






31. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






32. 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






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






34. 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).






35. 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.






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






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






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






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






40. 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.






41. Protocol that addresses vulnerabilities found in PAP. Uses challenge/response mechanism to authenticate the user instead of sending password.






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






43. OSI layer that has services and protocols required by the user's applications for network functionality. Example protocols include HTTP - SMTP - FTP - Telnet.






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






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






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






47. Type of cable that carries data as light waves - expensive - can transmit data at high speeds - difficult to tap into - and is resistant to EMI. Most secure cabling option - but vulnerable to dispersion.






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






49. 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.






50. 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.
