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. A technique that allows multiple layers of nesting. Example - IPSec tunnel can originate or terminate at a different IPSec site along the way.






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






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






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






5. 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.






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






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






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






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






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






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






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






13. 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-






14. Spam over IM






15. 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






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






17. 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.






18. 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






19. 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.






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






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






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






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






24. 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).






25. 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.






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






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






28. 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.






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






30. This is a standard for fiber-optic cabling and uses self-healing network rings. This standard describes the interfaces that can be used over fiber lines and the signaling that can be employed. Works at the physical layer of the OSI model.






31. 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).






32. 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.






33. 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.






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






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






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






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






38. 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






39. Type of switch that uses tags that are assigned to each destination network. The network compares the tag with its tag information base - appends the appropriate tag - and forwards to the next switch. This increases the transmission speed - allows la






40. 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






41. 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.






42. 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.






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






44. Created because it was clear that available IP addresses were running out. Provides flexibility to increase or decrease the IP classes sizes as necessary.






45. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






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






48. 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.






49. 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.






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