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






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






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






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






5. More complexity and drastically increases the difficultly of access control. Many different devices - services - and users make it difficult to know which entities to trust and to what degree.






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






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






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






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






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






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






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. 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.






14. Type of wireless authentication where the device does not need to provide a key for authentication. Usually - only the SSID is required and plaintext transmission occurs.






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. 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






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






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






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






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






21. 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.






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






23. 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.






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






25. 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.






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






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






28. 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






29. 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.






30. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






31. 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.






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






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






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






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






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






37. 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.






38. 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.






39. 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.






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






41. 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.






42. This dedicated connection provides up to 1.544 Mbps bandwidth over 1 T1 and 24 time divided channels.






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






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






45. 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.






46. Protocol that is best-effort - connectionless - and does not sent acknowledgements.






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






48. 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






49. 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.






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