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. 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.






2. Standard that addresses wireless MAN technologies.






3. Wireless standard that will improve security of wireless communication






4. 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.






5. 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.






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






7. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






8. 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.






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






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






11. Protocol based on the SDLC protocol - except it is an open protocol - supports full-duplex connections - and provides a higher throughput. It also provides polling - which enables secondary units to communicate with primary units.






12. 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






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






14. Spam over IM






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






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






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






18. Protocol that works at the network layer and informs hosts - routers - and devices of network or computer problems. It is the major component of the ping utility.






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






20. Type of network device that links 2 or more network segments - where each segment can function as an independent network. Works at the network layer - works with IP addresses - and has more network knowledge than the other hardware.






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






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






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






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






25. 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.






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






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






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






29. 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.






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






31. The well known values range from 0-1023. FTP runs on 20 and 21 - SMTP runs on 25 - TFTP runs on 69 - DNS runs on 53 - HTTP runs on 80 - HTTPS runs on 443 - SNMP runs on 161.






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






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






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






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






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






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






38. 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.






39. Type of network device that divides networks into more controllable segments to ensure more efficient use of bandwidth. Works at the data link layer and understands MAC addresses - not IP addresses.






40. 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.






41. 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).






42. 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.






43. OSI layer that provides end to end transmission between computer systems. Protocols that use this layer are TCP (Transmission Control Protocol) - UDP (User Datagram Protocol) - SPX (Sequenced Packet Exchange) - and SSL.






44. 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






45. 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






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






47. 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.






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






49. Protocol that translates IP address into a MAC address (physical Ethernet address)






50. 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.
