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






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






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






4. 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.






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






6. 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).






7. Standard that addresses wireless MAN technologies.






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






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






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






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






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






13. 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.






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






15. 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.






16. 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.






17. 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.






18. 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.






19. Wireless communication that distributes individual signals across the allocated frequencies.






20. 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.






21. A WAN protocol that works at the data link layer and performs packet switching. Economical choice because the fee is based on bandwidth usage rather than a dedicated pipeline.






22. Type of authentication protocol that provides a framework to enable may types of authentication techniques to be used during PPP connections. It extends the possibilities to one-time passwords - token cards - biometrics - Kerberos - and digital certi






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






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






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






26. 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.






27. 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.






28. 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.






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






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






31. Spam over IM






32. 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.






33. 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.






34. 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






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






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






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






38. 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.






39. 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






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






41. 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.






42. Firewall that does not require a proxy for each service; does not provide detailed access control; but does provide for a wider range of protocols.






43. 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.






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






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






46. Communication devices that determine synchronization scheme before data transmission.






47. 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.






48. 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.






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






50. 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.
