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. 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.






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






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






4. 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.






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






6. 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.






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






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






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






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






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






12. 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.






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






14. 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.






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






16. 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.






17. 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






18. Communication devices that are not synchronized - meaning all devices can send data at will - send a sequence of bits framed with a start and stop bit.






19. Wireless standard that will improve security of wireless communication






20. 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.






21. 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.






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






23. 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.






24. 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.






25. OSI layer that provides physical connections for transmission and performs the electrical encoding of data. This layer transforms bits to electrical signals. Protocols at this level HSSI (High Speed Serial Interface) - X.21 - EIA/TIA 232 and 449.






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






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






28. Type of cabling problem where data is corrupted going from end to end due to surrounding devices.






29. 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.






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






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






32. 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.






33. Both directions - only one application can send information at a time






34. Network where a virtual connection that acts like a dedicated link between two systems is set up. Traffic travels in a predictable and constant manner. Example - telephone.






35. 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.






36. 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






37. 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.






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






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






40. 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.






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






42. 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.






43. 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.






44. Standard that addresses wireless MAN technologies.






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






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






47. Protocol where all computers compete for the shard network cable - listen to learn when they can transmit data - susceptible to data collisions. Used by Ethernet.






48. 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.






49. Type of wireless authentication where a shared WEP key is used to encrypt a nonce for authentication.






50. 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.
