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






2. 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.






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






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






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






6. 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






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






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






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






10. OSI layer that sets up - maintains - and breaks down the dialog (session) between two applications. Controls dialog organization and synchronization. Protocols that work at this layer are NFS (Network File System) - SQL - NetBIOS - RPC.






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






12. 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.






13. 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






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






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






16. 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.






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






18. Protocol that transfers data in fixed cells (53 bytes) - is a WAN technology - and transmits data at very high rates. Supports voice - data - and video applications.






19. 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.






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






21. Type of firewall that looks at header information to make decisions on whether a packet is deemed acceptable. This type does not look as deep within the packet as an application level proxy - runs at the session layer.






22. 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






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






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






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






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






27. Standard that addresses wireless MAN technologies.






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






29. 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.






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






31. 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.






32. 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.






33. 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).






34. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






36. 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.






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






38. 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.






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. 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.






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






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






43. 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.






44. 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.






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






46. 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.






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






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






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






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