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






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






3. 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.






4. VPN protocol that can run in other networks (frame relay - X.25 - ATM). Does not provide encryption - lacks the security to be called a true "VPN" solution.






5. Security wireless standard that enables data transfers to be encrypted. Static encryption keys among clients - short 40 bit keys - RC4 encryption - ineffective use of 24 bit IV's - and no packet integrity.






6. 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.






7. 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.






8. Spam over IM






9. 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






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






11. 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.






12. 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.






13. 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






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






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






16. 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.






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






18. 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.






19. Proprietary protocol that enables secondary devices to communicate with primary stations or mainframes in an IBM architecture. Developed in the mid-70's for use in a systems network architecture (SNA) environment. First synchronous - link layer - bit






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






21. 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.






22. 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.






23. 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.






24. 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.






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






26. 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.






27. 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.






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






29. 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.






30. 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






31. 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).






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






33. 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






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






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






36. 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.






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






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






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






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






41. Standard that addresses wireless MAN technologies.






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






43. 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.






44. 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.






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






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






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






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






49. 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.






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