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. 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.






2. 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






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






4. Used when companies do not want systems to know internal hosts IP addresses. Enables companies to use private - nonroutable IP addresses.






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






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






7. 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






8. Malware attack that sends commands inside of an ICMP packet.






9. 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.






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






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






12. 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.






13. Type of firewall that Inspects incoming/outgoing messages for malicious information. If approved - transfers an isolated copy from one network to another. 2nd generation firewall.






14. The original technique to digitized voice with 8 bits of sampling 8 -000 times per second - which yields 64 Kbps for one voice channel.






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






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






17. 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.






18. Type of firewall that is also know as a screening router and is accomplished by ACL's (Lines of text called rules). Traffic can be filtered by address - ports - and protocol types. 1st generation firewall - runs at the network layer.






19. 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






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






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






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






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






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. 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. SMTP server that is configured for sending email from any source to and destination.






27. 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.






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






29. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






32. This dedicated connection provides 45Mbps of bandwidth over 28 T1 lines and 672 time divided channels.






33. Protocol that increases address size from 32 bits to 128 bits






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






35. Wireless standard that will improve security of wireless communication






36. These are used to connect multiple switches for traffic of the same classification. Example - two voice switches at a local phone company's central office.






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






38. 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.






39. 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).






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






41. 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.






42. 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.






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






44. 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.






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






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






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






48. 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.






49. 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.






50. Type of cable where STP and UTP (shielded and unshielded) cables are the most popular - cheapest - and easiest to work with. However - easiest to tap into - have cross talk issues - and are vulnerable to electromagnetic interference (EMI).
