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






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






3. Type of cabling problem where loss of signal strength occurs as it travels due to cable exceeding its recommended length.






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






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






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






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






8. 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.






9. 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.






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






11. 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.






12. 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.






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






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






15. 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.






16. Wireless communication that splits total amount of bandwidth into smaller sub-channels. Send and receiver work in one of the channels for a period of time - and then move into a different channel. It uses a portion of the bandwidth - throughput of 1-






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






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






19. 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.






20. 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.






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






23. 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).






24. 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






25. 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.






26. 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.






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






28. 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.






29. 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.






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






31. 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.






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






33. 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.






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






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






36. Used when a LAN device needs to communicate with WAN devices over telephone lines. Ensures the necessary electrical signaling and format are used. Interfaces with Data Terminal Equipment (DTE) and Data Circuit-Terminal Equipment (DCE).






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






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






39. Protocol that is best-effort - connectionless - and does not sent acknowledgements.






40. 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.






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






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






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






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






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






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






47. 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






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






49. More complexity and drastically increases the difficultly of access control. Many different devices - services - and users make it difficult to know which entities to trust and to what degree.






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