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






2. 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.






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






4. 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.






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






6. 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.






7. 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.






8. 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






9. 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.






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






11. 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.






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






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






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






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






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






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






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






19. 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.






20. 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.






21. 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.






22. 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.






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






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. 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






26. 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.






27. 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






28. 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.






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






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






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






32. 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.






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






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






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






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






37. Type of network layout that is a large geographical region connecting more that one LAN.






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






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






40. 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.






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






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






43. 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






44. Type of network that allows large IP ranges to be divided into smaller - logical - and easier to maintain network segments.






45. 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.






46. 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.






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






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






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






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