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. An older protocol that was used by ISP's to encapsulate data to be sent over dial up connections






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






3. 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.






4. Type of network device that links 2 or more network segments - where each segment can function as an independent network. Works at the network layer - works with IP addresses - and has more network knowledge than the other hardware.






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






6. 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.






7. 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






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






9. 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.






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






11. 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.






12. 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.






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






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






15. 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.






16. Type of network layout that separates and group computers logically.






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






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






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






20. 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.






21. 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.






22. 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.






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






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






25. 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).






26. 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.






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






28. 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.






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






30. 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.






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






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. 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.






34. 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.






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






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






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






38. 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.






39. Most commonly used LAN implementation today. Considered a "chatty" protocol because it allows all systems to hear each other's broadcasts. Has many collisions because all systems share the same medium. Can operate at 10 to 1000 Mbps.






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






41. 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.






42. Type of network device that is the simplest type of connectivity because it only repeats and amplifies electric signals between cable segments. Works at the physical layer.






43. 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.






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






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






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






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






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






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






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