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. Premium service offered by service providers in frame relay networks that guarantees a company a specified amount of bandwidth.






2. 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






3. Spam over IM






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






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






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






7. The well known values range from 0-1023. FTP runs on 20 and 21 - SMTP runs on 25 - TFTP runs on 69 - DNS runs on 53 - HTTP runs on 80 - HTTPS runs on 443 - SNMP runs on 161.






8. 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.






9. Transmits high speed bandwidth over phone lines. Provides data rates up to 52 Mpbs using line of 1000 feet or less. Must be within 2.5 miles of a central office.






10. 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.






11. 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






12. Wireless standard that will improve security of wireless communication






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






14. 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.






15. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






16. 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






17. 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.






18. 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.






19. 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.






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






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






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






23. 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.






24. Both directions - both applications can send information at a time. Session Layer Communication Modes






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






26. 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.






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






28. 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.






29. Problems: Central device is a single point of failure.






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






31. 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.






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






33. 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.






34. 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.






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






36. 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






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






38. 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.






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






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






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






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






43. 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






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






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 backbone network that joins together LAN to other LANs and WANs to LANs - etc. Typically known as Synchronous Optical Networks (SONETS) or FDDI rings.






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






48. 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).






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






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