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. 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.






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






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






4. 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






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






6. 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.






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






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






9. 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).






10. 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.






11. 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.






12. 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.






13. Developed to replace the aging telephone and analog systems. BRI rate that uses two B channels (send/receive) - and one D channel (control information) - and PRI rate that uses up to 23 B channels. Supports voice - data - and video. Provides up to 1.






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






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






16. Standard that addresses wireless MAN technologies.






17. 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.






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






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






20. Type of cable that carries data as light waves - expensive - can transmit data at high speeds - difficult to tap into - and is resistant to EMI. Most secure cabling option - but vulnerable to dispersion.






21. 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.






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






23. 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






24. 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.






25. 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.






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






27. 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






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






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






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






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






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






33. Both directions - only one application can send information at a time






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






35. 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.






36. 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).






37. 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.






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






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






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






41. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






43. 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.






44. A packet switching technology that is used by telecommunication services for data-only traffic. It is a subscriber based service that operates within the network and data link layers.






45. 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.






46. 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.






47. 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.






48. 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.






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






50. 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.
