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 network layout that separates and group computers logically.






2. 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






3. 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.






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






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






6. 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.






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






8. OSI layer 2 Sub-layers. The first provides a standard interface for the network protocol being used. The second provides a standard interface for the physical layer protocol being used.






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






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






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






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






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






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






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






16. 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.






17. 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.






18. 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.






19. 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).






20. 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.






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






22. 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






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






24. Type of network device that divides networks into more controllable segments to ensure more efficient use of bandwidth. Works at the data link layer and understands MAC addresses - not IP addresses.






25. 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.






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






27. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






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






29. 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






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






31. Communication devices that are not synchronized - meaning all devices can send data at will - send a sequence of bits framed with a start and stop bit.






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






34. 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.






35. 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.






36. 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.






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






38. 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.






39. 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.






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






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






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






43. 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.






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






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






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






47. Strengths of a type of firewall: Better security than packet filtering. Looks at all info in the packet - up to the application layer. Breaks the connection between trusted and untrusted systems. Weaknesses include limited number of applications supp






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. 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.






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