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. VPN protocol that works at the network layer - handles multiple connections - provides secure authentication and encryption. Tunnel mode option (payload and header encrypted) - or transport mode (only payload is encrypted).






2. 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






3. Strengths of a type of firewall: application independence - high performance - and scalability. Weaknesses include low security - no protection above the network layer.






4. Altering an ARP table so an IP address is mapped to a different MAC address. Results in traffic being routed to an attacker's computer.






5. 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






6. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






8. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






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






11. Spam over IM






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






13. 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.






14. 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.






15. 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.






16. 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.






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






18. 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.






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






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






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






23. 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).






24. 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






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






26. 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.






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






28. 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.






29. Application layer request/response protocol widely used for VoIP communication sessions. Transported by UDP - makes use of TCP - and is vulnerable to sniffing attacks.






30. 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.






31. 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.






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






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






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






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






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






37. 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.






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






39. 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.






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






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






42. This dedicated connection provides up to 1.544 Mbps bandwidth over 1 T1 and 24 time divided channels.






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






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






45. 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.






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






47. 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.






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






49. 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






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