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. Faster because processing is done in the kernel. One network stack is created for each packet. 5th generation firewall - runs at the application layer.






2. 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.






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






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






5. SMTP server that is configured for sending email from any source to and destination.






6. 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.






7. OSI layer that provides physical connections for transmission and performs the electrical encoding of data. This layer transforms bits to electrical signals. Protocols at this level HSSI (High Speed Serial Interface) - X.21 - EIA/TIA 232 and 449.






8. Server that can be configured to hang up and call back remote users - but this can be compromise by enabling call forwarding.






9. 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.






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






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






13. This network technology determines which system will send data based on which one has the token.






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






15. 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.






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






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






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






19. Type of wireless authentication where the device does not need to provide a key for authentication. Usually - only the SSID is required and plaintext transmission occurs.






20. 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.






21. 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.






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






23. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






25. 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






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






27. 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.






28. 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






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






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






31. 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.






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






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






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






35. 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.






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






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. 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.






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






40. Wireless communication that splits total amount of bandwidth into smaller sub-channels. Send and receiver work in one of the channels for a period of time - and then move into a different channel. It uses a portion of the bandwidth - throughput of 1-






41. 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.






42. 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).






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






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






45. 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.






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






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






48. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






49. 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.






50. 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.
