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






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






3. 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).






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






5. 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.






6. 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.






7. 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.






8. 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






9. New variant to traditional email spam on VoIP networks.






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






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






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






13. 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






14. 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.






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






16. Protocol that is best-effort - connectionless - and does not sent acknowledgements.






17. OSI layer that prepares data for the network medium by framing it into LAN/WAN frames. Defines how the physical layer transmits the network packets. Protocols at this layer ARP (Address Resolution Protocol) - RARP (Reverse Address Resolution Protocol






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






19. 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.






20. 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.






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






22. 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.






23. Protocol based on the SDLC protocol - except it is an open protocol - supports full-duplex connections - and provides a higher throughput. It also provides polling - which enables secondary units to communicate with primary units.






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






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






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






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






28. These are used to connect multiple switches for traffic of the same classification. Example - two voice switches at a local phone company's central office.






29. 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.






30. 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.






31. 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.






32. 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.






33. The original technique to digitized voice with 8 bits of sampling 8 -000 times per second - which yields 64 Kbps for one voice channel.






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






35. 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






36. 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.






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






38. Type of wireless security standard that uses AES in CBC mode.






39. 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.






40. 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






41. 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.






42. 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.






43. 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






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






45. 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.






46. 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.






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






48. Type of wireless authentication where a shared WEP key is used to encrypt a nonce for authentication.






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






50. Spam over IM
