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






2. VPN protocol that works at the data link layer - can only run in IP networks - and provides encryption and encapsulation. This is Microsoft's VPN solution.






3. 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.






4. 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.






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






6. 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).






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






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. 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).






11. 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.






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






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






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






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






16. Created because it was clear that available IP addresses were running out. Provides flexibility to increase or decrease the IP classes sizes as necessary.






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






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






19. 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.






20. 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.






21. 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.






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






23. 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






24. 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.






25. 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.






26. 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.






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






28. 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.






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






30. Type of firewall that is also know as a screening router and is accomplished by ACL's (Lines of text called rules). Traffic can be filtered by address - ports - and protocol types. 1st generation firewall - runs at the network layer.






31. 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.






32. 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






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






34. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






37. This is a standard for fiber-optic cabling and uses self-healing network rings. This standard describes the interfaces that can be used over fiber lines and the signaling that can be employed. Works at the physical layer of the OSI model.






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






39. 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.






40. 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






41. Standard that addresses wireless MAN technologies.






42. 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.






43. Type of host that is locked down - hardened - system. Systems installed in the DMZ (firewalls - servers) should be installed on this type of host.






44. 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.






45. Type of network that allows large IP ranges to be divided into smaller - logical - and easier to maintain network segments.






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






47. 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






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






49. 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.






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