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






2. 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.






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






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






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






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






7. 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.






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






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






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






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






12. 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.






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






14. 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.






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






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






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






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






19. Standard that addresses wireless MAN technologies.






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






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






23. 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






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






25. 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.






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






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






28. Security wireless standard that rotates encryption keys - stronger IV values - MAC codes for packet integrity. Works in combination with WEP.






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






30. 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.






31. Type of ethernet implementation that uses a thicker coaxial cable - which allows a longer cable length to be used.






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






33. 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






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






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






36. 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.






37. Protocol that is reliable and connection-oriented - which means it ensures delivery through acknowledgements - sequencing - detection and correction.






38. 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.






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






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






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






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






43. 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).






44. 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.






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






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






47. 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.






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






49. 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.






50. 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
