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






2. A WAN protocol that works at the data link layer and performs packet switching. Economical choice because the fee is based on bandwidth usage rather than a dedicated pipeline.






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






4. 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.






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






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






7. 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.






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






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






10. 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.






11. 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.






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






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






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






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






16. 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






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






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






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






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






21. 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.






22. Type of ethernet implementation that uses a standard coaxial cable with a maximum cable length of 185 meters. 10Mbps.






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






24. 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.






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






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






27. 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.






28. 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.






29. 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.






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






31. Spam over IM






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






33. 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






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






35. Type of network device that links 2 or more network segments - where each segment can function as an independent network. Works at the network layer - works with IP addresses - and has more network knowledge than the other hardware.






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






37. Standard that addresses wireless MAN technologies.






38. 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.






39. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






40. 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).






41. 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






42. In the OSI layer 5 - these are the types of what?






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






44. 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.






45. 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.






46. 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.






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






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






49. 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.






50. 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).
