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






2. 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.






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






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






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






6. Wireless standard that will improve security of wireless communication






7. 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.






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






9. 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.






10. 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






11. 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.






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






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






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






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






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






17. 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.






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






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






20. 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-






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






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






23. 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.






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






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






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






27. 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.






28. 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).






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






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






31. Developed to replace the aging telephone and analog systems. BRI rate that uses two B channels (send/receive) - and one D channel (control information) - and PRI rate that uses up to 23 B channels. Supports voice - data - and video. Provides up to 1.






32. 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.






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






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






35. The well known values range from 0-1023. FTP runs on 20 and 21 - SMTP runs on 25 - TFTP runs on 69 - DNS runs on 53 - HTTP runs on 80 - HTTPS runs on 443 - SNMP runs on 161.






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






37. 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).






38. 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.






39. 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.






40. 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






41. 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.






42. 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






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






44. 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.






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






47. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






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