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. 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.






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






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






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






5. Type of cabling problem where data is corrupted going from end to end due to surrounding devices.






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






7. 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).






8. Type of topology that where all computers are connected to a central device (AKA hub) - which provides more resilience for the network.






9. 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.






10. 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.






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






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






13. 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.






14. 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).






15. Protocol that transfers data in fixed cells (53 bytes) - is a WAN technology - and transmits data at very high rates. Supports voice - data - and video applications.






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






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






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






19. 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.






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






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






22. 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.






23. 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.






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






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






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






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






28. 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.






29. 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.






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






31. 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.






32. 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.






33. 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.






34. A simplified version of X.25 - without the error checking that was done on the network. It handles error checking at the end node - which helps improve speed dramatically.






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






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






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






38. An older protocol that was used by ISP's to encapsulate data to be sent over dial up connections






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






40. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






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






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






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






44. Application layer request/response protocol widely used for VoIP communication sessions. Transported by UDP - makes use of TCP - and is vulnerable to sniffing attacks.






45. 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






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






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






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






49. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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