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. Wireless standard that will improve security of wireless communication






3. Spam over IM






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






5. 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.






6. 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






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






8. 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.






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






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






11. VPN protocol that can run in other networks (frame relay - X.25 - ATM). Does not provide encryption - lacks the security to be called a true "VPN" solution.






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






13. 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.






14. 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-






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






16. 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).






17. 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.






18. Protocol based on the SDLC protocol - except it is an open protocol - supports full-duplex connections - and provides a higher throughput. It also provides polling - which enables secondary units to communicate with primary units.






19. 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.






20. 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.






21. Older LAN implementation that uses a token-passing technology. Can send a beacon frame to indicate that a certain computer is failing and its neighbors should reconfigure and work around the detected fault.






22. 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.






23. Protocol that addresses vulnerabilities found in PAP. Uses challenge/response mechanism to authenticate the user instead of sending password.






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






25. Type of cable that is more expensive than UTP and STP - more resistant to EMI - can carry baseband and board band technologies.






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






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






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






29. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






30. 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.






31. 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.






32. OSI layer that has services and protocols required by the user's applications for network functionality. Example protocols include HTTP - SMTP - FTP - Telnet.






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






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






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






36. This network technology determines which system will send data based on which one has the token.






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






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






39. Security wireless standard that enables data transfers to be encrypted. Static encryption keys among clients - short 40 bit keys - RC4 encryption - ineffective use of 24 bit IV's - and no packet integrity.






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






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






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






43. 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.






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






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






46. 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.






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






49. 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).






50. 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.
