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






2. 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.






3. 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.






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






5. 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.






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






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






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






9. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






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






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






12. Device used within companies to provide multiple services to users throughout a building or facility. Example - dialing 9 to place outbound phone calls. Security concerns: default configurations and passwords - maintenance modems disabled - unused co






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






14. 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.






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






16. 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.






17. 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).






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






19. 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






20. Protocol where all computers compete for the shard network cable - listen to learn when they can transmit data - susceptible to data collisions. Used by Ethernet.






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






22. Used when a LAN device needs to communicate with WAN devices over telephone lines. Ensures the necessary electrical signaling and format are used. Interfaces with Data Terminal Equipment (DTE) and Data Circuit-Terminal Equipment (DCE).






23. 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.






24. 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






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






26. 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.






27. 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.






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






29. 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.






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






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






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






33. 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.






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






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






37. Type of switch that uses tags that are assigned to each destination network. The network compares the tag with its tag information base - appends the appropriate tag - and forwards to the next switch. This increases the transmission speed - allows la






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






39. 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.






40. 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.






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






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






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






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






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






46. 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.






47. 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






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






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






50. Standard that addresses wireless MAN technologies.
