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. 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.






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






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






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






5. 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.






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






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






8. VPN protocol that works at the data link layer - can only run in IP networks - and provides encryption and encapsulation. This is Microsoft's VPN solution.






9. 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.






10. Type of topology that uses a bus that does not have a one linear cable - but instead uses branches of cables. Commonly used in Ethernet.






11. 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.






12. 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.






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






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






15. 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.






16. 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).






17. Spam over IM






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






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






20. Protocol that resolves host names into IP addresses and has distributed databases all over the Internet to provide name resolution.






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






22. 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






23. 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.






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






25. Wireless LAN standard that operates in a 2.4Ghz range - 11Mbps - DSSS






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






27. 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.






28. 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.






29. Problems: Central device is a single point of failure.






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






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






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






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






34. Type of firewall that Inspects incoming/outgoing messages for malicious information. If approved - transfers an isolated copy from one network to another. 2nd generation firewall.






35. Standard that addresses wireless MAN technologies.






36. OSI layer that prepares data for the network medium by framing it into LAN/WAN frames. Defines how the physical layer transmits the network packets. Protocols at this layer ARP (Address Resolution Protocol) - RARP (Reverse Address Resolution Protocol






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






38. 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).






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






40. Protocol stack used instead of TCP/IP on wireless devices. The "gap" in this protocol involves translating its secure traffic to SSL or TLS - which is typically done by a 3rd party.






41. Protocol that is reliable and connection-oriented - which means it ensures delivery through acknowledgements - sequencing - detection and correction.






42. 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.






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






44. 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






45. Most expensive type of WAN connection because the fee is based on distance between the two points rather than the amount of bandwidth used. Examples - T1 and T3.






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






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






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






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






50. Protocol that is best-effort - connectionless - and does not sent acknowledgements.
