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. 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.






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






3. In the OSI layer 5 - these are the types of what?






4. 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






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






6. 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






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






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






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






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






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






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






13. Standard that addresses wireless MAN technologies.






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






15. 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.






16. 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.






17. Type of network device that divides networks into more controllable segments to ensure more efficient use of bandwidth. Works at the data link layer and understands MAC addresses - not IP addresses.






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






19. 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.






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






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






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






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






24. Type of backbone network that joins together LAN to other LANs and WANs to LANs - etc. Typically known as Synchronous Optical Networks (SONETS) or FDDI rings.






25. 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






26. 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






27. 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.






28. 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.






29. Both directions - only one application can send information at a time






30. Spam over IM






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






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






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






34. Wireless standard that will improve security of wireless communication






35. 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.






36. OSI layer that provides end to end transmission between computer systems. Protocols that use this layer are TCP (Transmission Control Protocol) - UDP (User Datagram Protocol) - SPX (Sequenced Packet Exchange) - and SSL.






37. 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.






38. 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.






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






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






41. 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.






42. 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.






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






44. 4: Application - 3: Host-to-Host - 2: Internet - 1: Network Access - 3 -1 -1 -2 will map to the OSI model.






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






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






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






49. 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.






50. 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.
