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






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






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






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






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. 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.






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






8. 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.






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






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






11. 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.






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






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






14. 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.






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






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






17. 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.






18. 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).






19. 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.






20. Standard that addresses wireless MAN technologies.






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






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






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






24. 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.






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






26. 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.






27. 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.






28. OSI layer that sets up - maintains - and breaks down the dialog (session) between two applications. Controls dialog organization and synchronization. Protocols that work at this layer are NFS (Network File System) - SQL - NetBIOS - RPC.






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






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






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






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






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






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






35. Type of ethernet implementation that uses a standard coaxial cable with a maximum cable length of 185 meters. 10Mbps.






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






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






38. 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.






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






40. Type of topology that Uses linear single cable for all computers attached. All traffic travels full cable and can be viewed by all other computers.






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






42. 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






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






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






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






46. 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.






47. Communication devices that determine synchronization scheme before data transmission.






48. 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.






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






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