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.

2. TCP and UDP Port 162






3. Access-list <number> <deny | permit> source source-wildcard log






4. War dialing






5. Tunnel Mode Protocol provides integrity - authentication - and non-repudiation and operates directly on top of IP






6. Command used to disable the ICMP message Address Mask Reply






7. Router threat that refers to willful attempts to cause such disruptions by overwhelming the targeted system with improperly formatted traffic






8. Attack that involves sending a large amount of ICMP Echo packets to a subnet's broadcast address with a spoofed source IP address from that subnet






9. Transport and Tunnel






10. Datagram protocol used by some hosts to load their operating system over the network via a central repository of IOS software






11. Attack that involves sending a large amount of UDP Echo packets to a subnet's broadcast address with a spoofed source IP address from that subnet






12. Refers to addresses used on the organization's private network






13. None - uses attached application protocol's port






14. 0x32 - or 50






15. An extension of static mapping which allows for one global address to be mapped to multiple inside addresses; can be used for websites with multiple back end servers






16. Major Version - Minor Version - Release - Interim Build - Release Train Identifier






17. Release Number






18. Router to Router Denial of Service






19. Layer 5






20. Commands to disable Finger Server






21. Provides a checksum - ensuring traffic has not been modified along it's path






22. Lists interfaces - routing table - ARP table - physical and network addresses - time last booted






23. UDP Port 1701






24. Can obtain CIDR and router ID






25. Startup-config can be deleted - copied - changed






26. Cisco default tunneling protocol that uses multicast addressing without encryption and is designed to encapsulate a wide variety of network layer packets inside IP tunneling packets






27. Uses only host keys to authenticate systems






28. Also known as Configuration Auto-Loading - allows routers to load their startup configuration from the network






29. Rewrites the and/or destination IP address of IP packets as they pass through a router or firewall from private to public addresses

36. 1300-1999






37. Routing mode depended on by uRPF in order to function






38. Allows for a one-to-one translation of local to global addresses; used by web servers and mail servers so that users can connect to them via their global address

40. 0x33 or 51






41. Four TCP/UDP Small Server commands recommended to disable






42. Router threat that occurs when an attacker manipulates IP packets to falsify IP addresses - causing network disruptions as the router attempts to process the packet






43. Two - one Inbound or Evaluated and one Outbound or Reflected






44. Two FIN bits or one RST bit






45. Software that passively monitors the connection requests flowing through the router; if a connection fails - the software sends a Reset to the server to clear up its state
