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. Can stop spoofed IP addresses






2. Interim Build Number






3. Mode where the entire packet is encrypted and/or authenticated - requiring a new IP packet to be encapsulated






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






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






6. Public IP address after translation






7. Router to Router Denial of Service






8. Privilege level that restricts users to five commands (enable - disable - exit - help quit)






9. Top of the hierarchy - responsible for transporting large amounts of traffic both reliably and quickly and switching traffic as fast as possible throughout the internet






10. DENY IP 224.0.0.0 15.255.255.255 ANY






11. Protects against repeating of secure sessions






12. Time can be changed - Routing Table can be killed






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






14. The environment - catastrophic events an unauthorized access






15. DENY IP <Network ID> <Network WC Mask> ANY






16. Service Provider


17. Layer 5






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






19. Layer 3






20. Release Number






21. 1300-1999






22. Mode where only the payload of the IP packet is encrypted and/or authenticated






23. ACK and RST






24. Cryptographic protocols that provide secure communications on the Internet for such thing as WWW - email - faxing - IM - and other data transfers






25. Command used to disable NTP on an interface






26. This layer controls user and workgroup acess to the Internetwork resources at the local level using segmentation of networks to create separate collision domains - AKA an organization's trusted network






27. Uses SSL port 443






28. Smurf attacks - can enumerate the network






29. An alternative for both standard and extended ACLs that allow you to refer to an ACL by a descriptive name instead of a number






30. Access-list <number <deny | permit> source source-wildcard source-qualifier destination dest-wildcard dest-qualifier <log | log-input>






31. Allows the source IP host to specify a route through the IP network






32. 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






33. Command to disable CDP on a router






34. Attack that involves a multitude of compromised system attack a single target - denying service to it by exploiting one 'master' system that communicates with other 'zombie' systems






35. What Transport Mode is used for






36. These ACLs filter by network or host IP addresses andspecific protocol type or port numbers - filters by source and destination






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






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






39. Buffer Overflow






40. Permits a host on one LAN segment to initiate a physical broadcast on a different LAN segment






41. Dialer List - Routing Maps - Dynamic Routing Protocols - Controlling Remote Access - NAT'ing - Traffic Filtering






42. Protocol used to keep their time-of-day clocks accurate and in sync






43. 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






44. Minor Version






45. TCP and UDP Port 161






46. DENY IP 127.0.0.0 0.255.255.255 ANY






47. No Known Vulnerability






48. Command to disable UDP small server on a router






49. Layer 3






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