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. Command used to disable the ICMP message Redirect






2. Command used to disable NTP on an interface






3. Access - Distribution - Core






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






5. When a router acts as an intermediary for ARP queries on selected interfaces and enabling transparent access between multiple LAN segments






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






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






8. DENY IP ANY HOST <Broadcast Address>






9. Minor Version






10. Allows packets to be filtered based on upper-layer session information - only uses extended temporary ACL's and must be named - applied on border routers






11. 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






12. 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






13. 0-99






14. Uses only host keys to authenticate systems






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






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






17. 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






18. Commands to disable Finger Server






19. Attack that involves sending a packet to the router with the same IP address in the source and destination address fields - as well as the same port number in the source and destination port field - causing a denial of service






20. 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






21. Service Provider

22. 1300-1999






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






24. Buffer Overflow






25. Plaintext






26. Protocol that allows data to be exchanged using a secure channel between two computers via encryption






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






28. Provides confidentiality - so it cannot be read by unauthorized parties






29. Release Train Identifier






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






31. None - uses attached application protocol's port






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






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






34. Forces the user to enter both a valid username and password






35. Layer 3






36. Command to disable BOOTP Server






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






38. Data link layer protocol used for tunneling network traffic between two peers over an existing network - often used with IPsec to secure packets






39. Block spoofed IP packets - block loopback packets - block IP multicast if unused - block ICMP redirects - Block telnet if not used






40. Enterprise

41. Command used to disable HTTP Server






42. UDP Port 514

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






47. DENY TCP ANY HOST <IP Address> EQ 23






48. Public IP address after translation






49. 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






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