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. Public IP address before translation






2. 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






3. ACK and RST

6. DENY IP 127.0.0.0 0.255.255.255 ANY






7. Device - Hostname - IOS - IP Address - Ports - Model






8. Uses only host keys to authenticate systems






9. Router threat that includes manipulating router updates to cause traffic to flow to unauthorized destinations






10. 33400-34400






11. Attack that involves transmitting a volume of connections that cannot be completed at the destination - causing the queue to fill up and denying service to legitimate user






12. Layer 3






13. When one network protocol called the payload protocol is encapsulated within a different delivery network - or provide a secure path through an untrusted network






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






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






16. Local and Remote






17. Router to Router Denial of Service






18. 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






19. DENY IP HOST <Inbound IP Address> HOST <Inbound IP Address>






20. A method of bypassing firewall or proxy restrictions by making the firewall think that it is getting traffic from a web browser






21. The communication layer between the two other layers and provides network security - including ACLs - firewalls - any general public access servers and address translation; also known as the isolation LAN or DMZ






22. None - uses attach application protocol's layer






23. What Local and Global refer to in NAT






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






25. Layer 3






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






27. Command to disable BOOTP Server






28. Can copy - poison - corrupt - or delete the IOS






29. Command to disable UDP small server on a router






30. Accounts without passwords - Type 7 encryption - account privilege higher than 1 - able to be fingered






31. Refers to the organization's private network






32. 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

38. Can obtain CIDR and router ID






39. TCP and UDP Port 162






40. Breaks LAN security perimeter extends LAN to Layer 2






41. Must be made at global config mode - created from CON/VTY session or text file - read top to bottom - applied at the interface and only one ACL per direction - per protocol - per interface






42. These ACLs filter by network or host IP address and only filter on source






43. Protects against repeating of secure sessions






44. Public IP address after translation






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