  • reconnaissance attacks
  • access attacks
  • denial of service attacks
  • malicious code attacks

7. A network administrator has determined that various computers on the network are infected with a worm. Which sequence of steps should be followed to mitigate the worm attack?

  • inoculation, containment, quarantine, and treatment
  • containment, quarantine, treatment, and inoculation
  • treatment, quarantine, inoculation, and containment
  • containment, inoculation, quarantine, and treatment

8. What is a security feature of using NAT on a network?

  • allows external IP addresses to be concealed from internal users
  • allows internal IP addresses to be concealed from external users
  • denies all packets that originate from private IP addresses
  • denies all internal hosts from communicating outside their own network

9. Refer to the exhibit. Baseline documentation for a small company had ping round trip time statistics of 36/97/132 between hosts H1 and H3. Today the network administrator checked connectivity by pinging between hosts H1 and H3 that resulted in a round trip time of 1458/2390/6066. What does this indicate to the network administrator?

  • Connectivity between H1 and H3 is fine.
  • H3 is not connected properly to the network.
  • Something is causing interference between H1 and R1.
  • Performance between the networks is within expected parameters.
  • Something is causing a time delay between the networks.

10. When should an administrator establish a network baseline?

  • when the traffic is at peak in the network
  • when there is a sudden drop in traffic
  • at the lowest point of traffic in the network
  • at regular intervals over a period of time

11. Refer to the exhibit. An administrator is trying to troubleshoot connectivity between PC1 and PC2 and uses the tracert command from PC1 to do it. Based on the displayed output, where should the administrator begin troubleshooting?

  • The network administrator suspects a virus because the ping command did not work.
  • The network administrator wants to verify Layer 2 connectivity.
  • The network administrator wants to verify the IP address configured on router R2.
  • The network administrator wants to determine if connectivity can be established from a non-directly connected network.

13. Which statement is true about CDP on a Cisco device??

  • The show cdp neighbor detail command will reveal the IP address of a neighbor only if there is Layer 3 connectivity?.
  • To disable CDP globally, the no cdp enable command in interface configuration mode must be used.
  • CDP can be disabled globally or on a specific interface?.
  • Because it runs at the data link layer?, the CDP protocol can only be implemented in switches.

14. What is the purpose of issuing the commands cd nvram: then dir at the privilege exec mode of a router?

  • to clear the content of the NVRAM
  • to direct all new files to the NVRAM
  • to list the content of the NVRAM
  • to copy the directories from the NVRAM

15. If a configuration file is saved to a USB flash drive attached to a router, what must be done by the network administrator before the file can be used on the router?

  • Convert the file system from FAT32 to FAT16.
  • Edit the configuration file with a text editor.
  • Change the permission on the file from ro to rw.
  • Use the dir command from the router to remove the Windows automatic alphabetization of the files on the flash drive.

  • consists of a 32-character string and is not case sensitive
  • responsible for determining the signal strength

  • EAP
  • PSK
  • WEP
  • WPA

20. Which two statements characterize wireless network security? (Choose two.)

  • Wireless networks offer the same security features as wired networks.
  • Some RF channels provide automatic encryption of wireless data.
  • With SSID broadcast disabled, an attacker must know the SSID to connect.
  • Using the default IP address on an access point makes hacking easier.
