Exam Prep Questions

[ LiB ]  
Question 1

Which command do you use to add a user 's public key to a sensor to enable RSA authentication?

  • A. tls generate-key

  • B. ssh authorized-key

  • C. ssh client-key

  • D. ssh host-key

A1:

Answer B is correct. The ssh authorized-key command allows the currently logged-on user to add his or her public key to the sensor. Answer A is incorrect because you use tls generate-key to create a new sensor certificate. Answer C is incorrect because the command does not exist. Answer D is incorrect because you use the ssh host-key command to add keys to the trusted host list.

Question 2

Which command helps you configure the sensor's IP address?

  • A. interface IP address

  • B. sensor IP address

  • C. interface command-control

  • D. interface sensing

A2:

Answer C is correct. The interface command-control command navigates you to the interface configuration level. From there, you can execute the IP address command. Answers A and B are incorrect because these commands do not exist. Answer D is incorrect because the interface sensing command allows you to configure sensing interfaces. However, remember that sensing interfaces do not have IP addresses.

Question 3

If you want to replace the current running configuration with the backup configuration stored on the sensor, which command do you use?

  • A. copy current-config backup-config

  • B. copy /erase current-config backup-config

  • C. copy backup-config current-config

  • D. copy /erase backup-config current-config

A3:

Answer D is correct. The copy command syntax with the /erase option first deletes the file and then replaces it with the source file. Remember that copy command syntax is copy source destination . Therefore, Answers A, B, and C are incorrect.

Question 4

What command replaces the application partition with the backup partition?

  • A. reset application-partition

  • B. recover application-partition

  • C. reset recovery-partition

  • D. recover application-partition recovery-partition

A4:

Answer B is correct. The recover command replaces the application partition with the recovery partition. Answers A and C are incorrect because they use the reset command, which you only use to shut down or reboot the sensor. Answer D uses the incorrect syntax for the recovery command and therefore is incorrect.

Question 5

Which command adds trusted hosts entries to the sensor?

  • A. ssh host-key

  • B. ssh host

  • C. ssh host IP address

  • D. ssh authorized-key

A5:

Answer A is correct. The ssh host-key command adds entries to the sensor's trusted host list. Answer B and C are invalid commands. Answer D is incorrect; you use the ssh authorized-key command to add user public keys to the sensor for RSA authentication.

Question 6

What command copies the running configuration to an FTP server?

  • A. copy backup-config ftp://192.168.1.10/backup-config

  • B. copy current-config ftp://192.168.1.10/backup-config

  • C. copy ftp://192.168.1.10/backup-config current-config

  • D. copy ftp://192.168.1.10/backup-config backup-config

A6:

Answer B is correct. The syntax for the copy command is copy source destination . The question talks about the running configuration, which relates to the current-config file, not the backup-config file. Therefore, Answers A, C, and D are incorrect.

Question 7

What happens when a user with a privilege level of viewer executes the show user all command?

  • A. It displays all users currently logged on.

  • B. It displays only users with the viewer privilege level.

  • C. It displays all user configured on the sensor.

  • D. It does not work.

A7:

Answer D is correct. This command option of all is not allowed by users with the viewer privilege level. You must be an administrator or operator to execute this command. In addition, when executed, the command displays all users configured on the sensor. Therefore, Answers A, B, and C are incorrect.

Question 8

Which command changes the privilege level of tina from administrator to operator?

  • A. privilege user tina level operator

  • B. privilege user tina operator

  • C. privilege tina level operator

  • D. privilege tina operator

A8:

Answer B is correct. The privilege command allows you to change a user privilege level if you are currently logged on as the administrator. Answers A, C, and D are incorrect syntax for the command and are therefore incorrect.

Question 9

Which command removes the current-config?

  • A. clear current-config

  • B. reset current-config

  • C. erase current-config

  • D. delete current-config

A9:

Answer C is correct. The erase command allows you to remove the current-config or the backup-config files. If you remove the current-config files, the sensor resets everything, except user accounts, back to default values. Answers A, B, and D are incorrect syntax of other commands and are therefore incorrect.

Question 10

Which command shuts down all sensor programs and applications and prepares the sensor for shutdown?

  • A. powerdown

  • B. reset

  • C. reset powerdown

  • D. reset poweroff

A10:

Answer C is correct. The reset command with the powerdown option shuts down all programs and shuts down the sensor. Answer A is incorrect because the powerdown command does not exist. Answer B is incorrect because it shuts down the programs before rebooting the sensor. Answer D is incorrect because the command does not exist.
