1. Imagine that you have configured the enable secret command, followed by the enable password command, from the console. You log out of the switch and log back in at the console. Which command defines the password that you had to enter to access privileged mode?
a. enable password b. enable secret c. Neither d. The password command, if it’s configured
2. Some IOS commands store passwords as clear text, but you can then encrypt the passwords with the service password-encryption global command. By comparison, other commands store a computed hash of the password, rather than storing the password. Comparing the two options, which one answer is the most accurate about why one method is better than the other?
a. Using hashes is preferred because encrypted IOS passwords can be easily decrypted. b. Using hashes is preferred because of the large CPU effort required for encryption. c. Using encryption is preferred because it provides stronger password protection. d. Using encryption is preferred because of the large CPU effort required for hashes.
3. A network engineer issues a show running-config command and sees only one line of output that mentions the enable secret command, as follows:
enable secret 5 $1$ZGMA$e8cmvkz4UjiJhVp7.maLE1--Which of the following is true about users of this router?--
a. A user must type $1$ZGMA$e8cmvkz4UjiJhVp7.maLE1 to reach enable mode. b. The router will hash the clear-text password that the user types to compare to the hashed password. c. A no service password-encryption configuration command would decrypt this password. d. The router will decrypt the password in the configuration to compare to the clear-text password typed by the user.
4. The following command was copied and pasted into configuration mode when a user was telnetted into a Cisco switch:
banner login this is the login banner--Which of the following is true about what occurs the next time a user logs in from the console?--
a. No banner text is displayed. b. The banner text “his is ” is displayed. c. The banner text “this is the login banner” is displayed. d. The banner text “Login banner configured, no text defined” is displayed.
5. A single-line ACL has been added to a router configuration using the command ip access-list 1 permit 172.16.4.0 0.0.1.255. The configuration also includes the ip access-class 1 in command in VTY configuration mode. Which answer accurately describes how the router uses ACL 1?
a. Hosts in subnet 172.16.4.0/23 alone can telnet into the router. b. CLI users cannot telnet from the router to hosts in subnet 172.16.4.0/23 alone. c. Hosts in subnet 172.16.4.0/23 alone can log in but cannot reach enable mode of the router. d. The router will only forward packets with source addresses in subnet 172.16.4.0/23.

a. Use the copy ftp flash command to copy files into flash using FTP. b. Use the copy flash tftp command to copy files using TFTP into flash. c. Use the copy scp flash command to copy files into flash using SCP. d. Use the ios restore command to copy files into flash from the file archive.
2. What is the first step a typical Cisco router takes during the boot process when attempting to locate an operating system to load?
a. The router looks for an image on a TFTP server. b. The router checks its configuration register boot field. c. The router boots to ROMMON. d. The router looks in flash memory for a Cisco IOS image file.
