Check Point Certified Security Administrator (CCSA) R80 — Question 10

When using GAiA, it might be necessary to temporarily change the MAC address of the interface eth 0 to 00:0C:29:12:34:56. After restarting the network the old MAC address should be active. How do you configure this change?

Answer options

• A. As expert user, issue these commands: # IP link set eth0 down # IP link set eth0 addr 00:0C:29:12:34:56 # IP link set eth0 up
• B. Edit the file /etc/sysconfig/netconf.C and put the new MAC address in the field (conf :(conns :(conn :hwaddr (ג€00:0C:29:12:34:56ג€)
• C. As expert user, issue the command: # IP link set eth0 addr 00:0C:29:12:34:56
• D. Open the WebUI, select Network > Connections > eth0. Place the new MAC address in the field Physical Address, and press Apply to save the settings.

Correct answer: C

Explanation

The correct answer is C because it directly sets the MAC address of eth0 to the desired value without additional steps. Options A and D involve unnecessary steps that do not achieve the temporary MAC address change as simply as option C does. Option B modifies a configuration file, which is not the immediate command-based approach required for this task.
