Answer:
a. make multiple fixes.
Explanation:
When we are troubleshooting firewalls we should not make multiple fixes after attempting a fix because it will not be beneficial for the security purpose.
We can repeat the failure after attempting the fix because we can fix it but a person with right mind won't be doing that.
We can test after each attempt that it is working properly.
We can also reverse or undo the solution failures after making a fix.
In some ways yes but others... not so much. we have access to amazing things that can help so many people and some are tearing people apart or are used for illegal things. its really everyone's own opinion because of some interactions (positive or negative) that can influence them.
I think it’s thrust good luck
