  2. Add echo 1 > /proc/sys/net/ipv4/ip_forward to any user login script
  3. In /etc/sysct1.conf change net.ipv4.ip_forward to 1
  4. In /etc/rc.local add net.ipv4.ip_forward = 1

question 35 is incorrect, the correct answer is c, it even states so: explanation: when a vm is infected with ransomware, you should not restore the vm to the infected vm. this is because the ransomware will still be present on the vm, and it will encrypt the files again. you should also not restore the vm to any vm within the companys subscription. this is because the ransomware could spread to other vms in the subscription. the best way to restore a vm that is infected with ransomware is to restore it to a new azure vm. this will ensure that the ransomware is not present on the new vm.
