A user cannot open the website www.example.com. The following diagnostics are recorded: - Ping to 8.8.8.8: average 32 ms, 0 % packet loss. - Ping to the website's IP (93.184.216.34): average 150 ms, 20 % packet loss. - nslookup of www.example.com returns the IP 93.184.216.34. - Traceroute to the website shows a delay of 200 ms at hop 3. The network firewall blocks TCP port 80 for any MAC address not listed in its allowed‑MAC table, and the user's MAC address is currently absent from that list. Assuming each remedial step (adding the MAC address to the firewall, clearing the DNS cache, and restarting the NIC) takes exactly 2 minutes, identify the most probable cause of the problem and calculate the minimum total time required to restore access.
