Refer to the exhibit. An administrator notes a significant increase in the amount of traffic entering the network from the ISP. The administrator clears the access-list counters. After a few minutes, the administrator again checks the access-list table. What can be concluded from the most recent output shown?
- A small amount of HTTP trafic is an indication that the web server was not configured correctly.
- A larger amount of POP3 traffic (compared with SMTP traffic) indicates that there are more POP3 email clients than SMTP clients in the enterprise.
- A large amount of ICMP traffic is being denied at the interface, which can be an indication of a DoS attack.
- A larger amount of email traffic (compared with web traffic) is an indication that attackers mainly targeted the email server.
