A server in the DMZ of your company is under attack. The attacker is opening a large number of
TCP connections to your server which causes resource utilization problems on the server. All of
the connections from the attacker appear to be coming from a single IP address.
Referring to the exhibit, which Junos Screen option should you enable to limit the effects of the
attack while allowing legitimate traffic?

Refer to the Exhibit.

Referring to the exhibit, you want to use source NAT to translate the Web server’s IP address to
the IP address of ge-0/0/2.
Which source NAT type accomplishes this task and always performs PAT?

You have implemented source NAT using a source pool for address translation. However, traffic
destined for 192.150.2.140 should not have NAT applied to it. The configuration shown in the
exhibit is not working correctly.
Which change is needed to correct this problem?

Refer to the Exhibit.
