Question 1 of 109

Which two criteria should a zone-based security policy include? (Choose two.)

Answer

Suggested Answer

The suggested answer is C, D.

Two essential criteria for a zone-based security policy are zone context and an action. The zone context defines the scope within which the rules are applied, specifying the movement of traffic between security zones. An action dictates what is to be done with the traffic that matches the defined criteria, such as allowing or blocking it. These components ensure that traffic is appropriately managed and secure as it traverses the network.

Question 2 of 109

You are assigned a project to configure SRX Series devices to allow connections to your webservers. The webservers have a private IP address, and the packets must use NAT to be accessible from the Internet. You do not want the webservers to initiate connections with external update servers on the Internet using the same IP address as customers use to access them.

Which two NAT types must be used to complete this project? (Choose two.)

Answer

Suggested Answer

The suggested answer is A, D.

To complete this project, you need to use Static NAT and Source NAT. Static NAT ensures that each webserver has a consistent, unchanging public IP address for inbound connections from the Internet, making sure the webservers are accessible. Source NAT is used for outbound connections initiated by the webservers to ensure they do not use the same IP address as the one used for incoming customer traffic. This way, the webservers can initiate connections with external update servers using a different public IP address.

Exam JN0-231: Question 4 - Image 1

Referring to the exhibit, a user is placed in which hierarchy when the exit command is run?

Answer

Suggested Answer

The suggested answer is C.

When the user runs the exit command, they are placed back in the hierarchy level immediately before the last edit command. In this case, the user initially navigated to the 'edit security policies' level and then moved to 'edit from-zone trust to-zone dmz policy Trust-DMZ-Access.' Exiting from the second level brings them back to the 'edit security policies' level.
