Free Juniper JN0-231 Exam Actual Questions

Note: Premium Questions for JN0-231 were last updated On Jun. 05, 2024 (see below)

Question #1

An application firewall processes the first packet in a session for which the application has not yet been identified.

In this scenario, which action does the application firewall take on the packet?

Reveal Solution Hide Solution
Correct Answer: D

This is necessary to ensure that the application firewall can properly identify the application and the correct security policies can be applied before allowing any traffic to pass through.

If the first packet was allowed to pass without first being identified, then the application firewall would not know which security policies to apply - and this could potentially lead to security vulnerabilities or breaches. So it's important that the first packet is held until the application is identified.


Question #2

Your company is adding IP cameras to your facility to increase physical security. You are asked to help protect these loT devices from becoming zombies in a DDoS attack.

Which Juniper ATP feature should you configure to accomplish this task?

Reveal Solution Hide Solution
Correct Answer: D

Juniper ATP should be configured with C&C feeds that contain lists of malicious domains and IP addresses in order to prevent IP cameras from becoming zombies in a DDoS attack.

This is an important step to ensure that the IP cameras are protected from malicious requests - and thus, they will not be able to be used in any DDoS attacks against the facility.

Question #5

Which two non-configurable zones exist by default on an SRX Series device? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, C

Junos-host and null are two non-configurable zones that exist by default on an SRX Series device. Junos-host is the default zone for all internal interfaces and services, such as management and other loopback interfaces. The null zone is used to accept all traffic that is not explicitly accepted by other security policies, and is the default zone for all unclassified traffic. Both zones cannot be modified or deleted.
