A network administrator is tuning the screen settings on a Junos device. The administrator wants to detect a TCP SYN flood that sends a high rate of SYN packets over a short period. Which parameter should be adjusted to control the sensitivity of the detection?

The alarm-threshold for the SYN flood screen

The zone where the screen is applied

After defining a screen object, how do you apply it to a security zone?

set security policies from-zone to-zone screen

set security zones security-zone screen

An administrator is configuring a screen to protect against IP spoofing on the external zone. The administrator wants to ensure that packets with spoofed source addresses are dropped. Which configuration is correct?

Use the 'ip-spoofing' option in a firewall filter.

Create a screen object with the 'ip-spoofing' option and apply it to the external zone.

Enable the 'ip-spoofing' option globally on the device.

Create a security policy that denies traffic from spoofed addresses.

A junior administrator asks why the security device has a feature called 'screens' and how it differs from security policies. Which statement correctly explains the purpose of screens?

Screens are used to filter traffic based on source and destination IP addresses.

Screens are used to block specific applications from being used.

Screens are used to encrypt traffic between zones.

Screens provide a set of predefined and customizable protections against network-based attacks, applied at the zone level.

Which operational command displays the screens applied to each security zone?
