- C . the CIDR address
- D . the IP address of the device management port
D
Explanation:
J-Web is a web-based interface for configuring and managing Juniper devices. The management and loopback address configuration option in J-Web allows you to configure the IP address of the device management port, which is used to remotely access and manage the device.
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?
- A . IPsec
- B . static NAT
