Which statement about IPsec tunnels is true?

You must allow applications to connect to external servers. The session has embedded IP address information to enable the remote system to establish a return session.
In your design, which function should be implemented?

You are working on a network design that will use EX Series devices as Layer 2 access switches in a campus environment. You must include Junos Space in your design. You want to take advantage of security features supported on the devices.
Which two security features would satisfy this requirement? (Choose two.)

You are designing an enterprise WAN network that must connect multiple sites. You must provide a design proposal for the security elements needed to encrypt traffic between the remote sites. Which feature will secure the traffic?

You are creating a data center security design. Virtual security functions must be performed on east-west traffic. Security functions must be commissioned and decommissioned frequently, and the least resource- intensive architecture must be used.
In this scenario, what will accomplish this task?
