The correct answer is B. Select NATed network, Enter public IP of the server or appliance to add. When adding a managed host behind NAT, you must select the NATed network (to tell the system which NAT configuration applies) and enter the public IP of the host - because NAT maps private internal IPs to a publicly routable address, and that public IP is what the management…

Question

An administrator would like to add a new managed host which uses an existing Network Address Translation (NAT). Which parameters have to be provided if "Host is NATed" is chosen while adding a managed host?

Options

  • ASelect Network Attached Telemetric, Enter MAC address of the server or appliance to add
  • BSelect NATed network, Enter public IP of the server or appliance to add
  • CSelect NATed network, Enter MAC address of the server or appliance to add
  • DSelect Network Attached Telemetric, Enter public IP of the server or appliance to add

Explanation

When adding a managed host behind NAT, you must select the NATed network (to tell the system which NAT configuration applies) and enter the public IP of the host - because NAT maps private internal IPs to a publicly routable address, and that public IP is what the management system uses to reach the host across the network boundary.

Why the distractors are wrong:

  • A & D both reference "Network Attached Telemetric," which is a fabricated term - it has no meaning in NAT or host management contexts.
  • C is close but wrong: MAC addresses are Layer 2 identifiers that don't traverse routed/NATed boundaries, so they cannot be used to reach a host across a NAT.

Memory tip: Think of NAT as a "translator at the door." To send mail to a NATed host, you use the public address on the door (public IP), not the internal room number (private IP) or the door's serial number (MAC). When configuring, you always tell the system which door (NATed network) and what's written on it (public IP).
