Question 1

At Woodgrove Bank, a network administrator is handling a FortiGate 7.6 change. The requirement is to publish an internal server on a different external IP address. What should the administrator do? The administrator wants a configuration that is easy to audit later.

Use separate port-forwarding VIPs or mappings for the required external-to-internal port combinations
Enable port forwarding on the VIP and map the external service port to the required internal port
Create a virtual IP mapping and reference that VIP as the destination of the inbound firewall policy
Inspect the VIP mapped address and port configuration rather than the public destination alone
Create or correct the inbound firewall policy that references the VIP and allows the required service

Correct answer: C

Explanation

Port-forwarding VIPs allow different services to share a public address while using distinct external ports. This can be appropriate in a different FortiGate situation, but it does not directly satisfy the stated requirement to publish an internal server on a different external IP address.
VIP port forwarding performs destination address and port translation for the published service. This can be appropriate in a different FortiGate situation, but it does not directly satisfy the stated requirement to publish an internal server on a different external IP address.
A VIP performs destination translation and the policy authorizes traffic to the mapped server. This directly satisfies the stated requirement.
The VIP defines the internal destination FortiGate uses after matching the external address or port. This can be appropriate in a different FortiGate situation, but it does not directly satisfy the stated requirement to publish an internal server on a different external IP address.

VIP port forwarding performs destination address and port translation for the published service. This can be appropriate in a different FortiGate situation, but it does not directly satisfy the stated requirement to ensure a VIP is intended to match traffic arriving on a particular WAN.
Successful DNAT still depends on matching ports, policy, server availability, and a valid return path. This can be appropriate in a different FortiGate situation, but it does not directly satisfy the stated requirement to ensure a VIP is intended to match traffic arriving on a particular WAN.

Question 20

Trey Research has validated routing and basic reachability. The remaining requirement is to understand why creating a VIP alone did not make the server reachable. Which action should the team take? The choice should follow normal FortiOS administration practice.

Create or correct the inbound firewall policy that references the VIP and allows the required service
Inspect the VIP mapped address and port configuration rather than the public destination alone
Check the mapped port, inbound policy service, server listener, return route, and any required source-NAT behavior
Set the VIP external interface appropriately for the deployment and use it in the matching inbound policy
Use separate port-forwarding VIPs or mappings for the required external-to-internal port combinations

Correct answer: A

Question 21

At Nod Publishers, a network administrator is handling a FortiGate 7.6 change. The requirement is to troubleshoot a VIP that translates to the right host but the service still times out. What should the administrator do? The solution must preserve the existing production design where possible.

Use separate port-forwarding VIPs or mappings for the required external-to-internal port combinations
Verify the VIP for DNAT and independently verify policy or central SNAT settings for any source translation
Inspect the VIP mapped address and port configuration rather than the public destination alone
Create a virtual IP mapping and reference that VIP as the destination of the inbound firewall policy
Check the mapped port, inbound policy service, server listener, return route, and any required source-NAT behavior

Correct answer: E
