1.An administrator wants to configure Dead Peer Detection (DPD) on IPSEC VPN for detecting dead tunnels. The requirement is that FortiGate sends DPD probes only ******when no traffic is observed****** in the tunnel. Which DPD mode on FortiGate will meet the above requirement?
A. Disabled
B. On Demand
C. Enabled
D. On Idle
Answer: D Explanation: The Dead Peer Detection (DPD) mode on FortiGate that will meet the requirement of sending DPD probes only when no traffic is observed in the tunnel is "On Idle." Therefore, the correct answer is: D. On Idle Disabled: DPD is turned off. No detection probes are sent. On Demand: DPD probes are sent when there is no traffic detected in the tunnel for a specified period. Enabled: DPD probes are sent periodically, regardless of whether there is traffic in the tunnel or not.

2.An administrator wants to configure dead peer detection (DPD) on IPsec VPN for detecting dead tunnels. The requirement is that FortiGate sends DPD probes only ******when there is outbound traffic***** but no response from the peer. Which DPD mode on FortiGate meets this requirement?
A. On Demand
B. On Idle
C. Disabled
D. Enabled
Answer: A Explanation: The On Demand mode for Dead Peer Detection (DPD) on FortiGate sends DPD probes ******only when there is outbound traffic and no response from the peer******. This mode is used to detect if the peer is still available without continuously sending DPD probes, reducing unnecessary traffic.

C. Disabled
D. On Demand
Answer: B
Explanation:

It's On Demand because in the question it's DPD required if no Inbound traffic. On idle is DPD probes are sent when there is no traffic
