Huawei HCIP-Security V4.0 - H12-725_V4.0무료 덤프문제 풀어보기
In the figure, FW_A connects to FW_B through two links working in active/standby mode. When the active link of FW_A is faulty, the old IPsec tunnel 1 needs to be torn down, and IPsec tunnel 2 needs to be established with FW_B through the standby link to route traffic. In this case, configuring the IKE _____ detection mechanism on FW_A helps detect link faults and tear down the IPsec tunnel.(Enter lowercase letters.)


정답:
dpd
Explanation:
* What is IKE DPD (Dead Peer Detection)?
* IKE DPD (Dead Peer Detection)is a mechanism used inIPsec VPNsto check if a remote VPN peer is still reachable.
* It allows the firewall to detectlink failuresandautomatically tear down and re-establish IPsec tunnelswhen necessary.
* Why is DPD required in this scenario?
* The network uses an active/standby link setup:
* IPsec Tunnel 1 (Active) # Uses Link 1 (GE0/0/1).
* IPsec Tunnel 2 (Standby) # Uses Link 2 (GE0/0/2).
* IfLink 1 fails, the firewall must detect the failure andtear down IPsec Tunnel 1before establishingIPsec Tunnel 2 over Link 2.
* DPD detects unreachable peersand triggers a failover.
* How does IKE DPD work?
* DPD periodically sends probes (HELLO messages) to the remote VPN peer.
* If no response is received within a timeout period, the firewall assumes the peer is down.
* Thefirewall deletes the IPsec tunnel and switches to the backup link.
* Why is the answer "dpd" (lowercase)?
* The questionexplicitly asks for lowercase letters.
* "dpd" (Dead Peer Detection) is the correct technical term in Huawei firewalls and networking standards.

The difference between DoS attacks and DDoS attacks is that DoS attacks are usually directly initiated by attackers, whereas DDoS attacks are usually initiated by attackers controlling multiple zombies.
