Huawei HCIP-Security V4.0 Sample Questions (Q11-Q16):

NEW QUESTION # 11
Which of the following statements are true about SYN scanning attacks?(Select All that Apply)

  • A. If the peer end does not respond to the SYN packet sent by the scanner, the peer host does not exist, or filtering is performed on the network or host.
  • B. When the scanner sends a SYN packet, a SYN-ACK response indicates an open port.
  • C. When the scanner sends a SYN packet, an RST response indicates a closed port.
  • D. When the scanner sends a SYN packet, if the peer end responds with a SYN-ACK packet, the scanner then responds with an ACK packet to complete the three-way handshake.

Answer: A,B,C

Explanation:
Comprehensive and Detailed Explanation:
* SYN scanning is a stealthy technique used to identify open ports on a target system without fully establishing a TCP connection.
* How SYN scanning works:
* The scanner sends aSYN packetto the target port.
* The target responds based on the port state:
* SYN-ACK # Port is open(Correct - D).
* RST # Port is closed(Correct - A).
* No response # The host does not exist, or a firewall is blocking it(Correct - B).
* The scanner doesnot send an ACK(unlike a full TCP connection). Instead, it sends anRSTto avoid detection.
* Why is C incorrect?
* In SYN scanning, the scanner does NOT send an ACK to complete thehandshake. Instead, it sends an RST to abort the connection.

NEW QUESTION # 14
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.)

Answer:

Explanation:
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.
