Huawei HCIP-Security V4.0 Sample Questions (Q54-Q59):

NEW QUESTION # 54
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.

NEW QUESTION # 55
Which of the following is the function of Message 1 and Message 2 during IKEv1 phase-1 negotiation in main mode?

A. Negotiation of the IKE proposals used between peers
B. Mutual identity authentication
C. Exchange of key-related information (materials used for key generation) using the DH algorithm and generation of keys
D. IPsec SA negotiation

Answer: A

Explanation:
Comprehensive and Detailed Explanation:
* IKEv1 Phase 1 (Main Mode) consists of six messages:
* Messages 1 & 2 # Negotiate security proposals(encryption, authentication, and DH group).
* Messages 3 & 4 # Exchange key-related information.
* Messages 5 & 6 # Perform mutual authentication.
* Why is B correct?
* Messages 1 and 2 negotiate IKE proposalsbetween VPN peers.

NEW QUESTION # 56
Which of the following statements is false about virtual system resource allocation?

A. Virtual systems can share and preempt resources of the entire device. Such resources can be manually allocated.
B. To manually allocate resources to a virtual system, an administrator needs to configure a resource class, specify the guaranteed quota and maximum quota of each resource in the resource class, and bind the resource class to the virtual system.
C. Quota-based resources are automatically allocated based on system specifications.
D. Improper resource allocation may prevent other virtual systems from obtaining resources and services from running properly.

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
* Virtual system resource allocation can bemanual or shared.
* Manual allocationrequires configuring aresource class, defining aquota, and binding it to a virtual system.
* Why is D false?
* Quota-based resources are not automatically allocated.
* An administrator must defineresource quotas.

NEW QUESTION # 57
In a Huawei network security environment, which of the following is a key advantage of using HWTACACS over RADIUS for device management authentication?
Options:

A. HWTACACS does not support accounting, while RADIUS does.
B. HWTACACS encrypts only passwords, while RADIUS encrypts the entire payload.
C. HWTACACS operates over UDP, ensuring faster communication than RADIUS.
D. HWTACACS provides per-command authorization, allowing different privilege levels for different users.

Answer: D

Explanation:
Understanding the Differences Between HWTACACS and RADIUS:
* HWTACACS(Huawei Terminal Access Controller Access-Control System) is aHuawei-enhanced version of TACACS+used forAAA (Authentication, Authorization, and Accounting).
* RADIUS (Remote Authentication Dial-In User Service)is also an AAA protocol but is mainly designed fornetwork access authentication, such asVPNs and wireless authentication.
Why is Option B Correct?
* HWTACACS supports per-command authorization, meaning administrators canassign different command privileges to different users.
* For example, ajunior network engineer may be allowed to view configurations but not modify them
, while asenior engineer has full access.
* RADIUS does not support granular command authorization, as it primarily controlsnetwork access rather than device management.
