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 operates over UDP, ensuring faster communication than RADIUS.
- C. HWTACACS provides per-command authorization, allowing different privilege levels for different users.
- D. HWTACACS encrypts only passwords, while RADIUS encrypts the entire payload.
Answer: C
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.

- B. When the size of the uploaded or downloaded file or the size of the content obtained through the POST operation reaches the alarm threshold, the system generates a log to notify the device administrator and block the behavior.
- C. The POST method of HTTP is commonly used to send information to the server through web pages.For example, use this method when you post threads, submit forms, and use your username and password to log in to a specific system.
- D. When the size of the uploaded or downloaded file or the size of the content obtained through the POST operation reaches the block threshold, the system blocks the uploaded or downloaded file or POST operation.
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
* Threshold settings in firewalls allow administrators to define:
* Alarm threshold# When exceeded, logs are generated.
* Block threshold# When exceeded, the action is blocked.
* Why is B false?
* The alarm threshold does not block traffic; it only generates logs.
* Only the block threshold enforces blocking actions.

NEW QUESTION # 22
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.

Match the description about virtual systems and VPN instances.
Answer:
Explanation:
Explanation:
1. Virtual System # Services and routes can be isolated.
* A virtual system (VS)in Huawei firewalls is afully isolated security instancewithin a single physical firewall.
* Each virtual system hasseparate services, routing tables, policies, and security rules, ensuring full isolation between different users or tenants.
2. VPN Instance # Only route isolation can be implemented.
* AVPN instance (VRF - Virtual Routing and Forwarding)providesroute isolationfor different customer networks butdoes not isolate services or security policies.
* This is typically used inMPLS VPN deploymentswhere different customers share the same physical device but need isolated routing tables.
3. VPN Instance # VPN instances are automatically generated.
* In someMPLS VPNorSDN-managed networks, VPN instances can beautomatically createdwhen customer configurations are pushed via controllers.
* Dynamic routing protocols (e.g., BGP/MPLS VPN) can automatically generateVRF instancesbased on network policies.
4. Virtual System # An instance needs to be manually created.
* Unlike VPN instances,virtual systems must be manually createdby an administrator on the firewall.
* Each virtual system functions as acompletely independent firewall, requiring manual configuration of interfaces, policies, and routing settings.
