Pass the Huawei HCIP-Security H12-725_V4.0 Questions and answers with ValidTests

Comprehensive and Detailed Explanation:

Inbound bandwidth= Trafficenteringthe firewall.

Outbound bandwidth= Trafficleavingthe firewall.

Correct answers:B. Public → Private traffic is controlled by inbound bandwidth.D. Private → Public traffic is controlled by outbound bandwidth.

Comprehensive and Detailed Explanation:

Huawei firewalls come with a built-in URL filtering database, which includes predefined categories such as:

Malicious websites

Phishing sites

Social media

Business services

The URL category database is periodically updated by Huawei, ensuring that new threats are detected automatically.

Why is this statement true?

Administrators do not need to manually load URL categories; they are delivered with the firewall and updated regularly.

1️⃣Step 1: Traffic Classification and Bandwidth Policy Matching

The firewallfirst classifies trafficusing predefined bandwidth policies.

These policies match traffic based on criteria such assource/destination IP, application type, and protocol.

This step ensures that each type of traffic is categorized correctly before applying bandwidth restrictions.

2️⃣Step 2: Traffic Processing Based on Bandwidth Policies

Once traffic is classified,the firewall enforces bandwidth limits and security actions:

Traffic exceeding the assigned bandwidth is discarded or throttled.

Service connection limits are enforced to prevent excessive connections per user or application.

3️⃣Step 3: Queue Scheduling and Priority Handling

If trafficexceeds the available bandwidth, the firewallprioritizes high-priority trafficusing queue scheduling mechanisms.

Techniques likeWeighted Fair Queuing (WFQ) and Priority Queuing (PQ)ensure thatcritical traffic (e.g., VoIP, business applications) is prioritized over less important traffic (e.g., downloads, streaming).

1️⃣Understanding HWTACACS:

HWTACACS (Huawei Terminal Access Controller Access-Control System)is aHuawei-proprietaryAAA (Authentication, Authorization, and Accounting) protocol.

It isbased on the TACACS+ protocolbut optimized for Huawei devices.

Why the Statement is False?

The statement contains atechnical inaccuracyabout thetransport protocolused by HWTACACS.

Incorrect:"It uses UDP for transmission."

Correct:HWTACACS uses TCP (Transmission Control Protocol), not UDP.

TACACS+ and HWTACACS both use TCP (port 49) for reliable communication.

Key Features of HWTACACS:

Why TCP is Used Instead of UDP?

TCP ensures reliable deliveryof AAA messages.

UnlikeRADIUS (which uses UDP), HWTACACS does not suffer from packet loss issuessince TCP provides retransmission and flow control.

Where is HWTACACS Used?

Device Login Authentication→ Securely managesnetwork administrators accessing Huawei routers, switches, and firewalls.

Authorization Control→ Grants specific command-level privileges to users.

Accounting→ Logs command execution for auditing purposes.

Comprehensive and Detailed Explanation:

iMaster NCE-Campus does not have a built-in LDAP server.Instead, it integrates with external authentication servers such as:

RADIUS servers

Active Directory (AD) with LDAP

HWTACACS servers

Why is this statement false?

iMaster NCE-Campus can connect to LDAP but does not act as an LDAP server itself.

Comprehensive and Detailed Explanation:

SSL VPN remote access process includes:

User login→ User enters credentials on the virtual gateway.

User authentication→ Credentials are verified via RADIUS, LDAP, or local authentication.

Resource access→ The authenticated user accesses intranet resources.

Why is C incorrect?

SSL VPN does not perform "Access accounting"(which is used in RADIUS-based AAA systems).

Comprehensive and Detailed Explanation:

A Trojan horse is a type of malware that disguises itself as a legitimate applicationto trick users into installing it.

Transmission methods:

A. Exploiting vulnerabilities→ Attackers use system/software vulnerabilities to inject Trojans.

B. Bundled in software→ Trojans are included in cracked software or pirated applications.

C. Downloaded from third-party sites→ Users unknowingly install malware from untrusted sources.

D. Masquerading as useful software→ Fake tools trick users into installation.

Why are all options correct?

All listed methods are common ways Trojans spread.

Comprehensive and Detailed Explanation:

Health checkensuresnetwork reliabilityby detecting link failures.

Supports multiple protocols: ICMP, TCP, UDP, DNS, and HTTP.

Works with PBR (Policy-Based Routing):

Health checkmonitors link status, and if a failure is detected,PBR dynamically switches to an alternate path.

Why is C false?

Health check CAN be used with PBRto ensure traffic is routed via healthy links.
