Huawei HCIP-Security V4.0 Sample Questions (Q47-Q52):

NEW QUESTION # 47
Multiple links can be deployed at the egress of an enterprise network to improve network reliability.

A. FALSE
B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
* Deploying multiple egress linksensures:
* Redundancy# If one link fails, another remains active.
* Load balancing# Traffic can be distributed across multiple links.
* High availability# Reduces downtime.
* Why is this statement true?
* Enterprise networksbenefit from multiple egress links.

NEW QUESTION # 48
On a WLAN where the WAC has Portal authentication configured, VLAN authorization can be implemented with no additional configuration required. After Portal authentication is complete, the WAC forwards STA traffic based on the authorized VLANs.

A. TRUE
B. FALSE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
* VLAN authorization in Portal authentication requires additional configuration.
* To assign VLANs dynamically:
* RADIUSmust return VLAN attributesafter authentication.
* TheWAC (Wireless Access Controller) must be configured to support dynamic VLAN assignment.
* Why is this statement false?
* VLAN authorization requires RADIUS attributes and WAC configuration-it is not automatic.

NEW QUESTION # 49
When Eth-Trunk is deployed for the heartbeat links between firewalls, the Eth-Trunk interface can be configured as a Layer 2 interface as long as the total bandwidth of active links on the Eth-Trunk is greater than 30% of the bandwidth required by service traffic.

A. TRUE
B. FALSE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
* Heartbeat linksbetween firewalls ensuresynchronization and failover.
* Layer 2 or Layer 3 configuration depends on deployment needs, but there isno strict 30% bandwidth rulefor Eth-Trunk heartbeat links.
* Why is this statement false?
* The30% threshold condition is incorrect.
* Eth-Trunk heartbeat links aretypically Layer 3 for better failover and routing control.

NEW QUESTION # 50
HWTACACS is a centralized information exchange protocol based on the client/server structure. It uses UDP for transmission and performs authentication, authorization, and accounting for users accessing the Internet through Point-to-Point Protocol (PPP) or Virtual Private Dial-up Network (VPDN) and administrative users logging in to devices.

A. TRUE
B. FALSE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
1##Understanding 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:
A screenshot of a computer AI-generated content may be incorrect.

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.

NEW QUESTION # 51
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.

Answer:

Explanation:

Explanation:
Intrusion Prevention Systems (IPS) in firewalls follow amulti-step processto detect and mitigate threats. The steps occur in a logical sequence:
1##Step 1: Identifies and Parses Application-Layer Protocols
* The firewall firstidentifies the protocol being used(e.g., HTTP, FTP, DNS, SMTP).
* Parsing the protocol helps the IPS engineunderstand how the data is structuredand what types of attacks might be embedded.
* This step is crucial for detectingprotocol-based attackslike SQL injection or cross-site scripting (XSS).
2##Step 2: Reassembles IP Fragments and TCP Flows
* Attackers oftensplit malicious payloads across multiple packetsto evade detection.
* The firewallreassembles fragmented packets and TCP flowsto reconstruct the full data stream.
* This step is critical for detectingevasion techniques such as fragmented attacks or out-of-order packet attacks.
3##Step 3: Performs Signature Matching
* Once the full data stream is reassembled, the IPScompares it against known attack signatures.
* Signature matching helps detect:
* Malware patterns(e.g., botnets, Trojans).
* Exploits targeting vulnerabilitiesin software and operating systems.
* Firewalls usepredefined signature databasesthat are regularly updated.
4##Step 4: Performs the Response Action Based on the IPS Profile
* If an attack is detected, the firewall takes anaction based on the IPS policy:
* Block the traffic(drop malicious packets).
* Alert the administrator(generate logs and alerts).
* Rate-limit traffic(slow down potential attack sources).
* Theresponse mechanism is customizablebased on security requirements.
