Huawei HCIP-Security V4.0 Sample Questions (Q14-Q19):

NEW QUESTION # 14
Which of the following operations can be performed to harden the Windows operating system?(Select All that Apply)

A. Restrict the number of users.
B. Change the default TTL value.
C. Periodically check account permissions.
D. Cancel default sharing.

Answer: A,C,D

Explanation:
Comprehensive and Detailed Explanation:
* Windows system hardening improves security by reducing attack surfaces.
* Recommended security measures include:
* A. Periodically checking account permissions# Prevents unauthorized access.
* B. Canceling default sharing# Reduces exposure to remote attacks.
* C. Restricting the number of users# Limits access to essential personnel.
* Why is D incorrect?
* Changing the default TTL value does not directly enhance system security.

NEW QUESTION # 15
Network Access Control (NAC) is an end-to-end security control technology that works in combination with AAA to implement access authentication. Which of the following statements about NAC and AAA are true?(Select All that Apply)

A. An AAA server controls network access rights of users through authentication, authorization, and accounting.
B. NAC is mainly used for interaction between access devices and authentication servers.
C. AAA is mainly used for interaction between users and access devices.
D. NAC provides three authentication modes: 802.1X authentication, MAC address authentication, and Portal authentication.

Answer: A,B,C,D

Explanation:
Comprehensive and Detailed Explanation:
* Network Access Control (NAC) and AAA work together for secure network access.
* Key functions:
* A. AAA handles user-to-device authentication.
* B. NAC handles device-to-server authentication.
* C. NAC supports 802.1X, MAC authentication, and Portal authentication.
* D. AAA enforces authentication, authorization, and accounting.
* Why are all options correct?

NEW QUESTION # 16
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 # 17
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.

NEW QUESTION # 18
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.
