Huawei HCIP-Security V4.0 認定 H12-725_V4.0 試験問題 (Q37-Q42):
質問 # 37
Which of the following statements are true about SYN scanning attacks?(Select All that Apply)
- A. When the scanner sends a SYN packet, an RST response indicates a closed port.
- B. When the scanner sends a SYN packet, if the peer end responds with a SYN-ACK packet, the scanner then responds with an ACK packet to complete the three-way handshake.
- C. When the scanner sends a SYN packet, a SYN-ACK response indicates an open port.
- D. If the peer end does not respond to the SYN packet sent by the scanner, the peer host does not exist, or filtering is performed on the network or host.
正解：A、C、D
解説：
Comprehensive and Detailed Explanation:
* SYN scanning is a stealthy technique used to identify open ports on a target system without fully establishing a TCP connection.
* How SYN scanning works:
* The scanner sends aSYN packetto the target port.
* The target responds based on the port state:
* SYN-ACK # Port is open(Correct - D).
* RST # Port is closed(Correct - A).
* No response # The host does not exist, or a firewall is blocking it(Correct - B).
* The scanner doesnot send an ACK(unlike a full TCP connection). Instead, it sends anRSTto avoid detection.
* Why is C incorrect?
* In SYN scanning, the scanner does NOT send an ACK to complete thehandshake. Instead, it sends an RST to abort the connection.

質問 # 38
Trojan horses may disclose sensitive information of victims or even remotely manipulate victims' hosts, causing serious harm. Which of the following are the transmission modes of Trojan horses?(Select All that Apply)
- A. A Trojan horse masquerades as a tool program to deceive users to run the program on a host. Once the program is run, the Trojan horse is automatically implanted into the host.
- B. Attackers exploit vulnerabilities to break into hosts and install Trojan horses.
- C. A Trojan horse is bundled in a well-known tool program.
- D. The software downloaded from a third-party downloader carries Trojan horses.
正解：A、B、C、D
解説：
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.

質問 # 39
Which of the following statements is false about RADIUS and HWTACACS?
- A. Both of them support authorization of configuration commands.
- B. Both of them feature good flexibility and extensibility.
- C. Both of them use the client/server model.
- D. Both of them use shared keys to encrypt user information.
正解：A
解説：
Comprehensive and Detailed Explanation:
* RADIUS and HWTACACS are AAA (Authentication, Authorization, and Accounting) protocols, but they have key differences:
* RADIUS# Encrypts only passwords (not the entire message).
* HWTACACS# Encrypts the entire packet, providing better security.
* Command authorization:
* RADIUS does not support command-level authorization.
* HWTACACS supports per-command authorization(used in network device access control).
* Why is C false?
* RADIUS does not authorize configuration commands; HWTACACS does.

質問 # 40
In the figure, if 802.1X authentication is used for wired users on the network, the network admission device and terminals must be connected through a Layer 2 network.
Options:
正解：A
解説：
Understanding 802.1X Authentication in Wired Networks:
* 802.1X is a port-based network access control (PNAC) protocolthat requires aLayer 2 connection between thesupplicant (PC), the authenticator (switch), and the authentication server (e.g., RADIUS server).
* In wired networks,802.1X authentication occurs at the Ethernet switch (Layer 2 device), which enforces authenticationbefore allowing network access.
Why Must the Network Be Layer 2?
* 802.1X authentication operates at Layer 2 (Data Link Layer) before any IP-based communication (Layer 3) occurs.
* If the authentication device and user terminal were on different Layer 3 networks, the authentication packets (EAPOL - Extensible Authentication Protocol Over LAN)would not be forwarded.
* In the figure, the authentication control point is at theaggregation switch, which means thePC and switch must be in the same Layer 2 domain.
Components of 802.1X Authentication in the Figure:
* Supplicant (PC)# The device requesting network access.
* Authenticator (Aggregation Switch)# The switch controlling access to the network based on authentication results.
* Authentication Server (iMaster NCE-Campus & AD Server)# Verifies user credentials and grants or denies access.
* Layer 2 Connectivity Requirement# ThePC must be in the same Layer 2 networkas the Authenticatorto communicate via EAPOL.
Why "TRUE" is the Correct answer:
* 802.1X authentication is performed before IP addresses are assigned, meaning it can only operate in a Layer 2 network.
* EAPOL (Extensible Authentication Protocol Over LAN) messages are not routableand must stay within a single Layer 2 broadcast domain.
* In enterprise networks,VLAN-based 802.1X authentication is often used, where authenticated users are assigned to a specific VLAN.

* IEEE 802.1X Standard Documentation# Layer 2 Network Authentication
質問 # 41
Which of the following statements is false about the restrictions on configuring bandwidth profiles in parent and child policies on a firewall?
- A. The maximum bandwidth specified in a child policy cannot be greater than that specified in the parent policy.
- B. The connection limit specified in a child policy cannot be smaller than that specified in the parent policy.
- C. The parent and child policies must reference different bandwidth profiles.
- D. Both the parent and child policies must both use the same traffic limiting mode; that is, either "setting the upstream and downstream bandwidths" or "setting the overall bandwidth".
正解：C
解説：
Comprehensive and Detailed Explanation:
* Bandwidth policies use a hierarchical structure(Parent # Child).
* Child policies must follow parent policiesin terms of bandwidth restrictions.
* Why is C false?
* A parent and childcan use the same bandwidth profile.
* The firewall allowsinheritanceof bandwidth settings.
