최신 Huawei Certified ICT Expert H12-891_V1.0 무료샘플문제 (Q251-Q256):

질문 # 251
Man-in-the-middle attacks (MITM) or IP/MAC Spoofing attacks are common on intranets and can cause information leakage.
Which configuration method can prevent these attacks?

A. Limit the maximum number of MAC addresses that can be learned on a switch interface.
B. Configure the trusted or untrusted interface.
C. Configure DHCP snooping to check the CHADDR field carried in a DHCP Request packet.
D. Configure association between DHCP snooping and IPSG or DAI on the switch.

정답：D

설명：
Comprehensive and Detailed
✔ The Best Protection Against MITM and Spoofing Attacks:
✅ (D) Associating DHCP Snooping with IPSG (IP Source Guard) and DAI (Dynamic ARP Inspection) provides complete protection by:
Blocking rogue DHCP servers.
Preventing MAC/IP spoofing.
Ensuring only valid clients access the network.
✔ Why Not Other Options?
❌ (A) Configuring trusted/untrusted interfaces only helps block rogue DHCP servers, but does not prevent spoofing.
❌ (B) Limiting MAC address learning prevents MAC flooding, but does not stop MITM attacks.
❌ (C) Checking the CHADDR field in DHCP Snooping helps detect spoofed requests, but does not block all MITM scenarios.

질문 # 252
In the Huawei SD-WAN Solution, which of the following routing protocols is used to advertise VPN routes between CPEs?

A. BGP
B. OSPF
C. RIP
D. IS-IS

정답：A

설명：
BGP in Huawei SD-WAN
Huawei SD-WAN uses BGP (Border Gateway Protocol) as the primary routing protocol to exchange VPN routes between Customer Premises Equipment (CPEs) and the controller.
✅ Why BGP is Used in SD-WAN?
Scalability: BGP can handle a large number of VPN routes.
Policy-Based Routing: BGP allows traffic engineering and policy control across SD-WAN tunnels.
Multiprotocol Support: Huawei SD-WAN uses MP-BGP to exchange IPv4, IPv6, and VPNv4 routes.

질문 # 253
Which of the following are carried in an HTTP/1.1 response?

A. Status line
B. Response header
C. Empty line
D. Response body

정답：A,B,C,D

설명：
Understanding HTTP/1.1 Response Structure
# What is an HTTP Response?
* The response is sent from the server to the client after processing an HTTP request.
* The structure follows a standardized format:
Elements of an HTTP/1.1 Response:
# A. Status Line # Contains protocol version, status code, and reason phrase.# B. Response Body # Contains HTML, JSON, XML, or other content.# C. Response Header # Provides metadata about the response (e.g., Content-Type, Server).# D. Empty Line # A blank line separates headers from the response body.
Example of an HTTP/1.1 Response:
HTTP/1.1 200 OK
Date: Sat, 08 Mar 2025 14:00:00 GMT
Server: Apache/2.4.41 (Ubuntu)
Content-Type: text/html; charset=UTF-8
<html>
<body>
<h1>Welcome to Huawei Datacom</h1>
</body>
</html>
Why is the Answer A, B, C, D?
# An HTTP response includes a status line, headers, an empty line, and a response body.
Real-World Application:
* Web Application Debugging: Helps developers analyze server responses.
* API Security: Validates response headers to prevent injection attacks.
# Reference: Huawei HCIE-Datacom Guide - HTTP Protocol and Response Headers

질문 # 254
Which of the following technologies can be used to isolate users in the same VLAN?

A. Ethernet port security
B. Super VLAN
C. Port isolation
D. IPSG

정답：A,C,D

설명：
Understanding User Isolation in the Same VLAN
In a traditional VLAN, all devices within the same VLAN can communicate unless additional security policies are applied. To isolate users within the same VLAN, the following technologies can be used:
✅ B. Port Isolation (Private VLAN or Layer 2 Isolation)
Prevents communication between ports within the same VLAN.
Common in enterprise and campus networks to improve security.
Example: Isolating guest users from employees within the same VLAN.
✅ C. IPSG (IP Source Guard)
Blocks IP address spoofing within the same VLAN.
Uses DHCP snooping binding table to verify whether a device is using an authorized IP address.
✅ D. Ethernet Port Security
Limits the number of MAC addresses allowed per port.
Prevents unauthorized devices from communicating within the VLAN.
❌ A. Super VLAN (Incorrect Choice)
Super VLAN groups multiple VLANs under a single Layer 3 gateway, but it does not provide isolation within the same VLAN.
Real-World Application:
Public Wi-Fi Networks: Ensures that users within the same VLAN cannot communicate with each other.
Enterprise Security: Prevents unauthorized access or attacks within shared VLANs.
✅ Reference: Huawei HCIE-Datacom Guide - VLAN Security and User Isolation Technologies
