질문 # 17
Which of the following can be prevented by using the unauthorized access prevention function of Huawei switches?
정답：B,C
설명：
Huawei switches' unauthorized access prevention function can prevent users from connecting unauthorized hubs and sharing network access through unauthorized Wi-Fi hotspots. An unauthorized hub allows multiple terminals to enter the network through a port intended for a single managed endpoint. This can bypass normal terminal-count limitations, admission controls, and access-policy enforcement.
Unauthorized Wi-Fi hotspot sharing occurs when a user connects an authenticated endpoint to the enterprise network and then enables hotspot or connection-sharing functionality. Other terminals can subsequently access the network through that endpoint without completing the required authentication process. Huawei switches can analyze terminal behavior, MAC-address relationships, packet characteristics, and access patterns to identify and restrict this behavior.
A USB flash drive is a local storage device and does not provide Ethernet network access, so option A is unrelated to switch-based unauthorized network access prevention. An unauthorized router is normally controlled through device identification, NAC, port security, or explicit access policies rather than the specific hub and hotspot-sharing prevention function described by this question.
Huawei intelligent terminal management combines terminal identification, authorization, traffic analysis, and bogus-terminal detection to achieve visualized access and prevent unauthorized connectivity.
질문 # 18
Which of the following statements is false?
정답：A
설명：
Option C is false. Traditional QoS can classify traffic and provide differentiated treatment for service categories such as voice, video, and ordinary data. It normally performs classification, marking, policing, shaping, congestion avoidance, and queue scheduling on an interface. This provides service-level differentiation but does not deliver sufficiently refined simultaneous management across multiple users and multiple applications.
Huawei's material explicitly states that traditional QoS schedules traffic based on port bandwidth and can differentiate traffic according to service levels, but it is difficult to distinguish traffic by user. It also states that traditional QoS cannot manage and schedule traffic from multiple services and multiple users simultaneously.
HQoS addresses this limitation through hierarchical, multi-level queues. For example, a parent level can allocate bandwidth to departments, VPNs, sites, or users, while child queues prioritize applications such as voice, video, email, and best-effort traffic. Huawei describes HQoS as hierarchical scheduling that differentiates both services and users. Therefore, statements A, B, and D are correct, while statement C incorrectly attributes an HQoS capability to traditional QoS.
질문 # 19
A label stack is an ordered set of labels. MPLS supports a maximum of three layers of nested labels.
정답：B
설명：
The statement is false. An MPLS label stack is an ordered sequence of label-stack entries, with the top label processed first and the bottom identified by the Bottom-of-Stack bit. However, the MPLS architecture does not define a universal maximum of three nested labels. An MPLS forwarding operation may replace the top label, remove it, or push one or more additional labels onto the stack.
Practical label depth is constrained by device implementation, forwarding ASIC capabilities, packet size, and the number of network functions being encoded. A conventional MPLS VPN may use two labels: a transport label and a VPN label. More advanced deployments can add labels for traffic engineering, segment routing, entropy, service chaining, or hierarchical transport. This can produce stacks deeper than three entries.
Therefore, "three layers" may describe a limitation of a particular platform, software version, or deployment design, but it is not an MPLS protocol maximum. RFC 3032 defines the stack as a sequence of four-byte entries and explicitly allows one or more entries to be pushed without specifying a three-label ceiling.
질문 # 20
Which of the following statements is true about MACsec?
정답：B
설명：
Hardware-based encryption is the unambiguously correct statement. MACsec protects Ethernet frames at Layer 2 using AES-GCM-based authenticated encryption. On enterprise switches and routers, the encryption and integrity operations are commonly implemented in forwarding ASICs or dedicated hardware so that frames can be protected at high throughput with low latency.
Option A is incorrect because complex manual configuration is not an inherent requirement. MACsec can use manually configured connectivity-association keys, but IEEE 802.1X MACsec Key Agreement can automate peer authentication, secure-channel establishment, key distribution, and rekeying. The operational complexity therefore depends on the deployment model and management platform.
Option C is also inaccurate. MACsec is media-independent, meaning it can operate over supported copper or fiber Ethernet; however, it does not eliminate the requirement for appropriate Layer 2 connectivity between participating MACsec entities. Standard hop-by-hop MACsec protects Ethernet links or LAN connectivity between peers and is not a general Layer 3 tunneling mechanism.
MACsec supplies Layer 2 confidentiality, integrity, origin authentication, and replay protection. Its encryption can be performed directly in network-device hardware, enabling substantially better forwarding performance than software-only encryption implementations.
질문 # 21
Which of the following models supports IPS, antivirus, and URL filtering at the same time?
정답：C
설명：
The AR5710-SE is the security-enhanced model that supports intrusion prevention, antivirus, and URL filtering concurrently. The "SE" variant is designed for branch scenarios requiring integrated routing and advanced security processing instead of only basic WAN connectivity and packet forwarding.
IPS examines network traffic for attack signatures and abnormal behavior and can block detected intrusions.
Antivirus inspection identifies malicious files or content using security-signature databases. URL filtering controls access to websites based on categories, reputation, or explicitly configured allowlists and blocklists.
Supporting all three functions simultaneously allows the AR5710-SE to operate as both an SD-WAN CPE and a secure branch egress gateway, reducing the requirement for an additional branch firewall.
Huawei's SD-WAN security architecture identifies firewall protection, antivirus, IPS, and URL filtering as its principal service-traffic security functions. Huawei also recommends advanced security functions such as URL filtering, IPS, and antivirus for branch scenarios requiring stronger Internet-egress protection. Among the listed models, the AR5710-SE provides the combined feature set. Therefore, option A is correct.
