Which of the following protocol data packets can be encapsulated in a VPN using GRE?
Antwort: A,B,C,D
Begründung:
GRE is a multiprotocol encapsulation mechanism and can carry all the listed packet types. It inserts a GRE header around the original payload and then places the resulting GRE packet inside a delivery-protocol packet. Because the GRE header contains a Protocol Type field identifying the encapsulated payload, GRE is not restricted to ordinary IPv4 unicast traffic.
IPv6 packets can be transported as GRE payloads when supported by the tunnel endpoints. IP unicast traffic is the most common use case. GRE can also carry IP multicast and broadcast packets, which is one of its major advantages over basic IPsec tunnel selectors that traditionally focus on IP unicast traffic. This enables routing protocols, multicast applications, discovery traffic, and other non-unicast services to operate across a logical point-to-point tunnel.
RFC 2784 defines GRE as a general mechanism for encapsulating an arbitrary network-layer protocol over another network-layer protocol. It also defines the Protocol Type field used to identify the carried payload.
Huawei uses GRE as an SD-WAN overlay data-channel option and can additionally secure it using IPsec when confidentiality and integrity are required.
32. Frage
What is the function of the PROFINET DCP?
Antwort: D
Begründung:
PROFINET DCP, meaning Discovery and Basic Configuration Protocol, is used during device discovery and initial network configuration. It operates at the data-link layer and enables an engineering station or PROFINET IO controller to locate devices on the local Ethernet segment, identify them by MAC address or station name, assign a PROFINET device name, and configure IP parameters such as the IP address, subnet mask, and default gateway.
DCP is therefore not responsible for normal cyclic process-data exchange. Real-time PROFINET communication performs that function after the controller and I/O device have been configured and an application relationship has been established. Alarm exchange and acyclic parameterization are also handled through other PROFINET communication relationships and services.
The distinction matters during commissioning. A new I/O device may initially have no usable IP configuration. DCP allows the controller or engineering tool to discover it at Layer 2 and provision the identity and addressing information required before higher-layer communication can begin. PROFINET documentation identifies DCP as mandatory for assigning IP addresses and configuring station names on the local network.
33. Frage
Which of the following functions is supported by the AR6177?
Antwort: B
Begründung:
The distinguishing function supported by the AR6177 is VDSL. VDSL, or Very-high-bit-rate Digital Subscriber Line, enables a branch router to obtain WAN connectivity over existing copper telephone infrastructure. It is appropriate for small branches and distributed sites where Ethernet private lines, fiber, or mobile connections are unavailable or commercially impractical.
The AR6177 can terminate the VDSL access circuit and provide routing, NAT, DHCP, VPN, and other branch-gateway functions for the connected LAN. In this single-answer question, Wi-Fi and PoE are not the defining integrated capabilities of the AR6177 model. Similarly, the complete combination of IPS, antivirus, and URL filtering belongs to a security-enhanced product profile rather than the function used to distinguish the AR6177.
Huawei's campus design material recognizes DSL links as a specific WAN-access category and notes that deployments involving complex or low-speed links, including DSL, may require an appropriate branch-device deployment method. The model is therefore selected when direct VDSL-based WAN access is required.
Consequently, VDSL is the supported capability intended by this question, and option C is correct.
34. Frage
Which of the following can be prevented by using the unauthorized access prevention function of Huawei switches?
Antwort: A,D
Begründung:
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.
35. Frage
The CNN-based application identification technology can identify both known and unknown applications.
Antwort: A
Begründung:
The statement is true in the context of Huawei's AI-assisted application-identification architecture.
Conventional identification depends mainly on predefined signatures, fixed destination addresses, port numbers, protocol fields, DNS correlation, or deep packet inspection. Huawei's standard SD-WAN process uses Service Awareness and First-Packet Identification signature databases to identify and group application traffic. These mechanisms are effective for known applications but become less reliable when traffic is encrypted, applications change versions, or previously unseen applications appear.
A CNN-based classifier learns multidimensional traffic characteristics such as packet-length sequences, timing, direction, and flow behavior. It can classify traffic matching learned application patterns and, when implemented with open-set detection, recognize flows outside known classes as unknown or zero-day applications. Commercial-grade deep-learning traffic classification research demonstrates identification of known encrypted applications together with the handling of unknown zero-day applications.
This does not mean the system automatically assigns an exact commercial name to every unseen application.
It detects that the traffic does not match established classes so that it can be investigated, labelled, and incorporated into later model updates. Therefore, the statement is True.
