NEW QUESTION # 54
The CNN-based application identification technology can identify both known and unknown applications.
Answer: A
Explanation:
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.
NEW QUESTION # 55
What are the objectives of the next-generation advanced industrial network with an open architecture?
Answer: A,B,C,D
Explanation:
All four options represent objectives of a next-generation advanced industrial network. IP-based connections establish a standardized communications foundation, allowing production systems, controllers, sensors, machines, and management platforms to communicate through scalable Ethernet and IP technologies instead of isolated proprietary field networks.
Networked devices extend connectivity across operational technology assets so that equipment status, production data, and control information can be shared across production lines, plants, data centers, and cloud platforms. Network intelligence introduces automated provisioning, telemetry, analytics, fault prediction, policy optimization, and closed-loop operations. These capabilities reduce manual configuration and improve production availability.
Network-security integration is equally essential because greater openness and interconnection increase the potential attack surface. Security must therefore be integrated into access control, segmentation, device identification, encrypted communication, anomaly detection, and policy enforcement rather than added as an isolated external system. Huawei's broader CloudCampus architecture similarly emphasizes automated provisioning, intelligent O & M, secure interconnection, integrated wired and wireless management, and open network capabilities. The four objectives collectively create an open, connected, intelligent, and secure industrial communications architecture.
NEW QUESTION # 56
Which of the following statements is true about MACsec?
Answer: B
Explanation:
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.
NEW QUESTION # 57
What are the two IPsec data encapsulation modes?
Answer: B,C
Explanation:
The two IPsec encapsulation modes are transport mode and tunnel mode. In transport mode, IPsec protects the upper-layer payload of the original IP packet while retaining the original IP header as the packet's outer header. It is commonly associated with end-to-end host communication, although it can also protect a GRE packet between tunnel endpoints.
In tunnel mode, IPsec protects the complete original IP packet and adds a new outer IP header containing the addresses of the IPsec peers. This mode is commonly used between security gateways, routers, or site-to-site VPN endpoints because the original source and destination information can be protected within the encrypted inner packet. RFC 4301 formally defines transport and tunnel as the two IPsec security-association modes.
AH and ESP are not encapsulation modes. They are IPsec security protocols. Authentication Header provides integrity and source authentication but not encryption. Encapsulating Security Payload can provide encryption, integrity, authentication, and anti-replay protection. Either protocol can conceptually operate in transport or tunnel mode, although ESP is overwhelmingly used for encrypted enterprise VPN and SD-WAN data channels.
NEW QUESTION # 58
What is the function of the PROFINET DCP?
Answer: A
Explanation:
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.
