NEW QUESTION # 36
Which of the following is not a major factor that drives enterprises to migrate to the cloud?
Answer: D
Explanation:
"Overall, the key factors driving enterprise cloud migration fall into three main categories: technological innovation, business requirements, and government incentives." Huawei source: Training PDF p. 6 Technical Deep Dive Huawei explicitly classifies the principal cloud migration drivers into technological innovation, business requirements and government incentives. Option B is therefore a driver because virtualization, distributed computing, cloud-native services, automation, AI and managed infrastructure allow organizations to deploy and change systems more quickly. Option D is also a driver because businesses migrate to reduce infrastructure overhead, accelerate product delivery, support elastic capacity and improve competitiveness.
Option A is likewise named by Huawei. Government incentives include digital-transformation initiatives, regulatory frameworks, national infrastructure programs and policies that encourage adoption of cloud platforms. An executive mandate, option C, is a management authorization or directive rather than one of the curriculum's three fundamental drivers. Senior executives may choose to migrate, but the underlying purpose normally arises from technical, business or policy factors.
For example, an e-commerce company may migrate to Huawei Cloud because promotional peaks require Auto Scaling and ELB. Management signs off on the initiative, but the business driver is elasticity and faster service delivery. A manufacturing enterprise may migrate for access to IoT and AI services; that is an innovation-driven use case. Some exam banks incorrectly exclude government incentives, but Huawei's V3.5 slide explicitly includes them. The evidence supports C alone as the 'not a major factor' answer.
NEW QUESTION # 37
The architecture relies on small functional blocks, each centered on a single responsibility and function. A large, complex application is built as a suite of modular services. Which of the following architectures is described?
Answer: D
Explanation:
"The microservice architecture breaks down applications into groups of small services called 'microservices', which cooperate with each other to provide business capabilities."
"Each service runs as an independent process. Lightweight communication mechanisms (usually based on RESTful APIs) are used between services."
"Each microservice is designed, developed, and tested by an independent team, and can be deployed independently and automatically in the production environment." Huawei source: Training PDF p. 507 Technical Deep Dive The description is of microservice architecture, option D. A microservice solution decomposes a large application into smaller, loosely coupled services, each centered on a distinct business capability. A service runs independently and exposes an API or another lightweight communication interface. Teams can develop, test, deploy and scale individual services without automatically replacing the entire application.
Option A is incorrect because virtualization refers to computing-resource isolation rather than the division of application functionality. Option B is incorrect because monolithic architecture packages interdependent business features into one comparatively tightly coupled deployment unit. Option C , service-oriented architecture (SOA), also uses service boundaries, but usually emphasizes broader enterprise integration and may organize services at larger granularity. Huawei's training specifically describes independently deployable small functional units and language-agnostic APIs as microservice characteristics.
An e-commerce application can be divided into catalog, inventory, authentication, orders and payment services. Each group can deploy updates to its own service and scale according to its demand. This increases agility but introduces distributed-systems concerns: network latency, service discovery, traffic management, observability, API versioning, cross-service authentication, retries and data consistency. Huawei Cloud offers CCE, ServiceStage and Application Service Mesh to support relevant operational capabilities. Architecture selection should account for team maturity and application complexity; microservices are not automatically better for every small system. Nevertheless, the stem matches Huawei's official microservice definition precisely.
NEW QUESTION # 38
Cloud Bastion Host (CBH) is a unified security platform offered by Huawei Cloud. It supports unified asset management, vulnerability detection, baseline checks, single sign-on (SSO), and web page tamper protection.
CBH uses a protocol-based forward proxy and remote-access isolation, and provides a unified O & M login portal for centralized management and O & M audits of cloud resources such as servers, cloud hosts, databases, and application systems.
Answer: B
Explanation:
"Cloud Bastion Host (CBH) is a unified security management and control platform that provides single sign- on (SSO), unified asset management, multi-terminal access protocols, file transfer, and session collaboration for enterprises."
"CBH provides various functional modules, such as department, user, resource, policy, operation, and audit modules." Huawei source: Training PDF p. 349 Technical Deep Dive Huawei Cloud Bastion Host (CBH) is a privileged-access and operations-auditing platform. It provides centralized asset management, single sign-on, identity authentication, access authorization, session control, controlled file transfer and audit records. The question correctly mentions protocol-based forward proxy technology, remote-access isolation and a unified operations login portal, but incorrectly assigns vulnerability detection, baseline checks and web-page tamper protection to CBH. Those capabilities are primarily associated with Huawei Host Security Service and related workload-protection services. Therefore the statement is FALSE, option B.
For example, a production administrator may access an ECS or database through CBH. The platform authenticates the operator, checks permissions and records the session for accountability. Multi-factor authentication and privileged access policies help prevent unauthorized system changes. By contrast, detecting host vulnerabilities and assessing security baselines require workload or security assessment tools.
Web tamper detection and protection also belong to appropriate web or host security controls rather than the bastion host's core role.
A layered enterprise design could use CBH for controlled operational access, IAM for cloud API privileges, HSS for server protection, WAF for application-layer attacks and Cloud Trace Service for auditing cloud operations. No single component should be treated as performing all security functions. Huawei V3.5 specifically lists CBH's account, authorization, authentication and audit capabilities. Since the question merges those with unrelated HSS features, the entire true/false statement is false.
NEW QUESTION # 39
After a company migrates its workloads to the cloud, multiple cloud servers in a virtual private cloud (VPC) need Internet access. However, the EIPs associated with the cloud servers might be attacked. An engineer suggests adding multiple EIPs when configuring DNAT rules. If one EIP is attacked, the other EIPs can continue to provide services and keep operations running normally.
Answer: B
Explanation:
"SNAT translates private IP addresses into EIPs, allowing traffic from a private network to go out to the Internet."
[Related section] DNAT maps an incoming EIP/port to a destination server; multiple EIPs in an SNAT rule are the documented outbound availability option.
Huawei source: Training PDF pp. 169-171; official NAT guidance
Technical Deep Dive
The scenario describes private ECSs requiring outbound Internet access, which is a Source Network Address Translation (SNAT) problem. Huawei NAT gateways can use one or more EIPs in supported SNAT configurations. If a particular public address is blocked or attacked, alternative EIPs may preserve outbound connectivity, subject to service behavior and security controls. DNAT has a different purpose: it maps incoming traffic targeting a public EIP and port to a specified private server and port.
The statement explicitly recommends configuring multiple EIPs in DNAT rules as the documented availability strategy for general outbound access, so it is FALSE. The relevant documented technique is configuring multiple EIPs in SNAT rules. It is important not to infer that attaching more EIPs to DNAT automatically provides seamless inbound service failover. Incoming clients must use an address and port that resolve and route to an available service endpoint, and DNAT port mapping has its own uniqueness constraints.
For Internet-facing applications, robust availability may require ELB, health checks, DNS failover, DDoS protection and redundant backends. For outbound access, NAT gateway EIP pools, route correctness and the limits of the gateway should be monitored. Architects should also assess whether an EIP block is due to anti- DDoS blackholing; multiple EIPs are not a substitute for an appropriate traffic-mitigation service. The question intentionally uses DNAT where SNAT is needed, making B correct.
NEW QUESTION # 40
The Internet of Things (IoT) is a network concept. It involves connecting information-sensing devices to the Internet for intelligent identification, locating, tracking, monitoring, and management. From basic sensor networks to complex system integration, IoT lets devices communicate with one another and exchange data for automated, intelligent control.
Answer: A
Explanation:
"The Internet of Things (IoT) is a network that links diverse sensors and devices through the Internet, enabling smart identification, positioning, tracking, monitoring, and management. It spans basic sensor networks to advanced integrated systems, facilitating device communication and data exchange for automated, intelligent operations." Huawei source: Training PDF p. 664 Technical Deep Dive Huawei's V3.5 curriculum defines the Internet of Things as a network that connects sensors and devices so they can identify, locate, track, monitor and manage real-world objects and exchange data for automated operation. The statement accurately paraphrases that definition and is TRUE, option A.
An IoT architecture can be considered in four functional layers. Sensors and embedded controllers collect measurements at the device layer, such as temperature, pressure, motion or vibration. Network services carry messages over Ethernet, Wi-Fi, cellular connectivity, 5G or NB-IoT. An IoT platform authenticates and manages devices, receives telemetry, forwards data and exposes APIs. Business applications analyze measurements, display dashboards and issue supported remote-control commands.
Huawei Cloud IoTDA is an example of a managed platform used for registering and communicating with physical devices. Protocols may include MQTT, HTTPS and LwM2M over CoAP, depending on device capabilities. Consider an industrial sensor reporting temperature through MQTT: a cloud application can compare its readings with operational thresholds, alert engineers and instruct an appropriate actuator. For scenarios with strict latency, limited bandwidth or intermittent connectivity, local IoT Edge processing can operate before sending summarized data to the cloud. Secure IoT requires strong device identities, credential management, encryption, firmware updates and appropriate authorization. The user's description of intelligent identification, monitoring and automated control matches the official course.
