22. Frage
In architecture design, security generally means the capacity of a product or service to remain operational or executable under specified conditions and for a defined period. This attribute reflects both the product's availability and maintainability.
Antwort: B
Begründung:
"Availability: The probability that a product or service remains operational or usable at any given time."
[Supporting material] Availability combines reliability and maintainability, and is distinct from the security design principle.
Huawei source: Training PDF p. 16
Technical Deep Dive
The statement is false because it substitutes the security concept for the availability concept. Availability measures the probability that a service is usable or operational when required, and its design is influenced by reliability, maintainability, redundancy and recovery capabilities. Security, by contrast, concerns protecting systems, information and infrastructure against unauthorized access, disclosure, modification and disruption.
Huawei's architecture design principles distinguish security and availability as separate concerns. An RDS primary/standby deployment can improve availability by enabling failover, but database security still requires authentication, least-privilege access, network restrictions, auditing and encryption. Similarly, Elastic Load Balance may improve resilience by distributing traffic among healthy backend ECSs; that does not independently protect an application from SQL injection or credential theft. Separate controls such as WAF, HSS, IAM and data encryption address those risks.
Availability can be assessed using SLA targets or quantitative measures such as mean time between failures and mean time to repair. Security controls can also influence availability-for example, DDoS mitigation protects service reachability-but the definitions are not interchangeable. Because the question describes remaining operational under specified conditions, it characterizes availability rather than security. The original word 'security' should remain in the false examination statement; silently correcting it would change the assessed answer.
23. Frage
A company plans to use a Virtual Private Network (VPN) to enable communication between its on-premises data center and multiple VPCs on Huawei Cloud. Which statement about VPN is false?
Antwort: B
Begründung:
"S2C VPN involves three key components: VPN gateway, customer gateway, and VPN connection."
[Supporting content] Site-to-Cloud VPN uses IKE and IPsec; Point-to-Cloud VPN provides SSL-based remote access. For same-region VPC access, VPC peering or equivalent private routing is used.
Huawei source: Training PDF pp. 139-140; official VPN/VPC guidance
Technical Deep Dive
Huawei V3.5 describes Site-to-Cloud VPN as a secure communication mechanism involving a VPN gateway, customer gateway and VPN connection. IKE negotiates security parameters and IPsec protects traffic, supporting the claim in A. B correctly identifies the major Site-to-Cloud VPN components. C correctly differentiates Site-to-Cloud IPsec VPN from Point-to-Cloud SSL-based access in the curriculum.
Option D is the false statement for the architecture described. For VPCs in the same Huawei Cloud region, direct private connectivity through VPC peering or other supported routing mechanisms is recommended rather than setting up the posited VPN gateway-to-gateway link. VPN is used for scenarios involving encrypted connectivity between on-premises networks and cloud VPCs or appropriate cross-region environments.
For an enterprise that wants a single on-premises data center to reach several VPCs, the architect must decide whether to use Site-to-Cloud VPN, Direct Connect, Cloud Connect and/or an Enterprise Router based on latency, bandwidth, cost and redundancy requirements. After establishing a tunnel, verify the IKE phase, IPsec security associations, route tables, encryption-domain selectors, customer gateway configuration, network ACLs and security groups. A healthy tunnel does not guarantee application reachability if address ranges overlap or routes are missing. These caveats do not change the intended single false answer, D.
24. Frage
Cloud Container Engine (CCE) provides multiple Service network access modes. Match each description with its corresponding access mode.
Antwort:
Begründung:
Explanation:
"ClusterIP: This is the default type. A virtual IP address that can be accessed only within the cluster is allocated from the Service CIDR block of the cluster."
"NodePort: The Service is exposed on each node's IP address at a static port."
"LoadBalancer: This type of Service adds an external load balancer on the top of a NodePort Service."
"DNAT: This type of Service translates IP addresses for cluster nodes and enables multiple nodes to share an EIP." Huawei source: Training PDF pp. 458-459 Technical Deep Dive This matching exercise tests four Huawei CCE network access modes. The first description is ClusterIP, option A: Kubernetes creates an internal virtual address from the Service CIDR range, normally usable only inside the cluster. The second is NodePort, option B: the Service is exposed on a static port of each node, allowing the relevant node address and port to reach the workload. NodePort traffic normally reaches a corresponding ClusterIP abstraction.
The third description is LoadBalancer, option C. An external load-balancing resource accepts traffic and distributes it to eligible pods; Huawei Cloud ELB supports Layer 4 and, through applicable listener implementations, Layer 7 traffic distribution. The fourth description is Huawei CCE's DNAT mode, option D.
It uses network address translation to allow multiple cluster nodes to share an EIP and avoids tying the externally exposed service to a single node's directly bound EIP.
A Kubernetes Service provides a stable access mechanism even though backend pods may be scheduled, replaced or rescaled. Engineers can inspect configured Services with kubectl get services, check policy and endpoints with kubectl describe service, and verify corresponding EndpointSlices. ClusterIP, NodePort and LoadBalancer are standard Kubernetes Service types. Huawei's DNAT access mode is specific to the CCE service integration and should not be represented as an upstream Kubernetes Service.spec.type value. The original screenshot is retained with empty match boxes; the verified order is A, B, C, D.

25. Frage
Database Security Service (DBSS) offers database auditing, database encryption and access control, and database O & M capabilities. It records database user access in real time, produces fine-grained reports, and issues real-time alerts when attacks or risky operations are detected.
Antwort: B
Begründung:
"DBSS provides database audit, database encryption and access control, and database O & M functions. It records user access to the database in real time, generates fine-grained audit reports, and sends real-time alarms for risky operations and attack behaviors."
"DBSS provides the database audit function in out-of-path mode, which consumes very little database performance." Huawei source: Training PDF pp. 378-379 Technical Deep Dive The statement closely reproduces the Huawei V3.5 Database Security Service (DBSS) definition, so it is TRUE, option A. DBSS provides database auditing, encryption and access-control-related capabilities and database O & M functions. It can record activity involving database users, produce fine-grained reports and alert administrators about suspicious or risky operations.
A central capability is database activity auditing. For example, an account unexpectedly executing a large series of SELECT statements against a customer-information table can be recorded for incident investigation.
Database audit reports help correlate actions with users and sessions, support compliance review and identify unusual access patterns. Huawei's material describes an out-of-path auditing mode, intended to minimize the performance impact on ordinary database requests. It also identifies SQL-injection detection and operational risk alarms.
Audit functions must be distinguished from active prevention. An out-of-path collector primarily observes activity; database privileges, authentication, approved operational workflows and encryption require their own correct design. When an encryption gateway or other in-path protection mode is deployed, the traffic-handling architecture and failure characteristics differ. DBSS can complement IAM, HSS, WAF and Cloud Trace Service, but none replaces a carefully secured database engine. Architects should define audit coverage, retention, tamper protection, access to audit records, alert routing and acceptable performance overhead. The exact source statement includes the same real-time access recording and fine-grained reporting features, making A the correct exam answer.
26. Frage
What does Cloud Eye alerting for monitoring metrics allow you to do?
Select all that apply.
Antwort: A,B,C
Begründung:
"Users can create alarm rules for key metrics of cloud services. When the conditions in the alarm rule are met, Cloud Eye reports the alarms using emails, SMS, or HTTP/HTTPS requests, enabling users to quickly respond to resource changes."
[The slide lists] flexible policies, varied notifications through HTTP/HTTPS/FunctionGraph/SMS/email, Auto Scaling integration, and default or custom alarm templates.
Huawei source: Training PDF p. 591; official Cloud Eye documentation
Technical Deep Dive
Cloud Eye alarm management allows administrators to define resource- and metric-specific thresholds, triggering rules, notification routes and operational responses. Option A is true because alarm policies can be tailored to individual monitored objects, metrics and events. Option B is true because Huawei supplies standard and customizable templates that can be applied across resources in batches, reducing repetitive configuration and improving policy consistency.
Option D is true. The Huawei V3.5 alarm slide lists HTTP/HTTPS, SMS, email, FunctionGraph and Auto Scaling integration, while related official documentation confirms voice notification channels where supported. A Cloud Eye threshold can notify an operator, invoke an automated function or participate in a scaling policy. For instance, sustained CPU utilization above an agreed threshold can initiate capacity scaling while the operations team receives an alert.
Option C is false because Huawei supports monitoring integration with external observability systems. Cloud Eye metrics can be exposed through suitable exporter and API mechanisms to Prometheus-compatible environments, and those metrics can be visualized in Grafana as part of a broader monitoring architecture.
The claim that such interconnection is categorically unsupported is therefore wrong. Operationally, alarm thresholds must account for duration, evaluation periods, retry behavior, resource scale and alert fatigue. Too- sensitive alerts can generate noise, while overly broad thresholds can miss failures. Automatic scaling requires sensible minimum and maximum capacities, cooldown settings and health checks. A, B and D are the supported capabilities; C is the inaccurate denial of integration.
