The correct answer is A (TRUE) . Huawei Cloud Stack compute resource management documentation explicitly describes the behavior of soft-affinity , which is the practical equivalent of weak affinity in scheduling policy terms. Huawei states that if host resources are sufficient, VMs in the same soft-affinity group will be scheduled to the same host . It further states that if resources are insufficient or the current host is faulty, the VMs can be scheduled to different hosts . This matches the wording of the question almost exactly.

Huawei ECS group documentation also explains that an ECS group can be configured with affinity, anti-affinity, weak affinity, or weak anti-affinity policies, which confirms that weak affinity is an officially recognized scheduling policy in Huawei Cloud Stack. The “weak” part means the scheduler prefers a placement rule but is allowed to violate it when necessary to ensure successful deployment or continuity.

Therefore, the statement accurately reflects Huawei’s documented scheduling behavior: under normal conditions, VMs tend to be placed together, but if resources are inadequate, the rule may be broken. So the verified answer is TRUE .

The correct answer is C. Tenant application response time . Huawei’s comprehensive monitoring documentation states that service monitoring tests the health of the current application and locates application exceptions based on monitoring metrics such as response time and availability . That directly matches the scenario of monitoring tenant application response time .

The other options belong to different monitoring domains. Health status of the physical server power supply is hardware or infrastructure monitoring, not service monitoring. Virtual network congestion is a network-layer performance issue rather than an application service-monitoring scenario. Latency of the distributed tracing system is closer to tracing or APM platform internals than to the application service-monitoring scenario explicitly described in Huawei’s cited service-monitoring definition. Huawei’s wording focuses on the monitored application’s health, response time, and availability, not hardware power modules or tracing-platform latency.

Therefore, based on Huawei’s official description of comprehensive service monitoring , the scenario clearly covered is tenant application response time , making the verified answer C .

Horizon is the web-based dashboard for OpenStack, designed to provide a consistent graphical interface for managing cloud resources. In practice, Horizon focuses on presenting a consistent view of services to users and administrators, and OpenStack components commonly maintain API backward compatibility to support upgrades and continued interoperability. OpenStack documentation also shows that Horizon can be used in larger and multi-region environments, which supports the idea that scalability is relevant to its operational value.

However, API eventual consistency is not a Horizon value proposition. “Eventual consistency” is a concept found in distributed storage systems such as OpenStack Swift/Object Storage, where updates may take time to become visible everywhere. OpenStack documentation explicitly uses this term in the context of Object Storage behavior, not Horizon dashboard design. Because Horizon is a management dashboard rather than a distributed storage consistency model, API eventual consistency does not belong as one of its core value propositions. Therefore, the correct answer is A . This is the best-supported conclusion from official OpenStack documentation and aligns with Huawei Cloud training-style OpenStack topic coverage.

The correct answer is B. L3 Agent . Official OpenStack Neutron documentation states that routers provide virtual Layer 3 services such as routing and NAT , and that the Networking service uses a layer-3 agent to manage routers. OpenStack also explicitly says that the neutron-l3-agent uses the Linux IP stack and iptables to perform L3 forwarding and NAT . This directly matches the wording of the question.

The other options do not fit. The L2 agent handles local virtual switch configuration and Layer 2 networking behavior, not routing and NAT. The DHCP agent provides DHCP services to tenant networks. “ NAT Agent ” is not the standard Neutron component name used in official OpenStack architecture. OpenStack documentation consistently identifies the L3 agent as the component responsible for router namespace management, forwarding, floating IP behavior, and source NAT functions.

This is also consistent with Huawei Cloud Stack networking architecture topics, where routing and NAT functions are tied to Neutron Layer 3 services. Therefore, the fully verified answer is B. L3 Agent .

The correct answer is B (FALSE) . Huawei documentation supports the first part of the statement: Combined API is described as providing the service backend for services such as ECS, BMS, IMS, and EVS , and Huawei usage materials show console requests being forwarded through the UI to Combined API for backend processing. That means it does function as a backend service layer between the console and underlying cloud services.

However, the statement becomes incorrect when it says Combined API must be deployed in the Global zone . Huawei architecture documentation explains that Huawei Cloud Stack includes both a global zone and regional deployment structure , and not all components belong to the global zone. Huawei snippets describing global-region deployment list typical global-zone components such as ManageOne and the cloud service console , while Combined API is described separately as a service backend in the broader architecture of the region/global deployment model. This supports the conclusion that Combined API is not simply a mandatory global-zone-only component .

So the backend-function part is true, but the deployment claim is not. Therefore, the overall statement is FALSE .

The correct answer is D . Huawei’s official HUAWEI CLOUD Stack NAT Gateway documentation explains that DNAT is used to map the private IP address and port of a cloud server in a VPC to a public IP address and port by binding an EIP. In practical terms, DNAT allows requests that arrive at a public IP address to be forwarded to the private IP address of a server inside the cloud network. That matches option D exactly.

Option A describes SNAT , not DNAT. Huawei explicitly states that SNAT translates a private IP address into an extranet/public IP address so cloud servers can access the Internet. Option B is also related to SNAT behavior, because Huawei notes that multiple cloud servers in a VPC can share an EIP for outbound Internet access through SNAT. Option C describes a filtering or firewall-style function rather than NAT translation.

Therefore, in Huawei Cloud Stack networking, DNAT is specifically used for inbound mapping from public addresses to private cloud-server addresses , so the verified answer is D .

The correct fill-in answer is hosts. Huawei documentation explicitly states that memory overcommitment must be enabled on the node where the VM is deployed before the VM can use that capability. In Huawei Cloud Stack usage and O & M materials, the node here is the compute host, and the docs also describe memory overcommitment behavior in terms of host resources and overcommitment ratios.

Huawei O & M guidance further explains that host resource isolation must be enabled before memory overcommitment is enabled, which confirms that this setting is tied to the compute-host layer. Some Huawei documents also refer to enabling or disabling memory overcommitment for a host group, but the actual execution point is still the underlying hosts/nodes in that group. Because your fill-in statement says “enable memory overcommitment on _____,” the most accurate and broadly supported answer is hosts. Therefore, after correcting the sentence, the verified answer is hosts.

The best verified answer is D. Workspace . Huawei’s official health-check documentation for FusionCare shows that FusionCare supports unified health checks for multiple Huawei Cloud Stack components and services. The published health-check item lists explicitly include Service OM , eSight , and CCE and SWR , which confirms that those services are within FusionCare’s supported inspection scope.

By contrast, the Huawei monitoring materials mention Workspace Overview under broader monitoring capabilities, not under the FusionCare-supported health-check list shown in the cited documents. In other words, Workspace appears in Huawei’s overall monitoring ecosystem, but it is not evidenced in the cited FusionCare support list the way Service OM, eSight, and CCE are. That makes Workspace the option that cannot be checked using FusionCare in this question set.

So based on Huawei’s documented FusionCare-supported inspection items, A , B , and C are covered, while D is not shown as a FusionCare check target. Therefore, the verified answer is D .
