Emerging Technology

Feature / Application Scenario

Edge computing

The number of street lamps continues to increase, and these street lamps hold billions of cameras and environment sensors, which generate frequent and heavy data for processing, analysis, and storage.

Blockchain

Transparent rules, automatic settlement, and E2E tracking of goods all the way from production to final acceptance make the supply chain trustworthy. Electronic proof of delivery (PoDs) reduces paperwork delays. Smart contracts enable automatic settlement to improve efficiency.

Cloud native

Organizations or enterprises build and run scalable applications in public, private, and hybrid clouds.

According to the Huawei HCIA-Cloud Computing curriculum, emerging technologies like Edge Computing, Blockchain, and Cloud Native are reshaping modern IT infrastructures to handle data more efficiently and securely. In the context ofEdge Computing, the massive proliferation of IoT devices in smart cities—such as billions of cameras and environmental sensors mounted on street lamps—creates a data influx that traditional centralized clouds cannot process in real time without significant latency. Edge computing solves this by moving processing and storage capabilities physically closer to the data sources, allowing for nearly instantaneous response times for critical urban systems like traffic management and public surveillance.

Blockchaintechnology provides a decentralized, distributed ledger that is transformative for global supply chain management. By creating a "single source of truth" that is transparent and immutable, it enables end-to-end (E2E) tracking of goods from production to the final consumer. A core feature is the use ofsmart contracts, which are automated, self-executing rules that trigger settlements and payments immediately upon meeting conditions like electronic proof of delivery (PoD), thereby eliminating intermediaries and reducing paperwork delays.

Finally,Cloud Nativerepresents an architectural approach designed to fully exploit the cloud computing model. The official definition from the Cloud Native Computing Foundation (CNCF) states that these technologies "empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds". By utilizing independent microservices and portable containers, cloud-native applications achieve the high availability, elasticity, and rapid deployment speed required to meet evolving business needs across diverse infrastructure types.

FusionAccess OA security architecture adoptszone-based isolation(red, yellow, green zones).

Each zone islogically and physically isolated

Each zone has itsown FusionAccess system

Data is not allowed to flow freely between zones

OptionBis false because it incorrectly states that data can be transmitted between zones. The other statements correctly reflect FusionAccess OA security and integration characteristics.

In the Huawei FusionCompute environment, storage multipathing is a critical feature used to ensure the continuity of I/O operations and to enhance performance through load balancing. According to the official training materials, statement C is the correct technical recommendation. Multipathing technology, such as Huawei UltraPath, is designed to manage multiple physical paths between a host and a single storage device.

The core requirement for a resilient storage network is the elimination of single points of failure (SPOF). To achieve this, a storage device is configured with at least two controllers (Controller A and Controller B). The best practice for multipathing is to connect the host to network ports ondifferent controllersand allocate these ports to thesame VLAN(the storage plane). This configuration ensures that if one controller fails or is undergoing maintenance, the multipathing software on the host can automatically failover the I/O traffic to the other controller without interrupting the Virtual Machines (VMs).

By placing these ports in the same VLAN, the host can discover all available "targets" (LUNs) through multiple paths. The system can then distribute the I/O load across these paths (Load Balancing) or simply keep one as a standby (Failover). If an administrator were to use ports on the same controller (as suggested in option B), they would still be vulnerable to a total controller failure. Furthermore, multipathing logic is applied per-storage-device to ensure that the block-level mapping remains consistent. In Huawei's FusionCompute, correctly configuring the storage plane with cross-controller redundancy is a prerequisite for high-performance features and overall system stability.

====================

In the official Huawei HCIA-Cloud Computing curriculum, specifically the "Virtualization Basics" module, the characteristics of virtualized hardware are clearly defined. Statement D is FALSE because a Virtual Machine (VM) is not limited to a single virtual network interface card (vNIC). In fact, for many enterprise scenarios, a VM must have multiple vNICs. For example, a VM acting as a software firewall or a multi-homed server would require separate vNICs to connect to different logical networks (such as a Management network, a Service network, and a Backup network). Huawei FusionCompute supports the addition of multiple vNICs to a single VM, each capable of being assigned to a different port group or VLAN.

The other statements are correct based on Huawei’s technical standards. Statement A is true; every vNIC is assigned a globally uniqueMAC address(usually from a prefix reserved for Huawei virtualization) to ensure that Layer 2 switching functions correctly within the DVS. Statement B is true; just like a physical machine, each vNIC can be assigned a uniqueIP addressthrough static configuration or DHCP to allow for Layer 3 communication. Statement C is also accurate; from the perspective of the Guest Operating System, the vNIC behaves exactly like a physical PCI-E network card. It has a driver, it can be configured with MTU settings, and it can transmit and receive frames. The hypervisor (CNA) is responsible for intercepting the data from this "logical" NIC and forwarding it through the physical NICs of the host server. This transparent emulation is what allows standard operating systems and applications to run in the cloud without modification.

====================

As detailed in the Huawei FusionAccess documentation for the HCIA curriculum, the Huawei Desktop Protocol (HDP) is designed to optimize the user experience in Virtual Desktop Infrastructure (VDI). Statement A is correct: HDP features "Intelligent identification of video data."8 The protocol can automatically distinguish between standard GDI (Graphics Device Interface) desktop elements and active video streams.9 When video is detected, HDP switches to specialized compression algorithms (such as H.264 or H.265) to ensure efficient encoding and reduced bandwidth consumption.

Statement B is also a verified function. HDP employsDynamic Frame Rate Adjustment.10By monitoring the network quality (latency and packet loss) in real-time, the protocol can adjust the frame rate (e.g., from 60fps down to 30fps or lower) to maintain a smooth, jitter-free playback experience even on unstable or low-bandwidth links. Statement C is true as HDP supports multiple rendering modes. In "Multimedia Redirection," the video stream is decoded on theclientside (using local hardware acceleration), while in other modes, decoding occurs on theserver(VM) with the resulting images sent to the client. This dual-support flexibility ensures compatibility across various terminal types.

Statement D isincorrectbecause of the "maximum of 2K videos" limitation. According to the official HCIA-Cloud Computing V5.5 and FusionAccess technical guides, HDP@Media technology (multimedia redirection) explicitly supports4K UHDvideo playback, not just a maximum of 2K. While D correctly mentions "automatic reconnection" and "dynamic traffic adjustment," the resolution limit is technically outdated for the current Huawei cloud ecosystem. Thus, for the purposes of the HCIA certification, only A, B, and C are fully accurate representations of HDP's high-fidelity audiovisual capabilities.

FusionAccess defines clear behaviors for desktop service adjustment:

Bis true. After reassignment, the systemautomatically starts the desktop, and a short wait time is required before user login.

Dis true. When a desktop assigned to a single user is unassigned, the systemautomatically shuts it downto save resources.

Ais false. Desktops assigned to multiple users or desktop groupscan be reassignedafter being unassigned.

Cis false. After unassignment, a desktop can beassigned to a different user, not only the original one.

Thus, the correct answers areB and D.

As detailed in the Huawei HCIA-Cloud Computing technical documentation, FusionCompute offers a robust suite of resource management functions. Statement A is correct: FusionCompute datastores support multiple file system formats to accommodate different storage backends. VIMS (Virtual Image Management System) is Huawei’s high-performance cluster file system used for SAN storage; NFS is used for Network Attached Storage; and EXT4 is used for local disk virtualization on a single host. This variety allows administrators to build heterogeneous storage pools.

Statement B is also a verified function. FusionCompute supports dynamic resource adjustment. Users can modify memory capacity for both offline VMs (while the VM is stopped) and online VMs (while running). Online memory expansion requires the "Hot Add" feature and Guest OS support, while reduction typically requires the VM to be in a state where the kernel can release the address space. Statement C accurately describes Storage Live Migration. This feature allows a VM's virtual disk files to be moved from one datastore to another (or within the same storage device) while the VM remains running, which is essential for storage maintenance and load balancing.

Statement D is incorrect because of the word "only." While traditional VM live migration (vMotion style) does require shared storage so that both hosts can see the same disk, modern versions of FusionCompute also support Shared-Nothing Live Migration. This technology migrates both the VM's memory state and its disk data simultaneously over the network, allowing a VM to move between hosts that do *not* share a common backend storage. Because D ignores this advanced capability, it is excluded from the list of correct functions in the context of FusionCompute's full feature set.

According to the Huawei HCIA-Cloud Computing curriculum, specifically the section on Huawei Desktop Protocol (HDP), the statement provided is FALSE. While the protocol does indeed perform "Intelligent Desktop Recognition" to classify bitmaps and apply different compression algorithms, the classification criteria are based on the image type (content characteristics), not the "sensitivity" of the data.

HDP classifies screen content into two primary categories:Non-natural images(such as text, lines, and desktop window frames) andNatural images(such as photographs, gradients, and video frames). For non-natural images like text, HDP uses alossless compression algorithm. This ensures that the edges of characters remain crisp and readable, preventing the "blurring" effect that can lead to eye strain. For natural images, the protocol uses alossy compression algorithm(such as H.264/H.265 based encoding). This significantly reduces the amount of data transmitted over the network while maintaining a visual quality that is acceptable to the human eye for pictorial content.

The term "non-sensitive data" used in the question is not a technical term within the HDP specification. A user's bank statement (highly sensitive) and a random text document (non-sensitive) would both be compressed using the lossless algorithm because they are both "text" content. Therefore, the compression logic is strictly content-aware to optimize the User Experience (UX) and bandwidth, regardless of the data's security classification. Understanding this distinction is vital for the exam as it highlights Huawei's "Graphics and Text Separation" technology.

====================

In FusionCompute, VM live migration between hosts withdifferent CPU modelsrequires CPU instruction compatibility. Huawei provides theIMC (Instruction Masking Compatibility) policyat the cluster level to address this issue.

TheCluster IMC policymasks advanced CPU instruction sets so that VMs only see a common subset of CPU features supported by all hosts in the cluster. This ensures that a VM can migrate safely between CNA hosts with different CPU generations or models without encountering instruction incompatibility errors.

Other options are unrelated:

I/O ring adaptationfocuses on I/O optimization.

HANA optimizationis specific to SAP HANA workloads.

Guest NUMA policyoptimizes memory access, not CPU compatibility.

Therefore, the correct answer isCluster IMC policy.
