Practice Free H13-511_V5.5 HCIA-Cloud Computing V5.5 Exam Exam Questions Answers With Explanation

In the shown topology, RTA and RTB are directly connected on10.0.0.0/24(RTA: 10.0.0.1/24, RTB: 10.0.0.2/24). RTB and RTC are directly connected on20.1.1.0/24(RTB: 20.1.1.2/24, RTC: 20.1.1.3/24). In HCIA networking fundamentals, a router forwards packets based on its routing table, and thenext hop must be reachable on a directly connected network(or resolved via recursion), meaning it is typically theneighbor router interface on the local link.

A is false: For traffic fromRTA to RTC (20.1.1.3), RTA’s next hop should beRTB’s interface 10.0.0.2(its directly connected neighbor). The address20.1.1.2is not on RTA’s directly connected subnet, so it cannot be used as the immediate next hop in this basic routing scenario.

B is true: RTC must have a route back to10.0.0.0/24(for return traffic to RTA). Since RTC only knows its directly connected network20.1.1.0/24, a static/default route is required pointing to20.1.1.2.

C is true: RTB has two directly connected networks (10.0.0.0/24 and 20.1.1.0/24), so it can reach both RTA and RTC withno additional routes.

D is false: RTB does not need extra routing configuration for RTA?RTC communication because both networks are alreadydirectly connectedon RTB.

As covered in the "Cloud Computing Trends" and "Huawei Cloud Solutions" modules of the HCIA curriculum, OpenStack and FusionCompute occupy different layers of the cloud stack. Statement A is correct: OpenStack is a global open-source project maintained by a community, whereas FusionCompute is Huawei’s proprietary commercial virtualization platform (hypervisor).4

Statement B captures a fundamental technical difference. OpenStack is anorchestratoror "Cloud OS"; it lacks an internal hypervisor and must rely on external technologies (like KVM, Xen, or FusionCompute itself) to perform the actual virtualization. In contrast, FusionCompute is a standalonevirtualization suitethat includes the CNA (hypervisor) and VRM (management), allowing it to directly pool and manage physical hardware resources.

Statement C highlights the broader scope of OpenStack, which is designed to manage heterogeneous resources, including Bare Metal (Ironic) and Containers (Zun/Magnum). FusionCompute is a specialized tool primarily focused on Virtual Machines (VMs). Finally, Statement D refers to theMulti-tenancymodel. OpenStack was built for public and large private clouds, using "Projects" and "Tenants" to strictly isolate resources and billing between different organizations. FusionCompute is a lower-level resource manager that focuses on "Clusters" and "Resource Pools" rather than the complex tenant-based isolation logic found in high-level cloud platforms. In the Huawei ecosystem, FusionCompute often serves as the "Computing" component underneath a largerHuawei Cloud Stackor OpenStack-based solution, illustrating how these two technologies complement each other in a modern data center.

According to the Huawei HCIA-Cloud Computing curriculum, statement C is FALSE regarding the architecture of a datastore. While a datastore is indeed a logical repository similar to a file system, it does not "combine storage devices of different types" into a single unified model. In FusionCompute, a datastore has a strict 1-to-1 relationship with its underlying storage resource. For example, a datastore created on an FC SAN LUN is separate from a datastore created on an NFS share or a local disk. You cannot merge a LUN from a SAN and a folder from a NAS into a single "Datastore" entity. Each datastore is formatted with a specific file system (like VIMS for block storage or NFS for file storage) that is native to that specific storage type.

The other statements represent the core principles of storage virtualization in the Huawei ecosystem. Statement A is true; LUNs from Huawei's distributed block storage (FusionStorage) are presented to hosts as block devices and can then be initialized as VIMS datastores. Statement B is a fundamental definition ofVirtualized Storage: the hypervisor uses a cluster file system (VIMS) to hide the complexities of the hardware, allowing each VM to exist simply as a set of files (configuration files, disk files like .vhd, and log files) inside a directory.

Statement D is also correct; storage virtualization significantly improves utilization through technologies likeThin Provisioning. In a traditional environment, if you allocate 100GB to a server, that space is "locked." In a virtualized environment with thin provisioning, the datastore only consumes the actual physical space being used by the data, allowing administrators to "over-allocate" storage and maximize the efficiency of their physical disk arrays.

Service Model

Description

Infrastructure as a Service (IaaS)

The cloud platform provides infrastructure (such as servers, storage devices, networks, and virtual resources) and maintains related resources. Users only need to focus on systems and applications.

Platform as a Service (PaaS)

The cloud platform provides infrastructure (such as servers, storage devices, networks, and virtual resources) and application deployment environment (such as operating systems, middleware, and software running environment) and maintains related resources. Users only need to focus on applications and data.

Software as a Service (SaaS)

The cloud platform provides all resources, services, and maintenance. Users only need to use applications.

According to the official Huawei HCIA-Cloud Computing curriculum, cloud services are categorized into three standard models:IaaS, PaaS, and SaaS, distinguished by the boundary of responsibility between the provider and the user.

In theIaaS(Infrastructure as a Service) model, the provider is responsible for the physical and virtualized hardware resources, including compute, networking, and storage. The user retains control over the "system" level, meaning they must install and manage the operating system, middleware, and applications. This model offers the highest level of flexibility and is the foundation for Huawei's FusionCompute services.

PaaS(Platform as a Service) moves the boundary higher. The cloud platform provides not only the infrastructure but also the entire development and deployment environment. This includes the operating system, database management systems, and middleware. The user is relieved of system maintenance and only needs to focus on the "applications and data" layer. This model is ideal for developers who want to deploy software without managing the underlying server stack.

Finally,SaaS(Software as a Service) represents the highest level of abstraction. The provider manages the entire stack, from hardware to the application itself. Users simply access and "use the application" via a web browser or client. The user has no responsibility for maintenance, updates, or infrastructure scaling. Understanding these models is critical for the HCIA exam as it defines how Huawei Cloud Stack delivers different value propositions to enterprise customers.

In the FusionAccess architecture, the successful startup and availability of a virtual desktop depend on a process known as "VM Registration." According to the Huawei HCIA-Cloud Computing curriculum, the component responsible for receiving and processing these registration requests is the HDC (Huawei Desktop Controller).

The process works as follows: Each virtual desktop VM has a resident software agent called theHDA (Huawei Desktop Agent). When the VM boots up and the network is initialized, the HDA sends a registration request over the internal management network. This request contains the VM's status, its IP address, and its unique identifier. TheHDCacts as the central "command and control" center of the desktop cloud. It listens for these requests, verifies the VM's credentials against the system database (GaussDB), and updates the VM's status to "Ready" or "In Use."

The HDC is the core logical component that manages the relationship between users and their virtual desktops. If the HDC does not receive the registration request—perhaps due to a network issue or a failure of the HDA service on the VM—the desktop will appear as "Unregistered" or "Offline" in the management portal, and users will be unable to log in through the Web Interface (WI). While theITA (IT Adapter)is used by administrators totriggerthe provisioning of the VM, it does not handle the real-time registration traffic of individual VMs. Similarly, the HDA is thesenderof the request, not the receiver. Understanding the HDC's role as the registration authority is a fundamental requirement for troubleshooting connection issues and mastering the FusionAccess component interactions taught in the HCIA certification.

Huawei FusionComputeHigh Availability (HA)is designed to improve service continuity by automatically responding to VM or host failures.

OptionAis true. FusionCompute allows administrators to configuredifferent HA policiesfor virtual machines based on service importance, which aligns with SLA-driven management principles.

OptionCis true. One of the core functions of HA isautomatic VM rebootwhen a virtual machine encounters a failure, ensuring rapid service recovery.

OptionDis true. FusionCompute continuously monitorsCNA host and VM status. If a CNA host fails, HA triggers VM migration or restart on another available host in the same cluster, minimizing downtime.

OptionBis false. Even when usingshared storage, HAdoes not guarantee zero data loss. HA focuses onservice recovery, not data consistency. Data loss may still occur depending on application state and write operations at the time of failure.

Therefore, the false statement isB.

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.

In the official Huawei FusionAccess documentation, "Quick Provisioning" is a streamlined workflow designed to deploy multiple virtual desktops efficiently.1 For this process to succeed, several mandatory parameters must be defined to ensure the Virtual Machines (VMs) are created with the correct hardware and software specifications.

First, theComputer Type (A)is mandatory as it determines whether the desktops will be "Full Copy" (independent disks) or "Linked Clone" (shared base disk). This choice significantly impacts storage consumption and future maintenance. Second, aTemplate (D)is required because it serves as the "Golden Image" containing the pre-installed Operating System, drivers, and the Huawei Access Agent (HDA). Without a template, the system cannot instantiate the VM's disk content. Third, a targetHost (B)or resource cluster must be selected to provide the physical CPU and memory resources required for the VMs to run.

WhileSecurity Groups (C)are an important part of the network configuration, they are typically associated with a "Desktop Group" rather than being a mandatory field in the quick provisioning wizard itself. If no specific security group is selected, the system often applies a default policy. According to the HCIA curriculum, the core "Provisioning Plan" focuses on the source (Template), the deployment mode (Computer Type), and the destination (Host/Cluster). Ensuring these three parameters are correctly matched is vital for the automated provisioning engine to calculate resource availability and successfully trigger the VM creation on the backend FusionCompute platform.

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

The HCIA–Cloud Computing syllabus explains that routers are responsible forinter-network communicationand packet forwarding based onIP addresses. In the TCP/IP reference model, this function corresponds to theNetwork layer.

Routers analyze the destination IP address of a packet and use routing tables and routing protocols to determine thebest pathfor forwarding the packet to its destination. This behavior is distinct from switches, which forward frames based on MAC addresses at the data link layer.

TheData link layer (A)is associated with switches, theTransport layer (D)handles end-to-end communication (such as TCP and UDP), and theApplication layer (C)provides services to applications.

Therefore, according to HCIA–Cloud Computing network fundamentals, the correct answer isNetwork layer.

According to the HCIA–Cloud Computing virtualization domain,KVM (Kernel-based Virtual Machine)andXenare both examples ofhardware-assisted virtualizationtechnologies.

Hardware-assisted virtualization relies on CPU extensions such asIntel VT-xandAMD-Vto improve virtualization performance and isolation. Both KVM and Xen leverage these CPU features.

KVMis implemented as akernel modulewithin the Linux operating system. Once loaded, the Linux kernel itself becomes a hypervisor, managing CPU and memory virtualization with hardware support.

Xenalso relies on hardware virtualization features and interacts closely with the operating system kernel, especially in full virtualization and hardware-assisted modes.

Because the statement correctly describes both thevirtualization typeand theimplementation approach, it aligns with HCIA documentation and isTRUE.

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.

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.

In the HCIA–Cloud Computing virtualization domain, the hypervisor is the core software layer responsible for abstracting and managing physical compute resources and enabling multiple virtual machines to run on a single physical host.

A hypervisor is also commonly referred to as a Virtual Machine Monitor (VMM). The VMM directly manages CPU scheduling, memory allocation, and virtual device access for guest operating systems.

The other options are not equivalent to a hypervisor:

VRM (Virtual Resource Management) refers to centralized management components used in platforms like FusionCompute.

VNM (Virtual Network Management) relates to virtual networking control.

VPM (Virtual Power or Performance Management) is not a hypervisor concept in HCIA materials.

Therefore, the correct answer is VMM.

According to the HCIA–Cloud Computing FusionAccess module, different desktop types are designed for different business workloads.

New media operationstypically involve tasks such as video editing, image processing, animation rendering, and real-time previewing. These workloads aregraphics-intensiveand require high-performance GPU acceleration.

Design-oriented GPU graphics cloud desktopsare specifically designed to support:

GPU pass-through or vGPU acceleration

High-resolution displays

Graphics rendering and multimedia processing

Professional applications used in media, design, and creative industries

Secure office desktops focus on data protection rather than performance. General office desktops target routine tasks such as documents and emails. Public terminal desktops are designed for shared access and lightweight workloads.

Therefore, the most suitable desktop type for new media operations isDesign-oriented GPU graphics cloud desktops.

In the "Virtualization Basics" section of the Huawei HCIA-Cloud Computing training material, the taxonomy of virtualization components is strictly defined. Statement C is FALSE because the virtualization software layer is technically called the Hypervisor or Virtual Machine Monitor (VMM), not the "Host OS." While a "Host OS" exists in Type-2 (hosted) virtualization (where the hypervisor runs as an application on top of an existing OS like Windows or Linux), the software layer that actually performs the resource abstraction and logical partitioning is the Hypervisor itself.

The other definitions are central to Huawei's technical documentation. AGuest OS(Statement A) is indeed the operating system—such as Windows Server or Ubuntu—that is installed inside a Virtual Machine. It is "unaware" that it is running on virtual hardware. TheHost Machine(Statement B) refers to the underlying physical server (e.g., a Huawei FusionServer Pro) that provides the actual CPU, RAM, and physical NICs. Finally, aGuest Machine(Statement D) is a synonym for a Virtual Machine (VM), representing the logical container that houses the Guest OS and applications.

In a Type-1 virtualization architecture (like HuaweiFusionCompute), the Hypervisor (CNA) sits directly on the hardware. In this scenario, there is no "Host OS" at all, further proving why statement C is incorrect. The Hypervisor is responsible for trapping "privileged instructions" from the Guest OS and translating them into actions on the physical hardware. Correctly identifying these roles—Host Machine, Hypervisor, and Guest VM—is a prerequisite for understanding more advanced cloud features like Resource Clusters and Distributed Resource Scheduling (DRS).

During quick provisioning in FusionAccess:

Administrators mustselect a VM template.

AVM groupmust be specified for management purposes.

Thenumber of VMsto be provisioned must be entered.

However,desktop group selectionis not required at the VM creation stage. Desktop groups are associatedlater during desktop assignment, not during VM creation.

Therefore, the correct answer isC.

Terminal Security

?Security hardening customized for TC systems

Focuses on endpoint protection

Prevents data from being stored locally on thin clients

Enhances terminal OS security and access control

Transmission Security

?Security gateway firewall

Protects data during network transmission

Controls and filters access traffic

Prevents unauthorized access and attacks during desktop access

Cloud Security

?Security watermark and secure deletion

Ensures data traceability through watermarks

Prevents data leakage

Guarantees secure deletion of cloud-side data

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.

Quick provisioning using alinked clone templateis designed to rapidly deploy desktops while ensuring standardization and automation.

According to HCIA–Cloud Computing FusionAccess service provisioning procedures, the quick provision workflow includes:

Creating the VMbased on the linked clone template and snapshot.

Renaming the VMto meet enterprise naming rules.

Adding the VM to the domain, enabling centralized authentication and policy control.

Associating the VM with a user or user group, which determines desktop assignment and access permissions.

All listed operations are integral steps in the linked clone quick provisioning process. Therefore,all options are correct.

In FusionAccess deployment,vAG (Virtual Access Gateway)andvLB (Virtual Load Balancer)rely oninternal account authentication and synchronizationto maintain high availability (HA) status.

Changing the following passwords can directly affect HA synchronization:

root password for vAG/vLB (D)

gandalf account password for vAG/vLB (C)

root password for HDC (A), which may disrupt management communication

However, theITA portal login password (B)is related only touser or administrator portal accessand doesnot participate in HA synchronization mechanisms.

Therefore, changing the ITA portal login password isnota cause of abnormal HA status.

In the context of FusionAccess deployment, understanding Microsoft Active Directory (AD) is critical. According to the official Huawei curriculum, a Domain and an Organizational Unit (OU) serve different purposes in a network hierarchy. Statement A is TRUE because a domain is a security and administrative boundary; users authenticate "to the domain." An OU is merely a logical container inside that domain used for organization; it does not function as an authentication boundary itself.

Statement B isTRUE. Group Policy Objects (GPOs) are the primary tool for managing desktop settings in a Huawei VDI environment. GPOs can be linked at the Domain level (applying to everyone) or at the OU level (applying only to the users or computers within that specific folder). This allows FusionAccess administrators to apply specific security rules—such as disabling USB ports or setting custom wallpapers—to one department (one OU) without affecting the entire company.

Statement D is alsoTRUE. Both entities are containers for AD objects such as User accounts, Computer accounts, and Security Groups. However, statement C isFALSE. While an OU always existsinsidea domain (to organize that domain's objects), a domaincannotexist inside an OU. Domains exist within a Forest or Tree structure.2This distinction is vital for HCIA candidates because the FusionAccessITA (IT Adapter)requires a specific OU structure to be pre-created (e.g., an OU for Desktops and an OU for Users) to properly apply the automated provisioning and management policies that define the desktop cloud environment.

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

All four statements accurately describe keyinitialization and configuration principlesof FusionAccess:

Ais true: When Windows AD is interconnected and local authentication is disabled,AD authentication has higher prioritythan LiteAS.

Bis true: vAG/vLB deployment requires properWI cluster configurationto enable access services.

Cis true: To avoid backup data loss caused by infrastructure failures,external FTP backup serversare recommended in production networks.

Dis true: When a License supports multiple charging modes, administrators must explicitly chooseUser Count or Concurrent User Count.

Thus,all options are correct.

Cloud-native architecture emphasizesapplication-level design and management, focusing on agility, scalability, and resilience.

Microservices,containers, andservice meshesare core cloud-native technologies.

Virtualizationis a foundational cloud technology but belongs totraditional cloud infrastructure, not cloud-native application architecture.

Therefore, the correct answer isVirtualization.

In the Huawei FusionAccess solution, desktop provisioning is the process of creating and assigning virtual machines to users. The "provisioning proportion mode" is a key parameter in this process. Mode A (1:1) represents the "Single User" or "Static" assignment mode. In this configuration, one virtual machine is permanently bound to one user. This is typically used for Full Copy desktops where the user requires a persistent environment with their own dedicated storage and personalized settings. The user has exclusive rights to the VM, and their data remains on the disk even after logging off. This ensures the highest level of personalization and performance for individual employees.

Mode B (1:N) represents the "Dynamic" or "Pool" assignment mode. In a 1:N scenario, a group of users shares a pool of virtual machines. This is commonly implemented using Linked Clone technology to save storage space and simplify management. For example, in a task-oriented environment like a call center or a training center, multiple users (N) can log into a set of virtual machines based on the same template (1) at different times. The system assigns an available VM from the pool to the user upon login. This maximizes resource utilization because not all users are online simultaneously.

Furthermore, the selection of these modes directly affects the backend storage design and the maintenance strategy. For 1:1 desktops, backup and disaster recovery must be managed per individual VM, whereas for 1:N pooled desktops, the administrator focuses on the security and integrity of the "Golden Image" or parent template. Understanding these two primary modes is crucial for administrators to choose the right technology—Full Copy for persistent 1:1 needs or Linked Clone for efficient 1:N pools—based on user requirements and hardware capacity.

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

According to the Huawei HCIA-Cloud Computing curriculum and the FusionAccess Maintenance Guide, the statement is FALSE. While it is a recommended best practice to restart infrastructure virtual machines (VMs) approximately once every quarter to clear system cache, refresh memory resources, and ensure long-term stability, the method of execution described in the statement is incorrect and dangerous for production environments.

Infrastructure VMs in FusionAccess—such as theWI (Web Interface),HDC (Huawei Desktop Controller),ITA (IT Adapter), andGaussDB (Database)—are the "brains" of the desktop solution. Most of these components are deployed in active/standby or load-balancing pairs to ensure High Availability (HA). If an administrator were to run the reboot command on all Linux infrastructure VMs "at the same time," it would cause a complete service interruption. During this period, users would be unable to log in to their desktops, the management portal would be inaccessible, and active desktop sessions might lose their connection persistence.

The official Huawei documentation mandates astaggered restartapproach. For example, if there are two WI nodes, the administrator should restart the first node, verify it has returned to service, and only then proceed to restart the second node. This ensures that the "Service Plane" remains active at all times. Additionally, restarts should always be performed during off-peak hours to minimize the impact of the brief transition period between active and standby nodes. Therefore, while the frequency (quarterly) is correct, the instruction to restart them all simultaneously contradicts the fundamental principles of high-availability management within the Huawei ICT framework.

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

In FusionAccess, full copy desktops are created by completely copying the template into an independent virtual machine. After the VM is created, it no longer depends on the template.

According to HCIA–Cloud Computing materials:

Modifying or deleting a full copy template does not affect already provisioned desktops.

Only linked clone desktops depend on the template and snapshot chain.

Therefore, the statement is FALSE.

According to the HCIA–Cloud Computing curriculum underServer Basics, the CPU is defined as thecore component responsible for computation and controlwithin a computer system. The CPU executes program instructions and coordinates the operation of all other hardware components.

The CPU is primarily composed of two main functional units:

Arithmetic Logic Unit (ALU):Responsible for performing arithmetic operations (such as addition and subtraction) and logical operations (such as comparisons and logical AND/OR).

Control Unit (Controller):Responsible for fetching instructions from memory, decoding them, and controlling the execution process by issuing control signals to other components.

The CPU operates based on thefetch–decode–execute cycle, which is a fundamental concept emphasized in HCIA learning materials. During this process, the CPU reads instructions and related data from memory, processes them, and produces results according to the instruction set architecture.

Because the statement accurately describes therole, composition, and working principleof the CPU as defined in Huawei’s HCIA–Cloud Computing documentation, it iscorrect.

According to the HCIA–Cloud Computing curriculum, the evolution of cloud computing architecture reflects changes intechnology openness, business importance, resource scale, and data characteristics.

OptionAis correct because early cloud platforms were often proprietary and closed, while modern cloud computing architectures increasingly adoptopen-source technologies(such as OpenStack and Kubernetes) and open architectures to improve interoperability and innovation.

OptionBis also correct. Cloud computing initially hostednon-critical workloadssuch as testing, development, and backup systems. As reliability, security, and availability improved, cloud platforms became capable of supportingmission-critical enterprise applications, including ERP, financial systems, and core business services.

OptionDcorrectly describes the evolution of cloud architecture. Early virtualization focused onsmall-scale resource integration, while modern cloud computing emphasizeslarge-scale resource pools, enabling centralized management, elastic scheduling, and efficient utilization of massive compute, storage, and network resources.

OptionCisfalse. The evolution of cloud computing data has movedfrom structured data to semi-structured and unstructured data, not the other way around. With the rise of big data, IoT, social media, logs, images, and videos, cloud platforms are increasingly designed to processmassive volumes of unstructured and semi-structured data, which is a key trend emphasized in HCIA learning materials.
