H13-511_V5.5 Huawei HCIA-Cloud Computing V5.5 Exam Free Practice Exam Questions (2026 Updated)

The HCIA–Cloud Computing syllabus clearly defines the basic terminology used in virtualization.

OptionAis correct. Aguest OSrefers to the operating system installed and running inside a virtual machine.

OptionBis correct. Aguest machineis another term for a virtual machine (VM).

OptionCis correct. Ahost machinetypically refers to thephysical serverthat provides hardware resources for virtualization.

OptionDis false. Ahost OS is not the virtualization software layer. The virtualization layer is thehypervisor(such as KVM, Xen, or FusionCompute). In some architectures, the host OS and hypervisor may coexist, but they arenot the same concept.

Therefore, the false statement isD.

According to the Huawei HCIA-Cloud Computing training materials, the statement is FALSE. In a Distributed Virtual Switch (DVS), a port group is a management object used to define common attributes for a collection of virtual ports. These attributes include VLAN settings, security policies, and Quality of Service (QoS) parameters. When an administrator configures a priority (such as an 802.1p priority tag) within a port group, that configuration applies to the entire port group, meaning all VMs connected to that group share the same policy.

The system does not allow for the setting of individual "priorities" for each specific member port (VM port) directly within the port group configuration. Instead, the port group ensures consistency across the virtual network. If different VMs required different priorities, they would typically be placed into different port groups, each with its own specific QoS and VLAN configuration.

It is important to distinguish this fromUplink Groups. In an uplink group (which connects the DVS to physical network cards), administratorscanset priorities or active/standby states for physical member ports (NICs) to control traffic flow and redundancy. However, for the virtual ports used by VMs within a standard port group, the logic is based on uniform policy enforcement. Huawei's documentation emphasizes that port groups are designed to simplify management by allowing the administrator to configure a policy once and have it apply to all associated VM NICs, thereby reducing the risk of manual configuration errors on a per-port basis.

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

According to the Huawei HCIA-Cloud Computing documentation, specifically within the "Planning and Deployment of FusionAccess" module, the network architecture of a cloud data center is divided into distinct planes to ensure security, isolation, and efficient management. In a FusionAccess deployment, infrastructure virtual machines (VMs)—which include critical components such as the ITA (IT Adapter), HDC (Huawei Desktop Controller), WI (Web Interface), and the GaussDB database—are considered the "management brain" of the desktop cloud solution.

TheManagement planeis specifically designed to facilitate communication between management systems and all nodes within the cloud environment. In the provided scenario, the network segment192.168.10.0/24(VLAN 10) is designated as the FusionCompute Management plane. Huawei's official best practices dictate that Linux infrastructure VMs must be deployed on this plane to allow them to communicate directly with theVirtual Resource Management (VRM)node and theComputing Node Agent (CNA)hosts. This placement ensures that management traffic for desktop provisioning and resource orchestration remains isolated from general user traffic and heavy storage data flows.

In contrast, theService plane(192.168.30.0/24) is intended for the traffic of standard user applications, while theService desktopsegment (192.168.108.0/22) is reserved for the end-user virtual desktops themselves. Placing infrastructure VMs on theStorage plane(192.168.20.0/24) would be technically incorrect, as it is strictly dedicated to disk I/O and would not provide the necessary logical path to the management portal. Therefore, selecting network segment B ensures that infrastructure components are securely positioned to manage the desktop lifecycle while maintaining high availability and administrative accessibility.

In FusionAccess,templates must not be joined to a domain.

HCIA–Cloud Computing materials specify that:

Templates are created in aworkgroup environment.

Domain joining is performed during desktop provisioning, not at the template stage.

Joining a template to a domain can cause conflicts such as duplicate computer accounts.

Therefore, the statement isFALSE.

In FusionCompute architecture,CNAandVRMhave clearly defined deployment models.

OptionAis false.CNA is deployed only on physical servers(compute nodes). It is responsible for interacting directly with hardware resources and cannot run inside a VM.

OptionBis true. When VRM is deployed on physical servers,active and standby VRM nodes must be installed on separate physical serversto ensure high availability.

OptionCis true. When VRM is deployed on virtual machines, the active and standby VRM VMs must be placed ondifferent hosts within the management clusterto avoid single points of failure.

OptionDis true. VRM supports deployment oneither physical servers or virtual machines, providing flexible management options.

Therefore, the correct answers areB, C, and D.

In the official Huawei HCIA-Cloud Computing documentation, specifically the "FusionAccess Security" module, the system is described as having a multi-layered security architecture. These four access management policies are the primary tools used to control entry into the virtual desktop environment.

MAC address-based control (A)allows administrators to bind specific users or groups to authorized hardware devices. This ensures that even if a password is compromised, the user can only log in from a company-issued terminal.Time-based control (B)functions as a whitelist; it defines a "valid window" (e.g., 08:00 to 18:00) during which desktop access is permitted. Outside of these hours, the system rejects connection attempts, which is critical for managing contractors or ensuring compliance with labor regulations.

IP address-based control (C)is highly flexible, supporting both blacklists (to block known malicious ranges) and whitelists (to allow only local office subnets). Administrators can define these rules for individual IPs or entire CIDR blocks. Finally,Certificate-based control (D)provides the highest level of identity assurance. Unlike the other policies which can be granular, certificate authentication is typically a global system setting in the ITA/HDC configuration. When enabled, every client must present a valid digital certificate issued by a trusted Certificate Authority (CA) before they are even prompted for a username and password.

By combining these policies, Huawei FusionAccess creates a "Zero Trust" style environment where access is granted based on the user's identity, their physical device, their location (IP), and the time of day. Understanding how to configure these policies in theITA (IT Adapter)portal is a key requirement for the HCIA-Cloud Computing certification and essential for maintaining a secure enterprise desktop cloud.

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

In standard FusionAccess architecture, a site generally requiresone pair of vLBs(active/standby) to provide load balancing and high availability for user access traffic.

Additional vLB pairs are only required inlarge-scale or multi-site deployments. For most enterprise scenarios described in HCIA materials,one pairis sufficient.

Therefore, the correct answer is1 pair.

This statement isincorrectbased on HCIA–Cloud Computing virtualization concepts.

First,KVM is not a pure paravirtualization technology. It is ahardware-assisted full virtualizationsolution that relies on CPU virtualization extensions. While KVM can use paravirtualized drivers (such as Virtio) to improve performance, its core architecture is hardware-assisted virtualization.

Second, KVM supportsdevice I/O virtualization. Using technologies such asVirtio, KVM provides efficient virtual network and storage devices. This allows virtual machines to achieve near-native I/O performance, which is a key feature emphasized in HCIA training.

Because the statement incorrectly classifies KVM and wrongly claims that it cannot virtualize device I/O, the correct answer isFALSE.

In the Huawei HCIA-Cloud Computing curriculum, understanding the classification and reservation of IPv4 addresses is essential for proper network configuration within a virtualized data center. According to official documentation, certain address ranges are reserved for specific protocols or system functions and are strictly prohibited from being assigned to service hosts (end-user devices or servers).

Firstly,0.0.0.0is an unspecified address. It is used by a host that does not yet have an IP address when it sends a DHCP Discover packet to find a server. It also represents the "default route" in routing tables. Secondly, the127.0.0.0/8range is reserved for loopback testing. Any packet sent to this range never leaves the local host's internal network stack; it is used to verify that the TCP/IP suite is installed correctly. Thirdly,255.255.255.255is the "limited broadcast address." It is used to send data to every device on the current local network segment but is never routed across different subnets. Finally, the169.254.0.0/16range (represented here as a /24 subnet) is the Automatic Private IP Addressing (APIPA) range. If a host is configured to obtain an IP automatically but fails to contact a DHCP server, the operating system assigns an address from this range so the host can still communicate with others on the same link.

None of these addresses can be used as a source or destination for standard service traffic across a routed cloud infrastructure. Service hosts must be assigned either public IP addresses or private IP addresses from the RFC 1918 ranges (10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16). Assigning reserved addresses to service hosts would lead to routing conflicts, local loopback errors, or a complete failure of network communication within the Huawei FusionCompute or FusionAccess environment.

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

In the Huawei HCIA-Cloud Computing curriculum, network management and storage management are distinct functional areas. The technologies listed in options A, C, and D are all integral to the networking stack of a virtualized environment. A Distributed Virtual Switch (DVS) is used to manage the logical network across multiple physical hosts.1 A Virtual NIC (vNIC) is the virtualized network interface that provides connectivity for a Virtual Machine.2 Network I/O Control is a feature used to manage and prioritize network traffic bandwidth (Quality of Service) to ensure that critical services receive the necessary throughput.3

However, aSnapshotis strictly a data management and protection technology, not a networking tool.4According to the official training materials, a snapshot records the status of a Virtual Machine's data (specifically its virtual disks and, optionally, its memory state) at a specific point in time.5This allows an administrator to "roll back" the VM to a previous state in case of software failure, a botched update, or data corruption.6While a snapshot captures theconfigurationof the network settings that existed at that time, it does not "manage" the network itself. It does not handle frame forwarding, VLAN tagging, or traffic shaping.

In the context ofFusionCompute, snapshots are managed at the storage layer (VIMS or local storage). They are used for disaster recovery and testing. Using a snapshot to attempt network management would be a fundamental misunderstanding of the architecture. Therefore, within the HCIA framework, students must distinguish between "Connectivity/Control" (Networking) and "Persistence/State" (Storage/Snapshots). This distinction ensures that administrators apply the correct tools for specific operational tasks, such as using the DVS for traffic isolation and snapshots for data backup.

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

RAID technology is a key topic in theStorage Technology Basicsdomain of HCIA–Cloud Computing. Different RAID levels provide varying balances of performance, capacity, and fault tolerance.

RAID 0 (A)uses data striping across multiple disks to improve read/write performance but providesno data redundancy. This statement is correct.

RAID 1 (C)usesdisk mirroring, where identical data is written to two disks, ensuring high data reliability. This statement is correct.

RAID 5 (D)usesdistributed parityacross disks, allowing data recovery if one disk fails. This is also correct.

RAID 6 (B)is the false statement. RAID 6 doesnotuse mirroring. Instead, it usesdual parity, allowing the system to tolerate the failure oftwo disks simultaneously.

Therefore, optionBis incorrect and is the false statement.

VLAN technology is a fundamental topic in HCIA–Cloud Computing, especially for cloud network isolation and segmentation.

OptionAis false. Atrunk linkis designed to carry traffic frommultiple VLANs using VLAN tags (802.1Q). Untagged traffic typically belongs to anative VLAN, not multiple VLANs.

OptionBis false. Ahybrid interfacecanbe used to connect a switch to a server. Hybrid interfaces support both tagged and untagged VLAN traffic and are commonly used in server and virtualization scenarios.

OptionCis true.Trunk interfacesare primarily used to connectswitch-to-switchlinks, allowing multiple VLANs to pass between switches.

OptionDis false.Access interfacesare designed to connectend devices(such as PCs or printers) and carry traffic foronly one VLAN, not for switch interconnections.

Therefore, the false statements areA, B, and D.

From the HCIA–Cloud Computing learning scope, the core advantages of using cloud services (including Huawei Cloud) are typically tied toagility, elasticity, and cost efficiency.

Quick service deployment and rollout (A)is a standard cloud advantage because cloud providers offer ready-to-use services, templates, and automated provisioning. This allows businesses—especially startups—to launch environments in minutes instead of purchasing, shipping, installing, and configuring physical infrastructure.

Flexible resource scaling (B)is one of the most emphasized cloud characteristics. Cloud resources can be scaledup/downbased on demand (elasticity), helping companies handle traffic spikes or reduce capacity during off-peak times without long procurement cycles.

Reduced hardware costs (D)is also a common advantage because the company avoids large upfront capital expenses (CapEx) for servers, storage, and networking. Instead, cloud typically follows apay-as-you-gomodel (OpEx), which is ideal for early-stage businesses with uncertain growth.

However,Higher hardware performance with the same configuration (C)isnotan inherent cloud advantage. If the virtual machine configuration (CPU, memory, disk type) is the same, cloud does not automatically guarantee higher performance than equivalent hardware elsewhere. Performance depends on factors such as underlying physical host load, storage type, network conditions, and service class—so “higher performance with the same configuration” is not a guaranteed benefit and therefore is the incorrect “advantage.”
