Pass the Huawei HCIA-Cloud Computing H13-511_V5.5 Questions and answers with Dumpstech

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

The HCIA–Cloud Computing syllabus explains that routers are responsible for inter-network communication and packet forwarding based on IP addresses. In the TCP/IP reference model, this function corresponds to the Network layer.

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

The Data link layer (A) is associated with switches, the Transport layer (D) handles end-to-end communication (such as TCP and UDP), and the Application layer (C) provides services to applications.

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

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

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

Option A is correct. A guest OS refers to the operating system installed and running inside a virtual machine.

Option B is correct. A guest machine is another term for a virtual machine (VM).

Option C is correct. A host machine typically refers to the physical server that provides hardware resources for virtualization.

Option D is false. A host OS is not the virtualization software layer. The virtualization layer is the hypervisor (such as KVM, Xen, or FusionCompute). In some architectures, the host OS and hypervisor may coexist, but they are not the same concept.

Therefore, the false statement is D.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

When creating a Windows template in FusionAccess, the Template Tool must be mounted and installed inside the VM.

According to HCIA documentation:

The template tool installs necessary drivers, services, and agents required for desktop provisioning, management, and optimization.

Without mounting and installing the template tool, the VM cannot be converted into a usable desktop template.

Other operations such as configuration and conversion are subsequent steps, but mounting the template tool is mandatory.

Therefore, the correct answer is A.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

In Huawei FusionCompute, VIMS is a storage virtualization file system designed specifically for Huawei’s virtualization platform.

Option A is true. VIMS underpins advanced storage features such as thin provisioning, snapshots, and live storage migration, which are core functions in FusionCompute.

Option B is true. VIMS supports multiple backend storage types, including FC SAN, IP SAN, and local disks, offering flexible deployment options.

Option D is true. VIMS is a high-performance cluster file system optimized for virtualized environments and concurrent access.

Option C is false. VIMS is not a universal industry-standard file system. It is a Huawei-specific storage virtualization file system, designed for FusionCompute and not broadly adopted across all vendors.

Thus, the false statement is C.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

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

Each zone is logically and physically isolated

Each zone has its own FusionAccess system

Data is not allowed to flow freely between zones

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

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

In FusionAccess deployment, vAG (Virtual Access Gateway) and vLB (Virtual Load Balancer) rely on internal account authentication and synchronization to 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, the ITA portal login password (B) is related only to user or administrator portal access and does not participate in HA synchronization mechanisms.

Therefore, changing the ITA portal login password is not a cause of abnormal HA status.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

The HCIA–Cloud Computing syllabus clearly defines responsibility boundaries for IaaS. In the IaaS model, the cloud provider delivers basic infrastructure resources, including compute, storage, networking, and virtualization. The user is responsible for managing operating systems, middleware, runtime environments, applications, and data.

Option A is false because virtualization is managed by the cloud provider, not the user. In IaaS, users consume virtualized resources (such as ECS instances) but do not deploy or maintain the underlying hypervisors or virtualization platforms.

Option B is false. Only focusing on applications aligns with the SaaS model, where the provider manages everything else. In IaaS, users must also manage operating systems and system-level configurations.

Option C is also false. Focusing only on applications and data corresponds more closely to PaaS, where the platform handles operating systems and runtime environments.

Option D is the correct description of IaaS responsibilities, because users must manage operating systems (systems) and applications, while the provider manages the infrastructure layer. Therefore, D is not false and is excluded from the answer.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

VM live migration in FusionCompute has several mandatory prerequisites.

A is required because live migration applies only to running VMs.

B is required to ensure uninterrupted network connectivity during migration.

D is required because both source and target hosts must access the same datastore to migrate VM disks seamlessly.

IMC policy (C) is not mandatory for live migration. It is required only when hosts have different CPU models. If hosts use compatible CPUs, live migration can proceed without configuring IMC.

Therefore, the correct answer is C.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

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

Microservices, containers, and service meshes are core cloud-native technologies.

Virtualization is a foundational cloud technology but belongs to traditional cloud infrastructure, not cloud-native application architecture.

Therefore, the correct answer is Virtualization.

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

This statement is incorrect based on HCIA–Cloud Computing virtualization concepts.

First, KVM is not a pure paravirtualization technology. It is a hardware-assisted full virtualization solution 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 supports device I/O virtualization. Using technologies such as Virtio, 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 is FALSE.
