Huawei Updated H13-511_V5.5 Exam Questions and Answers by isla-rose

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 training material regarding FusionAccess Service Provisioning, the statement is TRUE. Huawei FusionAccess is designed to support complex enterprise environments, including multi-domain architectures. This is particularly relevant for large corporations that have acquired other companies or have organized their IT infrastructure into a forest of multiple Active Directory (AD) domains.

FusionAccess achieves this by establishingTrust Relationshipsbetween the "Management Domain" (where the infrastructure components like HDC and ITA are located) and the "User Domains" (where the desktop users' accounts are stored). When trust is correctly configured between AD domains, theHDC (Huawei Desktop Controller)can query and authenticate users across these boundaries. For instance, a user from marketing.huawei.com and another from research.huawei.com can both log into the same Web Interface (WI) and access their respective virtual desktops.

During the service provisioning process, the administrator adds the various domains to the FusionAccess management system. When a user logs in, they specify their domain prefix (e.g., DOMAIN_A\username), and the system routes the authentication request to the appropriate Domain Controller. This multi-domain support is critical forMulti-tenancyand large-scale enterprise consolidation. It allows a single, unified FusionAccess platform to serve multiple organizational units without requiring all users to be migrated into a single, massive AD domain. This logical separation is a key feature taught in the HCIA curriculum to demonstrate the scalability and flexibility of Huawei's virtual desktop solution.

Step 6

Convert VM into template.

Step

Operation

Technical Rationale

Step 1

Update template

Power on the VM to install the latest OS patches and software updates.

Step 2

Delete user

Remove user profiles and personal data to ensure the master image is clean.

Step 3

Remove VM from domain

Disjoin the VM from the AD domain to prevent Security Identifier (SID) or account name conflicts on new clones.

Step 4

Reset built-in administrator password

Set a secure, standardized baseline credential for the local administrator account.

Step 5

Configure template

Run theHuawei Desktop Preparation Toolto optimize the OS and encapsulate the system.

Step 6

Convert VM into template

Use the management console to officially mark the VM as a read-only template resource.

 Initialization (Steps 1-4):Before a VM can be turned into a "Golden Image," it must be stripped of its unique identity. This includes removing it from anyActive Directory (AD)domain and clearing out specific user accounts. Failing to remove the VM from the domain can lead to "duplicate computer name" errors when new desktops are provisioned from the final template.

 System Encapsulation (Step 5):The "Configure template" phase is often synonymous withSysprepor the Huawei-specific encapsulation process. This step resets the OS clock and generalizations, such as the hardware-dependent drivers, so the image can boot correctly on any host in the cluster.

 Finalization (Step 6):Once converted into a template, the VM is no longer a running instance. It becomes a master file that theITA (IT Adapter)uses for rapid service provisioning.

According to the official Huawei HCIA-Cloud Computing documentation, converting a provisioned full-copy virtual machine (VM) back into a template is a specific administrative workflow used for updating "Golden Images" without starting from a bare VM. The process must follow a logical sequence to ensure that the final template is clean, generalized, and compatible with the FusionAccess management plane.

The workflow begins withStep 1: Update template, which involves powering on the VM to install necessary software patches, security updates, or new applications. Once updated,Step 2: Delete useris performed to remove any cached user profiles, temporary files, or local user data that should not exist in the master image.Step 3: Remove VM from domainis a critical step to ensure that the VM is no longer associated with a specific Active Directory security identifier (SID) or domain account, preventing SID conflicts when the template is later used to provision multiple new desktops.

Following the domain disjunction,Step 4: Reset built-in password of administratoris required to ensure the FusionAccess system can maintain management access via a known, local credential during the subsequent automation phases.Step 5: Configure templateinvolves running theHuawei Desktop Preparation Tool. This tool performs system encapsulation (similar to Sysprep), optimizes the OS for VDI usage, and prepares the Huawei Desktop Agent (HDA). Finally,Step 6: Convert VM into templateis the final action performed in the FusionCompute or FusionAccess management console. This marks the VM as a read-only template resource, ready to be used by the ITA (IT Adapter) for rapid service provisioning.

The HCIA–Cloud Computing syllabus defines clear terminology for virtualization components.

The Guest OS is the operating system installed and running inside a virtual machine. It operates as if it were running on physical hardware, but all hardware access is abstracted by the hypervisor.

The hypervisor (A) is the virtualization layer that manages physical resources and virtual machines.

The host OS (B) is the operating system running on the physical server (in hosted virtualization models).

The host machine (D) refers to the physical server itself.

Therefore, the correct answer is Guest OS.
