H13-511_V5.5 Exam Dumps - HCIA-Cloud Computing V5.5 Exam

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 consists of multiple components, each with different roles and data persistence requirements.

WI (Web Interface)stores configuration and user access information and supports backup.

VLB (Virtual Load Balancer)maintains configuration data that can be backed up.

vAG (Virtual Access Gateway)also stores configuration-related data that supports backup and recovery.

TheLicensecomponent, however, isnot backed upas configuration or system data. Licensing information is typically re-imported or reactivated during recovery rather than restored from backup.

Therefore, the component that doesnothave backup data isLicense.

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.

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

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.

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.

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.

As defined in the "Network Technology Basics" module of the HCIA-Cloud Computing training, a router is a Layer 3 (Network Layer) device responsible for interconnecting different network segments and selecting the optimal path for data packets. To perform this function, the router maintains and manages a Routing Table. This table is the "map" of the network that the router uses to make forwarding decisions. Every entry in the routing table typically includes several key parameters: the destination network address, the subnet mask, the protocol (how the route was learned, such as Static, OSPF, or BGP), the preference value, the cost (metric), and the next-hop address or outbound interface.

When a router receives an IP packet, it examines the destination IP address and performs a lookup in its routing table to find the most specific match (longest match rule). If a matching entry is found, the router encapsulates the packet into a new frame and sends it toward the next hop. If no match is found and no default route exists, the packet is discarded. This process is fundamental to the operation of a Cloud Data Center where multiple Virtual Private Clouds (VPCs) and subnets must communicate through virtual or physical routers.

While a switch manages a MAC address table to forward frames at Layer 2, and a host manages an ARP table to map IP addresses to MAC addresses, only the routing table provides the cross-network path intelligence required for routing. In Huawei’s virtualization solutions, virtual routers within the software-defined networking (SDN) layer use these same logic principles to ensure that traffic between virtual machines in different subnets is directed efficiently to the correct destination. Proper management of the routing table is therefore the cornerstone of network reachability in cloud environments.
