Huawei H13-511_V5.5 Exam With Confidence Using Practice Dumps

In Huawei FusionAccess, user authentication and authorization for Windows desktops are typically integrated withActive Directory (AD). During VM template creation, the option“Configure user login”is used to specify who is allowed to log in to the virtual desktop.

According to the HCIA–Cloud Computing FusionAccess service provisioning process, this option is selected whenAD group membersare intended to access the VM. FusionAccess then uses AD-based authentication to control desktop login permissions, ensuring centralized identity management and consistent security policies.

Therefore, the correct word shown on the GUI and required to complete the sentence isAD.

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.

According to the Huawei HCIA-Cloud Computing training materials, the statement is TRUE. TAP (Network TAP) is a virtual network kernel device that is part of the standard Linux kernel networking stack.2 It is "independently maintained" because it is a native Linux feature, not a proprietary tool built solely for a specific hypervisor like KVM or Xen. TAP devices operate at the Data Link Layer (Layer 2) of the OSI model, meaning they handle Ethernet frames.3

In a cloud computing environment, TAP devices are fundamental for bridging the gap between virtual machines and the physical network. When a Virtual Machine is created, the hypervisor (CNA in Huawei's case) creates a TAP device on the host. One end of this TAP device is "plugged" into the virtual machine's NIC, while the other end is connected to a virtual switch (like the DVS or Linux Bridge). This allows the VM to send and receive Ethernet frames as if it were connected to a physical switch port.

Linux maintains TAP alongside its counterpartTUN(which operates at Layer 3/Network Layer).4Because TAP carries full Ethernet headers, it is the preferred device for virtual switches, as it allows for features like VLAN tagging and MAC address learning. Huawei’s virtualization technology leverages these standard Linux kernel features to provide a high-performance, stable networking environment. Understanding that TAP is a standard, independent Linux kernel component is vital for candidates, as it explains how open-source foundations are used to build enterprise-grade cloud platforms like FusionCompute.
