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

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.

According to the HCIA–Cloud Computing virtualization domain,KVM (Kernel-based Virtual Machine)andXenare both examples ofhardware-assisted virtualizationtechnologies.

Hardware-assisted virtualization relies on CPU extensions such asIntel VT-xandAMD-Vto improve virtualization performance and isolation. Both KVM and Xen leverage these CPU features.

KVMis implemented as akernel modulewithin the Linux operating system. Once loaded, the Linux kernel itself becomes a hypervisor, managing CPU and memory virtualization with hardware support.

Xenalso relies on hardware virtualization features and interacts closely with the operating system kernel, especially in full virtualization and hardware-assisted modes.

Because the statement correctly describes both thevirtualization typeand theimplementation approach, it aligns with HCIA documentation and isTRUE.

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.
