Selected H13-511_V5.5 HCIA-Cloud Computing Questions Answers

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

OptionAis correct. Aguest OSrefers to the operating system installed and running inside a virtual machine.

OptionBis correct. Aguest machineis another term for a virtual machine (VM).

OptionCis correct. Ahost machinetypically refers to thephysical serverthat provides hardware resources for virtualization.

OptionDis false. Ahost OS is not the virtualization software layer. The virtualization layer is thehypervisor(such as KVM, Xen, or FusionCompute). In some architectures, the host OS and hypervisor may coexist, but they arenot the same concept.

Therefore, the false statement isD.

In FusionCompute virtual networking, VMs in thesame network segment and same port groupshould be able to communicate normally.

OptionAis a possible cause. Host-based or VM-based firewalls may block traffic between virtual machines.

OptionCis also a possible cause.Security groupscan apply access control rules that isolate VMs, even within the same subnet.

OptionDis a possible cause. Faulty virtual NICs or driver issues can prevent network communication.

OptionBisnota possible cause. If both VM NICs are connected to thesame port group, they should be able to communicate, assuming no other restrictions exist.

Therefore, the correct answer isB.

FusionCompute uses aunified storage abstraction model. Regardless of whether the backend storage is SAN, NAS, local disks, or distributed storage, FusionComputeencapsulates storage resources into datastores.

This abstraction simplifies management and allows virtual machines to consume storage in a standardized manner. While statements A, B, and C describe correct individual concepts,D best represents the core architectural principleemphasized in HCIA documentation.

Therefore, the correct answer isD.

FusionCompute installation has clear host hardware and configuration requirements defined in the HCIA syllabus.

OptionAis true. The boot device must match the installation location of the host operating system to ensure system stability.

OptionCis true.CPU virtualization must be enabledin the BIOS (Intel VT-x or AMD-V). If not enabled, the host cannot run virtual machines, which is a mandatory prerequisite.

OptionDis true. FusionComputecan be installed with a single network interface, although this is not recommended for production environments. Multiple NICs are preferred for traffic separation and high availability.

OptionBis false. The host where theVRM is deployed has higher disk requirementsthan ordinary compute nodes because it runs management services, databases, and logs. Therefore, its disk requirements arenot the sameas other compute nodes.

Thus, the false statement isB.
