Huawei HCIA-Data Center 認定 H13-411 試験問題:

1. Server virtualization abstracts physical resources of a server into logical resources, changing one server into multiple virtual servers isolated from each other and eliminating physical restrictions.
Which of the following are in the server virtualization range? (Multiple Choice)

A) Disk virtualization
B) Memory virtualization
C) I/O virtualization
D) CPU virtualization

2. Block storage is a mode of storing data by block, and a block refers to the sector group on the underlying disk.
Which of the following statements regarding block storage is true?

A) Storage devices are cost-effective.
B) Block storage can meet the requirement of a system containing thousands of CPUs.
C) Block storage can provide high-performance random I/O and data throughput.
D) Block storage has good scalability and manageability.

3. Which of the following statements regarding the high reliability of Huawei OceanStor V3 are true? (Multiple Choice)

A) Huawei OceanStor V3 provides the backup battery unit (BBU) module, which can provide power to the controller enclosure in the event of a power failure. This ensures that Huawei OceanStor V3 is able to write cache data into the built-in disks on the controller to prevent data loss.
B) Huawei OceanStor V3 uses RAID 2.0+ (underlying virtualization technology) to automatically balance loads among disks.
C) Huawei OceanStor V3 uses the disk precopy technology. By routinely checking the risk status, Huawei OceanStor V3 proactively migrates the data on a disk when detecting a fault risk on the disk, effectively reducing the data loss risks.
D) The Huawei OceanStor V3 components use the 1+ 1 redundancy design and work inactive-active mode.

4. Which of the following statements regarding Huawei AR series routers is false?

A) Huawei AR series routers are the next-generation routing and gateway devices that provide routing, switching, wireless, voice, and security functions.
B) Huawei AR series routers can provide dual up links, ensuring network service reliability.
C) Huawei AR series routers provide various value-added services, including DHCP, NAT, domain name system (DNS), and accounting services.
D) Huawei AR series routers do not support one-stop deployment, but provide remote centralized management on customer-premises equipment (CPE), significantly reducing the maintenance costs of enterprise users and improving the maintenance efficiency.

5. Which of the following statements regarding the host group in the FusionSphere OpenStack OM is false?

A) After a host group is created, the host resources in the host group can be used to created VMs.
B) Used and available resource quantities of a host group can be viewed in the host group list.
C) The tags of the host group and flavors can be configured. During VM creation, the host group to be used to create VMs can be specified by selecting flavors.
D) A host is the node providing the computing capability in the OpenStack instance, and generally consists of one or more physical servers. The host runs the virtualization software to provide the VM service.
