Free Practice Questions for Huawei H13-611_V4.5 Exam

Zoning is a technology that segregates the nodes in the SAN fabric into multiple networks and allows access control of the members. Subnet, VLAN, and Quarantine are all related to network security, but they are not specifically used in a SAN fabric.

The correct answers are B. Better environmental adaptability, C. Faster read/write speed for random access, and D. Longer service life. SSDs (solid-state drives) offer several advantages over HDDs (hard disk drives), including better environmental adaptability, faster read/write speed for random access, lower power consumption, and a longer service life. SSDs also tend to have smaller form factors, making them ideal for many mobile applications. However, HDDs typically offer larger capacity than SSDs.

Solid-state drives (SSDs) are a type of data storage device that have several advantages over hard disk drives (HDDs).

Better environmental adaptability: SSDs are not affected by temperature, humidity, or altitude changes, and they are more resistant to shock and vibration than HDDs.

Faster read/write speed for random access: SSDs have no moving parts, which means that data can be read and written much faster than on HDDs, especially for random access to small files.

Longer service life: SSDs have no moving parts, so they are less likely to fail due to mechanical issues. They also have a higher maximum read/write cycle than HDDs, which means that they can handle more write operations over their lifetime.

Larger capacity: SSDs are not always have larger capacity than HDDs, it depends on the specific model and brand.

The most widely used Fibre Channel (FC) topology is the FC Switched Network. This topology uses a centrally managed switch to create a network of connected devices, allowing them to communicate with each other. This type of topology is highly scalable, as additional devices can be added to the network without any reconfiguration. It also provides higher performance than other topologies, as it can route data more quickly and efficiently.

Resolution: Only thin LUN can enable deduplication.

NAS (Network Attached Storage) is a type of storage system that provides file sharing services over a network. NAS systems use standard network protocols such as NFS (Network File System) and CIFS (Common Internet File System) to provide file-level access to data, allowing multiple users to access and share files stored on the NAS device. This makes it an effective solution for storing, sharing, and managing large amounts of data within an organization. Additionally, modern NAS systems can offer features such as data replication, snapshots, and data protection, which adds to the functionality of the storage solution.

In order to add additional controllers to an existing HUAWEI OceanStor system, a FC (Fibre Channel) or iSCSI (Internet Small Computer System Interface) Host Bus Adapter (HBA) is required. The HBA connects the controller to the storage devices, and it is required to add additional controllers to the system. The HBA provides the interface between the controller and the storage devices, and it allows the controller to communicate with the storage devices over the FC or iSCSI protocol. Other options such as SAS cabling, 56 Gb Infiniband module, and Smart I/O card are also important components in storage systems, but they are not directly related to adding additional controllers to an existing HUAWEI OceanStor system.

In active-standby mode, only one controller works at a time and if one controller is faulty, services are not affected. In active-active mode, both controllers are active and the service failover is more efficient than in active-standby mode.

A, C, and D are all true statements about the functions of HyperClone. HyperClone allows you to back up data from a source LUN, and when the source LUN fails, service data can be recovered from any point in time before the fault occurred . Additionally, if a logical fault occurs on the source LUN, data can be reversely synchronized from the target LUN to the source LUN to recover services on the source LUN. Finally, multiple target LUNs can be created through HyperClone to provide the service data on the source LUN for multiple applications.

A disk domain is a collection of physical disks of the same type and speed. If a disk domain has multiple disk types, it is not necessary that the storage pools within that disk domain have multiple disk types as well. Storage pools are a collection of physical disks within a disk domain that are grouped together to provide storage capacity. The storage pools can be created with different RAID levels and disk types, so it is possible to have a disk domain with multiple disk types and still have storage pools with only one disk type. It depends on how the administrator wants to configure the storage pool and how the storage is used.
