Pass the Huawei HCIA Storage H13-611_V4.5 Questions and answers with CertsForce

A failover group is a combination of ports that are used for IP address failover in a storage system, and IP address failover ensures service continuity and improves the reliability of paths for accessing file systems. IP address failover applies to all storage network architectures, not just IP SAN. Fallback means that the standby port takes over services when the active port fails, and then the active port takes over services again after it recovers.

Deduplication is a data reduction technology that compresses large-size data blocks to reduce the physical storage capacity for storing data, thereby meeting increasing storage capacity requirements. Deduplication can greatly reduce the amount of storage needed to store data, and can also increase the efficiency of data access.

When choosing between different types of SSDs, the main factor to consider is the trade-off between cost and reliability. SLC (Single-Level Cell) SSDs are the most reliable and have the longest lifespan, but they are also the most expensive. TLC (Triple-Level Cell) SSDs are less reliable than SLC SSDs, but they are also less expensive. MLC (Multi-Level Cell) SSDs are a good balance between cost and reliability, they are more affordable than SLC SSDs and more reliable than TLC SSDs.

The main functions of the business continuity solution are to minimize the impact on the business service, ensure zero data loss and zero service interruption, and improve the utilization rate of the disaster recovery equipment. Predicting the disaster occurrence accurately is not a function of the business continuity solution.

When using CLI to configure Huawei hybrid flash storage, the operations involved in creating storage space include creating a storage pool, creating a LUN, and creating a LUN group. Creating a host is not involved in creating storage space.

A snapshot is a point-in-time copy of the source data that serves as a data backup accessible to hosts. Snapshots are commonly used to recover data in case of accidental deletion or corruption, or to allow multiple users to access the same data without interference with each other.

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.

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.

RAID 0 is a data striping technique that involves distributing data across two or more disks, which allows for increased performance and capacity. RAID 0 does not provide redundancy, and if any of the disks in the RAID group fail, the data will be lost. RAID 5 and RAID 6 are both data striping techniques, but they also provide redundancy, which means that the data is still recoverable even if one or more disks in the RAID group fail. RAID 1 is a data mirroring technique, which involves writing the same data to two disks, and does not use data striping.
