NEW QUESTION # 29
What are the topologies of a Fibre Channel (FC) network? (Select all that apply)
Answer: A,B,C
Explanation:
According to Huawei's storage networking guides, Fibre Channel (FC) supports three primary physical topologies to facilitate communication between servers (initiators) and storage arrays (targets).
Point-to-point (Option C): This is the simplest topology where two nodes are directly connected. It provides dedicated bandwidth but lacks scalability.
Arbitrated loop (FC-AL) (Option D): In this setup, devices are connected in a loop shared by all nodes. While more scalable than point-to-point, only one pair of nodes can communicate at a time, leading to performance bottlenecks as more devices are added.
Fabric (FC-SW) (Option A): This is the most common enterprise topology, utilizing FC switches. It allows many-to-many communication, providing high scalability, redundancy, and independent bandwidth for each connection.
"Bus" (Option B) is a topology associated with older Ethernet or SCSI standards and is not a recognized topology in Fibre Channel networking. Huawei OceanStor Dorado and Hybrid systems primarily utilize the Fabric topology for large-scale data center deployments to ensure maximum availability and performance through redundant switch fabrics.
NEW QUESTION # 30
Which of the following basic elements are contained in an object? (Select all that apply)
Answer: A,B,C,D
Explanation:
Unlike traditional file storage which uses a hierarchical tree structure, Huawei Object Storage utilizes a flat structure where each "object" is a self-contained unit of data. According to the documentation, an object consists of four fundamental components:
Data (Option D): The actual content of the file (e.g., a photo, video, or document).
System Metadata (Option C): These are fixed attributes managed by the storage system, such as file size, creation date, last modified time, and HTTP content type.
Customized Metadata (Option B): A unique advantage of object storage is the ability to attach user-defined tags or labels to an object (e.g., "Patient_ID: 12345" or "Department: Radiology"). This allows for advanced data indexing and searching without opening the file itself.
Object Identifier (OID) (Option A): This is the unique key or "Address" used to retrieve the object. In a flat namespace, the OID ensures that every piece of data can be located instantly without traversing a complex directory path.
NEW QUESTION # 31
OceanStor Dorado all-flash storage can interconnect with OceanStor hybrid flash storage through asynchronous replication.
Answer: A
Explanation:
Huawei's OceanStor Dorado all-flash storage systems can interconnect with OceanStor hybrid flash storage systems through asynchronous replication. This capability allows for efficient data replication and disaster recovery between different types of storage systems.
NEW QUESTION # 32
Which statements about RAID of OceanStor Dorado are correct?
Answer: A,C,D
Explanation:
OceanStor Dorado uses Huawei RAID 2.0+ and advanced all-flash reliability technologies to improve data protection. Option A is correct because RAID-TP provides triple-parity protection and can tolerate the simultaneous failure of three disks. Option B is also correct because HyperZoom dynamically adjusts RAID member composition after disk failures, helping the system maintain redundancy instead of remaining in a degraded state longer than necessary. Option D is correct because Dorado supports data distribution across disk enclosures, allowing the system to tolerate enclosure-level failures when properly configured. Option C is incorrect because Dorado does not rely on traditional independent hot spare disks. Instead, spare capacity is distributed across the storage pool, enabling faster reconstruction and avoiding the bottlenecks associated with dedicated hot spares.
Therefore, A, B, and D are correct.
NEW QUESTION # 33
SCSI applies to SAN storage with HDDs, and NVMe applies to all-flash SAN storage.
Answer: A
Explanation:
This statement reflects the architectural evolution of Huawei OceanStor systems. The Small Computer System Interface (SCSI) protocol was designed decades ago for mechanical drives (HDDs). It uses a single command queue with a depth of 32 commands, which was sufficient for the physical limitations of rotating platters and moving heads.
In contrast, Non-Volatile Memory express (NVMe) was designed specifically for flash media. It replaces the legacy SCSI stack to eliminate bottlenecks. NVMe supports up to 64,000 queues, each with 64,000 commands, allowing for massive parallelism. Huawei OceanStor Dorado (All-Flash) systems utilize End-to-End NVMe (from the SSD to the controller, and from the controller to the host via NVMe-oF) to achieve microsecond-level latency. While modern flash arrays can still use SCSI (via FC or iSCSI) for compatibility, the full performance potential of an all-flash array is only realized through NVMe. Therefore, in modern storage design, SCSI is the legacy standard for HDDs/Hybrid arrays, while NVMe is the optimized standard for All-Flash arrays.
