質問 # 64
Incremental backup requires the previous full backup and incremental backup to fully restore dat a. Data reconstruction is slower than full backup, and the restoration is long.
- A. FALSE
- B. TRUE
正解：B
解説：
This statement accurately reflects the technical characteristics of traditional incremental backup strategies found in Huawei data protection guides. An Incremental Backup only copies the data that has changed since the last backup (whether that was a full or an incremental backup).
While this saves significant time and storage space during the backup window, it adds complexity during restoration. To fully restore a system to its latest state, the administrator must first restore the last Full Backup and then sequentially apply every subsequent Incremental Backup in the correct order. If any single incremental tape or file in the chain is missing or corrupted, the restoration cannot be completed beyond that point. Because the system must process multiple data sets to reconstruct the final image, the total recovery time (RTO) is indeed longer and the process is slower compared to restoring from a single Full Backup.
質問 # 65
What protocols does the DAS interface support? (Choose all that apply.)
- A. Fibre Channel
- B. SAS
- C. iSCSI
- D. InfiniBand
正解：A、B
解説：
Fibre Channel and SAS are protocols commonly supported by DAS (Direct-Attached Storage) interfaces. Fibre Channel provides high-speed connectivity, and SAS (Serial Attached SCSI) is widely used for connecting servers to directly attached storage devices. DAS does not typically support InfiniBand or iSCSI, as these are more associated with SAN or high-performance computing environments.

High scalability allows easy expansion to accommodate growing data needs.
High resource utilization enables efficient sharing of storage resources across multiple servers.
High reliability is achieved through redundancy and data protection features.
High performance is provided by dedicated, high-speed connections for fast data access.
質問 # 67
Which statements about OceanStor Dorado reliability are correct? (Select all that apply)
- A. RAID-TP tolerates the failure of three SSDs. The full-mesh architecture tolerates the failure of seven out of eight controllers.
- B. Disk enclosure failure can be tolerated through redundancy protection.
- C. Global wear leveling and anti-wear leveling are used for SSDs.
- D. SAN and NAS HyperMetro solutions are provided.
正解：A、B、C、D
解説：
The Huawei OceanStor Dorado series is engineered for 99.9999% availability using multiple layers of reliability. Option A is correct as RAID-TP (Triple Parity) is a unique Huawei feature that uses three parity chunks to tolerate the simultaneous failure of any three SSDs in a disk group. Furthermore, the SmartMatrix full-mesh architecture in high-end models allows the system to remain operational even if seven out of eight controllers in a controller enclosure fail, ensuring extreme service continuity.
Option B is correct because Huawei utilizes Global Wear Leveling to distribute writes across all SSDs to extend their lifespan, and Anti-Wear Leveling to prevent multiple SSDs from reaching their end-of-life simultaneously, which avoids multi-disk failure risks. Option C is correct as the system supports HyperMetro (Active-Active) for both block (SAN) and file (NAS) services, providing zero RTO and RPO across sites. Option D is correct because Dorado supports high-reliability disk enclosure connection technologies; in a multi-enclosure setup, the system can tolerate the failure of an entire disk enclosure without data loss by using intelligent data distribution across different enclosures.

正解：B
質問 # 75
When RAID 5 is configured for the new-gen OceanStor hybrid storage, how many write penalties are generated in one full-stripe write operation?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
In Huawei OceanStor storage systems utilizing RAID 2.0+ and the SmartMatrix architecture, the "write penalty" associated with traditional RAID is mitigated through Full-Stripe Writes. In a partial write (where only some data in a stripe is updated), a RAID 5 setup usually suffers a write penalty of 4 (Reading old data, reading old parity, writing new data, writing new parity).
However, Huawei's controllers utilize a large cache to aggregate incoming data. When enough data is collected to fill an entire stripe (e.g., 8 data chunks plus 1 parity chunk in an 8+1 RAID 5 setup), the system performs a Full-Stripe Write. In this scenario, the system calculates the parity in the CPU/cache and writes the entire stripe to the disks at once. Since no old data or old parity needs to be read from the physical disks before writing, the disk-level write penalty is 0. This significantly enhances the write performance of hybrid arrays, especially those using mechanical HDDs which are highly sensitive to the latency of extra read/write operations.

質問 # 80
Thin provisioning allocates storage space on demand, improving resource utilization.
- A. FALSE
- B. TRUE
正解：B
解説：
Huawei's SmartThin technology is a thin provisioning feature that allows storage administrators to allocate more logical capacity to servers than is physically available in the storage pool. Traditionally, "thick provisioning" reserves the entire capacity of a LUN the moment it is created, leading to significant "stranded" or wasted space if the application does not immediately use it.
With SmartThin, the storage system only consumes physical blocks when data is actually written to the disk. This "on-demand" allocation ensures that physical resources are shared across multiple LUNs more efficiently. For example, a 10 TB LUN might be presented to a database, but if the database only contains 2 TB of data, only 2 TB of physical space is consumed. This significantly improves the Storage Resource Utilization Rate and reduces the Total Cost of Ownership (TCO) by delaying the need to purchase additional physical disks until the actual consumed capacity approaches the physical limits of the array.
質問 # 81
In SmartMulti-Tenant, a vStore is managed by only one tenant administrator, and vStDres are isolated from each other.
- A. FALSE
- B. TRUE
正解：B
質問 # 82
Which of the following is the correct sequence of time required for restoring data using different backup types?
- A. Full backup > Incremental backup > Differential backup
- B. Full backup > Differential backup > Incremental backup
- C. Incremental backup > Differential backup > Full backup
- D. Differential backup > Full backup > Incremental backup
正解：C
解説：
Incremental backup requires the previous full backup plus all incremental backups, making it the slowest to restore. Differential backup requires the previous full backup plus a single differential backup, making it faster than incremental but slower than full. Full backup restores are the fastest.
質問 # 83
Which of the following statements about NFS is incorrect?
- A. If both security and small file processing performance matter, NFSv4.1 is recommended.
- B. NFSv3 has relatively high small file processing performance but weak security.
- C. NFSv4.1 greatly improves small file processing performance over NFSv4.
- D. NFSv4 greatly enhances security and enables small file processing performance comparable to NFSv3.
正解：C
解説：
NFSv4.1 mainly enhances features like session trunking and parallelism but does not significantly improve small file processing performance over NFSv4. Its main improvements are in scalability and reliability, not small file performance.

質問 # 87
When user A modifies a file in the NAS system, which of the following operations can user B perform on the file?
- A. File renaming
- B. File modification
- C. File reading
- D. File deletion
正解：C
解説：
In Huawei OceanStor NAS systems, data consistency and integrity are maintained through a mechanism known as File Locking. When User A opens a file for modification (a write operation), the storage system applies a "Write Lock" or an "Exclusive Lock" to that specific file. This lock prevents other users from performing any actions that would alter the file's metadata or content, as these concurrent changes would lead to data corruption or "lost updates".
Consequently, File deletion (Option A), File modification (Option C), and File renaming (Option D) are all blocked because they require write-level access or changes to the file system's directory structure that conflict with the active lock held by User A. However, File reading (Option B) is generally permitted unless User A has specifically requested an exclusive lock that bars all access. In standard CIFS/SMB and NFS configurations used by Huawei, multiple users can read a file while one user is writing, ensuring that information remains accessible without compromising the integrity of the file being updated.
