NEW QUESTION # 38
Which of the following domain controller systems is supported by the SMB protocol?
Answer: A
Explanation:
The SMB (Server Message Block) protocol, which is primarily used for Windows-based file sharing, relies on a centralized authentication and authorization mechanism to manage permissions in an enterprise environment. In Huawei OceanStor NAS documentation, Active Directory (AD) is the primary domain controller system supported for the SMB protocol.
When a Huawei storage system joins an Active Directory domain, it can authenticate users and groups defined in the AD, allowing for seamless integration with Windows environments. While LDAP (Option A) and NIS (Option B) are supported by Huawei NAS for the NFS protocol (typically used in Linux/Unix environments), the SMB protocol is inherently designed to work with the Kerberos and NTLM authentication provided by Microsoft's Active Directory. This ensures that NTFS-style ACLs (Access Control Lists) can be properly mapped and enforced across the network.
NEW QUESTION # 39
Which are advantages of SAN storage? (Choose all that apply.)
Answer: A,B,C,D
Explanation:
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.
NEW QUESTION # 40
Which of the following OceanProtect features greatly improves backup performance and reduces backup time? (Select all that apply)
Answer: A,B
Explanation:
Huawei OceanProtect incorporates specialized algorithms to achieve industry-leading backup and recovery speeds. Source deduplication (Option A) is a primary performance driver because it filters out redundant data at the source, ensuring that only new data blocks are transmitted, which directly reduces the time required to complete a backup job.
Adaptive data locality rearrangement (Option D) is a unique feature that optimizes how data is written to and read from the physical disks within the OceanProtect array. During the backup process, the system calculates data dispersion in real-time and arranges data blocks on the disks to ensure they are stored sequentially. This is critical because it allows for high-speed sequential reads during data recovery, significantly improving the performance of HDDs which typically struggle with random I/O. While media deduplication (Option B) and secure snapshots (Option C) are essential for storage efficiency and security, they are not the primary features credited with the raw performance "leap" in backup and recovery speed.
NEW QUESTION # 41
How many faulty nodes can OceanStor Pacific tolerate at most?
Answer: C
Explanation:
According to the Huawei OceanStor Pacific series data sheet and reliability manuals, the system utilizes Elastic Erasure Coding (EC) for data redundancy protection. This technology is more efficient than traditional RAID and allows for higher levels of tolerance in a distributed environment.
Specifically, a single OceanStor Pacific storage system can be configured to tolerate the simultaneous failure of up to four nodes (or four cabinets in a multi-cabinet deployment) without data loss or service interruption. When a node fails, the system automatically triggers a background reconstruction process to restore redundancy using the remaining healthy nodes. The flexibility of dynamic EC ratios (N+M) allows the system to adjust to these faults while maintaining optimal space utilization and reliability.
NEW QUESTION # 42
What kind of data flows is supported by SmartMobility of OceanStor Dorado?
Answer: B,C
Explanation:
SmartMobility in OceanStor Dorado focuses on supporting SAN and NAS environments, optimizing data migration and access within these protocols, while HDFS and Object storage flows are not typically included in its supported data flows.
SmartMobility of OceanStor Dorado primarily supports SAN and NAS data flows rather than covering all types listed. HDFS and Object storage flows are not directly supported by SmartMobility.
