OceanProtect ' s architecture explicitly includes a “Ransomware protection solution (encryption/decryption, WORM, ransomware detection, and secure transmission).” The course also states that ransomware protection protects copies and provides anti-tampering through the read-only attribute of WORM.

Therefore, all four mechanisms contribute to the required defense.

WORM provides the immutable-copy foundation. Huawei explains that protected WORM files cannot be rewritten, modified, deleted, or renamed during their protection period. Abnormal behavior monitoring corresponds to ransomware-detection capabilities used to identify suspicious activity against protected copies. Multi-layer antivirus association provides an additional malware-detection barrier around file-oriented protection workflows.

Finally, access control limits who can administer, modify, or operate protection resources. OceanProtect implements role-based access control with predefined and customizable roles, reducing the attack surface for compromised or unauthorized accounts.

Together these controls provide detection, prevention, privilege restriction, and immutable recovery copies.

The correct selections are IPMI, RESTful, and Redfish.

Huawei describes DME as “the unified management software integrating software and hardware for data centers” and states that it controls, manages, and analyzes VMs, datastores, databases, servers, switches, and storage devices.

For API-oriented integration, RESTful is explicitly part of Huawei ' s DME architecture. The storage-management course states that the open southbound system manages storage, switch, and host resources through management protocols including RESTful.

IPMI and Redfish provide the hardware-management interfaces required when the management platform interacts with server/BMC infrastructure. Redfish supplies a modern REST-oriented hardware-management model, while IPMI provides established out-of-band platform-management functions.

Telnet is not selected. It is a legacy plaintext terminal protocol and is not an appropriate protocol for the hardware/API interconnection functions being tested in this DME management architecture.

Huawei identifies MigrationDirector for SAN as the dedicated migration tool for SAN storage migration. Before migration execution, the migration environment must be defined: the source storage must be identified, the relevant service host must be known, and the target storage/resources must be prepared.

The Lab Guide ' s workflow places Creating a Service Host, Configuring the Source Storage, and Preparing the Target Storage before the actual Data Migration phase. A SmartVirtualization migration lab follows the same structure: production/service-host preparation and target-storage preparation precede takeover and data migration.

This makes A, B, and C configuration/preparation activities.

Option D belongs later in migration execution. Huawei ' s migration delivery sequence explicitly places target-storage configuration and migration preparation before stopping services, taking over the source storage, recovering applications, and migrating data.

Therefore, service takeover is an implementation/cutover activity rather than information entered during migration-task configuration.

Huawei ' s LUN-discovery troubleshooting procedure explicitly lists “Cause 1: The storage pool is faulty” and “Cause 2: The link is abnormal.” For an abnormal link, DeviceManager is used to check whether the connected FC or iSCSI port reports Link down. The separate multipathing troubleshooting section states that multipathing malfunction generally leads to storage performance deterioration or failure to discover multiple paths. Typical causes include the multipathing software being blocked or the HBA driver having its own failover function. Therefore, the complete absence of multipathing software does not inherently prevent a Linux host from detecting a mapped LUN through an available single path. Multipathing primarily provides path aggregation, redundancy, failover, and load balancing.

By contrast, a faulty storage pool can make the LUN unavailable; incorrect FC zoning prevents the host initiator from reaching storage targets; and an actual physical or logical link fault prevents device discovery. Consequently, option A is the false statement.
