The BCManager architecture shows eReplication Server components associated with the production and DR environments, while the one-click fault-recovery workflow explicitly performs recovery by setting storage resources at the DR site to writable, mapping LUNs, configuring storage, and recovering services.

The statement is therefore TRUE. In a dual-eReplication-server remote DR deployment, management operations can normally be initiated through either management endpoint because the servers coordinate DR configuration and protection information. Fault recovery is different because the production environment is assumed to be unavailable or impaired. Recovery must consequently be executed from the DR-side management environment that remains accessible and can coordinate activation of DR resources.

The fault-recovery workflow reflects this requirement: secondary resource consistency is checked, DR storage is made writable, LUNs are mapped, the storage configuration is completed, and services are recovered at the DR site.

Huawei also recommends placing DR management capabilities where they remain available when production infrastructure fails, reinforcing the design objective of independent DR-side recovery control.

The HCIE Lab Guide states: “For bond ports of the Bond4 type on the host, the dynamic LACP mode must be configured for the bond ports on the switch.”

Therefore, the correct selection is B. Mode 4.

Mode 4 corresponds to the Bond4/LACP-based link-aggregation design used where multiple physical Ethernet links operate as one logical connection. When front-end switches are deployed as an M-LAG pair, link aggregation can span the two physical switches while presenting a single logical aggregation relationship toward the connected system.

This design is specifically appropriate for switch-port and link redundancy. If one member link or one associated switch-side port fails, the remaining member links continue carrying traffic without requiring the logical storage interface to be taken offline. It also enables bandwidth aggregation under normal conditions.

The Lab Guide ' s networking principles distinguish this from simple standalone interfaces and explicitly require dynamic LACP on the switch side when Bond4 is used. That requirement aligns with an M-LAG front-end design where resilient link aggregation is required across redundant switches.

Huawei ' s troubleshooting procedure states: “Cause 2: The link is abnormal.” It then instructs the engineer to check DeviceManager and determine whether the Fibre Channel or iSCSI port connected to the application server has a running status of “Link down.” If it does, the engineer must troubleshoot the corresponding FC or iSCSI link failure. This distinction is important. A Link down status represents a lower-layer connectivity condition involving the physical/interface link, switch path, cabling, peer port, or interface state. IP addressing belongs to the Layer-3 service configuration. An incorrect logical-port IP address or host service IP can prevent IP communication, iSCSI login, or service connectivity, but it does not by itself force an Ethernet physical interface into the Link-down state.

The training material separately treats IP address information as networking configuration information for iSCSI environments, rather than as the definition of a Link-down condition. Therefore, the statement incorrectly attributes the observed physical/link-layer status to IP configuration.

Huawei states that “HyperLock is also called the Write Once Read Many (WORM) feature” and that it protects the integrity, confidentiality, and accessibility of stored data. The course further explains that with WORM, data can be written once and then cannot be rewritten, modified, deleted, or renamed during the protection period.

Therefore, HyperLock is the critical function for this requirement. Encryption protects data confidentiality, but encrypted backup data could still be deleted or maliciously overwritten if the attacker obtains sufficient privileges. Network isolation and stronger authentication reduce the attack surface, but neither provides the immutable-copy property specified in the scenario.

HyperLock establishes that immutable recovery layer. Even if ransomware compromises production data or attempts to destroy backup copies, properly locked backup data remains protected against unauthorized alteration or deletion throughout the retention period. This is precisely the security property needed when backup data must form the final recovery boundary against ransomware.

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.
