Curious about Actual Huawei HCIP (H12-893_V1.0) Exam Questions?

Correct : D

To identify the false statement, we evaluate each option based on standard M-LAG documentation, such as Huawei's and Arista's guidelines, which are commonly referenced in HCIP-Data Center Network training.

Option A: In loose mode, if Type 1 configurations of the two M-LAG member devices are inconsistent, the member interface on the M-LAG backup device is in Error-Down state and an alarm is generated, indicating that Type 1 configurations on the two devices are inconsistent.

Evaluation: This statement is true. In loose mode, inconsistencies in Type 1 (key) configurations are still critical, as they can affect M-LAG operation. According to Huawei M-LAG Configuration Guide, when Type 1 configurations are inconsistent in loose mode, the system may place the member interface on the backup device into an Error-Down state and generate an alarm to alert administrators. This ensures that critical issues are flagged, even in loose mode, to prevent loops or packet loss.

Conclusion: True.

Option B: If Type 1 configurations of the two M-LAG member devices are inconsistent, certain problems may occur, such as loops and long-period packet loss when the status is normal.

Evaluation: This statement is true. Type 1 configurations are essential for M-LAG operation, and inconsistencies can lead to severe network issues. For example, mismatched LACP settings or VLAN mappings can create loops or cause packet loss, as noted in Arista M-LAG Documentation. These problems can persist even when the system appears normal, making consistency checks critical for troubleshooting and O&M.

Conclusion: True.

Option C: If Type 2 configurations of the two M-LAG member devices are inconsistent, the M-LAG running status may be abnormal. Compared with Type 1 configuration problems, Type 2 configuration problems are more likely to be detected and have less impact on the network.

Evaluation: This statement is true. Type 2 (common) configurations, such as QoS or STP settings, are less critical but can still affect network performance. According to Huawei M-LAG Best Practices, Type 2 inconsistencies are often detected during consistency checks but have a lower impact on M-LAG operation compared to Type 1 issues. They are also more likely to be flagged during monitoring, as they are less severe and easier to resolve.

Conclusion: True.

Option D: If Type 2 configurations of the two M-LAG member devices are inconsistent, an alarm that indicates key and common configuration inconsistencies is generated.

Evaluation: This statement is false. While Type 2 (common) configuration inconsistencies are detected during consistency checks, they do not typically trigger alarms, especially alarms that specifically indicate both key and common configuration inconsistencies. According to Huawei M-LAG Configuration Guide and Arista M-LAG Documentation, Type 2 inconsistencies may be logged or reported in system logs but are not severe enough to generate critical alarms unless they significantly impact network operation. Alarms are more commonly associated with Type 1 (key) configuration inconsistencies, as they pose a higher risk to M-LAG functionality.

Conclusion: False.

Correct : A, D

In Huawei's M-LAG (Multi-Chassis Link Aggregation), the heartbeat link (or peer-link) ensures communication between member devices. A fault in this link can impact M-LAG operation. Let's evaluate each statement:

A . The fault that two master devices exist cannot be detected in the case of a peer-link fault: This is false. A peer-link fault can be detected, and mechanisms like dual-master detection (e.g., via Inter-Chassis Communication Link or ICC) can identify if both devices assume master roles, triggering corrective actions. FALSE.

B . An alarm is triggered: This is true. A peer-link fault generates an alarm to notify administrators, as it's a critical failure in M-LAG operation, per Huawei's fault management system. TRUE.

C . The fault protection mechanism is triggered: This is true. Huawei M-LAG includes protection mechanisms (e.g., failover to backup links or shutdown of conflicting interfaces) to mitigate peer-link faults and maintain service continuity. TRUE.

D . Services are affected: This is false. With proper configuration (e.g., redundant links or fast failover), services should not be affected by a peer-link fault, as M-LAG is designed for high availability. Impact depends on redundancy, but the design goal is uninterrupted service. FALSE.

Thus, A and D are false statements because dual-master faults can be detected, and services are not necessarily affected with adequate redundancy.

Correct : A, B

The tenant service model in Huawei's data center networks (e.g., CloudFabric with SDN) organizes resources for multi-tenancy. Let's evaluate each statement:

A . A tenant can apply for independent compute, storage, and network resources: This is true. Tenants in a multi-tenant environment can request isolated compute (VMs), storage (volumes), and network (VLANs/VXLAN VNIs) resources, a core feature of Huawei's tenant isolation model. TRUE.

B . One logical router is mapped to one VRF: This is true. A Virtual Routing and Forwarding (VRF) instance is associated with a logical router to provide isolated Layer 3 routing for a tenant, a standard practice in Huawei's network virtualization. TRUE.

C . An EPG can have only one subnet: This is false. An Endpoint Group (EPG) in Huawei's ACI-like models can span multiple subnets, grouping endpoints (e.g., VMs) based on policies, not limited to a single subnet. FALSE.

D . A subnet supports the access of only one VM: This is false. A subnet can support multiple VMs, as it defines an IP address range for a network segment, not a one-to-one VM mapping. FALSE.

Thus, A and B are true statements about the tenant service model.

Correct : A, B, C, D

Microsegmentation in Huawei's data center networks (e.g., CloudFabric with SDN) divides Endpoint Groups (EPGs) to enforce fine-grained security policies. EPGs group endpoints (e.g., VMs) based on attributes. Let's evaluate each option:

A . Operating system: This is true. The OS type (e.g., Linux, Windows) can be used to segment EPGs, enabling policy enforcement based on OS-specific security needs. TRUE.

B . VM name: This is true. VM names can be used as identifiers for microsegmentation, allowing policies to target specific VMs. TRUE.

C . IP address: This is true. IP addresses are commonly used to define EPG boundaries, especially for network-based segmentation. TRUE.

D . MAC address: This is true. MAC addresses can segment EPGs, particularly for Layer 2-based policies or device-specific isolation. TRUE.

All options A, B, C, and D are valid conditions for microsegmentation to divide EPGs in Huawei's implementation.

Correct : A, B, C, D

Huawei's CloudFabric solution provides an SDN-based framework for data center network management, supporting automation across the network lifecycle. Let's evaluate each phase:

A . Planning and construction: This is true. CloudFabric automates network design, resource allocation, and deployment during the planning and construction phase using tools like iMaster NCE. TRUE.

B . Service provisioning: This is true. Automated service orchestration (e.g., VXLAN tunnel setup, tenant configuration) is a key feature during provisioning. TRUE.

C . O&M and monitoring: This is true. CloudFabric offers real-time monitoring, fault detection, and performance optimization through centralized management. TRUE.

D . Change optimization: This is true. The solution supports automated upgrades, policy adjustments, and optimization based on analytics, covering the change management phase. TRUE.

All phases A, B, C, and D are supported by CloudFabric's full-lifecycle automation.
