Huawei HCIP-Data Center Network V1.0 H12-893_V1.0 Prüfungsfragen mit Lösungen (Q20-Q25):

20. Frage
Which of the following protocols is used to back up session tables between the active and standby firewalls in the hot standby scenario?

A. VRRP
B. M-LAG
C. BFD
D. HRP

Antwort: D

Begründung:
In a hot standby scenario, firewalls (e.g., Huawei USG series) maintain high availability by synchronizing session tables between active and standby devices to ensure seamless failover. Let's evaluate each protocol:
A . M-LAG (Multi-Chassis Link Aggregation): M-LAG is a link aggregation technology for switches, not designed for session table backup between firewalls. Incorrect.
B . VRRP (Virtual Router Redundancy Protocol): VRRP provides gateway redundancy by electing a master router, but it does not handle session table synchronization between firewalls. Incorrect.
C . BFD (Bidirectional Forwarding Detection): BFD is a fast failure detection protocol used with routing protocols, not for session table backup. Incorrect.
D . HRP (Hot Standby Redundancy Protocol): HRP is Huawei's proprietary protocol specifically designed for firewall hot standby scenarios. It synchronizes session tables, configuration data, and status information between active and standby firewalls to ensure stateful failover. Correct.
Thus, the answer is D (HRP).

21. Frage
A Huawei data center uses distributed gateways on leaf switches. Which advantage does this design primarily provide compared with a centralized gateway architecture?

A. Elimination of BGP
B. Longer forwarding paths
C. Higher multicast dependency
D. Reduced east-west traffic latency

Antwort: D

Begründung:
Distributed gateways allow local routing at the access layer, reducing unnecessary traffic through centralized devices. This minimizes latency for east-west traffic and improves scalability. BGP remains important for EVPN control-plane operations.

22. Frage
Which of the following are advantages of iMaster NCE-FabricInsight's telemetry-based performance metric collection? (Select All that Apply)

A. One-off subscription and continuous data push
B. Quasi-real-time data collection
C. Efficient transmission
D. Intelligent data analysis and automated troubleshooting

Antwort: A,B,C

Begründung:
iMaster NCE-FabricInsight uses telemetry for performance metric collection, offering advanced monitoring in Huawei's CloudFabric Solution. Let's evaluate each option:
A . Efficient transmission: This is true. Telemetry uses streaming data (e.g., gRPC) to reduce overhead compared to traditional polling, enabling efficient transmission of metrics. TRUE.
B . Quasi-real-time data collection: This is true. Telemetry provides near-real-time data (e.g., sub-second updates), improving responsiveness over periodic SNMP polling. TRUE.
C . Intelligent data analysis and automated troubleshooting: This is false. While FabricInsight performs intelligent analysis, automated troubleshooting is a feature of the broader iMaster NCE platform, not specifically a telemetry advantage. Telemetry enables data collection, not the automation itself. FALSE.
D . One-off subscription and continuous data push: This is true. Telemetry operates on a subscription model where a one-time setup leads to continuous data push from devices, reducing manual intervention. TRUE.
Thus, A, B, and D are advantages of telemetry-based performance metric collection.

23. Frage
A company plans to eliminate STP loops while supporting active forwarding across multiple Layer
2 paths in a data center. Which architecture best satisfies this requirement through Layer 3 forwarding and VXLAN encapsulation?

A. Single-core aggregation
B. Ring topology
C. Spine-leaf architecture
D. Traditional VLAN campus

Antwort: C

Begründung:
The spine-leaf architecture provides predictable latency, ECMP forwarding, and Layer 3 underlay connectivity. VXLAN overlays eliminate traditional Layer 2 loop concerns and avoid dependence on STP for traffic forwarding between servers.

24. Frage
When an SDN controller cluster is deployed in Huawei CloudFabric Solution, which of the following network planes are divided based on carried services? (Select All that Apply)

A. Southbound service plane
B. Internal communication plane
C. Northbound management plane
D. BGP microservice plane

Antwort: A,B,C

Begründung:
In Huawei's CloudFabric Solution, the iMaster NCE-Fabric SDN controller cluster separates network planes based on carried services to ensure scalability and security. Let's evaluate each option:
A . BGP microservice plane: This is not a standard plane in Huawei's SDN architecture. BGP is used in the underlay/overlay but not defined as a separate microservice plane for the controller. FALSE.
B . Southbound service plane: This is true. The southbound plane carries configuration and control data to network devices (e.g., via NETCONF, BGP-EVPN), a critical service plane in SDN. TRUE.
C . Northbound management plane: This is true. The northbound plane provides APIs for management applications and orchestration (e.g., OpenStack integration), handling service requests. TRUE.
D . Internal communication plane: This is true. This plane facilitates communication between controller cluster nodes for synchronization and high availability. TRUE.
Thus, B (Southbound service plane), C (Northbound management plane), and D (Internal communication plane) are the network planes divided based on carried services.
