Huawei HCIP-Data Center Network V1.0 H12-893_V1.0 Prüfungsfragen mit Lösungen (Q44-Q49):

44. Frage
Which of the following statements is false about VM service traffic in the computing scenario?

Antwort: A

Begründung:
In Huawei's CloudFabric computing scenario, VM service traffic involves virtualized environments with VXLAN overlays and traditional VLANs. Let's evaluate each statement:
A). Traffic inside a fabric is VXLAN encapsulated: This is true. Within a CloudFabric network, VXLAN encapsulation is used to transport traffic across the fabric, enabling overlay networking for VMs.
TRUE.
B). Inter-VPC traffic must pass through the firewall: This is false. Inter-VPC (Virtual Private Cloud) traffic can be routed directly between VPCs using a gateway or router (e.g., with EVPN Type 5 routes) without necessarily passing through a firewall, depending on security policies. Firewalls are optional for inter-VPC traffic, not mandatory. FALSE.
C). Traffic between VAS devices and service leaf nodes is VLAN encapsulated: This is true.
Value- Added Services (VAS) devices (e.g., load balancers) often connect to service leaf nodes using VLAN encapsulation, especially in traditional or hybrid deployments. TRUE.
D). Traffic between vSwitches on virtual servers and server leaf nodes is VLAN encapsulated:
This is true. Traffic from virtual switches (vSwitches) on hypervisors to physical server leaf nodes typically uses VLAN encapsulation over the physical NICs, before VXLAN overlay if applicable.
TRUE.
Thus, B is the false statement because inter-VPC traffic does not always require a firewall.


45. Frage
In which of the following phases can CloudFabric implement full-lifecycle automatic network management and control? (Select All that Apply)

Antwort: A,B,C,D

Begründung:
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.


46. Frage
In Huawei CloudFabric Solution, OSPF or BGP can be used on the underlay network of a DC.

Antwort: A

Begründung:
In Huawei's CloudFabric Solution, the underlay network provides the physical infrastructure for VXLAN overlays. Both OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol) are supported routing protocols:
OSPF: Suitable for smaller to medium-sized DCNs, offering fast convergence and simplicity.
BGP: Preferred for large-scale DCNs, providing scalability and multi-tenancy support (e.g., EBGP for inter-AS or iBGP for intra-DC).
Huawei documentation confirms flexibility in choosing OSPF or BGP based on network size and requirements. The statement is TRUE (A).


47. Frage
Both M-LAG and stacking technologies can overcome the disadvantages of traditional DCNs. However, M-LAG is a better choice to ensure 24/7 service continuity.

Antwort: A

Begründung:
Traditional data center networks (DCNs) often suffer from single points of failure, limited scalability, and traffic bottlenecks. Both M-LAG and stacking address these issues, but their suitability for 24/7 service continuity differs.
M-LAG Benefits: M-LAG (Multi-Chassis Link Aggregation) on Huawei CE switches allows two devices to act as a single logical switch, providing active-active forwarding, high availability, and rapid failover (e.g., via peer-link synchronization). It supports non-stop service during device failures, making it ideal for 24/7 continuity.
Stacking Benefits: Stacking combines multiple switches into a single logical unit, sharing a control plane. While it improves scalability and simplifies management, a stack master failure can disrupt the entire stack unless redundancy is perfectly configured, potentially affecting service continuity.
Comparison: M-LAG's decentralized design and real-time synchronization offer better fault isolation and recovery compared to stacking, where a master switch failure impacts the stack. Huawei documentation highlights M-LAG's superiority for high-availability scenarios like 24/7 operations.
The statement is TRUE (A) because M-LAG is indeed a better choice than stacking for ensuring 24/7 service continuity due to its robust failover and redundancy features.


48. Frage
Which of the following issues can be identified by the health function of iMaster NCE-FabricInsight? (Select All that Apply)

Antwort: A,B,C,D

Begründung:
iMaster NCE-FabricInsight is Huawei's network assurance and analytics tool, integrated with CloudFabric, that uses telemetry to monitor network health. The health function identifies various issues. Let's evaluate each option:
A . Switch ARP entry threshold exceeded: This is true. FabricInsight monitors ARP table usage and can detect when the threshold is exceeded, indicating potential resource issues. TRUE.
B . OSPF router ID conflict: This is true. FabricInsight can detect OSPF router ID conflicts, which cause routing instability, through health checks on control plane data. TRUE.
C . Switch CPU usage threshold exceeded: This is true. FabricInsight tracks device performance metrics, including CPU usage, and flags thresholds to prevent performance degradation. TRUE.
D . Routing loop on the network: This is true. FabricInsight analyzes traffic patterns and routing tables to identify loops, leveraging telemetry data for network-wide health assessment. TRUE.
All options A, B, C, and D can be identified by the health function of iMaster NCE-FabricInsight.
