Huawei HCIP-Data Center Network V1.0 H12-893_V1.0 Prüfungsfragen mit Lösungen (Q75-Q80):

75. Frage
An enterprise builds a DC and deploys iMaster NCE-Fabric to automatically deliver network configurations. After the engineer manually deploys the underlay network and delivers overlay network configurations through iMaster NCE-Fabric, it is found that tenant hosts cannot access external networks. Which of the following is not a possible cause of this fault?

Antwort: C

Begründung:
In Huawei's CloudFabric Solution, iMaster NCE-Fabric automates overlay network (e.g., VXLAN) configuration, while the underlay network is manually deployed. Tenant hosts failing to access external networks indicate a connectivity issue, likely at the overlay-underlay boundary or security layer. Let's evaluate each option as a possible cause:
A . No return route is configured on the PE: This is a possible cause. The Provider Edge (PE) device (e.g., border leaf or router) must have a return route to the tenant's VXLAN network for external access. Without it, traffic from external networks cannot reach the DC. POSSIBLE CAUSE.
B . The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model: This is a possible cause. Some Huawei switch models (e.g., CE series) require a service loopback interface as the VTEP source IP. If omitted or misconfigured based on the model, external connectivity fails. POSSIBLE CAUSE.
C . No firewall security policy is configured when host traffic passes through the firewall: This is a possible cause. If a firewall is in the path (e.g., between tenant VPC and external network), a missing security policy (e.g., allowing outbound traffic) blocks access. POSSIBLE CAUSE.
D . The MAC address of the NVE interface on the VXLAN network is not manually specified: This is not a possible cause. The Network Virtualization Edge (NVE) interface in VXLAN does not require a manually specified MAC address; it uses the switch's system MAC or auto-generates one. iMaster NCE-Fabric typically handles this automatically, and manual specification is neither required nor a common fault point for external access issues. NOT A POSSIBLE CAUSE.
Thus, D is not a possible cause of the fault.


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

Antwort: A,C,D

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.


77. Frage
Which of the following are the application scenarios of Huawei CloudFabric Solution? (Select All that Apply)

Antwort: C,D,E


78. 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.


79. Frage
Which of the following is not an advantage of link aggregation on CE series switches?

Antwort: D

Begründung:
Link aggregation, often implemented using Link Aggregation Control Protocol (LACP) on Huawei CloudEngine (CE) series switches, combines multiple physical links into a single logical link to enhance network performance and resilience. The primary advantages include:
Load Balancing Supported (B): Link aggregation distributes traffic across multiple links based on hashing algorithms (e.g., source/destination IP or MAC), improving load distribution and preventing any single link from becoming a bottleneck.
Increased Bandwidth (C): By aggregating multiple links (e.g., 1 Gbps ports into a 4 Gbps logical link), the total available bandwidth increases proportionally to the number of links.
Improved Reliability (D): If one link fails, traffic is automatically redistributed to the remaining links, ensuring continuous connectivity and high availability.
However, Improved Forwarding Performance of Switches (A) is not a direct advantage. Forwarding performance relates to the switch's internal packet processing capabilities (e.g., ASIC performance, forwarding table size), which link aggregation does not inherently enhance. While it optimizes link utilization, it doesn't improve the switch's intrinsic forwarding rate or reduce latency at the hardware level. This aligns with Huawei's CE series switch documentation, where link aggregation is described as enhancing bandwidth and reliability, not the switch's core forwarding engine.
