Question 1

iMaster NCE-Fabric is Huawei's DC controller. Tenants can use it to create VPCs and deploy logical networks as required. After logical NEs are deployed, the corresponding network configurations are delivered to underlying network devices. Which of the following statements is false about the delivered network configurations?

ALogical switches are mainly used for Layer 3 communication between hosts on a VXLAN network. These switches correspond to Layer 3 gateway configurations such as VBDIF interface and VPN instance configurations on physical devices.

BAn end port represents an online host. It corresponds to the traffic encapsulation type (whether a VLAN tag is carried) configured on a Layer 2 sub-interface of a physical device.

CA logical port is equivalent to an independent physical port that is used by a host to connect to a VXLAN network. It corresponds to the Layer 2 sub-interface configuration on a physical device.

DLogical switches are mainly used for Layer 2 communication between hosts on a VXLAN network. These switches correspond to BD and Layer 2 VNI configurations on physical devices.

Answer : A

iMaster NCE-Fabric automates network configuration delivery in Huawei's CloudFabric. Let's evaluate each statement:

A . Logical switches are mainly used for Layer 3 communication between hosts on a VXLAN network. These switches correspond to Layer 3 gateway configurations such as VBDIF interface and VPN instance configurations on physical devices: This is false. Logical switches in iMaster NCE-Fabric primarily handle Layer 2 communication (e.g., bridging within a VNI), corresponding to Bridge Domains (BDs) and Layer 2 VNIs. Layer 3 communication is managed by gateways, not logical switches. FALSE.

B . An end port represents an online host. It corresponds to the traffic encapsulation type (whether a VLAN tag is carried) configured on a Layer 2 sub-interface of a physical device: This is true. End ports map to host connections, with encapsulation (VLAN-tagged or untagged) configured on sub-interfaces. TRUE.

C . A logical port is equivalent to an independent physical port that is used by a host to connect to a VXLAN network. It corresponds to the Layer 2 sub-interface configuration on a physical device: This is true. Logical ports represent host connections, mapped to Layer 2 sub-interfaces for VXLAN access. TRUE.

D . Logical switches are mainly used for Layer 2 communication between hosts on a VXLAN network. These switches correspond to BD and Layer 2 VNI configurations on physical devices: This is true. Logical switches facilitate Layer 2 connectivity, aligning with BD and VNI settings. TRUE.

Thus, A is the false statement because logical switches are for Layer 2, not Layer 3, communication.

Huawei's CloudFabric Solution supports various data center scenarios. Let's evaluate each option:

A . Container network: This is true. CloudFabric supports containerized environments (e.g., Kubernetes) with VXLAN and SDN integration. TRUE.

B . OpenFlow network: This is false. CloudFabric primarily uses BGP-EVPN and proprietary protocols, not OpenFlow, which is more associated with other SDN platforms. FALSE.

C . Hosting: This is true. CloudFabric is suitable for hosting environments, providing multi-tenant network services. TRUE.

D . Cloud-network integration: This is true. It integrates with cloud platforms (e.g., OpenStack) for unified management. TRUE.

E . Computing: This is false. While it supports computing resources, ''computing'' is not a primary scenario; it's an enabler (e.g., server connectivity). FALSE.

Thus, A, C, and D are application scenarios.

Question 3

In ZTP networking, which of the following addresses can be delivered by a DHCP server? (Select All that Apply)

ADefault gateway address

BSFTP server address

CDNS server address

DTemporary management IP address

Answer : A, C, D

Zero Touch Provisioning (ZTP) in Huawei's CloudFabric automates device setup using DHCP. Let's evaluate each option:

A . Default gateway address: This is true. DHCP can deliver the default gateway address to configure routing for the device. TRUE.

B . SFTP server address: This is false. SFTP server addresses are not standard DHCP options; they may be configured manually or via other protocols (e.g., TFTP for boot files). FALSE.

C . DNS server address: This is true. DHCP can provide DNS server addresses (Option 6) for name resolution during ZTP. TRUE.

D . Temporary management IP address: This is true. DHCP assigns temporary IPs (e.g., Option 50) for management during initial provisioning in ZTP. TRUE.

Thus, A, C, and D can be delivered by a DHCP server in ZTP.

Question 4

Which of the following statements are true about the Easy mode? (Select All that Apply)

AThis mode has low networking requirements.

BiMaster NCE-Fabric automatically generates configuration script files.

COn iMaster NCE-Fabric, you need to manually create and configure fabric resource pools, managed devices, device groups, device roles, tenants, and VPCs one by one in the Configuration Wizard menu.

DLayer 2 and Layer 3 basic services in a VPC are orchestrated on the Easy page.

Answer : A, B, D

The Easy mode in Huawei's iMaster NCE-Fabric simplifies network deployment for basic VXLAN fabrics. Let's evaluate each statement:

A . This mode has low networking requirements: This is true. Easy mode is designed for simple topologies (e.g., small spine-leaf networks) with minimal configuration complexity. TRUE.

B . iMaster NCE-Fabric automatically generates configuration script files: This is true. Easy mode automates script generation based on user inputs, reducing manual effort. TRUE.

C . On iMaster NCE-Fabric, you need to manually create and configure fabric resource pools, managed devices, device groups, device roles, tenants, and VPCs one by one in the Configuration Wizard menu: This is false. Easy mode automates these tasks, minimizing manual configuration compared to advanced modes. FALSE.

D . Layer 2 and Layer 3 basic services in a VPC are orchestrated on the Easy page: This is true. Easy mode supports automated orchestration of L2 (e.g., BDs) and L3 (e.g., gateways) services within a VPC. TRUE.

Thus, A, B, and D are true statements about Easy mode.

Question 5

In the CloudFabric Solution, SecoManager and iMaster NCE-Fabric are deployed independently. After SecoManager is installed, it needs to be manually interconnected with iMaster NCE-Fabric.

ATRUE

BFALSE

Answer : B

In Huawei's CloudFabric Solution, SecoManager (Security Manager) and iMaster NCE-Fabric (Network Controller) are components of the SDN ecosystem. SecoManager handles security policy management, while iMaster NCE-Fabric manages network orchestration.

Deployment: These components can be deployed independently but are designed to integrate seamlessly. Huawei's architecture supports automated interconnection after installation, leveraging northbound/southbound APIs or pre-configured integration workflows.

Interconnection: Manual interconnection is not required post-installation; the system automates the process once both are deployed and configured within the same management domain (e.g., via IP addressing and authentication).

The statement is FALSE (B) because interconnection is automated, not manual.

Question 6

Which of the following can be deployed to enhance DC reliability? (Select All that Apply)

APower supply redundancy

BM-LAG

CMonitor Link

DController cluster

Answer : A, B, D

Reliability in Huawei's CloudFabric data centers is enhanced through various mechanisms. Let's evaluate each option:

A . Power supply redundancy: This is true. Redundant power supplies (e.g., dual PSUs) ensure uninterrupted operation during power failures, a key reliability feature. TRUE.

B . M-LAG (Multi-Chassis Link Aggregation): This is true. M-LAG provides high availability by allowing active-active forwarding and failover between switches, enhancing network reliability. TRUE.

C . Monitor Link: This is false. Monitor Link is a Huawei feature for link status monitoring, not a direct reliability enhancement mechanism like redundancy or clustering. FALSE.

D . Controller cluster: This is true. A clustered SDN controller (e.g., iMaster NCE-Fabric) ensures high availability and failover, improving network management reliability. TRUE.

Thus, A, B, and D enhance DC reliability.

Question 7

Which of the following nodes connects computing resources such as virtual and physical servers to a VXLAN fabric?

ADCI leaf

BServer leaf

CBorder leaf

DService leaf

Answer : B

In Huawei's spine-leaf VXLAN fabric (e.g., CloudFabric), nodes have specific roles:

A . DCI leaf: Data Center Interconnect (DCI) leaf nodes connect different data centers, not internal computing resources. Incorrect.

B . Server leaf: Server leaf nodes connect computing resources (virtual servers via hypervisors, physical servers) to the VXLAN fabric, handling access traffic. This is the correct role for connecting servers. Correct.

C . Border leaf: Border leaf nodes connect the DCN to external networks, not internal computing resources. Incorrect.

D . Service leaf: Service leaf nodes connect to value-added services (e.g., firewalls), not directly to computing resources like servers. Incorrect.

Thus, the answer is B (Server leaf).
