In Huawei CloudFabric Solution, iMaster NCE-Fabric uses SNMP to collect alarms and logs of physical
devices and vSwitches.
B
Explanation:
In Huawei’s CloudFabric Solution, iMaster NCE-Fabric is the SDN controller responsible for managing
physical devices and virtual switches (vSwitches). The method of data collection is critical for
network monitoring.
SNMP Usage: Simple Network Management Protocol (SNMP) is a traditional method for collecting
alarms and logs from network devices. However, Huawei’s modern SDN controllers, including
iMaster NCE-Fabric, primarily use telemetry (e.g., gRPC, NETCONF) for real-time data collection from
physical devices and vSwitches. Telemetry provides higher efficiency and granularity compared to
SNMP.
CloudFabric Approach: The solution leverages telemetry-based data collection, as documented in
FabricInsight and iMaster NCE-Fabric guides, to gather alarms, logs, and performance metrics. SNMP
may be supported as a legacy option but is not the primary method in this context.
The statement is FALSE (B) because iMaster NCE-Fabric predominantly uses telemetry, not SNMP, for
collecting alarms and logs.

"1-3-5" troubleshooting of the CloudFabric intelligent O&M solution can detect, locate, and rectify
faults from multiple dimensions. Which of the following are not dimensions supported by this
function? (Select All that Apply)
D
Explanation:
Huawei’s CloudFabric intelligent O&M solution, leveraging iMaster NCE-Fabric and FabricInsight,
uses the "1-3-5" principle (detect within 1 minute, locate within 3 minutes, rectify within 5 minutes)
to handle faults. This approach analyzes faults across multiple dimensions. Let’s evaluate each
option:
A . Device: This is supported. The solution monitors device-level metrics (e.g., CPU, memory) to
detect and locate faults. SUPPORTED.
B . Protocol: This is supported. Protocol issues (e.g., OSPF conflicts, BGP errors) are analyzed for fault
detection and resolution. SUPPORTED.
C . Service: This is supported. Service-level faults (e.g., tenant connectivity, VPC issues) are tracked
and addressed. SUPPORTED.
D . Application: This is not supported. The "1-3-5" troubleshooting focuses on network infrastructure
(devices, protocols, services, configurations), not application-layer issues, which are outside its
scope. NOT SUPPORTED.
E . Configuration: This is supported. Configuration errors (e.g., mismatched VNIs) are detected and
rectified as part of the process. SUPPORTED.
Thus, D (Application) is not a dimension supported by the "1-3-5" troubleshooting function.

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?
D
Explanation:
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.

Which of the following are advantages of iMaster NCE-FabricInsight's telemetry-based performance
metric collection? (Select All that Apply)
A, B, D
Explanation:
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.

Maintenance (O&M) capabilities. Let’s evaluate each option:
A. Multi-path detection: This is true. CloudFabric supports multi-path detection (e.g., using ECMP) to
verify load balancing and path diversity in the network. TRUE.
B. Network connectivity detection, such as IP ping and MAC ping: This is true. Tools like IP ping and
MAC ping are supported for troubleshooting connectivity between devices and endpoints. TRUE.
C. Single-path detection: This is false. While multi-path detection is supported, single-path detection
is not a distinct O&M function; connectivity checks typically involve multiple paths or end-to-end
verification. FALSE.
D. Visualization of entries (MAC/IP) on logical routers and switches: This is true. CloudFabric provides
visualization of MAC and IP entries on logical network elements, aiding in network management and
troubleshooting. TRUE.
Thus, A, B, and D are supported O&M functions.

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

In the computing scenario of Huawei CloudFabric Solution, which of the following services are
optional for controller interconnection? (Select All that Apply)
A, C
Explanation:
In Huawei’s CloudFabric Solution, the iMaster NCE-Fabric controller manages the network in
computing scenarios (e.g., virtualized environments). Controller interconnection with external
systems can be mandatory or optional depending on functionality. Let’s evaluate each option:
A. Interconnection with FabricInsight: This is optional. FabricInsight is an analytics and assurance tool
that enhances visibility and troubleshooting but is not required for basic controller operations in the
computing scenario. OPTIONAL.
B. Interconnection with the authentication server: This is mandatory. Authentication servers (e.g.,
RADIUS, TACACS+) are essential for securing access to the controller and managed devices, a core
requirement in computing scenarios. NOT OPTIONAL.
C. Interconnection with eSight: This is optional. eSight is a network management platform that
provides additional monitoring and management capabilities, but it is not necessary for core
controller functionality. OPTIONAL.
D. Interconnection with the VMM (Virtual Machine Manager): This is mandatory. Interconnection
with a VMM (e.g., FusionCompute, OpenStack) is required to manage virtualized computing
resources and orchestrate network services in the computing scenario. NOT OPTIONAL.
Thus, A (Interconnection with FabricInsight) and C (Interconnection with eSight) are optional services
for controller interconnection.

Explanation:
The Easy mode in Huawei’s iMaster NCE-Fabric simplifies VXLAN fabric deployment with automated
configuration. Certain pre-deployment steps are required. Let’s evaluate each option:
A. Disable data synchronization upon going online for the first time: This is false. Data
synchronization is typically enabled by default to ensure consistency; disabling it is not a standard
pre-deployment step and is optional based on specific needs. FALSE.
B. Load the license: This is true. A valid license must be loaded into iMaster NCE-Fabric before
deployment to unlock features, including Easy mode functionality. TRUE.
C. Pre-configure the access ports: This is true. Access ports on devices (e.g., server leaf nodes) need
to be pre-configured (e.g., with VLANs or basic settings) to ensure connectivity before Easy mode
automation begins. TRUE.
D. Configure an SSH fingerprint verification policy: This is false. SSH fingerprint verification is part of
security configuration but is not a mandatory pre-deployment step for Easy mode; it can be set post-
deployment or is automated. FALSE.
Thus, B (Load the license) and C (Pre-configure the access ports) are required operations before
deployment in Easy mode.

orchestration and management. It includes built-in servers to support its operations. Let’s evaluate
each option:
A. DNS server: This is false. iMaster NCE-Fabric does not include a built-in DNS server; it relies on
external DNS services for name resolution, configured during deployment. FALSE.
B. RADIUS authentication server: This is false. RADIUS authentication is typically handled by external
AAA servers; iMaster NCE-Fabric integrates with them but does not embed a RADIUS server. FALSE.
C. DHCP server: This is true. iMaster NCE-Fabric includes a built-in DHCP server to assign temporary
IP addresses during Zero Touch Provisioning (ZTP) or initial device configuration. TRUE.
D. Version file server: This is true. A version file server is built into iMaster NCE-Fabric to store and
deliver software images or configuration files for device upgrades and management. TRUE.
Thus, C (DHCP server) and D (Version file server) are built into iMaster NCE-Fabric.

In the VPC interworking scenario, traffic is checked and filtered only by the firewall in the source or
destination VPC.
B
Explanation:
In Huawei’s CloudFabric Solution, Virtual Private Clouds (VPCs) enable isolated network
environments, and interworking scenarios involve traffic between VPCs. The statement claims that
traffic is checked and filtered only by the firewall in the source or destination VPC. Let’s evaluate:
VPC Interworking: Traffic between VPCs can be routed via a gateway (e.g., a Layer 3 gateway or
centralized router) and may involve multiple security checkpoints depending on the design. Firewalls
can be deployed in the source VPC, destination VPC, or a centralized location (e.g., a service chain or
border gateway).
Firewall Role: The statement implies exclusivity (only one firewall), but in practice, traffic may be
filtered by firewalls at both ends, a centralized firewall, or additional security devices (e.g., VAS
nodes) in the path. For example, inter-VPC traffic might pass through a firewall in the source VPC for
egress filtering and another in the destination VPC for ingress filtering, or a shared firewall in a hub-
and-spoke model. Huawei’s security architecture (e.g., with SecoManager) supports distributed or
centralized filtering, not limited to a single VPC’s firewall.
The statement is FALSE (B) because traffic is not restricted to being checked and filtered only by the
firewall in the source or destination VPC; multiple firewalls or security devices may be involved.

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?
A
Explanation:
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.

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.

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.

Which of the following statements are true about the Easy mode? (Select All that Apply)
A, B, D
Explanation:
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.

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.
B
Explanation:
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.
